Review Biometrics Technologies Measure Up Part 33

first_img How Ghana is acing its transition to mobile financial services Pattern RecognitionNot commonly recognized among the biometric technologies but widely used and gaining in popularity is the technique of behavior recording. These systems are computer programs that monitor particular behaviors like typing and purchasing to identify users.Credit card companies, for example, have records of your purchasing patterns. Any unusual purchases are flagged by a computer program and brought to the attention of a customer service representative who verifies the authenticity of the purchaser.They way you type – frequency of keystrokes and their duration – has been proven to be a very effective way to identify unauthorized users on computer networks.Internet sites you visit, programs and files you use and general work patterns can all be analyzed to prevent hackers from stealing sensitive information.The big advantages to this approach include low cost, high effectiveness and unobtrusive operation – most users are completely unaware of the software’s operation.ConclusionThe sharp increase in identity theft and the threat of terrorism combined with the falling prices of all biometric technologies, it’s predicted that the biometrics industry will explode as demand increases sharply in the next 3 to 5 years. Already many systems are in use and technology is improving to eliminate false positives that may have deterred buyers in the past.New inventions tend to cause backlash, but biometrics technologies, especially the clandestine ones, have provoked storms of protest from privacy groups and users. This may slow, but not stop rapid adoption. All experts agree more need to be done to address ethical and privacy concerns.Like the adoption of any new technology, there are many problems that still remain to be fully overcome, but the idea of an ID-less society is not far off. The sheer convenience, low cost and security are very attractive to businesses, governments and users alike.Who knows? One day you may be able to go about your business never having to present any form of artificial ID. Biometrics systems promise to make huge changes in the way we do business and identify ourselves. They also promise to invade our already beleaguered privacy and create a new breed of sophisticated criminals adept at hacking our biometric identities.Part 1, 2Copyright 2005 PhysOrg.com This document is subject to copyright.

French team demonstrates paramagnetic properties of liquid oxygen drops

first_img More information: Magnetic control of Leidenfrost drops, by Keyvan Piroird, Christophe Clanet, and David Quéré, Physical Review E, Accepted Monday Apr 30, 2012AbstractWe show how a magnetic field can influence the motion of a paramagnetic drop made of liquid oxygen, in a Leidenfrost state on solids at room temperature. It is demonstrated that the trajectory can be modified both in direction and velocity and that the results can be interpreted in terms of classical mechanics as far as the drop does not get too close to the magnet. We study the deviation and report that it can easily overcome 180 and even diverge under certain conditions, leading to situations where a drop gets captured. In the vicinity of the magnet, another type of trapping is observed, due to the deformation of the drop in this region, which leads to a strong energy dissipation. Conversely, drops can be accelerated by moving magnets (slingshot effect). Journal information: Physical Review E Droplets levitating above a liquid surface show unusual motion (w/ video) Leidenfrost drops come about when a liquid is dropped onto a surface that is significantly hotter (above its boiling point) than it is, trapping vapor underneath which allows the drop to not only avoid instant evaporation, at least right away, but to hover over the surface. The effect is commonly seen when water is tossed into a hot pan; the drops that form move around faster than they normally would due to the absence of friction.Leidenfrost drops are used in a variety of industrial processes despite a lack of research into their physical properties. To learn more, the research team from Ecole Polytechnique looked to liquid oxygen drops because of their room temperature boiling point and also because they are paramagnetic and very easy to make.To make drops of liquid oxygen, the team poured liquid nitrogen into a metal container. As they did so, drops of liquid oxygen formed on the outside of the container due to condensation. Once the drops were produced, the team put them on a glass plate where under normal conditions they would slide around chaotically as water does in a hot pan. To control them, the team placed a small magnet underneath the glass.The team found that by moving the magnets they could control the paths the drops took and that angling the magnet caused different behavior; some were deflected while others swooped around the magnet, emulating the sling-shot effect scientists use to fling spacecraft away from a planet towards an established destination. Through trial and error they also found that in some instances they could cause the drop to actually orbit around the magnet.Interestingly, the group also found that the degree of friction involved with the drops appeared to fluctuate depending on the shape of the drops as they moved around, which might just lead to better processes for controlling Leidenfrost drops in industrial applications.The team believes their research might also lead to space travel modeling as the actions of the drops they manipulated with their magnets so closely mimic that of actually space travel situations. To further their research they have begun adding different particles to the drops to see how different materials impact their behavior.

Credit: doi:10.1371/journal.pone.0107456.g001 Explore furthercenter_img Saber-toothed cats have sparked the imagination of generations of children and adults alike, with their very long canines, the animals continue to strike fear in people to this day, despite the creatures being extinct for approximately 10,000 years. Over the years, scientists have offered various ideas to describe just how exactly the cats used their long teeth to bring down prey. Initial theories suggested they simply jumped on the backs of other animals and slashed at them with their teeth (hence the name saber) till the unfortunate victim died. A closer look revealed that such an approach was highly unlikely due to the toughness of the hide sported by most prey of the time, and the degree of muscle in the cats’ neck.More recently paleontologists came up with a theory called the “canine shear bite” which proposes that the cats jumped on the backs of victims first puncturing the skin with its lower jaw and then leveraging the neck to allow for slicing down into the victim with the long teeth. Brown claims this method wouldn’t work either because it wouldn’t generate enough force. He proposes that the cat’s first dug in just slightly with the lower jaw, for use as a lug, like a can-opener, then pushed mightily against the ground with their forelimbs. Such an approach, which Brown calls a “Class 1 Lever Model” would allow the cat to use the muscles in its legs, back, neck and jaws to bring down prey, providing much more leverage and force.Brown suggests further research, such as computer simulations would prove his idea correct, and furthermore, would likely explain the hunting techniques of most if not all of the “saber” beasts that once roamed the Earth killing with their massive teeth. More information: Brown JG (2014) Jaw Function in Smilodon fatalis: A Reevaluation of the Canine Shear-Bite and a Proposal for a New Forelimb-Powered Class 1 Lever Model. PLoS ONE 9(10): e107456. DOI: 10.1371/journal.pone.0107456AbstractThe jaw function of Smilodon fatalis has long been a source of debate. Although modern-day lions subdue large prey through the use of a suffocating throat bite, the dramatically elongated maxillary canines of S. fatalis suggest an alternative bite mechanism. The current literature favors a “canine shear-bite,” in which the depression of the cranium by the ventral neck flexors assists the mandibular adductors in closing the jaws. Although the model makes intuitive sense and appears to be supported by scientific data, the mechanical feasibility of “neck-powered” biting has not been experimentally demonstrated. In the present study, the computer-assisted manipulation of digitized images of a high-quality replica of an S. fatalis neck and skull shows that a rotation of the cranium by the ventral neck flexors will not result in jaw closure. Instead, the cranium and mandible rotate ventrally together (at the atlantooccipital joint), and the jaws remain in an open configuration. The only manner by which rotation of the cranium can simultaneously result in jaw closure is by an anterior rotation at the temporomandibular joint. Based on this finding, the author proposes a new Class 1 lever mechanism for S. fatalis jaw function. In this model, the mandible is immobilized against the neck of the prey and a dorsally directed force from the extension of the forelimbs rotates the cranium anteriorly at the temporomandibular joint. The maxillary canines pierce the prey’s neck and assist in clamping the ventral neck structures. The model is based on a maximum gape angle of approximately 90° and incorporates a secondary virtual point of rotation located slightly anteroventral to the temporomandibular joint. The Class 1 Lever Model is mechanically feasible, consistent with current data on S. fatalis anatomy and ecology, and may provide a basis for similar studies on other fossil taxa.

Brown has self-published a paper on the open access site PLoS ONE, detailing what he believes is the correct interpretation of how the now extinct saber-toothed cat brought down its prey.

Art for the Aam Admi

first_imgCommon entails a group exhibition of paintings and sculptures.The term common (AAM)  is a wide fledged word these days in both political context and Bollywood industry. The core motto of this exhibition is to décorate the houses with affordable quality paintings and artworks. These days starting from a very middle class family to elite class people are generating an interest towards art and in housing art. However, buying art is again just not simple as buying some other confectionery or stationary stuffs. It includes sentiments and personal attachment along with budget which again goes as one of the major constraint.  To overcome these discussed factors consultants from Creativity Art Gallery are going to show case their new collection of art works by fair established names but in affordable prices. The collection will carry various ranges of paintings and sculpture in affordable traveling range of prices. The range is tentative to start from 15 thousand to 1 lakh. The aspects of colour and happiness would be the core hold for the show.WHEN: 10-30 MarchWHERE: Common Creativity Art Gallery, 29, GF, Hauz Khas Villagelast_img read more

SIT set up to probe into murder of Sheikh Dildar

first_imgKolkata: A special investigation team (SIT) has been set up to probe into the murder of Trinamool Congress worker Sheikh Dildar, besides changing the Investigating Officer (IO) of the case. He was shot dead in Suri in Birbhum on Monday over a fallout during the filing of nomination of the Panchayat polls.Sources said both the steps that is to form an SIT and to change the IO were taken to expedite the process of the investigation.The new IO of the case is the inspector-in-charge Debashis Panda. Earlier, sub-inspect, Soumo Dutta, was the IO of the case. Also Read – Heavy rain hits traffic, flightsThere are senior officers of Birbhum District Police and Suri police station in the SIT. The SIT will take necessary steps so that the probe can be expedited and they would get to know about others involved in the incident. It is learnt that there was not much development in connection with the recovery of firearms used in the incident and it could be the reason that has prompted the change in the IO. Moreover, there are also involvement of miscreants from Jharkhand who were deliberately brought to create ruckus in Suri. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedIt may be recalled that Firhad Hakim, senior Trinamool Congress leader and the state Urban Development and Municipal Affairs minister, had said on the day of the incident that a group of miscreants from Jharkhand was brought in to create trouble and he had alleged that they were brought in by the BJP. “The group that created trouble at Mohammadbazar and Nalhati was also behind the incident at Suri,” he said.Police are also looking into the matter and it is learnt that a team of policemen will be visiting Jharkhand to get hold of the miscreants. It may be mentioned that four BJP workers were arrested on Wednesday in connection with the incident.Police had conducted a raid at Koridha in Suri after receiving a tip off and arrested Sheikh Safiul, Gautam Kora, Bablu Sheikh and Asit Sarkar. All four were produced before the court and the police had pleaded for 10 days’ custody for all four of them. However, the court decided to remand to police custody for seven days.last_img read more

Will enlarged pictorial warnings reduce tobacco consumption

first_imgBut this is still not enough to reduce the consumption rate among the majority of habitual smokers, say stakeholders and experts.The Supreme Court recently ordered cigarette producers to comply with the health ministry’s new regulation mandating an increase in the size of the pictorial warning to 85 percent of the front and back panels of cigarette packets.However, many regular smokers who don’t buy full packets admitted that they are unaware about the order. “I have not seen the enlarged warnings as I don’t buy packets, but one or two cigarettes at a time,” said Vikash Shaw, who smokes about eight cigarettes a day. Terming the enlarged warnings as “futile”, Babu Hazra, a daily wage labourer, said: “What matters to me is only the sudden price rise.” Also Read – ‘Playing Jojo was emotionally exhausting’Leading cigarette producer ITC has retained the prices of most of its brands but reduced the stick sizes to overcome the 10-15 percent hike in tobacco taxes that was announced in this year’s union budget.Serviceman, Amitava Bhatacharya said although initially the enlarged warning looked scary, it could not stop him from smoking. “When I first saw that big warning image, I was indeed terrified. But eventually I surrendered to my addiction,” said Bhattacharya. Also Read – Leslie doing new comedy special with NetflixCigarette retailers too testified they have not seen any significant change in consumption rates.However, cigarette producers have complained that India’s legal cigarette industry is facing a continuous drop in demand because of high taxation and large pictorial warnings.Dhaneswar Patra, a roadside paan-waala, said, “Even before these warnings were printed on the packets, smokers knew that it is harmful. But still they consumed cigarette at their own will. The same is happening now too.” On the other hand, doctors and economists are giving a thumbs up to the new regulations. With almost one million people dying due to direct and passive smoking in India, medico S.K. Paira believed quitting tobacco is comparatively easier than other addictions.“Smoking creates mental dependency while alcohol and drugs create physical dependency in which withdrawal symptoms are fatal. Mental determination is the best way to give up smoking,” said Paira.Admitting that the overpowering craving for tobacco makes regular smokers overlook health warnings, psychiatrist Manoj Sharma felt that the enlarged pictorial warning has to be complemented with grass-root level awareness for reducing tobacco consumption. “Education at the school level is necessary for creating awareness about the ill-effects of smoking. Reducing tobacco consumption depends on the interplay of these two factors,” said Sharma.Economist Santanu Mitra said: “The enlarged warning may serve as a discouraging factor for first time smokers and those who are not regular or habituated smokers.” Papiya Sen, an anti-tobacco activist, accepting the fact that the message of the perils of smoking is not reaching out to the larger public who smoke beedis since there is no compulsion to cover 85 per cent of the beedi packets with pictorial warning, said: “We have to take one step at a time. I am sure sooner or later we will succeed in making the beedi companies print enlarged warnings too.”Statistics have shown that beedis account for 48 per cent of India’s tobacco consumption.last_img read more

Research has proven that, as opposed to the previous beliefs, eggs are actually good for health. Researchers have looked at the diets of people, and they have suggested that consuming eggs every day is not associated with cholesterol problems or heart disease. Eggs are low in saturated fat and they have no trans-fat, only a small amount of cholesterol. Most of the fat present in the eggs are the ‘good’ unsaturated fat.Take a look at some of the common myths and find out the fact behind them.

The Superfan who Left her Entire Fortune to Charles Bronson

first_imgCelebrities often receive strange and extravagant gifts from their loyal and enthusiastic fans. However, one of the most generous fan gifts in history was given to the Hollywood star, Charles Bronson. In 1996, a woman from Louisville decided to leave her entire $300,000 fortune to Bronson, her favorite actor, in a handwritten will. According to the New York Post, Audrey Knauer passed away in 1997 at the age of 55, leaving behind an estate worth $300,000. However, in a surprising turn of events, it was discovered that she had willed her entire fortune to Charles Bronson, in a handwritten note.Publicity photo of Charles BronsonThe will hastily scribbled on the back of a list of emergency numbers, expressly stated that none of her fortune was to go to her family as she had originally intended. Rather, she wished her entire estate to go to her favorite actor, Charles Bronson, whom she had always admired.Bronson as Dan Shomron in Raid on Entebbe (1977)According to E-Online, Knauer is said to have written, “Under no circumstances is my mother, Helen, to inherit anything from me – blood, body parts, financial assets, etc. I bequeath to Charles Bronson, the talented character actor, and what he doesn’t want, he can pass thru (sic) to the Louisville Free Public Library”.Louisville Free Public Library. Photo by Sfan00 CC BY 2.5Knauer had never met Bronson, but she was an avid watcher of his films and kept a collection of newspaper clippings that referenced him. She particularly enjoyed watching his Death Wish films, and regularly rented them from the Louisville Free Public Library.After her death, a portion of Knauer’s estate went directly to Bronson. However, the will was later contested by her remaining family, represented by her sister, Nancy Koeper, when they realized the size of the bequest.Photo of Charles Bronson as Mike Kovac from the television program Man With a Camera.It was suggested that Knauer was not psychologically stable when she wrote the will bequeathing her estate to Bronson. Instead, the family presented an earlier document, signed and witnessed by Knauer in 1977, which they argued should supersede the handwritten will. In this earlier testament, Knauer had ordered that her estate was to be divided between her relatives upon her death.Koeper argued that Knauer was incapable of taking the decision to leave all of her possessions to Bronson, suggesting that she was not in sound mind when she wrote the will. She suggested that Audrey was obsessed with Bronson, to the point of mania. She obsessively followed his movies and his public life, spending hours in the public library searching for information about him.Photo of Charles Bronson as Linc, the wagonmaster, from the television program The Travels of Jaimie McPheeters.Koeper described her sister’s obsession as a search for a father figure, adding that Knauer had been attracted by the idea of Bronson as an avenging hero. Describing Knauer’s difficult life, she suggested that her fixation with Bronson was born out her own need to seek justice and revenge.Koeper and Bronson were not, however, the only parties that stood to gain from Knauer’s unusual bequest. Her note stipulated that should Bronson not wish to keep the money, it should be donated to the Louisville Free Public Library.Charles Bronson and Patricia Owens in the film X-15 (1961) – publicity stillBronson had originally suggested that he was going to donate all of the money to the library. This would have constituted one of the largest gifts in the institution’s history.Speaking to the New York Post, library director Craig Buthod noted that this would have a profound effect on the services the library was able to offer the local community. The bequest would allow them to buy 20,000 new books, or to keep the summer reading program going for several years.Apparently, Bronson did offer the library $10,000, but they declined this offer, hoping that they would stand to gain much more in the event of a successful appeal. However, Bronson and Koeper eventually settled out of court for an undisclosed sum, and the library ended up with nothing.Read another story from us: Eric Clapton Grew up Thinking his Mother was his SisterWe will never know if Audrey Knauer was in fact of sound mind when she wrote her will bequeathing her estate to Bronson.

VIDEO President Trump posthumously pardons Jack Johnson the first African American heavyweight

first_imgFor those that aren’t familiar with Johnson’s accomplishments in the ring, he was an athlete ahead of his time who physically dominated the majority of his over matched opponents. Johnson’s 1910 fight against Jim Jeffries was hyped as ‘The Fight of the Century’ and was essentially boxing’s first mega fight. Here’s some video of him in action. Today, President Trump has issued a posthumous pardon of Jack Johnson, the first African American heavyweight boxing champion, more than a century after he was convicted under federal law for having relationships with white women.Johnson was arrested under the Mann Act, a law which made it illegal to ‘transport women across state lines for moral purposes,’ on two occasions for the having ongoing relationships with two white women who were alleged to be prostitutes by authorities. He was eventually convicted by an all-white jury in the courtroom of future baseball commissioner Kennesaw Mountain Landis and sentenced to a year and a day in prison.Following his conviction, Johnson actually skipped bail and lived abroad for seven years before eventually returning to surrender to authorities and serve his sentence.His arrest and conviction are largely viewed as unjust and racially motivated as a measure of revenge for his status as an outspoken African American celebrity in the Jim Crow Era. President Trump said he issued the pardon after it was brought to his attention by Sylvester Stallone, who was present at the signing ceremony along with some members of Johnson’s family..last_img read more

New Tools and Tactics for a Killer Presentation

first_imgOctober 17, 2011 “How you connect to your listeners and the adjustments you make based on their reception is what makes the presentation work.” –Whitey BluesteinPhoto© Eva KolenkoQ: What are the best tools and methods for killer presentations?A: Leaving everything up to PowerPoint is not really an option anymore (if it ever was). No number of creative infographics, nifty tools or new gadgets can save your presentation if you don’t have a good understanding of your audience and a strong desire to engage with them.”I always come back to the notion that the best presentations are based on the value of the content, the skill of the delivery and the charisma of the speaker,” says Whitey Bluestein, a strategic advisor to mobile companies and other technology startups. “As a presenter, how you connect to your listeners and the adjustments you make based on their reception is what makes the presentation work.”Bluestein often presents to clients in a variety of situations and to various group sizes–and the early stage companies he works with do the same. Although he does use PowerPoint, it’s mostly to organize his thoughts. “PowerPoint has its place, but it is cursed as much as it is praised,” he says. “It’s tight-scripted and very one-way. When I present, I feel it has to be interactive. I would create a PowerPoint, but make it available as a leave-behind.”Bluestein suggests that one of the best general technology tools a speaker can adopt is actually a medium: video.”A lot of companies can just make a YouTube video demonstrating their product, and it’s a great thing to show people,” he says. “I have seen companies try to do live demos at big shows, and sometimes it doesn’t work because you don’t have control of everything. A video is cheap and easy to do in an environment where you have control.”The most valuable specific technology tool for presentations may be the iPad, Bluestein says. “It’s easier to travel with, and easier to share, and there are apps you can use during your presentation.”Here are some iPad apps Bluestein suggests trying out for your next gig:Idea Flight: This app allows a pre-senter to become a “pilot,” sharing a presentation with a group of users and having them follow along on their own iPads. Bluestein likes the idea behind it but notes that it’s limited to situations where everyone has an iPad.Evernote: Bluestein uses Evernote, one of several personal file organization apps for the iPad, to easily store a document and quickly retrieve it later to share during a presentation.join.me: This app from LogMeIn enables screen sharing among iPads, similar in some ways to WebEx.Keynote: The Mac world’s version of PowerPoint has all the enabling features for creating presentations that also can be converted to or from PowerPoint.Aside from iPads, some of the more traditional tools of the presenter continue to change. Portable projectors are helpful, Bluestein says, and have come down in price and form factor in recent years. Laser pointers now come stocked with more capabilities, like Bluetooth connectivity and USB storage.The apps and gadgets, however, don’t come with a method for lengthening a rapidly shortening audience attention span. “You have to wonder what the standard for presentations is going to be in five years,” Bluestein says. “Increasingly, people want them to be brief. They want to touch and feel what you’re telling them about, and they want to do it now.”  This story appears in the October 2011 issue of .

Before You Download That App What You Need to Know About Security

first_imgApril 9, 2012 Growing a business sometimes requires thinking outside the box. 5 min read Opinions expressed by Entrepreneur contributors are their own. Register Now » Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global An entrepreneur’s smartphone and tablet are stuffed with sensitive information, from customer lists to business strategy notes. Loss or theft isn’t the only way it can fall into the wrong hands. Cyberthieves and unprincipled or ignorant companies could use apps to take data without your even realizing it.Mobile apps — whether for business or entertainment — can upload your contact lists and access your location and email, though in almost all cases you must give them permission to do so. They may also store personal and other sensitive information, and sell it or share it, without your knowledge.Your phone is “highly personal and facilitates a huge level of data collection,” says Sarah Downey, a privacy analyst at Abine Inc., a Boston-based privacy software firm. You owe it to yourself, your business and your clients — especially if your company promises them confidentiality — to keep your devices free of malicious apps and to put privacy protections in place.Here are five tips to consider before downloading a new app on your device:1. Shop wisely. Despite the media hype, malware on mobile devices is not yet a significant problem. Although malware incidents are on the rise, the majority involve apps acquired from random, untrustworthy websites. Most have targeted the Symbian operating system and, more recently, Android. You can reduce your risk of downloading an outright malicious app to almost zero by acquiring apps only from your operating system maker’s app store.Related: Three Tips for Keeping Business Data Safe on Personal Mobile Devices Google scrutinizes the security of apps sold through Google Play (formerly the Android Market), takes user complaints and removes apps that violate its policies. Apple also vets apps before allowing them to grace its App Store which, experts say, has never distributed a malicious app. Microsoft does the same in its Windows Phone 7 marketplace.2. Be cautious. Before downloading an app from a company you’ve never heard of, do a quick web search to make sure it’s legitimate and reputable. People love to complain online, and their grumbles could protect you from a bad actor — or a sloppy newcomer that ignores user privacy.3. Be socially discerning. Don’t use your personal Facebook or Twitter account to sign in to a business app. “You want to keep a separation between church and state,” says Pam Dixon, executive director of World Privacy Forum, a San Diego-based advocacy group. “We don’t know all the dangers yet … You need to make sure client data is not getting sucked in [to social networks]. It could be a real competitive issue down the road.”4. Demand privacy. Don’t buy an app it if requires permission to access data or take other actions you find intrusive or unnecessary. Few apps need your contacts list or physical location. Even fewer need to access your emails, send text messages or listen in via your microphone.App developers often seek more permissions than they need in case they might want them for a new feature down the road, Downey says. Many apps don’t have privacy polices (though more will soon), and they often fail to disclose or are vague about how they’ll use your data.Related: Nine Tools for Building Your Own Mobile AppAlso, check privacy policies, the documents that give you legal recourse if data are misused. You can use your computer to visit the app store, find the app and click through to the developer’s site to look for the policy. If necessary, email the app maker for more information. Does your note-taking app store a copy of your scribblings on its own servers? Does your project planner transmit your client list?If you’re not comfortable after your due diligence, don’t install the app and let the maker know why. Mobile privacy is new territory that’s beginning to get public, corporate and government attention.5. Check your existing apps. It isn’t quick, easy or fun, but it is helpful to review the privacy policies and permissions given to apps you already own.Android users can review permissions for individual apps by going to the Settings screen and choosing Device and then Apps. Both Android and iPhone let you adjust or totally turn off their GPS location features within settings. With iPhone, you can see which apps access location and turn each one on or off. Apple plans to provide a similar tool for adjusting permissions to access contacts lists in a future operating system update.Related: Three Ways to Make Your App Stand Out (Video)Independent resources for understanding app privacy and security are limited. WhatApp.org has some useful expert reviews but covers a very small number of apps. Common Sense Media reviews games and other apps popular with kids.Concerned users may want to consider security software to defend against mobile malware, including spyware apps like FlexiSPY, which are most often planted by jealous lovers but presumably could be installed by corporate spies.Lookout Inc., a mobile security software maker, offers Privacy Advisor as part of its premium security software package for Android phones and tablets ($3 a month or $30 a year). Privacy Advisor provides a list of which of your apps can access private data, along with reports that explain the risks and capabilities of each app.last_img read more
