A new app available in the Chrome Store called Secretbook, which helps you to encoding messages into pictures that you then upload to Facebook. This extension for Google Chrome browser protects secret messages to the public and governments, says the text description of the app. Its author is Owen Campbell-Moore, a computer science student at the University of Oxford and also intern at Google. To use the application is simple, just upload a photo JPEG format at least 960 × 720 px preferably (for best quality) and avoid putting pictures with large identical parts (sky background solid color). Then enter your message and set a password for your friends to read it. Once the image is created with Secretbook, you just put it in a Facebook album or on the wall of your friend. The art of steganography is not new, and indeed perhaps the word reminds you of the story of the 10 Russian spies arrested in the United States in 2010? There are already tools to hide coded messages in images on Facebook but they were more complicated. Owen Campbell-Moore had to reproduce the images recompression algorithm used by Facebook.

Facebook makes you Childish!
"Facebook can change our brain" - warns Neuroscientist Susan Greenfield of Oxford University (UK). In the British "Telegraph" she says, not only that we give up our individuality through social networks, but also our way of thinking is modified as childish. Especially "Facebook Home" - the new user interface, in which you get instead of the usual apps and widgets, updates of your Facebook friends on the home page of your smart phones immediately- it deems objectionable. At first glance, "Facebook Home" seems harmless: One knows immediately what is going on with friends and what photos they have just posted. But exactly this we are always obsessed! Obsessed to monitor the lives of others and at the same time to hold every moment of one's existence in the social network; simply addicted to the social network. We hurt ourselves above all, more precisely, our individuality, says Greenfield. Mark Zuckerberg has decided "Facebook Home" for the time being only for Android.
In an interview with the magazine "Wired" said Mark Zuckerberg, why own a Smartphone for Facebook is not worthwhile. Permanent get shown the lives of others, puts pressure on us to also perform a digital super-life, rather than preserve privacy. Our brain is so to speak slowly reprogrammed from "individualist" to "public joint stock man." "The human brain is superior to the other species, since it has the unique ability to adapt to its environment - it's sort formable. Since we live in an ever-expanding world of digital, we are permanently trimmed to alert what other people are doing (in which case our Facebook friends) or just think that they currently represent. This our way of thinking, our attitude for too many things will change. " The fatal consequence, according to Greenfield: Our way of thinking is rather childish, depending on the behavior and thoughts of others. We ACT instead of REACT.
Define ourselves by "Like" data and the number of responses to our postings. Moreover, we do not take the time to reflect inwardly as we are at certain things, but be guided by the opinion of the crowd. Our experiences are only exciting, interesting or bizarre was when our digital friends also find - and comment accordingly. Although we consider all of our privacy as the highest good, we give them in total to complete network to be part of the community. To "Like" information gathering, we provide cheap photos, memories and desires. We prefer to respond quickly to a posting, as we take the time to, first of all think about how we actually find it. According to Greenfield, we thus develop a new identity - and an over-networked, community identity. The danger: Just as the community sees us, we finally see each other.

Facebook Home for Android and Smartphones!
Facebook unveils Home, "which is not a phone or operating system, but is an application", explains the social network. It is an overlay for Android that puts in the heart of the social network phone. The outline of Home had leaked in recent days. This overlay for Android & Smartphone built by HTC is not a surprise. Facebook Home will be available on Google Play, from April 12, as a single application.

You can scroll to see the feed cover various activities and if you want to "Like" an item, just do double tap it. For larger notifications, as a message from one of your friends on your timeline, the message is displayed with the profile photo of your friend messaged.
A tap on the photo opens the notification; it is also possible to hide. Facebook Home provides access to instant messaging wherever you are. When receiving a message on Facebook, the photo of the friend behind the message over the application in use. Applications other than those signed by Facebook are of course available from a launcher. Facebook Home will be compatible at its output with a handful of high-end devices: HTC One, HTC One X, HTC One X +, Samsung Galaxy S III, Galaxy S4 and Galaxy Note II.
The social network announced that other Smartphones will support the overlay in the coming months. Mark Zuckerberg also announced that Facebook Home Program, a program for mobile manufacturers to support the overlay social network. HTC of course subscribe to this program, and there are also Samsung, Sony, ZTE, Lenovo, Huawei and Alcatel One Touch as manufacturers. It is not clear at this time whether these companies will release a Smartphone with Facebook Home preinstalled or allow the installation of the software on their products.

Facebook flaw: the photos of Mark Zuckerberg hacked
Mark Zuckerberg is the victim of a security problem on its own social network. Many of her private photos were found published after the discovery of a vulnerability in Facebook profiles.
Published on the forum site of bodybuilding, the method of access to private photos is very simple. Just see the pictures of a person as spam (even if you are not friends with her). Facebook proposes to report the offending photos and displays the images of the private individual.
It was enough that the principle is applied directly to the profile of Facebook founder and several of its private photos can be found posted on the Web.

Facebook monitors 51% of online purchases
A recently published study by the firm Sociable Labs shows that 51% of online purchases are made not of users who are connected to Facebook at the time of purchase. This allows the social network to collect an additional data on these users about their shopping habits.
More than half of online shoppers are also connected to Facebook when making a purchase. Most commonly, it is thanks to Facebook Connect, which allows the social network to collect data on the navigation of its members. This has two advantages for Facebook, as commerce sites.

Anonymous attack
Anonymous declares war on an internal group whose actions would be more faithful to the beliefs of the hackers group. Anonymous seems to have more than enough of a few renegades who use his name to initiate actions that the group does not endorse. The attack on Facebook these days, and claimed by some people claiming to belong to Anonymous seems to have been too much for the scope of the group, who decided to respond.
It's a smaller group, claiming to Anonymous and named "AnonOps," which is the center of the controversy. AnonOps is accused of being "gone to the dark side" and being "blind with power who treat newcomers with contempt and arrogance instead of fighting corruption and censorship on the Internet," says Anonymous.
