HP And 3M Team Come Up With Solution To 'Visually Hacking'

Computer giant HP is adding privacy screens from 3M's own laptops, so as to avoid "visual hacking."As more and more PCs are used in public places, is visually hacking, collecting confidential information by looking at the screen of another, a high security risk," said HP CEO Alex Cho.

According to Herve Gindre 3M is visually hacking a growing problem. In addition to being a study sponsored by 3M (pdf) noted that early this year and was published which showed that almost 90% of attempts to steal sensitive corporate data by only 'visual aids' is successful. To prevent this, 3M created a privacy screen that the limited viewing angles, so that others can not observe.

The company has also developed filtering software that acts as a rear and uses face detection and webcam. Once someone is watching over the shoulder, the software saves alarm. The software can also obscure the image when the user sits at his computer. Shoulder Surfing, as the watch is also called, is already a very old phenomenon. In 2007, in this way the credit card information stolen from more than 11,000 Americans. In 2013, the security chief of Microsoft even called shoulder surfing a greater risk than counterfeit fingerprints.

Payment Processor To Test Facial Recognition Pins

Payment Processor Worldpay has developed a camera that uses face recognition to debit card payments. Once the consumer settles and enters their PIN, the camera in the payment terminal picture. This picture is then compared with the photos stored in the database of Worldpay.

With each transaction where the PIN is entered makes the "PED Cam" (Pin Entry Device Camera - pdf) namely a new picture of the consumer, so as to improve the identification. The created image is then compared with a biometric template which is previously stored. This should provide a second layer of authentication by verifying the identity of the card user.

The now-developed prototype is made up of low-cost, available technology and, according to the developers of the British Worldpay several advantages over other biometric security measures. So users do not have to register separately for the system, because they automatically enter the system when they use their debit card.

At present, the British consumer response are examined that have participated in a test of the system, and how consumers can subscribe to the biometric system. Also, see the researchers or the biometric profile that stores the payment terminal can be used to identify Internet users.

Researchers Develop Face In The Dark

Face recognition is increasingly used, biometric access control to the "tag" photos on social media, but the systems that are actually responsible for this work only during the day and with sufficient light. However, German scientists have now found a solution to face in the dark possible.

Saquib Sarfraz and Rainer Stiefelhagen of the Karlsruhe Institute of Technology have developed a system ( pdf ) developed whereby they analyze dozens of infrared images of a person's face and then compare dozens of images taken in daylight.Researchers feel that the differences in lighting one of the biggest problems that face is facing. Infrared has the advantage that it is insensitive to the present exposure.

In order to compare the images, the scientists have developed a program that uses a "deep neural network system," in order to mimic the operation of a human brain. Through this neural network were over 4500 images which were both made in infrared and daylight are compared within 35 milliseconds to find a match. However, the system also has its problems. As daylight influence can have the photo of someone's face, may infrared images by environmental influences also differ. If it's hot outside or someone have exercised the visions if this person is cool and relaxed.

In the comparison of more than 4500 pictures we worked with 82 people. In 80% of the cases, the match was between the picture in daylight and infrared image correctly. This however requires that there were available several pictures. In case there was only a picture in daylight available, the accuracy decreased to 55%. However, performance can be improved with a larger dataset and powerful network. The conclusion of the study the researchers argue that their approach provides a very practical solution for large-scale surveillance and military applications. They are namely governments, enforcement agencies and the military who may have these datasets and networks.

AVG Demonstrates Privacy Glasses To Face

Early this month unveiled the Czech anti-virus company AVG privacy glasses designed to prevent face and now the virus fighter has a demonstration online put. The glasses are developed because it more and more places appear cameras and face recognition develops.

It involves, for example pictures made in public places and shared via social media. Someone might thus inadvertently on websites like Facebook may end up and be "tagged". In order to prevent this, the eyeglasses of a reflective material is provided. If someone has a picture with a flash makes the light is reflected and dazzles the camera, making the face of the wearer is not visible.

In the event no flash is used has the glasses on infrared light. That disturbs the sensor of the camera. "If you're worried about your privacy and want to be invisible, then you can ever buy this privacy glasses in the future," said Tony Anscombe AVG.Whether the virus fighter plans to bring the glasses on the market is not yet known.
