Face ID: the next iPhone could be even more secure

-

No more masks to trick the iPhone, goodbye the risk of seeing a twin or a family member unlock his phone. Apple has patented a technology that greatly improves the security of its devices.

For Apple, the future of biometrics definitely seems to be moving away from our fingerprints. With the iPhone X, Tim Cook's teams have tipped the user into the world of facial recognition, supposed to be much safer and more difficult to circumvent.

Nevertheless, some facetious hackers managed to deceive the TrueDepth camera of the latest iPhone. Similarly, the iPhone X is in fact not always able to tell the difference between two identical twins.

Tomorrow, it may be more difficult to play Face ID, according to a patent, discovered by Apple Insider, filed by Apple in November 2015. The document describes a system that can detect the network of facial veins of the skin. the user with an infrared transmitter / receiver, like the one on the iPhone X.

How it works ? According to the patent, the transmitter transmits several pulses of infrared light to the face (or hand) of the person who wishes to authenticate. The infrared beam passes through the skin and reflects the veins of the user. This information is then sent back to the infrared sensor. A chip then generates a map of the blood vessels of the face. The tiny differences in delay in the return of light make it possible to build a 3D model of the face.

This system, which creates an in-depth authentication profile, greatly complicates the task of counterfeiters. It seems very difficult to reproduce the arrangement of the veins under the skin to successfully unlock an iPhone. The current Face ID system, with its false positive rate of one in a million, would still be safe. Indeed, if twins are similar to the naked eye, their blood vessels can not be perfectly identical.

It is obvious that this patent does not mean that Apple will apply this technology. Nevertheless, this system seems pretty close to what is already in place. We can hope that Cupertino engineers will succeed in integrating it into the next generation of iPhone.

We tested the Nuraphone, the headset that fits your hearing

-
Image
The Nuraphone is an innovative model both for its sound customization system and the design of its headphones. Is it enough to make a difference? How to offer the best possible sound for headphones? The Australian company Nura have tackled this thorny problem and have designed a revolutionary model: the Nuraphone, sold about 400 euros. This helmet is distinguished by its design that combines the circum-auricular and the intra-auricular. The inside of the earpiece has a tip that is placed at the entrance of the ear canal to transmit the sound more directly than with conventional supra or circumauricular models. According to the manufacturer, the tip penetrates less into the duct than the in-ear headphones, which explains the unique size. We would have liked the choice between several sizes and people who do not like the headphones may not like this model either. Another potential problem often related to ear-phones, the restitution of the bass. To avoid this problem, Nura ...

They turned Amazon Echo into an audio snitch

-
Image
Hackers have managed to create, in the smart enclosure, a seemingly innocuous application that continuously records conversations. With a microphone, smart speakers sometimes cause discomfort in some users who wonder if they do not record their words constantly. Checkmarx's hackers have just given some grit to this conspiracy theory as part of Amazon Echo. They developed a calculator in the form of a "skill", that is to say a voice application that extends the functionality of Amazon Echo. Just say "start calculator" to access and make calculations. Until then nothing abnormal. The problem is that the application continues to record the words of the user even if they are unrelated to the application. The speeches are then transformed into text and sent to the developer of the skill. To achieve this, hackers used a flaw in Amazon Echo's programming interface settings. Normally, a skill is supposed to turn off automatically after a certain time, when...

Dolby Digital, Atmos or DTS ... what do these audio technologies hide?

-

With the multiplication of audio formats, not easy to navigate to make the right choice. 01net.com explains the main ones to make sure you do not go wrong. Be immersed in a match and live the same atmosphere as the stadium? This is certainly what every football lover dreams about in front of his television. If the image participates more and more, including the broadcast of some matches in 4K, the audio is still the poor relation of sports retransmissions. However, we do not buy a TV only to watch football (well, normally). It is therefore good to know what the different formats used for cinema sound mean. Not always easy to cope with the acronyms and logos displayed on the data sheets of the devices or on the pockets of DVDs and Blu-ray discs. These are the latter that will usually give you the most systematic access to multichannel audio formats, with several voices in the front, rear and a subwoofer. Netflix also offers some compatible content, both movies and series. Two...
