In today's world, technological security is paramount. I remember a time when we needed a pin code or a graphic key to protect a gadget. More precisely, we were not offered anything else. And some did not seek to use it. That's desperate. Today, our smartphone has almost all our lives - payment cards, private photos, and someone has a little bitcoin. And just recently, we were amazed and delighted by the fingerprint scanners, as manufacturers are already actively implementing Face Unlock ( Face ID ) - unlocking the device on the face.
For some it will be a revelation, but the first mention of the technology dates back to the 60s of last century. At the time, this was done by scientists, not engineers at smartphone factories. They tried to teach the computer to recognize a person's face. But, unfortunately, they did not succeed - they could not solve the problem of recognition in conditions of unstable lighting. At the end of the century, he still learned to distinguish between people and even & nbsp; obstacles such as beards, mustaches or glasses did not interfere with him. But the problem with light has not been solved. Because the technology was used only for security systems and digital cameras - everything worked quite satisfactorily. & Nbsp; We managed to get rid of this shortcoming thanks to stereo shooting - two cameras recognize the depth of the scene much better than increasing data accuracy several times.
It is worth noting that in a quality device and technology will work much more efficiently. Another story with the Chinese trying to save on everything. In principle, it is possible that your gadget will be able to unlock your twin sister or brother. But although nature creates the same people, the twins are still not 100% identical. So there is a small chance that you will still be able to hide what you want. Tip for paranoids - use an additional method of protection, such as a fingerprint or password. It's a pity that not all models have such a feature.
Most smartphones with this technology now use a front-facing camera. And it still doesn't work perfectly because it needs enough light. However, some manufacturers of budget devices take away the fingerprint scanner. So you can not expect a quick and reliable unlock. You can keep your secrets in such a smartphone only at your own risk.
Some people worry that cunning hackers will get data through face scanning technology. But experts say you should not worry. The face pattern is stored in a separate sector of the smartphone's memory. Most hackers will not get there. But if you know of any cases, feel free to share in the comments.
Among the undeniable advantages of Face Unlock (Face ID) is the ease of unlocking the device in winter, when your hands are cold even in gloves - just look at your smartphone. Well, and among the disadvantages of this method is that every time you look at the screen to find out the clock, it will be unlocked. But who is perfect in this world?
