Original article: Samsung has chosen a unique sonic technology for the biometric scanners built under the screen in its leading devices - and now it turns out that a simple protective sticker is enough to break their reliability
Sometimes it seems that overly sophisticated technology in mass consumer products can lead to the opposite effect and cause insignificant headaches for the manufacturer of choice. Google experienced this with Its biometric face scanner raises eyebrows because of its ability to access the Pixel 4 devices even when the user closes their eyes, And now also סמסונג Experiencing something similar with the families modelGalaxy S10 andGalaxy Note its 10 now.
Samsung was the pioneer in using built-in fingerprint scanners under the screen based on Technology Supersonic, instead Technology Optically on all other devices on the market. Frequent radio waves were sent from the scanner to the finger clinging to it and returned back to the scanner depending on its physical structure, so that the user can be identified even in a situation where his hands are wet or dirty - which usually will not really work in common optical scanners.
The scanners on leading devices סמסונג, A joint development with a company Qualcomm, Have managed to prove themselves in practice in a completely not bad way - but now it turns out that they have a rather serious security flaw, which allows almost anyone to access the device in a situation where there is a silicone shield above the display panel. The same shield appears to create three-dimensional reflections that 'confuse' the advanced biometric sensors, causing the lock screen to open even when it comes to incorrect identification in fact.
This problem quickly went viral, prompting developers of various Android applications to announce the temporary fingerprint identification feature on devices Galaxy S10 andGalaxy Note 10 to minimize the potential for breach damage.
In Samsung itself Provided a formal notice In it they confirm the existence of the problem, and ensure its repair as soon as possible through a software update. And until that happens? The company advises users to stop using screen protectors, delete fingerprints stored in the system and save biometric details again, without the unruly cover - not really an effective solution for those who do not want to compromise on physical protection in a valuable device they have just purchased.
Samsung may well be able to overcome the strange bug in remote update in the near future (such an update seems to have begun a gradual distribution to devices in recent hours), but the negative impact of perceiving flagship devices from the company as unsure and unsecured would seem to be quite difficult to change. Now it remains to be wondered whether this saga will cause high-end fingerprint scanners to disappear from the market in the near future (or even permanently), or that Samsung will not give up this interesting technology so quickly.
updating: More information indicates that the security issue on devices סמסונג Created only when users purchased a new fingerprint for a system with an unrecognized and officially approved type of protective coating סמסונג - so that the information received in the sensor was for the refunds in the shield itself and not of the user's finger above it, so that the same refunds were there at any given time in fact and allowed the device to be opened each time. In the same way, removing the problematic protective cover over a locked device could lead to a situation where it is not possible to open the device by fingerprinting at all (although there is a physical password backup for such situations, as is well known).
Samsung has announced that it has started distributing its software update for the handsetsGalaxy S10 andGalaxy Note 10 which is supposed to prevent the rush, in the Korean market first and with planning for gradual global distribution in the near future (some consumers in Israel have already received it for their device, it seems) - but the company continues to clarify that they do not recommend unapproved and unapproved protective covers.
