For many years, devices such as smartphones, tablets, and even laptops have used ultrasonic fingerprint readers, which not only offer the appropriate speed but also provide a good level of security. What if this level of security was increased by more than 2.5 billion times? Samsung has an idea for this.
Security of biometric data
It is not without reason that I mentioned the ultrasonic sensor in the introduction. Something that worked perfectly for years, went a bit into oblivion when readers began to be mounted under screens - the vast majority of manufacturers use optical readers in these cases, which are still very fast, but their level of security is definitely lower than in ultrasonic readers.
Yes, algorithms do what they can to protect against mistakes, but when it comes to security, it's never worth stopping and stopping on this issue. A similar opinion is shared by Samsung, which decided to approach the subject a bit differently than others.
As SamMobile notes, the South Korean manufacturer is in the process of developing technology to increase the security of biometric data based on fingerprints. Engineers want to make the entire OLED screen able to scan multiple fingerprints at once.
And even if it seems crazy and a bit unrealistic, it turns out that Samsung may have this technology ready to implement in its OLED panels in just a few years. According to ISORG, manufacturers could implement this new fingerprint security standard as early as 2025.
Samsung counts to three
The technological giant came to the conclusion that increasing the number of fingerprints read simultaneously can significantly increase the level of security. According to Samsung, the simultaneous use of three fingerprints for authentication is 2.5 billion times more secure than the use of only one fingerprint.

In addition to these obvious security-focused benefits, there is also one rather important practical aspect here. The new technology is supposed to work on the entire screen - no more aiming at a specific area of the screen under which the reader is hidden. On the other hand, it can also have a negative impact on practicality. Instead of quickly putting your thumb in the right place, you will need to use several fingers. For this you will need to engage both hands - one will hold the device, and the other will unlock.
As you can see, a lot will depend on how it is systemically resolved later. It is possible that unlocking with several fingerprints at the same time will be reserved only for the most sensitive data.

However, I must add that scanning more than one fingerprint at the same time is already offered by devices on the market. One of them is the Vivo X80 Pro, which was reviewed by Kasia in the summer - as you can see, Samsung did not come up with this idea first, but perhaps it will implement it in a better way. Who knows?
