Additionally, smudges or scratches on the screen or fingerprint sensor could make it easier for unauthorized access to your smartphone.

Another security concern with in-display fingerprint technology is the potential for hacking. As with any technology that stores personal information, there is always a risk of hackers gaining access to your data. In the case of in-display fingerprint technology, hackers could potentially intercept the data being transmitted between the sensor and the phone’s processor. This could lead to sensitive information, such as banking details or personal messages, being compromised.

False acceptance rate and false rejection rate: Explained

Another consideration for in-display fingerprint technology is the false acceptance rate (FAR) and false rejection rate (FRR). In simple terms, the FAR is the percentage of times the system accepts an incorrect fingerprint as the correct one, while the FRR is the percentage of times the system rejects a correct fingerprint as incorrect. These rates can impact both the user experience and the overall security of the smartphone.

One way to reduce the FAR and FRR is to improve the quality of the fingerprint sensor. This can be achieved by using more advanced technology, such as ultrasonic sensors, which can capture a more detailed image of the fingerprint. Additionally, software updates can also improve the accuracy of the system by refining the algorithms used to match the fingerprint with the stored data.

It is important to note that the FAR and FRR can also be affected by external factors, such as dirt or moisture on the user’s finger. To mitigate this, some smartphones have implemented features such as automatic cleaning of the sensor or requiring the user to wipe their finger before scanning.
