Use pictures to unlock when locked by Face Recognition

Last Update date : Jul 22. 2022

Please note: This article is focusing on newer models such as Galaxy Note9, S9/S9+, Note8, S8/S8+ and A8/A8+

When using face recognition to unlock the device, your phone can be unlocked by someone or something that looks like your  image. Regarding the possibility of an exceptional case where the current detector can mistake fake image as a live input, the decision logic was already applied to strengthen the anti-spoofing function on the device.

However, due to usage of only a single frame from camera, there are technical limitations in coping with all spoofing attempts such as high-resolution images . Thus we do not recommend the usage of face recognition for high security authentication applications. And, as Face recognition is less secure than Pattern, Pin, or Password, we recommend to use the Iris recognition, Fingerprint recognition, Pattern, Pin, or Password to lock the device.

Thank you for your feedback!
