Galaxy S8: What is the Basic Principle of Iris Scanning?

Last Update Date : Apr 23. 2018

The iris recognition feature uses the unique characteristics of your irises, such as their shape and pattern, to strengthen the security of your device.


Your iris data can be used for various authentication purposes.


After registering your irises, you can set the device to use your irises for features such as Screen lock, Web sign-in, Verifying your Samsung account, Secure Folder, and Samsung Pay.


Iris Registration

 1. Capture the iris (with IR Camera)

 2. Extract pattern of your irises and convert to digital form


Iris authentication

1. Capture iris for authentication

2. Extract iris pattern and digitize

3. Compare it with registered one and authenticate




• If you use your iris as a screen lock method, your irises cannot be used to unlock the screen when the device is turned on after shutting down. To use the device, you must unlock the screen using a pattern, PIN, or password you set when registering the irises.


Please ensure that you remember your pattern, PIN, or password after registration.


• If your irises are not recognized, you can unlock the device using the pattern, PIN, or password you set when registering the irises, and register your irises again.


If you forget your pattern, PIN, or password, you will not be able to use the device unless you reset it.


Samsung is not responsible for any data loss or inconvenience caused by forgotten unlock codes.
