I want to create a picture based password system, wherein the user clicks on certain positions in an image, and then that is verified..
Can anyone help me out..how to store these pixel locations. Since the size is small, i want to store them in an array using SharedPreferences and then extract it from there to verify it.
I tried saving it but when i access the file..i only get the last pixel stored. I need to compare 5 pixels positions that were clicked on.
Also will it be secure if the pixel positions are stored as it is in the internal storage...it needs to be encrypted right? Then how do we decode it and compare?
