Description
The concept of “blink comparison” method is simple - the app allows you to quickly switch pictures without delay so you can see the differences.
“Blink comparison” (Wikipedia) method uses high efficiency pattern recognition by human eyes, to permit quick verification between a reference picture and an actual one being taken on the spot. For example, in the goal of detecting tampering in high contrast nail polish tamper-evident seals.
Relative documentation on the tamper-evident glitter nail polish seals concept and why it is hard to beat:
Use, see, change and share; with all.

🔒 Security
Optionally, during initial setup (or at any time), you can enable encryption of reference images so that they are stored in encrypted form, making them difficult to steal or replace. Currently, password-based encryption (PBE) is used. It’s based on the XChaCha20Poly1305 scheme and using a key derived by Argon2 function “on the fly” (during the encryption/decryption itself). The password is stored in the app as a hash obtained with Argon2.
