Image encryption using P-Fibonacci transform and decomposition
TL;DR: A new image encryption algorithm is introduced by using a combination of parametric bit-planes decomposition along with bit-plane shuffling and resizing, pixel scrambling and data mapping, which can be used to encrypt images, biometrics and videos.
