DIGITAL COLOR IMAGE ENCRYPTION BASED ON INVERTIBLE MATRIX WITH SECRET SHARING

This paper explores the new approach to implement image encryption in digital color images. The self invertible matrix created from the original image is used as keys for the RGB to YCbCr transform and the secret sharing operations. The encryption process carried out by the four steps: pixel permutation, creating RGB matrix, RGB to YCbCr transform and the secret sharing. The quality of the encrypted images are tested with visual inspection and evaluated with different quality measures. The performance of the proposed method is also evaluated by various testing methods.
