Visual Cryptography Secret Share Creation Techniques with Multiple Image Encryption and Decryption Using Elliptic Curve Cryptography

Abstract

In Cryptography the covert image share creation method and multiple image encryption and decryption are used with different algorithms. In this work, Visual Cryptography (VC) is used for the outline of shares that have been generated from the novel image. Red, Green, and Blue pixel shares are one by one formed by the Visual Secret Sharing (VSS) Scheme. It proposed the ECC method for image encryption and decryption using Rubik’s cube image encryption algorithm. The encryption method is by a public key cryptography generator and the decryption method is done by the secret key arbitrarily generators of the ECC method. For humanizing, the performance analysis of Elliptic Curve Cryptography methods, such as the optimization techniques, was used for PSNR, MSE, and the Number of Pixel Changing Rate (NPCR) and (UACI). The outcome explains that the planned algorithm is improved over various other methods compared to the presented methods. The future technique is implemented with Matlab coding.
