An Image Encryption Algorithm Based on Josephus Traversing and Position Disordering

摘要

This paper mainly studies the scrambling technology of digital image; discussing the image hashing algorithm based on Joseph Traverse. This paper explains the image encryption process based on Josephus, and use Matlab to encrypt different pictures and screenshot. At the same time, analyzed the Key sensitivity and Correlation algorithm, and judge the effect of encryption algorithm by compare original image with each encrypt image.
