Image Encryption and Decryption Using SCAN Methodology

This paper proposed an image encryption and decryption process. Its encryption method is based on SCAN patterns generated by the SCAN methodology. The SCAN is a language-based two-dimensional spatial-accessing methodology which can efficiently specify and generate a wide range of scanning paths. Then scanning paths sequence fill in original image. Note that the scanning paths with random code generating procedure, which produces the encryption keys in a very many ways; so come to the quite secret system. This paper presents a brief overview of SCAN, encryption and decryption algorithms, and test results of the methodology
