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.
