摘要：
In recent trends, information security is becoming more important in data storage and transmission. Therefore, the protection of information from unauthorized access is important. Image encryption plays a significant role in the field of information security. Several security Algorithms are existing for safer transmission of data. In this paper a new encryption method is developed and a comparison is done by transforming images using DCT, DWT and DCT with DWT. Various parameters are analyzed for comparison of encrypting levels.
