Computer security has to re-invent itself. New technologies and new applications bring new threats. Especially with the increasing growth of data a communication cryptography and data security are an essential requirements for communication privacy. This paper present a new approach that combines between two technical partial cryptography and 2D wavelet transform. The process consists of two stages: First stage is to compress the image to reach LL2 and LL3. Second stage is to pass the resulting image after compression process to encryption process that uses image that has strong randomness used as a key. The result of this approach is good and helps in solving the problem of keeping image privacy.Key word: Image Compression, Wavelet, Random Key Generated, Partial Cryptography.
