Elliptic Curve Cryptosystem Combination Image Hiding Of Business Documents Secure Transmission

RSA is always the most popular encryption algorithms to change the information into cipher text before hiding data in images. RSA must rise its key length to keep security ability as CPU may process faster enough to break it. At the same time, there must be limit rooms to save cipher text when hiding data in image. This is a contradiction to save a gradually longer key in a limit room. We proposed a solution to combine the Elliptic Curve Cryptosystem and Digital-Image-Hiding, the advantage of ECC's shorter key at the same security level will solve the problem in some extent, at the same time make the transfer of document secure and also cryptic. After analyzed its security performance and market advantages, we implemented a suit of software combined with ECC and picture-hiding, it has such advantages as safe, efficient and useable, which can provide secure transfer for e-document or private information on Internet.
