Image Hiding Algorithm Based on Secure Steganography Mechanism
With the development of computer network,security awareness increases.Therefore,information hiding technology has been played an important role in security protection.However,most information hiding algorithms dont do well in security.In this paper,we propose the image information hiding algorithm based on SVD(Singularly Valuable Decomposition),which applies the singular value decomposition technique to the information hiding process module.And double barriers protect the security of information transmission.In the first barrier,the preprocessing module is added for information to be hidden.Its main function is to encrypt and compress information to be hidden into ciphertext so as to increase the amount of information embedded and to enhance its security.In the second barrier,the optimal embedding position in the carrier image is found by SVD decomposition technique before the ciphertext is embedded in the optimal embedding position.The concealment of information hiding is improved because of the above operation.The experimental results show that the algorithm achieves the purpose of improving the security of secret information transmission and the embedding amount.
