摘要For developing a safety network transmission environment, there are many cryptography methods that can be used to protect the intellectual property rights and the secret data, but the time complexity of encryption and decryption processes are very long. And the encrypted message becomes noise-like data that is easy to be suspected. For solving these disadvantages, we use data hiding techniques, and hide a secret image into two meaningful images. Meaningful shares may make people not to suspect that some secret data are existed in these shares. Hence it will create a safe secret communication channel. In this paper, we present a scheme which can be used to share a true color secret image into two meaningful cover images. We utilize random number generator and XOR operation to make cover images look innocent and do not show any clue about the secret image. Because of the usage of the random number and secret key, even if one share has been stolen by unauthorized persons, it is still hard to be decrypted to reveal the secret image.
