摘要：This paper presents a new technique for transmitting secret information securely from one party to another by embedding this information into a video after encryption through salt cryptography. We have tried to utilize the advantages of salt cryptography which has been ignored by data hiding community. In this encryption method some random data is added to the secret keys and passwords. We will define this random data as a salt which is needed to access the encrypted data, along with the password. Alone these passwords have no use since they will be able to locate the hidden data only when mixed with proper salt. This salt is managed by a certified third party. Different salt is created for different pairs of communicating parties. The purpose of salt is to add arbitrary random data to the string being hashed, such that you increase the length of input to hash. We have also introduced the concept of Enterprise Dependent Value (EDD), which are the embedding values corresponding to the binary digits and are specific to the communicating enterprises. The effectiveness of the techniques has been shown through experimental results. The performance of the proposed technique has been compared with the other techniques of watermarking, steganography and encryption.
