A Robust and Lossless Information Embedding in Image Based on DCT and Scrambling Algorithms

We have presented a new secure, lossless information embedding based on the DCT and scrambling algorithms to be use for the data embedding. Our algorithm can be used to embed the vital information such as, bank credit cards, social security numbers, and other secret information into a cover image and transfer it over internet or other network systems. Our algorithm applied three levels of securities to implement high securities procedures on the original data before they are transmitted on the internet or other network system. The three security levels are as follows: Level -1 to scramble original data, Level 2 to apply encryption based on the XOR operation of the scrambled data with the secret keys, and level 3 of security for hiding the scrambled, and encrypted data in to mid-frequencies of the cover image, DCT coefficients.
