A novel data hiding algorithm for all types of file based on Injection process

Data hiding technique is qualified as one of the most important scientific fields in computer science. Steganography is a powerfull technique that hide a data and make it in a secure manner and avoid any curious person from attacking it. In this paper, we proposed a novel data hiding technique for any type of files, in which we can hide any file in another file by using the Injection process. This technique has two stages: Encoding in the sender point, Decoding in the reciever point. The injection process doesnt affect on the pixels or the signals of the two files (visible, invisible). After inject the file in another file, the result file will be encrypted and in the reciever side it will decrypted. So this algorithm mix the watermarking technique with encryption technique. The performance of this algorithm is very good comparing with another algorithms, and also the performance of data doesnt affected by the injection process.
