The ambition to achieve covering of secret messages into another file is implemented in many steganographic solutions, but usually the message is covered only into one file. In this paper the mechanism based on the method of steganography, with use of many cover files, is described. Proposal of the algorithm, based on Last Significant Bit method of steganography, is also described. The main contribution of this work is in the proposal of multi-carrier steganographic solution along with its implementation in the software application.
