Different LFSR arrangements using different connection unit have been implemented at the hardware level for hiding/extracting the secret data. The LFSRs are utilized in this approach as address generators. between the idea from the random pixel manipulation methods and the Least Significant Bit (LSB) matching of Steganography embedding and extracting method.In a proposed steganography hardware approach, Linear Feedback Shift Register (LFSR) method has been used in stego architecture to hide the information in the image. The proposed algorithm is based on merge. This paper presents an implementation of color image steganographic system on Field Programmable Gate Array and the information hiding/extracting techniques in various images. The cover carriers can be image, video, sound or text data. Steganography is the idea of hiding secret message in multimedia cover which will be transmitted through the Internet.
