Abstract: Securing the Data over the wireless transmissions is the urgent need in the Data Communication field. The Protection of information over the wireless networks by encrypts the information but due to advancements in the computing techniques the cipher texts can easily detected and decrypted. So avoiding the attacks from the unintended users the presence of secret information must masked. It helps the recipient to protect the message from the hackers. In this regard a technique is developed to hide the Secret information over the wireless networks a cover digital image is used and that is called digital Image steganography. Digital Image Steganography is hiding data within image more securely and confidentially for the communication. This paper emphasis the Hardware based digital image Steganography using blackfin BF532 ADSP processor.

Keywords: steganography, blackfin, secure communication.
