JPEG Steganography based on uniform embedding and Syndrome trellis codes

Aasemuddin Quazi, A K Gulve
Steganography is the art and science of concealed communication with an intention to hide the secret messages in the cover medium. The Uniform embedding distortion is used along with the syndrome trellis codes to minimize the distortion. Syndrome codes give near-best rate distortion function. Here SHA 256 hash function is used to improve the security of the image. Thus, statistical detectability will be reduced thereby improving the security.
