Abstract EN
A novel approach to RGB channel based steganography technique is proposed.
The RSA algorithm is used for encryption and decryption.
In an RGB image, each pixel (24 bits) is having R-channel 8 bits, G-channel 8 bits and B-channel 8 bits.
The image is divided into 8 blocks and the cipher text is divided into 8 blocks.
One cipher block is allocated to be embedded in only one image block by a user defined sub key.
Out of the three channels in each pixel of the image one is used as the indicator channel.
The indicator channel for the different blocks is not the same.
The other two channels (called data channels) are used for hiding cipher text bits in 4 least significant bit (LSB) locations.
In a data channel 4 bits of cipher text can be embedded, if after embedding the change in pixel value isles than or equal-to 7.
The two LSBs of indicator will tell whether the cipher text is embedded in only one data channel or in both data channels, so that retrieving can be done accordingly at the receiver.
The Technique is implemented and results are analyzed.
