A method of encoding and decoding secure message for transmission based on keyless rotational (carpet) shift algorithm with aborted objects of an image

摘要

A method of encoding of a secure message for transmission comprising the steps of : performing an encryption using keyless rotational (carpet) shift security algorithm to the the digitized input message for output encrypted ciphertext message; applying steganography to the said encrypted message using aborted objects of the original Image with embedded technique of Penultimate and Least Significant Bit (PLSB) for a resultant stego object; and watermarking of the resultant aborted stego objects.
