Content security requires authenticity given by integrity checks, authentication and non-repudiation. This can be achieved by using digital signatures. This paper presents a new semi-fragile steganographic technique for embedding digital signatures in images. This is achieved by using a novel modified Bit-Plane Complexity Segmentation (BPCS) Based Steganography scheme. Semi-fragile implies survival from limited processing, which is achieved by utilising Convolutional coding, a Forward Error Correcting (FEC) channel coding technique, in the embedding.
