This paper proposed a hash based steganographic approach in thermal images for authentication. Thermal images used in security measures for surveillance suffer from lack of authenticity. Thermal images are taken as cover images and bits from authenticating images/messages are inserted using a hash function. One, two and three bits per bytes are inserted into the cover images. The hash function increases the robustness of the technique and the adjustment optimized the image fidelity. Various… CONTINUE READING
