Resumen de Verification of authenticity of transmitted images
This paper proposes a new technique for the verification of authenticity of transmitted images through the Internet. The scheme works on the combination of the chaotic cat map for the scrambling the addresses of the pixels, the Hamming code for the encryption of pixel values and the digital signature for the verification of tampering. The digital signature of the original image is added to the encoded version of the original image to be transmitted. At the receiver end, comparison is performed between the embedded digital signature from the received image and computed digital signature from the received image to verify the authenticity of the image.
