Abstract :
A cryptographic protocol is proposed to address a problem of data integrity, namely the certification of digital images so that they can be regarded as evidence for legal purposes. The protocol uses public key techniques and works by chaining together images from different sources in a digital signature scheme. It protects against manipulation of images either by a single party or by collaboration between one party and the certifying authority
