Abstract
In this paper a new digital fingerprinting scheme for images is proposed. A proposed method is based on quaternion encryption with Cipher Block Chaining (CBC) mode of operation. Quaternions are hyper-complex numbers of rank 4 and thus often applied to mechanics in three-dimensional space. The encryption algorithm is designed for grey-tone images. For purpose of encryption, the algorithm uses the rotation of data vectors presented as quaternions in a three-dimensional space around another quaternion (key). On the receiver’s side, a small amount of unnoticeable errors occurs in the decrypted images. These errors are used as receiver’s digital fingerprints for the purpose of traitor tracing in case of copyright violation. A computer-based simulation was created to scrutinize the potential of the proposed scheme. The obtained results are shown at the end of this paper.
