Many image authentication methods have been proposed over the last decade; however, most methods provided only to focus single purpose This paper presents a multipurpose image authentication scheme based on vector quantization (VQ), and combined functions with copyright protection, integrity verification, and distinguishes between malicious and non-malicious attack simultaneously The authentication information is calculated from the VQ index tables of an original image and a lower bound image, and if the image has suffered attack, the correlation coefficient is adopted to find the location of the tampering The experimental results show that this scheme clearly distinguishes non-malicious manipulation from others, verifies ownership and locates the regions that have been tampered with
