摘要

A cheque truncation system (CTS) is used for the faster clearing of cheque. CTS of bank sends electronic cheque images to drawee branch for payment through the clearing house. It is normally believed that the system is safe and secure. However, the intruders may damage the data and can degrade the quality of cheque image or can duplicate cheque image. There is necessity of security and copyright protection. By using combined Discrete Wavelet Transform (DWT) and Discrete Cosine Transform (DCT). It is implemented imperceptibility of watermark which are supported for copyright protection and security for the cheque images..
