A Secure Digital Watermarking Technique Using Multiple Transforms and Advanced Encryption Standard Technique used for Security of Bank Cheque Image

E-Commerce is related with worldwide web. Worldwide web and E-Commerce is a collection of customers & service providers. E-Commerce transfers data with the help of electronic data interchange (EDI).The secure e-transactions of are carried out by using master cards, visa cards, and online payments between customer, merchants, and bank system through EDI at minimum extra charge. The payments made through bank cheque don’t apply any charge to customer. The bank cheques are cleared with the help of cheque truncation system. It passes and clears the cheque image from home bank branch to clearing house of cheque bank branch through digital communication channel. During this transmission process, there may be intruders who are always watching the flow of data passing through channel. This may create issue of security & copyright protection for bank cheque image. To solve this problem there are two techniques i.e. digital watermarking technique to provide copyright protection service and advanced encryption standard technique for facilitating security service. In this research work combination of DWT-DCT-SVD transforms are used for digital bank cheque image watermarking and 256 bit key AES technique is used for encryption & decryption of digital watermarked bank cheque image.
