Abstract: We consider a method for preventing e-Fraud in which an image is encrypted using a floating point cipher and then output is generated in image cipher text. To hide the encrypted information, the output is ‘embedded' in a host image. In principle, any cipher generator can be used for this purpose and the method has been designed to operate with images. The approach has a variety of applications and in this paper, we focus on the authentication and self-authentication of edocuments (letters and certificates, for example) that are communicated over the Internet and are thereby vulnerable to e-Fraud (e.g. modification, editing, counterfeiting etc.).
