Framework of Trustworthy Digital Photo Management System

Abstract

This paper describes technologies and framework for assuring the origin and integrity of photographs used in enterprise's business applications. The proposed framework is a combined process of cryptographic key management and a watermark technology, creating a secure end-to-end photo transaction. The solution involves digital camera manufacturers who supply asymmetric (public) keys for the cameras, the originators of the photographs, who take the pictures, and the enterprise application systems for the photographs, which generate and transmit encrypted symmetric keys to control the verification process assuring the integrity of the photographs. We use an automobile insurance claim process as a pilot application model to discuss the proposed framework, and implementation.
