Abstract:
The provenance is a complementary data documentation. It contains a description of "how", "when", "where", "why" the data were obtained and "who" obtained it. The provenance includes not only the origin of the data but also the description of the processes that produces it. Data provenance might be very helpful in image processing to reproduce images, save disk space, increase speed transmission, protect the copyright and retrieve images. In our work, we have developed a Web processing system that capture and manage image provenance. This systems is integrated with the URLib digital library. Some preliminary tests have shown the feasibility and efficiency of the proposed data provenance management system.
