RESUMO

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 produce them (algorithms and their respective parameters). Data provenance might be very helpful in image processing to reproduce images, save disk space, increase speed transmission, protect the copyright and retrieve images. To take advantages of image provenance, must be managed by computer systems. Its management includes the creation, storage, publication, retrieval and handling of provenance in an automatic and integrated way. Motivated the advantages of provenance and the challenges of its management, the goal of our work was: to propose a model, a structure and storage of data provenance in order to guide its implementation; to implement a prototype for the data provenance management; and to test this prototype in image processing. This prototype was integrated with the URLib digital library. The preliminary tests have shown the feasibility and efficiency of the proposed data provenance management system.
