Abstract:
Th is paper presents a new w aterma rking schem e o f d ig ita l images based on the fea ture po ints. In th is schem e, the or ig ina lw aterm ark can be converted into two w aterm arks interrelated w ith dig ital im ag e and then be embedded into the circum jacent area of fea ture po ints through chaos sequence. W hen checking, two w aterm a rks are checked at the sam e tim e, and the or ig ina l wa term ark can be resum ed. Exper imenta l results and theo re tic ana lyses show that the schem e can stand aga inst severa l attacks, such as im ag e com pression, g eom etr ic attack, IBM a ttack, etc.
