In this work, we introduce a new algorithm to solve the problem of rightful ownership of digital images. Our algorithm solves the problem of multiple claims of ownership. This algorithm enables the legal owner to prove his ownership of the digital image even when an attacker embeds an un-legal watermark in this image. The algorithm introduces here satisfies all the mandatory requirements for any successful watermarking algorithm. Digital colored images were used, several sample images and watermarks were examined and performance evaluation metrics were exercised to validate the success of the algorithm.
