Paper Abstract

This paper presents a watermarking system for images containing a single frontal facial region that is robust against rotation, scaling and translation attacks. The system presented can automatically detect the facial region within the host image, using an algorithm that does not rely on skin color information and is therefore insensitive to the variations of apparent skin color of the subject. The system then normalizes the rotation, scale and translation of the facial region. Therefore, the system is able to re-synchronize the watermark in the event of a rotation, scaling and translation attack. The experiments showed that the proposed system performed well under such attack. The system also showed good performance against common signal processing attacks such as filtering and JPEG compression.
