Abstract
This paper presents an effective self-embedding pixel wise fragile watermarking scheme for image content authentication along with tampered region localization capability. In this approach the watermark is generated from the five most significant bits (MSBs) of each pixel using three different algorithms and embedded into the three least significant bits (LSBs) of the corresponding pixel in the host image. At the receiver side by comparing the recalculated and extracted LSBs, one can easily identify the tampered pixels of the watermarked image. Results of experiments demonstrate that the proposed scheme has very high fragility and fidelity.KeywordsFragile WatermarkingTamper DetectionSelf-embedding
