- W3144025983 abstract "Nowadays, digital watermarking techniques are used to protect the integrity and authenticity of digital image and to provide capabilities for self-recovery of tampered locations. In this paper, a blind watermarking technique for image authentication and recovery of tampered area is proposed. Here the watermarking is done in block-wise manner by dividing the original image into non-overlapping blocks of 4*4 sizes. Here watermark data is consisting of authentication data and recovery data. Authentication data for each block is embedded in same block and recovery data is embedded in mapped block. Watermark data is generated using self-embedding techniques. This proposed scheme is checked against different types of attacks and different percentages of content modification of original image. The experimental results represent accurate detection and localization of tamper and high-quality recovery." @default.
