Detecting Re-projected Videohigh quality, it is usually easy to visually detect such recordings. However, given the wide variety of video content and film-making styles, automatic detection is less straight-forward. We describe an automatic technique for detecting a video that was recorded from a screen. We show that the inter

Residual Information of Redacted Images Hidden in the Compression Artifactsensitive region with black or white values. Our goal is to study the effectiveness of this simple method in purging information. Since digital images are usually lossily compressed via quantization in the frequency domain, each pixel in the spatial domain will be “spread” to its surroundings, simila

Block-Chain Based Fragile Watermarking Scheme with Superior Localizationship between the security strength and block size is also discussed. In the proposed scheme, all blocks in the original image randomly form a linear chain based on the secret key in such a manner that the watermark of an image block is hidden in the next block in the block-chain. In the tamper detec
