TCBR and TCBD: Evaluation metrics for tamper coincidence problem in fragile image watermarking
Engineering Science and Technology, an International JournalThis paper proposed two evaluation metrics of the tamper coincidence in a block map design for image watermarking. These evaluation metrics are called Tamper Coincidence Block Ratio (TCBR) and Tamper Coincidence Block Density (TCBD). A tamper coincidence

A Triple Self-Embedding Fragile Watermarking Scheme for Image Tamper Detection and Recovery [PDF]
IEEE AccessThis paper presents a new triple self-embedding fragile watermarking technique for image tamper detection and recovery. This approach divides the host image into non-overlapping regions according to the block map and further divides each region into $5 ...

A Self-Recovery Fragile Image Watermarking with Variable Watermark Capacity
Applied Sciences, 2018 Currently, the watermark capacity of most self-recovery fragile image watermarking schemes is fixed. That means for smooth regions and texture regions, the length of watermark information is always the same. However, it is impractical since more recovery

Region‐based scalable self‐recovery for salient‐object images
ETRI Journal, 2020 Self‐recovery is a tamper‐detection and image recovery methods based on data hiding. It generates two types of data and embeds them into the original image: authentication data for tamper detection and reference data for image recovery.
