Verifiability is essential for a secret sharing approach which allows the involved participants to detect cheaters during the secret retrieval process. In this article, we propose a verifiable secret image sharing scheme that can not only resist dishonest participants but can also satisfy the requirements of loss less and camouflage. The new approach conceals the shadows into a pixel pair of the host...
Fragile watermarking is applied to protect the integrity of the digital media. Current fragile watermarking schemes mainly provide the functionality of detecting and locating the tampered regions of an authorized image. The capability to recover the tampered regions has rarely been discussed in the literature. In fact, the recovery ability is an important issue while proving and maintaining the image...
The significant essential of secret image sharing approaches is that the revealed content of the secret image must be lossless. Moreover, the distorted stego images can be reverted to the original cover image. In order to achieve these purposes, we first transform the secret pixels into the m-ary notational system. Then, the information data used to reconstruct original pixels from camouflaged pixels...
This paper presents a novel dual watermarking mechanism for digital media that embeds a recognizable pattern into the spatial domain and an invisible logo into the frequency domain. Undoubtedly, visible watermarking is important for protecting online resources from unauthorized reproduction. Due to the visibility of embedded patterns, however, watermarked digital media are vulnerable to the inpainting...
