Image authentication has become an emergency issue in the digital world as it can be easily
tampered with the image editing techniques. In this paper, a novel robust hashing method …

A novel two-phase robust content-based image authentication scheme is introduced. The
proposed scheme is constructed based on a combination of hard and soft authentication …

Much previous work in video fingerprinting has focused on robustness and security issues,
but the compactness requirement, ie, the hash should be of a short length with acceptable …

感知哈希(Perceptual Hashing) 是多媒体数据集到摘要集的单向映射, 为多媒体数字内容的标识,
检索, 认证等应用提供了安全可靠的技术支撑. 本文提出一种融合视觉感知及时空域特征的视频 …

In order to defend neural networks against malicious attacks, recent approaches propose
the use of secret keys in the training or inference pipelines of learning systems. While this …

In this paper, we study adaptive evaluation techniques for querying XML-based electronic
catalogs, and show, by means of experiments performed on real-world catalogs, that our …

This paper proposes a new architecture for the secure application of robust perceptual
hashing. Protocols based on architecture of four parties are designed to ensure that no party …

This paper evaluates the security of a recently proposed perceptual image hashing scheme
based on virtual watermark detection. Under the known-hash attack where the attacker has …

Due to the advances in wireless networking and mobile computing techniques, multimedia
data are often distributed through unreliable wireless channels where packet losses or …

The discrete-binary conversion stage, which plays the role of converting quantized hash
vectors into binary hash strings by encoding, is one of the most important parts of …
