Challenging the Security of CBIR Systems

چکیده
Content-Based Image Retrieval Systems are now commonly used as a ltering mechanism against the piracy of multimedia contents. Many publications in the last few years have proposed very robust schemes where pirated contents are detected despite severe modi cations. But none of these systems have addressed the piracy problem from a security perspective. It is now time to check whether they are secure: Can pirates mount violent attacks against CBIRS by carefully studying the technology they use? This paper analyzes the security aws of the typical technology blocks used in state-of-the-art CBIRS and shows it is possible to delude systems, making them useless in practice.

Depuis quelques années, de nombreuses travaux ont proposé des systèmes de reconnaissance très robustes où ces contenus piratés, même sévèrement modiés, peuvent être détectés. Néanmoins, aucun système n'a envisagé ce problème de piratage du point de vue de la sécurité. Il est temps de le faire : est-ce que les pirates peuvent mettre au point des attaques violentes contre ces systèmes après avoir nement étudié les moindres détails des technologies qu'ils emploient? Cet article analyse les failles de sécurité des briques technologiques typiques utilisées dans les systèmes de reconnaissance de l'état de l'art et montre qu'il est alors possible de les tromper, les rendant inutiles en pratique.

In this study, a new model is proposed to solve the problem of transmission and battery expansion planning considering integrated electricity and gas systems. The presented model is a bi-level stochastic planning model, where transmission and battery expansion planning modeling is done on one level, and gas network modeling is done on the other level. Here, the impact of the high penetration of...
متن کاملSecure Image Retrieval Based on Visual Content and Watermarking Protocol
As an interesting application on cloud computing, content-based image retrieval (CBIR) has attracted a lot of attention, but the focus of previous research work was mainly on improving the retrieval performance rather than addressing security issues such as copyrights and user privacy. With an increase of security attacks in the computer networks, these security issues become critical for CBIR ...

Abstract: Voltage instability is a major threat for security of power systems. Preserving voltage security margin at a certain limit is a vital requirement for today’s power systems. Assessment of voltage security margin is a challenging task demanding sophisticated indices. In this paper, for the purpose of on line voltage security assessment a new index based on the correlation characteristic...
متن کاملA Efficient Content based Image Retrieval System using GMM and Relevance Feedback
Content-Based Image Retrieval (CBIR) systems are required to effectively extract information from ubiquitous image collections. Retrieving images from a large and highly varied image data set based on their visual contents is extremely challenging. CBIR has been studied for decades and many good approaches have been proposed. But they do have some drawbacks. Texture and color are the significan...
متن کاملContent Based Image Retrieval Using Signature Representation
Retrieving relevant images from a large, diversified collection using visual queries (image content) as search argument is a challenging and important open problem. It requires an efficient and effective content-based image retrieval (CBIR) system. Image representation has a profound effect on the performance of CBIR. This paper presents a CBIR system based on a novel image representation using...
