MSPPIR:云计算中多源隐私保护图像检索

MSPPIR: Multi-source privacy-preserving image retrieval in cloud computing

Qi Gu, Zhihua Xia, Xingming Sun

摘要:

基于内容的图像检索(CBIR)技术已经得到了广泛的研究,并在云计算的帮助下,如谷歌图像服务。然而,图像中往往包含着丰富的敏感信息。在这种情况下,由于云总是不能被完全信任,因此隐私保护成为一个大问题。许多隐私保护的图像检索方案已经被提出,其中图像所有者可以将加密的图像上传到云端,所有者自己或授权用户可以在云端的帮助下执行安全的检索。然而,现有的研究很少注意到多源场景,这是更实际的。本文分析了多源隐私保护图像检索(MSPPIR)的难点。然后以JPEG格式的图像为例,提出了一种JES-MSIR方案,即一种新的JPEG图像加密方案,它是为多源基于内容的图像检索而设计的。JES-MSIR可以支持MSPPIR的要求,包括多源的恒定轮安全检索和多源的联合以提供更好的检索服务。实验结果和安全性分析表明了该方案的有效性、安全性和准确性。

英文摘要:

Content-Based Image Retrieval (CBIR) techniques have been widely researched and in service with the help of cloud computing like Google Images. However, the images always contain rich sensitive information. In this case, the privacy protection become a big problem as the cloud always can't be fully trusted. Many privacy-preserving image retrieval schemes have been proposed, in which the image owner can upload the encrypted images to the cloud, and the owner himself or the authorized user can execute the secure retrieval with the help of cloud. Nevertheless, few existing researches notice the multi-source scene which is more practical. In this paper, we analyze the difficulties in Multi-Source Privacy-Preserving Image Retrieval (MSPPIR). Then we use the image in JPEG-format as the example, to propose a scheme called JES-MSIR, namely a novel JPEG image Encryption Scheme which is made for Multi-Source content-based Image Retrieval. JES-MSIR can support the requirements of MSPPIR, including the constant-rounds secure retrieval from multiple sources and the union of multiple sources for better retrieval services. Experiment results and security analysis on the proposed scheme show its efficiency, security and accuracy.
