With the character of low maintenance, cloud computing provides an economical and efficient solution for sharing group resource among cloud users. Unfortunately, sharing data in a multi-owner manner while preserving data and identity privacy from an untrusted cloud is still a challenging issue, due to the frequent change of the membership. In this paper, we(More)
As the image data produced by individuals and enterprises is rapidly increasing, Scalar Invariant Feature Transform (SIFT), as a local feature detection algorithm, has been heavily employed in various areas, including object recognition, robotic mapping, etc. In this context, there is a growing need to outsource such image computation with high complexity(More)
Searchable symmetric encryption (SSE) allows a client to encrypt his data in such a manner that the data can be efficiently searched. SSE has practical application in cloud storage, where a client outsources his encrypted data to a cloud server while maintaining the searchable ability over his data. Most of the current SSE schemes assume that the cloud(More)
UNLABELLED Rosai-Dorfman disease (RDD) involving the cardiovascular system is extremely rare; to our knowledge, there are only 9 cases in the literature. Here, a case of a 60-year-old male with RDD involving the right atrium is presented. A comprehensive literature review was undertaken to summarize the clinical and pathologic features of this disorder. (More)
The image and multimedia data produced by individuals and enterprises is increasing every day. Motivated by the advances in cloud computing, there is a growing need to outsource such computational intensive image feature detection tasks to cloud for its economic computing resources and on-demand ubiquitous access. However, the concerns over the effective(More)
In this paper, we present SecSIFT, a high-performance cloud based image feature detection system for performing Scalar Invariant Feature Transform (SIFT) over private image data without compromising the privacy. In contrast to previous works, we outsource the computation of image feature detection to a set of independent, co-operative cloud servers, and(More)
