Private Information Retrieval in the Cloud Using Blinded Correlations: An Idea
نویسنده
چکیده
Alice is a user. Clyde is a cloud service provider. Alice has a bunch of very large files containing many, many words. Alice wants to store the files in the cloud. Alice wants to do a particular form of private information retrieval (PIR); specifically: Alice wants to determine which file or files contain a given target word. Alice wants Clyde to do the necessary computations (or most of the computations) in the cloud. Alice assumes that Clyde is honest but curious: Clyde will faithfully perform any computation Alice tells him to do and will return the correct answer, but Clyde would like to learn the results for his own purposes. Alice, on the other hand, has the following goals:

متن کاملPRISM - Privacy-Preserving Search in MapReduce
We present PRISM, a privacy-preserving scheme for word search in cloud computing. In the face of a curious cloud provider, the main challenge is to design a scheme that achieves privacy while preserving the efficiency of cloud computing. Solutions from related research, like encrypted keyword search or Private Information Retrieval (PIR), fall short of meeting real-world cloud requirements and ...
