ppt on an efficient privacy preserving ranked keyword search method computer science

Abstract

This article is a circuit that discusses safe search rank based on the keywords in an encrypted cloud data. Data to be transmitted is encrypted using a symmetric encryption algorithm for data confidentiality. The index file from a set of keywords, which can be found on the basis of outsourcing to the local server on which the trusted set of keywords, which is generated from the data files are also saved. In contrast to the architecture proposed in the previous works, where the index is stored in encrypted untrusted server, in our scheme index is stored in a local trusted server current time to reduce the transmission and processing costs. This is to ensure that untrusted server can not identify the data generated by an index. The index is created using Aho-Corasick matching algorithm with a few lines, which corresponds to a predefined set of keywords with the information in the data files for indexing them and store relevant data in the B + tree. Whenever a user searches for a keyword query is sent to a local server and a trusted indexed data is called. The files are extracted and ranked on the basis of certain criteria of relevance. Parameters required for ranking obtained from the data stored during indexing.
