Analysis of Reliability in Web Services for Fuzzy Keyword Search in Encrypted Data

摘要

As Web services become more prevalent, more and more sensitive information are being centralized in the web. Usually lots of sensitive information is stored in the web. To provide data privacy data has to be encrypted before outsourcing. Traditional searchable schemes also allow a user to search the encrypt ed data securely in the web through keywords and retrieve files of interest , but these techniques only allows exact keyword search. They don't retrieve the files which are having minor differences or inconsistencies in the keyword positions.This significant drawback makes existing techniques unsuitable in Web service as it greatly affects system usability, and making the user searching frustrat ing and less efficient.Fuzzy keyword search makes user search easy by returning the closest possible matching files based on keyword similarity semantics, when exact match fails. Reliability of web services for the application is analysed and opt imized by implementing efficient algorithms and techniques
