Efficient Searching Of Cloud Data Using Multi-String Matching

Abstract

The cloud contains large volume of data that are stored by the cloud data owners. These cloud data will be encrypted by using the Symmetric Encryption Algorithm for data confidentiality. This makes searching of the documents/data difficult. Thus the efficient multi string matching algorithm called the Aho-Corasick algorithm is used. This algorithm gets the search text as the input keyword and provides the output file by matching it with the predefined keyword. This algorithm is used to find all occurrences of set of patterns given in the text string. The Aho-Corasick algorithm has the wide application over the text and pattern mining whereas the existing system uses the fuzzy keyword search.
