Design and Implementation of Fuzzy Search for Encrypted Arabic Documents in Cloud Computing

Abstract

In the recent metamorphosis era, information technology has brought a dramatic change in computing world which has significantly impacted human convenience, entertainment, enjoyment, among others. Internet-based computing has provided high performance through reliability, scalability and flexibility at a lower cost. Every new technology emerging has been accompanied by few threats which are to be addressed before the situation gets worse and the technology is totally abandoned. Though cloud computing has many advantages, business people are still reluctant to take their confidential data over the cloud with the main reason being the security issue. In this dissertation, Arabic Fuzzy Search Scheme “AFSS” model has been proposed which is expected to ensure a tight security to the data stored at the cloud along with proper authentication of the users who want to access the cloud resources and services. In this dissertation, the main focus is to design a new efficient search algorithm that works over encrypted Arabic documents. Emphasis is placed on wildcard-based fuzzy set in the algorithm. The use of wildcards is based on an efficient algorithm as there is an increase in construction time in relation to the number of keywords. During this dissertation, solutions were proposed and implemented for an essential problem of management method will be applied to Arabic documents and keywords before they get outsourced security of sensitive information. The algorithm offers privacy that enables keyword search over encrypted Arabic documents. Real testing demonstrated that Arabic Fuzzy Search scheme is secure and effective data utilization for outsourcing cloud data. In conclusion, this dissertation formulated as well as solved problems in applying fuzzy search over encoded Arabic documents in a cloud platform for the first time and support effective and efficient use of cypher data stored remotely. The thesis also formulated and implemented Arabic fuzzy search sachem using wildcard technique in order to construct the fuzzy keywords. The proposed Arabic Fuzzy Search Scheme AFSS model is secure and has higher reliability to achieve the solution for remote sensitive Arabic documents. As a future perspective, it is recommended to continue applying research on security mechanisms which support and provide privacy preserving remote encrypted Arabic documents remote storage in cloud environment takes the responsibility of complexity of language and lack support Arabic research.
