SECURING THE RECORDS OF LEGAL COMPLAINTS USING MULTI AUTHORITY ATTRIBUTE BASED ENCRYPTION

Abstract

  Legal  complaint   records   are   sensitive and  may be  stored  in   a separate database in encrypted form. However, normal encryption of these records will eliminate data utility because searching the encrypted files is tedious. Uploading may cause a range of privacy issues due to the danger of data leakage. Authorizing various officials to look and access records originating from multiple  complaints in  a  very secure  and  scalable  manner could be a nontrivial matter. To handle these issues, we propose a certified searchable encryption scheme under a multi-authority setting. Specifically, our proposed scheme enables each authority to limit the search capability of various officials supporting the severity of complaint. The proposed system is made on a dynamic database, and all authorities can encrypt sensitive data offline and so send the new entries to the server. The server renews the encrypted database for the new entries. To boost security, we utilize multi-authority attribute based encryption to permit the authorization process to be performed just once by forward privacy to multiple authorities. Forward security could be a property of dynamic searchable schemes for encrypted databases because it can diminish file injection attack by ensuring that newly updated items can't be associated with previous search results. Analysis has proved that our proposed scheme introduces less overhead when compared with existing encryption schemes.
