Security Analysis on Privacy Data Encryption in Many Order Using Magic Number

Abstract

Order Preserving encryption (OPE) is efficient tools to encrypt relevance score of an inverted index. In this one to many orders preserving encryption is proposed which will encrypt the single plaintext into many cipher text data. For a customer to get access to this data the encrypt data will be provided with a relevance score which is nothing but relevant information of that user. Based on that relevant score an inverted index is created. The inverted index contains the private key of the particular user and that user’s information. This method are used to get the information from the cloud with more secure. These information are grouped in clusters for easy access by the users.
