Encrypted graph based Keyword searching Technique

Abstract

In this era cloud computing is widely used by many users, so the computing and storage services are moving from cloud to edges. In edge computing, data is processed by the device itself or by a local computer or server, rather than being transmitted to a data centre. To deal with this problem the proposed system provides solutions of data encryption at data owner side before outsourcing. If data owner is valid then cloud service provider will send the tokens to data owner and data owner will be able to outsource the data. Also, user can find appropriate file by using keyword search rather than searching by file name. The proposed system provides a searching technique called K-Nearest Keyword searching algorithm to search the file keyword instead of file name. If any user wants to read or access the data, the user will send request to data owner. At the time of registration user will be authenticated by service provider using K-Map method. After the confirmation of valid user, service provider sends request to data owner for accessing data and approval will be given by data owner.Then user will be able to download the original data by using K-Map secret key.
