Data integrity or data quality plays a vital role in the storage reliability and security. With the advances in technological trends in storage, new challenges of data integrity surfaces. In this paper we discuss some key challenges in data integrity and suggest a blockchain based solution to solve data integrity problem in Location Based Servers. We designed and implemented a smart contract and query/update application to suit the needs of Location Based Servers. Implemented the Geo server on Hyperledger Fabric and tested the working of smart contract and query/update application on the testbed created. Our work show that proposed blockchain based solution is efficient and helps preserve privacy and confidentiality, highlighting the rich features and benefits.
