Data Integrity Verification in Cloud Computing

Cloud computing is recognized as a hottest technology which has a significant impact on IT field in the nearby future. Cloud computing is an Internet based computing. It provides the services to the organizations like storage, applications and servers. Cloud computing is on demand and pay per use service. That means customers pay providers based on usage. Data Integrity is the major issue in cloud computing. To provide the integrity various methods have been proposed by the researchers. In this paper we will proposed a model which will provide the data integrity using Elgamal Algorithm and SHA-2 Algorithm. The Proposed model shows that the data which is uploaded on cloud is secured if the hash key matches with the local keys which are stored on the system.
