Nowadays people store much of their information in Cloud, which is a vast network of remote servers, each with a unique function. Cloud storage provides reliable storage space for the users where the data can be stored in pay-as-you-go pricing model. Cloud storage data is monitored, backed up and remotely maintained. The Cloud Storage provides the benefits of low-cost storage, easy accessibility of data and disaster recovery of the data but faces challenges on confidentiality, data security and integrity of the data. Data integrity and verification checks whether the data stored in the cloud is unaltered as the data may be altered by cloud service providers or by malicious attackers. This paper gives a brief introduction about different techniques used for data integrity and verification for cloud storage and classification of them based on the security level provisioning used in the techniques.
