Recently, the Software-as–a-Service (SaaS) model has been gaining more and more attention. In SaaS model, both applications and databases will be deployed in servers managed by untrustworthy service providers. Thus, the service providers might maliciously delete, modify or falsify tenants’ data due to some reasons, which brings great challenge to adoption of SaaS model. So this paper defines data integrity concept for SaaS data storage security, which could be measured in terms of durable integrity, correct integrity and provenance integrity. Basing on the meta-data driven data storage model and data chunking technology, SaaS data integrity issues will be mapped as a series of integrity issues of data chunks. Via cyclic group, data chunks traversal approach for verification is presented, and then SaaS data integrity verification can be realized based on the integrity verification of data chunks. Also, we demonstrate the correctness of the mechanism through analysis in this paper.
