Abstract— This paper introduces a solution called Tenant-Oriented Duplication Integrity Checking Scheme (TDIC) to address the challenges faced in the Software-as-a-Service (SaaS) environment. In SaaS, tenants often create multiple customized duplicates of their data and distribute them across different data nodes for reliability. However, untrustworthy service providers can manipulate or delete the tenants' data, and they may store fewer copies than required.To overcome these issues, TDIC proposes a challenge-response model based on tuples sampling. It also introduces a new authentication structure called Tenant Duplication Authentication Structure (TDAS) that relies on tenant physical tuples. By incorporating homomorphism labels, TDIC enables data duplication verification without the need for local copies. Moreover, TDIC utilizes periodic random sampling to reduce complexity in constructing verification objects on the service provider's side and minimize unnecessary communication overhead.Overall, TDIC offers an effective approach to ensuring data integrity in SaaS by introducing a tuples sample-based challenge-response model and leveraging TDAS with homomorphism labels. It simplifies the verification process and enhances security in the face of untrustworthy service providers.
