Assuring Information Integrity in Mobile Cloud Computing: A Multi-Level Transaction Security Approach

Abstract

The spread of mobile cloud computing has made data integrity harder to guarantee. Transmitting data across distributed, resource-constrained environments exposes it to corruption, interception, and makes the transaction not complete in ways that existing single-layer security mechanisms do not adequately address. Encryption, blockchain, and provable data possession each target distinct points in the data lifecycle; none protects the full transaction. This study applies design science research to identify those limitations and to build a multi-layer transaction security framework that addresses them directly. The framework is organised around four interdependent components: identity authentication, data verification, fault tolerance, and efficiency optimisation. Testing was conducted in a simulation environment configured with 100 mobile devices, five cloud nodes, and 5,000 transactions across three scenario types. The framework achieved a 96% data integrity rate, compared with 85% for traditional encryption models. Transaction latency was 1.8 seconds, against 2.5 seconds for blockchain-only systems. Reliability under fault conditions reached 94%. The results support the case for integrated, lifecycle-aware security architectures in mobile banking, healthcare, and Internet of Things (IOT) deployments.
