  "description": "<p>Data manipulation is often considered a serious</p>\n\n<p>problem in industrial applications as data tampering can lead</p>\n\n<p>to inaccurate financial reporting or even a corporate security</p>\n\n<p>crisis. A correct representation of company data is essential</p>\n\n<p>for the companies&rsquo; core business processes and is requested</p>\n\n<p>by governments and investors. However, the current solution,</p>\n\n<p>third-party auditing, is expensive and cannot be fully trusted.</p>\n\n<p>In this paper, we present the Data Warehouse Decentralized</p>\n\n<p>Integrity Model (DWH-DIM) to validate the integrity of the</p>\n\n<p>data warehouse and replace the current process. To address</p>\n\n<p>the challenge that the existing distributed integrity verification</p>\n\n<p>models cannot handle GDPR and are limited by scalability,</p>\n\n<p>our model uses a distributed file system to store attributes that</p>\n\n<p>can be used for the integrity verification task. The blockchain</p>\n\n<p>further confirms the authenticity of the files. Based on the</p>\n\n<p>proposed model, we present a detailed implementation of the</p>\n\n<p>DWH-DIM tool. The implementation is tested with a use case</p>\n\n<p>and several benchmarks. Experimental results demonstrate that</p>\n\n<p>our proposed model is feasible and meets the requirement for</p>\n\n<p>certificate warehouse data.</p>",
