Tims: A Secure Testing-Machine Information Management System

The testing information refers to the data obtained by the quality inspection center after testing steel, cement and other materials through testing machines and other instruments. The quality inspection center issues a report according to the testing result, which serves as the basis for the batch of materials to be put into the market. At present, the information level of testing-machine information management is relatively low, and there is no safe and effective management mechanism. In order to solve this problem, this paper proposes TIMS, a secure testing-machine information management system, which adopts the separation-of-three-rights management mode and a secure identity-binding interface to improve the management efficiency as well as ensure the security of data and workflow. At the same time, we combine the watermark QR code technology aiming at report anti-counterfeiting. We implement the prototype of TIMS, which realizes the above functions and provides a user-friendly interface for management and statistics. (c) 2021 The Authors. Published by Elsevier B.V.
