YANES-PAVON, Jessica  e  DIAZ-PANDO, Humberto. Evaluation of data quality through messages authentication code. Ing. Ind. [online]. 2019, vol.40, n.1, pp. 37-47. ISSN 1815-5936.

The decision-making processes provide information of vital importance to any organization that intends to be competitive. Computer systems are fundamental for a good decision-making process. In this context, it is essential that the information that supports the decisions come from data that have the adequate quality, identifying integrity as one of the most important attributes. The principle of security is followed as an attribute of quality of the systems, particularizing in the security and quality of the data. The main contribution lies in the use of message authentication code for evaluating the quality that exhibits the data stored in a vulnerable data source. The results obtained in the experimentation reveal a variation of system response times, as well as an increase in the volume of the data source, after the proposed solution is incorporated.
