CREATING AN INFORMATION SYSTEM FOR A POLICE OFFICE AND CRYPTOGRAPHIC PROTECTION OF ITS INFORMATION

Abstract

Information systems for the service of the small settlements in the Republic of Bulgaria and their adjoining territory are not designed and integrated everywhere at the Ministry of Interior (MOI). Therefore, this article considers an option for building such an information system that would be useful for the activity of a micro-district police office.
After the analysis, we have come to the conclusion that the manual information processing is not efficient with regard to the processing time and at the same time a greater number of human resources are involved in the process. By creating such an information system, the time spent on storing and processing information would be significantly shortened. Undoubtedly, this would have a positive impact on the workload of police officers in smaller settlements. The integration of the information system in regions does not mean that it will result in state cuts. On the contrary - the tasks of the corresponding staff would be redistributed and the officers would do much more of their duties and they would do them more efficiently. By means of the modern information technologies, an optimal solution to arising problem situations is sought, namely in such services to the Ministry of Interior (MOI). A detailed analysis of the documents, by means of which this information is processed, is done. It includes requests such as document validation forms, requests for access to information, etc. According to the DB-Engines chart for November 2017, the Microsoft Access database management system ranks eighth (that is, the top 10) compared to the other 337 systems. Another IT Career Success rating also identifies Microsoft Access in the top 10 of database management systems. In this chart it is in ninth position. The capabilities of Microsoft Access 2016 have been analyzed compared to the previous versions of the information systems design. This environment is discussed in greater details in the discipline of Databases and Applications and it is namely this that is used to build the information system described in the article. In order to limit data from unauthorized access, we have used cryptographic protection. It has been created with a PHP scripting language with a syntax based on C and Perl. The algorithm of the encryption and decryption software that we have used is effective and successfully passed the statistical tests with the National Institute of Standards and Technology (NIST) for resistance to attacks.
