IT PROJECT OF DATA AUTHENTICATION VERIFICATION SYSTEM BASED ON BLOCKCHAIN TECHNOLOGY

Abstract

The developed information system is designed to help buyers of goods to identify the original product by placing two identification scan codes on the product, which lead to information located in a protected blockchain data structure. This system is economically feasible for companies producing goods, because it can significantly reduce material damage caused by manufacturers of counterfeit goods. A positive perception of this software product by potential consumers of goods is also expected, as the system will allow users to have exactly what they want - not to come across fakes and save money. The implementation of the IT project is based on three directions, such as working out problems, designing interconnections, and realizing a demo version of the project. Working out the issues is the theoretical and methodological foundation on which the following aspects will be based. An aspect is a collection of problem analysis, possible solutions and workarounds at different levels of system implementation. The success criteria of the aspect are persuasiveness and competitiveness. Persuasiveness shows the extent to which the implementation of the system inspires confidence in the final buyer of the goods. Competitiveness shows the security factor of the system in relation to methods of counterfeiting goods and ways of bypassing protection against counterfeiting. The set of criteria determines the level of success of the project, provided that the criteria of the following aspects are met. The second aspect is designing relationships. This aspect involves defining the system architecture and the connections between them at different levels of implementation. Sets the behavior of the product in its application. The criteria for this aspect are flexibility and stability. Flexibility provides the ability to expand the system with as little effort as possible, as well as the fine configuration of individual components without global intervention in the implementation. Stability determines how much the system can work without deviating from expectations when the load increases or the scale of the implementation increases. The last aspect is the implementation of the system. The aspect is responsible for all stages of the implementation of previously prepared plans into reality. Implementation is the longest and most demanding. It is necessary to start this stage after complete completion of the previous ones. The criteria of the last aspect are accuracy and security. Accuracy shows the ratio of the number of successfully detected original products to all product detection attempts by the developed system. Security shows the degree of system protection against possible attacks and methods of data compromise.
