description: Topic of the final qualifying work: "Masking in NoSQL-databases of the key-value type. This work is devoted to ensuring data security in NoSQL DBMS of the key-value type by developing a method for masking records. Tasks that were solved during the research: 1. Analyze data access in A nosql key-value DBMS, determine requirements and approaches to implementing masking. 2. The analysis of hashing algorithms to implement masking within databases like key-value. 3. Implement data masking in NoSQL DBMS of key-value type and evaluate the results. This thesis presents a study of the masking mechanism in different types of database management systems and provides a class of tasks in which it is applicable. A comparison is made of different approaches to organizing masking in non-relational databases of the key-value type. Requirements for the masking system are formulated. The analysis of hashing algorithms that are suitable for adding attribute access control to masking is performed, and an algorithm that meets the requirements is selected. As a result, we developed a prototype of a system that provides data security in the key-value store. The qualitative and temporal characteristics of the implemented solution are evaluated.
