When focusing on modern conditions in the field of processing heterogeneous data based on a situation-oriented approach, the task of using information systems with implemented cryptographic technologies during operation arises. One of the examples of such implementation are services and microservices available via the Internet. They provide opportunities to employ their capabilities to verify the authenticity of document enhanced digital signature by means of the published API. Situation-oriented databases (SODB) do not have their own certification authority and encryption-related functionality, but there are opportunities to work with RESTful services by establishing a network connection, thus, there is a research interest in model-oriented processing of heterogeneous documents in cryptographic services and obtaining results from it. To use cryptographic web services in model states, it will be necessary to develop and modify the hierarchical situational model of the SODB in order to enhance it with the ability to work with such services, where authentication of authorization tokens and operating several entry points at the same time are required. The model should also be structured by using specialized elements and methods. The involvement of such services can solve the problem of checking heterogeneous documents: whether they were signed with an enhanced qualified electronic digital signature, the result will be a verification report, the so-called protocol, which is then saved in the database. Such a research objective has not previously been considered from a scientific and technical point of view as part of the SODB project. At the moment, there are opportunities to create tools and methods of the model to solve this problem; the current course design information system based on SODB also exists. By developing the proposed SODB tools, it becomes possible to create applications with the capability to verify heterogeneous documents in cryptographic web services and at the same time avoid laboriousness when creating such applications.
