A solution that interfaces information systems (cross-system interfaces) to automatically receive data and, if necessary and legally justified, information about changes made to it (monitoring solution). Data is transferred from the system of the Register of Natural Persons to the system of the person requesting the information by means of cross-system interfaces, when submitting requests by the personal identity number. During the development of the system, access to the test environment of the Register of Natural Persons is provided, and after the development of the system, testing of the system must be carried out and a deed of completion of the development of the system must be signed. Access to the production environment of the Register of Natural Persons will be provided after the signing of the deed.

The solution of cross-system interfaces is designed to facilitate the processing of personal data received from the Register of Natural Persons in the system of the person requesting the information. If it is necessary to call several data groups at the same time, the OCMA offers to create composite data set(s) from the data groups specified by the information requester. The composite data set ensures that the necessary data on the person concerned is available in a single call, thus also reducing the time needed to process the personal data request as a whole.

This solution has an additional service (monitoring) that provides the requester with the possibility to retrieve information on which data of persons registered in the requester’s system have changed. To use the monitoring service:

1) the information requester shall specify the data sets to be monitored and shall send the personal identity numbers of the persons to be monitored to the Register of Natural Persons via the relevant monitoring service;

2) after the start of the monitoring process, the information requester has the possibility to find out the fact of a change in the data of the persons monitored through the relevant monitoring service;

3) after this fact has been established, the requester shall have the possibility to retrieve from the Register of Natural Persons, using the appropriate services, the up-to-date data to be monitored;

if, as a result of the service provision process, there is no longer a need to monitor the data of any persons, the information requester shall send the personal identity numbers of those persons to the Register of Natural Persons using an appropriate monitoring service.
