METHOD OF TRANSFERRING ANONYMOUS DATA TO AN UNTRUSTED PARTY Russian patent published in 2021 - IPC G06F21/00 

FIELD: information technology.

SUBSTANCE: invention relates to a method for providing anonymity when routing data in a client-server architecture. According to the method, the data structure is divided on the client side. The data structure is intended to be sent to the server. The data structure is divided into a substructure containing critical data (hereinafter referred to as CD); a substructure not containing CD. The primary transformation of the data substructure containing the CD is carried out on the client side without the possibility of reverse transformation of the data by an anonymization device. After that the data including a substructure that does not contain CD and the transformed substructure of data containing CD are sent to the node with the device of anonymization. The node with the device of anonymization is not on the same Intranet with the server or the client. Secondary transformation of each received substructure of data containing CD is carried out by the anonymization device without the possibility of reverse transformation on the server or the client side. The data substructures are transferred from the anonymization device to the server.

EFFECT: invention ensures the anonymity of sending critical data to the server.
