METHOD FOR PRIVATELY TRANSMITTING INFORMATION BETWEEN USERS OF A DATA TRANSMISSION NETWORK

摘要

The invention enables a network user to organise the private address space and makes it possible to protect against unauthorised distribution of information. At the beginning, one or more messages about the person of an information receiving user are formed in the device of said information receiving user and are transmitted to the address of a boundary network intermediate device, in which the messages and the address of the device of the information receiving user are recorded, the messages formed in the device of the information receiving user are transmitted from the boundary device to the address of a second intermediate device, in which the messages and the address of the boundary device are recorded. Then, a message about the person of the information receiving user is formed in the device thereof and is transmitted to the address of the network intermediate device which is boundary for said device and in which the received messages are transmitted to the address of the second intermediate device. The message about the person of the information receiving user is formed in the device of said user and is transmitted to the address of the network intermediate device which is boundary therefor and in which the received messages are transmitted to the address of a second network intermediate device. In the second intermediate device, the message about the person of the user received from the information sending user is compared with the earlier received messages about the person of the information receiving user, the address of the intermediate device, which is boundary for the information receiving user, is determined on the basis of the results of comparison and the messages of the information sending user are transmitted to said boundary device. In the intermediate device, which is boundary for the information receiving user, the received and earlier recorded messages about the information receiving user are compared, the address of the device of the information receiving user is determined on the basis of the comparison results, and the messages of the information sending user are transmitted to the address of the device of the information receiving user.
