A method for generating a digital fingerprint by means of a pseudo random numbers codes

摘要

A method for assuring that a client - device is authorized to receive information from a system, wherein the system and the client - device via a network in bidirectional connection, and wherein said method comprises the steps of:Use of a identification information which a client - device unambiguously identified, as an input for a cryptographic hash function, in order to obtain a unique registry - id - code for the client - device;Use of a system that the client - device about the unique registration code, together with an additional user - identification information, an identity of the client - device to identify himself; andUse of the system, to a unique pseudorandom number (prn) to produce;andProviding the unique prn to the client - a device for use in the case of subsequent requests to information from the system during a bidirectional communication session.
