METHOD FOR TRANSMITTING A ONE-TIME CODE IN AN ALPHANUMERIC FORM

摘要

The subject of the invention is the method of transmission of a one-time code in an alphanumeric form by the computer connected to the telecommunication GSM or UMTS network after receiving by the computer the request for a one-time code, generating the one-time code and saving it into the computer's memory for the subscriber identifiable with the telephone number of the electronic display-equipped device, with which the computer routes and starts the connection via the telecommunication network; later in the CID fields of the IAM operation the computer places and sends to the electronic device the one-time code in the hexadecimal system. The code is displayed by the display system of the subscriber's electronic device when it is called. Preferably, in the CID fields not taken by the one-time code in an alphanumeric form the computer places and sends with the one¬ time code masking characters other than alphanumeric. Optionally, the one-time code in an alphanumeric form placed by the computer in the CID fields contains at least on masking alphanumeric character. The method can be used in many cases, serving the authentication of subscribers and telecommunication systems.
