Method for providing a dynamic code via a telephone

摘要

A user provides an identifier to a computer server operating an online service by means of a network terminal connected to the computer server by a digital network. The user also provides a dynamic code that is to be used with the online service. The dynamic code is made up of a subset of digits that make up the number of a calling line, selected by a code server from among a set of available lines, so as to call the telephone of the user. The number for the dynamic code is transmitted to the online service by the code server. The dynamic code is extracted from the number for the calling line on the basis of an extraction rule indicated by the online service on the network terminal of the user.

1. A method for supplying the user of an online service with a dynamic code via a telephone, comprising:
supplying, by said user, by means of a network terminal connected to said computer server by a digital network, an identifier to a computer server operating an online service; selecting by a code server a calling line from a set of available lines to call a telephone of the user and used for calling the telephone of the user; determining a dynamic code to be used with the online service, wherein the dynamic code is determined by a dynamic code extraction rule that designates a subset of the digits that make up the number of the calling line to be taken into account to make up the dynamic code; and transmitting the calling-line number to the online service by the code server, wherein the number of the calling line, containing the dynamic code, is determined by an algorithm implemented by the code server, on the basis of a set of parameters included in a dynamic code request transmitted by the online service.
