<p>The invention concerns a method and a system for making secure a transaction via a telecommunication network, the method involving at least a client (C1), a goods and/or services supplier (F1) and a control entity (EC). Said method is characterised in that it consists, once the client (C1) has decided about the transaction with said supplier (F1), in using a closed telecommunication network (RTF) such as a telephone network, which requires dialling a call number to set up a communication between the client (C1) and the control entity (EC) to cause said communication to be set up at the request of one or the other, so as to enable the client (C1) to validate his transaction and the control entity (EC) to identify the client. The invention is particularly applicable to electronic commerce on the Internet.</p> |
