On line security method

Method for online authentication, and/or payment, and/or order, and/or purchase on a network such as Internet, employing one-use signs, called “ephemeral numbers” which are edited in duplicate by an issuer;

• the latter keeps one of said duplicates, and delivers the other of said duplicates to an entity which is a previously identified internaut listed with it;
• said duplicate is recorded on a data medium;
• said entity manually transmits one of said ephemeral numbers online and this transmission is then authenticated by the comparison of said ephemeral number with its duplicate and thus constitutes an authentication and/or a payment online,
• wherein said method makes it possible to obtain the following novel technical effects of:
• producing an online authentication, and/or payment, and/or order, and/or purchase on a network such as Internet, by the simple act of introducing a data medium into a computer,
• effecting such execution from any computer connected to a network, without said internaut customer having to adapt this computer, configure it or record anything whatsoever, before, during and after such execution,
• effecting such execution when a Web page representing a product and/or a desired service is displayed on the screen,
• effecting such execution on any Web page, without the latter needing to be configured for the use of the present method,
• effecting such execution on any Web site without the latter needing to have a payment terminal and/or an authentication system available, or needing to be configured for the use of the present method or even to be informed of its existence,
• effecting such execution on any Web site, without the latter needing to have available a specific service provider other than said issuer to effect a sale, and/or a service and/or collection of payment online, in accordance with the present method, said novel technical effects are obtained by the combined recording on said data medium, of said duplicate of ephemeral numbers and of an executable software comprising data-processing steps allowing:
• the online capture of the Web page which is displayed on the screen of said computer,
• the online dispatch of said captured Web page,
• the online dispatch of various data and information,
• the online dispatch of one of said ephemeral numbers taken from said medium and, at every new dispatch, a fresh said number likewise taken each time from said medium;
• said software is executable from said medium and is automatically executed after its introduction into said computer;
• and
• said dispatches are effected by electronic mail, and/or by webmail, or directly on a server or by any means other than by Internet, online or offline;
• and
• the address of the recipient of said dispatch(es) is that of said issuer.
