    Abstract: A method and system are disclosed for generating and using a virus-free file certificate. The method, for use in a virus-free certificate authority ( 102 ), includes the steps of: receiving ( 300 ) a virus-free certificate request for a file from a server ( 101 ) or a client ( 100 ) system; determining ( 301 ) whether the file is virus-free or not; if the file is declared virus-free by the virus-free certificate authority ( 102 ): generating ( 303, 304 ) a virus-free certificate ( 200 ) including a file signature ( 207 ) for certifying that said file is declared virus-free by the virus-free certificate authority ( 102 ); sending ( 306 ) back in response to the virus-free certificate request the virus-free certificate ( 200 ). The method, for use in a server ( 101 ) or client ( 100 ) system, includes the steps of: determining ( 400 ) whether a virus-free certificate ( 200 ) is associated with a file; if a virus-free certificate is associated with the file: authenticating ( 404 ) the virus-free certificate ( 200 ), said virus-free certificate including a certificate signature ( 206 ); authenticating ( 407 ) the file, said virus-free certificate ( 200 ) including a file signature ( 207 ), said file signature certifying that said file has been declared virus-free by a virus-free certificate authority ( 102 ).

    Abstract: A method for validating an electronic payment by a credit/debit card in a transaction system. The method includes registering a purchase of an article by a buyer using a credit/debit card associated with at least one PIN code, checking that the at least one PIN code is associated with the number of said credit/debit card provided by said buyer to said seller terminal, checking, by said electronic payment center, whether or not said at least one PIN code is valid, and one of: after the at least one PIN code is found to be valid, checking, by said electronic payment center, whether the electronic payment center has received a pre-validation from a third party; after the at least one PIN code is found to be valid, contacting a third party via a communication network and requesting that the third party validate the purchase; and after the at least one PIN code is found to be valid, contacting a third party via a communication network and requesting said at least one PIN code from the third party. The third party is a prime owner of the credit/debit card.

    Abstract: Coupling device for the connection of a Data Circuit Terminating Equipment DCE to a given Public Switched Telephone Network PSTN and to a local telephone set. The coupler includes means for providing said local telephone set with DC current whereby the microphone and the headphone of the telephone can be used respectively for transmitting and receiving vocal messages from the a DTE which is connected to said DCE. The invention also provides a DCE for the connection of a DTE toga a PSTN and to a local telephone set including a coupler circuit having the electronic components matching the electric requirements of a given PSTN. The coupler further includes means for providing the telephone set with DC current whereby vocal messages can be transmitted and received from the DTE to the telephone set. The invention further provides a DCE for the connection of a DTE to a PSTN and to a local telephone set which includes means for removably attaching a coupler circuit having the electronic components matching the electrical requirements of a given PSTN and further including means for providing the telephone set with DC current whereby vocal messages can be transmitted and received from the telephone set to the DTE.

    Abstract: COUPLING DEVICE TO BE CONNECTED TO A DCE FOR ALLOWING THE CONNECTION TO DIFFERENT PUBLIC SWITCHED TELEPHONE NETWORKS, DCE AND WORKSTATION INCLUDING THE SAME Coupling device according to the invention for connecting a DCE to a PSTN including the electronic components matching the electric requirements of a specific PSTN. The coupling device comprises plugging means for removably connecting the latter to the DCE, means for storing an identification code corresponding to a specific type of PSTN to which the coupler is intended to be connected to. The coupling device further comprises means responsive to a control signal received from the DCE for transmitting the identification code to the DCE. The DCE connected to the coupling device includes processing means and a storage for storing tables, each table comprising data characterizing a specific PSTN which the DCE is intended to operate with. The DCE reads the identification code during an identification phase by transmitting the control signal and selects in response to said reading the appropriate table corresponding to the coupling device. Therefore, by simply connecting an appropriate coupling device, a same DCE can be easily adapted to operate with a specific PSTN. Moreover, since the voluminous components are located into the coupling device, the DCE can be easily integrated, for example in one workstation.
