Definitions
- the present invention relates to a method of registering a first entity called "the buyer” with a second entity called "payment server”.
- the invention relates to a registration method in which the buyer has a subscriber number to a telephone network and a secure module.
- the secure module generally consists of a bank card given to the buyer by his bank.
- - a visual integrating information on the holder including the name, and identification information of the bank card itself (the number of the bank card and its expiry date of validity).
- the present invention also relates to a remote payment method based on the registration method according to the invention, said remote payment method involving a third entity called "the seller" having a second telecommunications equipment which is capable of establishing a connection with the payment server, the electronic payment method comprising a preliminary exchange which is established between the buyer and the seller, with a view to the completion of a transaction,
- the payment server uses the information contained in the visual to carry out the remote payment process.
- This process is qualified in France as a Distance Selling procedure. Only the information bank card number and expiry date of validity are used to constitute said process. This type of process is commonly used today on the Internet but also in the context of distance trade (Mail Order);
- the payment server uses information contained in the magnetic strip to carry out the remote payment process.
- This process no longer exists in France in the context of local trade, except in the case of processing of foreign bank cards or in the event of a chip failure (see).
- automatic machines notably petrol pumps
- the automaton was equipped with a specialized circuit provided with the secrets necessary to carry out this verification. This process is commonly used outside of France.
- a major drawback of the methods described above resides in the fact that a dishonest buyer can easily duplicate such a bank card or recover the number and expiry date of its validity, or even fraudulently use the real card buyer's bank account.
- the method of electronic payment based on the use of such a bank card is certainly advantageous from a confidentiality point of view of the purchase.
- the registration method according to the invention is characterized in that it comprises the following steps:
- the buyer sends a confidential message to the server via a first telecommunications device, said message comprising information relating to the buyer's secure module and to the buyer's telephone subscriber number,
- the server assigns to the buyer's telephone subscriber number information relating to the buyer's secure module, in the event that the result of this verification is positive,
- the server sends the buyer a payment code (key) intended to be authenticated by the server during a payment made by the buyer.
- the buyer's registration with the payment server is thus secure since it is linked to information from the buyer's secure module.
- one and / or the other of the following arrangements are used: - the payment code or key is the same for each payment;
- Kn f (Ko)
- Kn-i f (Kn)
- f being a non-invertible function and Ko a root payment code provided by the server to the buyer;
- the first telecommunications equipment is a public telephone booth comprising a means of reading said secure module of the buyer; - the payment server sends the buyer, in addition to the payment code or key, information relating to a pseudonym of the buyer's secure module.
- the electronic payment method based on registration it is characterized in that following the preliminary exchange between the buyer and the seller, it includes at least the following exchanges:
- the buyer sends to the seller, via a third telecommunications device, a message including either the buyer's telephone subscriber number, or information relating to the buyer's secure module, or information relating to a pseudonym of the buyer's secure module,
- the seller sends a message to the server comprising, on the one hand, information relating to the transaction and, on the other hand, either said telephone subscriber number, or information relating to the buyer's secure module, or information relating to the pseudonym of the buyer's secure module,
- the server dials the buyer's telephone subscriber number and sends him an information message comprising said data relating to the transaction
- the server checks the accuracy of said payment code or key and, if the result of this verification proves positive, validates the payment.
- FIG. 1 schematically illustrates the method of registering a buyer with a payment server, in accordance with a first embodiment
- FIG. 2A illustrates a diagram for obtaining, by the payment server of FIG. 1, the payment code given to the buyer at the time of his registration,
- FIG. 2B represents a variant of the diagram of FIG. 2B
- FIG. 3A schematically illustrates a first embodiment of the electronic payment method based on the registration method represented in FIG. 1,
- FIG. 3B schematically illustrates a second embodiment of the electronic payment method based on the registration method represented in FIG. 1,
- FIG. 3C schematically illustrates a third embodiment of the electronic payment method based on the registration method represented in FIG. 1,
- FIG. 3D schematically illustrates a fourth embodiment of the remote payment method based on the registration process shown in Figure 1.
- the reference numeral 1 designates a secure module belonging to a buyer A who has a subscriber number N to fixed or mobile telephone network
- the alphanumeric reference E1 denotes a first telecommunications device, in particular a terminal which includes a reader 2 capable of reading the information contained in the secure module 1
- the alphabetical reference T denotes a payment server with which the buyer A must register prior to any electronic payment step.
- the payment server T is intended to record the payment and to update the respective accounts of the buyer A.
- the secure module 1 of the buyer A is a smart bank card to which is assigned a confidential payment code C, an NC number and an expiration date DE of said card.
- the telecommunications equipment E1 consists in turn of a public telephone booth, which has the advantage of being accessible to any buyer, and in particular to those who have neither a personal computer nor a two-slot mobile terminal.
- the payment server T comprises a telephone type link with the buyer A.
- the telecommunications equipment E1 consists of a computer belonging to the seller involved in the remote payment process, said computer then being provided with a reading device provided with two slots respectively provided for receiving the secure module 1 of the buyer A and the seller's secure module.
- the telecommunications equipment E1 consists of a computer belonging to buyer A, said computer being connected to a device for reading the secure module 1 of buyer A ,. According to yet another variant, the telecommunications equipment
- E1 consists of a two-slot mobile terminal.
- the process for registering buyer A with the payment server T takes place as follows.
- the payment server T sends a voice or data message to buyer A of the type: "insert your bank card 1 into the reading device 2, type your confidential code C and your telephone number N";
- buyer A introduces his bank card 1 into the reading device 2 and enters on the keypad of the public telephone E1 his confidential code C and his telephone number N and, possibly, an additional confidential code if his bank card is equipped.
- the step for entering the confidential code C is for example carried out using an input algorithm stored in the public telephone E1;
- the public telephone E1 locally checks the confidential code C and, if this verification proves to be correct, generates an electronic signature of the buyer using an algorithm and a key present in the bank card;
- the payment server T assigns the bank card number NC and the expiry date DE of the bank card 1 of buyer A to the telephone number N of buyer A and stores this correspondence in a database 4 provided for this purpose in the payment server T;
- the payment server T calculates a payment code or key K and addresses this data to the buyer A, via the public telephone E1, said data being possibly supplemented by a pseudonym number NCP of the bank card 1 of the buyer A, this number being accompanied by an expiry date DEP of said pseudonym.
- the pseudonym number NCP is automatically calculated by the payment server T who must, for this purpose, have beforehand the BIN number (English abbreviation for Bank Identification Number) located at the top of the NC number of the bank card 1 'buyer A and correctly calculate a key called "Luhn's key" which is actually the last digit of the NC number of the bank card 1 of buyer A.
- BIN number English abbreviation for Bank Identification Number
- the pseudonym number NCP integrates the telephone number N of the buyer A, on the condition that the payment server T possesses beforehand the number BIN and correctly calculates the Luhn key.
- the pseudonym number NCP integrates an encrypted telephone number N of the buyer A on the condition that the payment server T previously has the number BIN and correctly calculates the Luhn key.
- step 7 the registration phase of the buyer A with the payment server T is then considered to have ended.
- step 6 if the verification does not prove to be exact, the payment server T sends the bank card management system a notification for suspected fraud of said bank card 1.
- the payment server T affects everything even the bank card number and expiry date of the credit card of buyer A to the phone number N of buyer A and stores this correspondence in said database with an indication of suspected fraud.
- step 7 the payment server T has the possibility of addressing the code or the key K via telecommunications equipment other than the public telephone E1, in particular telecommunications equipment belonging to buyer A.
- the code or the key K can for example be sent in the form of an electronic message to the personal computer PC of the purchaser A or in the form of a short message on the mobile phone of the latter, etc.
- the payment code or key K is intended to be presented by buyer A during the electronic payment process based on the registration described above and a detailed description of which will be given in the following description.
- the key K is fixed.
- the advantage of such an arrangement lies in the simplicity of its implementation since it does not require any particular equipment, hardware or software, at buyer A, who simply has the constraint to remember this key.
- the buyer A addresses the key K to the payment server T which compares it with that stored locally during the registration phase in order to accept or refuse the transaction, according to the result of this comparison.
- This second embodiment has the advantage of continuously varying the key K presented by the buyer A on each payment. It also requires the implementation of a calculation and data processing program on the phone of buyer A. In addition, the maximum number of payments is limited to n, which can be a security advantage. Thus, when the buyer A has exhausted the n + 1 keys of the series at the end of the nth payment, he represents himself on telecommunications equipment E1 comprising a secure smart card reader to recreate a new series Un.
- Buyer A addresses the key K n- ⁇ to the payment server T which calculates f 1 (K n- ⁇ ) and compares f 1 (K n- ⁇ ) with the key K n sent by buyer A during payment of rank 1, this in order to accept or refuse the transaction, according to the result of this comparison.
- the program of installed calculation loaded in the server tolerates row shifts depending on parameters related to the degree of security it has set.
- Buyer A sends the key K 2 to the payment server T which calculates E “1 (K 2 ) and compares E “ 1 (K 2 ) with the key Ki sent by buyer A during the payment of rank 1, this to accept or reject the transaction, depending on the result of this comparison. Payment steps similar to those described above are thus iterated until payment of rank n.
- the registration phase which has just been described above is possibly supplemented by an additional registration phase on a Web server (not shown) connected to the payment server T.
- buyer A provides additional information to the web server such as, for example, its delivery address.
- additional information can of course be validated by the Web server only after presentation, using the purchaser's telephone A, of the key K addressed in step 7).
- the procedure for such a complementary registration phase is as follows. Buyer A connects to the web server.
- the payment server T then dials the telephone number N of the buyer A and invites him to present his key K or Ko according to the embodiment implemented.
- the web server invites buyer A to continue entering additional information in the registration grids displayed on a web page of the web server, provided that the key K or Ko is authenticated by the payment server T.
- the telepayment operation which relates more specifically to the invention is preceded by a preliminary exchange or negotiation between seller V and buyer A.
- This negotiation may have been carried out remotely (by telephone, by Internet, etc. .) or simply have been carried out during an interview between the buyer and the seller.
- the outcome of the negotiation consists of an agreement by the buyer A for the payment of an amount MT of a service due by the seller V.
- the alphabetical reference T designates the payment server with which the buyer A has previously registered in the manner described above.
- the payment server T is also connected:
- the equipment E2 consists for example of a Web server hosting one or more remote sales sites.
- the equipment E3 consists, for example, of a personal computer PC.
- the buyer A addresses his telephone number N to the server E2
- the server E2 addresses to the payment server T information relating to the transaction in progress, such as for example the amount MT due by the buyer A, as well as the telephone number N of buyer A
- the payment server T dials the telephone number N of buyer A, sends him the information received in step 2) and invites him to present the key given at the time of registration described above,
- buyer A sends the key K or Ko to the server T, depending on the embodiment implemented, 5) the payment server T verifies said key as described above and if the result of this verification is positive, the payment server T matches the telephone number N of the buyer A with the number of the bank card 1 of the buyer,
- the payment server T addresses to bank B1 of buyer A an authorization to debit the bank account of buyer A in accordance with the procedure called "Distance Selling", 7) bank B1 sends the payment server T a message acknowledging said authorization,
- the payment server T sends the server E2 a message according to which the amount MT has been paid by the buyer A.
- the method of electronic payment described above implies that the server
- E2 includes software means designed to:
- the remote payment method according to this third embodiment differs from that of FIG. 3B by the fact that following negotiation between buyer A and seller V, seller V sends a message to buyer A asking him to send him, instead of his bank card number NC and the expiration date DE of validity of said card, an NCP number of pseudonym of bank card 1 of buyer A and a expiration date DEP of validity said pseudonym.
- the remote payment process then proceeds as follows:
- the purchaser A addresses to the server E2 the pseudonym number of the NCP bank card as well as the expiry date DEP of validity of said pseudonym,
- the server E2 sends information to the payment server T relating to the transaction in progress, such as for example the amount MT due by the buyer A, the pseudonym number NPC as well as the due date DEP,
- the payment server T matches the NPC number received with the telephone number N of buyer A, dials the telephone number N of buyer A, sends him transaction information received in step 2) and invites him to present the key given at the time of the registration described above,
- buyer A sends the key K or Ko to the server T, depending on the embodiment implemented, 5) the payment server T verifies said key as described above and if the result of this verification is positive, the payment server T matches the pseudonym number NCP with the number of the bank card 1 of buyer A,
- the payment server T addresses to bank B1 of buyer A an authorization to debit the bank account of buyer A in accordance with the procedure called "Distance Selling",
- bank B1 sends the payment server T a message acknowledging said authorization
- the payment server T sends the server E2 a message according to which the amount MT has been paid by the buyer A.
- server E2 comprises software means designed to:
- the payment server T can, in a manner known as such, place, following step 6), the amount MT in discount, or else submit this amount in discount pending the seller V sends to the payment server T a confirmation message according to which the good bought by the buyer A to the seller V was indeed delivered by the latter.
- the remote payment method according to this fourth embodiment involves the same equipment as that shown in Figures 3A to 3C.
- the main difference compared to the three previous embodiments lies in the fact that the seller V is not subscribed to the payment server T.
- the remote payment process then proceeds as follows: 1) the buyer A addresses to server E2 the pseudonym number of bank card NCP as well as the expiry date DEP of validity of said pseudonym,
- the server E2 sends information relating to the transaction in progress to its bank B2, such as for example the amount MT due by the buyer A, the pseudonym number NPC as well as the due date DEP,
- bank B2 addresses, via an authorization network, the information received in step 2) to a bank authorization center (not shown) associated with the payment server T,
- the payment server T performs the conversion between the pseudonym NCP bank card number of buyer A and the telephone number N of buyer A, as well as the conversion between this NCP number and the bank card number NC of buyer A, dials the phone number N of buyer A, sends him the information relating to the transaction in progress received in step 3) and invites him to present the key delivered at the time of registration described above,
- the payment server T verifies said key as described above, 7) if the result of this verification proves to be positive, the payment server T addresses the bank B1 of the buyer A authorization to debit the bank account of buyer A in accordance with the procedure called "Distance Selling",
- the payment server T addresses the seller's bank B2 V a message that the amount MT has been paid by buyer A,
- bank B2 of seller V transmits this message to server E2 of seller V.
- the payment server T can, in a known manner as such, submit, following step 7), the amount MT of the discount transaction, provided that step 5) above is correctly carried out.
- the secure registration and electronic payment methods which have just been described above are intended to be applied in particular in electronic commerce via the Internet, such as for example remote auctions. More generally, such methods are intended to be applied in any telepayment service involving at least two people, each having appropriate telecommunications equipment, one being the buyer and the other the seller.
