Abstract

The invention concerns a device or machine used for payment and electronic currency systems and systems for billing or payment for data transmission in the network. The device or machine can insert, within the control structure associated with a data packet in a data-transmission network, a token containing a toll unit credit, and can initiate an electronic or physical machine-executed operation after having authenticated and debited the credit associated with the token belonging to a packet. The device or machine according to the invention allows billing or payment for transmission, the content of a data packet, or the service provided with respect to the content of a data packet.

Claims

1. Procedure for determining the components used to bill the cost, to at least one centralized financing organization, of the operations performed by a packet-switched network used to transmit data in datagram data packets, said packet-switched network comprising:

a plurality of communication nodes which carry out said operations by means of one or several operators and serving a plurality of users, wherein said procedure includes the following main steps;

a) assigning to each datagram data packet to be transmitted by a packet-switched network user a first value representing a "toll" monetary unit credit, as well as the identity of the centralized financing organization supplying the credit, the credit amount corresponding to the cost of the operations to be performed on each data packet in the data-transmission packet-switched network using at least one communication node;

b) recording the first representative value and the identity of the centralized financing organization concerned;

c) in at least the communication node, reducing the first representative value by an amount representing the cost of the operations to be performed on the data packet in the node in question;

d) recording the amount representative of the reduced representative value and the identity of the centralized financing organization;

e) for each user and each centralized financing organization, adding the first stored representative values in order to calculate a first total amount owed by the user to the various network operators through the centralized financing organization; and

f) for each operator and each centralized financing organization, adding the representative amounts stored in order to obtain a second total amount owed to the operator concerned by the various network users through the centralized financing organization.

2. Procedure according to claim 1, wherein the network user purchases from the centralized financing organization at least one toll token representing monetary units, and wherein said first represented value is debited on the toll token purchased by the user.

3. Procedure according to claim 1 or 2, wherein operation c) further comprises:

carrying out the operations on the data packet if the representative amount is equal to or less than the representative value;

not performing the operations on the data packet if the representative amount is greater than the representative value.

4. Procedure according to claim 1, wherein at least said value representative of the monetary unit credit and said amount representative of the reduction of said representative value are numerical numbers resulting from the performance of authentication functions on said representative value and on said representative amount.

5. Procedure according to claim 4, wherein the authentication function is applied to the identity of the centralized financing organization.

6. Procedure according to claim 4 or 5, wherein the authentication function is implemented on the content of the data packet.

7. Procedure according to claim 4, or 5, wherein the authentication functions are of the numerical signature type.

8. Procedure according to claim 4, or 5, wherein the authentication functions are procedures utilizing hashing functions.

9. Procedure according to claim 4, or 5, wherein the authentication functions are cryptographic procedures.

10. Procedure according to claim 4, wherein a non-duplication function is implemented on said value representative of the monetary unit credit so as to prevent the use of said representative value more than once.

11. Procedure according to any of claims 4, 5, or 10, wherein step a) includes the following main steps:

a1) calculate the representative value based on the cost of the operations to be performed on the data packet in the data-transmission network;

a2) calculate the numerical number by carrying out the authentication function; and

a3) inserting the numerical number in the data packet to be transmitted.

12. Procedure according to claim 11, wherein in the intermediate step a), calculation depends on the originating and terminal addresses of the data packet, on the number of communication nodes through which the data packet must transit, on the types of operations which said communication nodes must perform, and on the grades of the operations performed.

13. Procedure according to claim 12, wherein the intermediate step a3) consists in:

creating a "toll header" in each data packet, and

setting the parameters of this "toll header" so as to insert therein the numerical number.

14. Procedure according to claim 13, wherein a portion of the toll header is used to transmit to the operator information which enables it to process the content of the toll header.

15. Procedure according to any of claims 4, 5, or 10, wherein the representative values, the representative amounts, and the identities of the centralized financing organizations are authenticated randomly or on a probabilistic basis.

16. Procedure according to any of the preceding claims 1, 2, 4, 5 or 10, wherein the network user is a network access provider for other users, and wherein said access provider performs the functions of an operator for the other users.

17. Procedure according to claims 1, 2, 4, 5, or 10, wherein a data processing system is used to implement the invention.

18. System according to claim 17, wherein said data-processing system is personalized at each node belonging to the network and at each user'"'"'s site.

19. System according to claim 17, wherein said data-processing system is integrated into the information management system of each node belonging to the data-transmission network.

20. A method for determining components used to bill costs to a centralized financing organization, for operations performed on an Internet packet-switched network wherein data is transmitted in datagram data packets, in accordance with an IP protocol, from Internet service providers to the Internet network, the network including a plurality of communication nodes carrying out operations by a plurality of network operators that control segments of the Internet network, the method comprising the steps:

a) assigning to each datagram data packet, to be transmitted by an Internet service provider, a first value representing a toll monetary unit credit, as well as the identity of the centralized financing organization supplying the credit, the credit amount corresponding to the cost of the operations to be performed on each data packet in the packet-switched network using the nodes;

b) recording the first representative value and the identity of the centralized financing organization concerned;

c) reducing the first representative value by an amount representing the cost of the operations to be performed on the data packet in corresponding node;

d) recording the reduced representative value and the identity of the centralized financing organization;

e) for each Internet service provider and each centralized financing organization, adding the first stored representative values in order to calculate a first total amount owed by the Internet service provider to the various network operators through the centralized financing organization; and

f) for each operator and each centralized financing organization, adding the representative amounts stored in order to obtain a second total amount owed to the operator concerned by the Internet service providers through the centralized financing organization.

21. The method set forth in claim 20 wherein the cost of operations to be performed includes calculations of at least one of the following:

originating and terminal addresses of the data packet, the number of communication nodes through which the packet passes, the type of operations to be performed by the nodes, and the grades of operations performed.
