Abstract

A method of conducting secure transactions over a communications network (50) includes registering members. The registered members (30) are each assigned a unique user ID and have a financial account associated therewith. Registered members (30) connected to the communications network (50) are logging in with their unique user ID, and assigned a unique session code. The method further includes receiving purchase authorization requests from merchants (20). Each of the purchase authorization requests indicates a purchase amount and a session code. The validity of session codes indicated in received purchase authorization requests are then verified.

Claims

1. A method of conducting secure transactions over a communications network, the method comprising:

(a) registering members, said registered members each being assigned a unique user ID and having a financial account associated therewith;

(b) logging in registered members connected to the communications network with their unique user ID;

(c) assigning logged in members a unique session code;

(d) receiving purchase authorization requests from merchants, each of said purchase authorization requests indicating a purchase amount and a session code; and

,

(e) verifying the validity of session codes indicated in received purchase authorization requests.

2. The method according to claim 1, wherein each unique session code is only valid while the respective member is logged in for a particular session.

3. The method according to claim 1, further comprising:

(f) determining if the respective financial account is sufficient to cover the purchase amount indicated in its corresponding purchase authorization request.

4. The method according to claim 3, wherein if the session code is valid and the respective account is determined to be sufficient to cover the purchase amount, then in response to the purchase authorization request, the method further includes:

(g) establishing an authorization code, said authorization code being communicated to the merchant from which the purchase authorization request was received.

5. The method according to claim 1, wherein a persistent communication link is established when a member is logged in, such that when the communication link is terminated the unique session code associated therewith is no longer valid.

6. The method according to claim 5, wherein the persistent communication link is maintained so long as the member is logged in.

7. The method according to claim 5, wherein the persistent communication link is not broken when the member accesses other sites on the communications network.

8. A transaction processing system for authorizing purchases over a communications network, said system comprising:

a server by which a presence is maintained on the communications network;

registration means for registering members to use the transaction processing system, said registration means establishing unique user IDs for each registered member and associating respective financial accounts therewith;

log-in means for logging in registered members using the communications network, said logged in members being identified by their respective user IDs;

tagging means for assigning a unique session code to each logged in member;

receiving means for receiving purchase authorization requests from merchants, each of said purchase authorization requests indicating a purchase amount and a session code; and

,

validating means for verifying the validity of session codes indicated in received purchase authorization requests.

9. The transaction processing system according to claim 8, wherein each unique session code is only valid while the respective member is logged in for a particular session.

10. The transaction processing system according to claim 8, further comprising:

determining means for determining if the respective financial account is sufficient to cover the purchase amount indicated in its corresponding purchase authorization request.

11. The transaction processing system according to claim 10, further including authorizing means wherein if the session code is valid and the respective account is determined to be sufficient to cover the purchase amount, then in response to the purchase authorization request, the authorizing means establishes an authorization code, said authorization code being communicated to the merchant from which the purchase authorization request was received.

12. The transaction processing system according to claim 8, wherein a persistent communication link is established by the log-in means when a member is logged in, such that when the communication link is terminated the unique session code associated therewith is no longer valid.

13. The transaction processing system according to claim 12, wherein the persistent communication link is maintained so long as the member is logged in.

14. The transaction processing system according to claim 12, wherein the persistent communication link is not broken when the member accesses other sites on the communications network.

15. The transaction processing system according to claim 8, wherein the tagging means communicates the unique session IDs to the respective logged in members such that they can be communicated to merchants from the members shopping at merchant sites maintained on the communications network.
