Abstract

A method, system and computer program product for prepayment of a service includes informing the user of the availability of a plurality of different services. An indication and request of a desired service is received from the user over a first communications link. The requested service is provided to the user over a second communications link. To indicate prepayment for the service requested an authentication key is received from the user. The validity of the authentication key received is verified and the service is provided if the authentication key is valid.

Claims

1. A method for prepayment of a content, comprising the steps of:

generating one or more authentication keys;

providing an authentication key validity database for verifying the validity of any of the one or more generated authentication keys;

delivering at least one of the one or more authentication keys to a user;

informing the user of the availability of a plurality of different contents for downloading;

receiving from the user over a first communications link an indication of a desired content and a request for the desired content;

receiving from the user the at least one authentication key to indicate prepayment for the requested content;

verifying the validity of the at least one authentication key by means of the validity database;

providing the requested content to the user over a second communications link; and

invalidating the at least one authentication key in the validity database in response to the providing of the requested content to the user.

2. A method according to claim 1, wherein an individual one of the one or more authentication keys is required each time a content is provided.

3. A method according to claim 1, the method further comprising:

arranging each of the one or more authentication keys to indicate a time period during which they are valid;

wherein verifying the validity of the at least one authentication key includes comparing a present date with the time period during which the at least one authentication key is valid; and

invalidating expired authentication keys.

4. A method according to claim 3, the method further comprising:

scanning the validity database to detect and remove invalid authentication keys.

5. The method according to claim 1, further comprising modifying the validity database on providing the requested content so that the monetary value corresponding to the at least one authentication key indicating prepayment is reduced according to a price of the content requested by the user.

6. A method according to claim 1, wherein the at least one authentication key is a printed user readable code.

7. A method according to claim 6, wherein the method further comprises printing a group of the at least one authentication keys on a card.

8. A method according to claim 1, wherein the method further comprises concealing the at least one authentication key with a non-reversibly removable concealing means.

9. A method according to claim 1, wherein the first communications link is based on at least on of the following:

a data network, a telephone network, a mobile telecommunications network, a local area network and a wide area network.

10. A method according to claim 1, the method further comprising:

allowing the user to test a content requested; and

receiving a final verification from the user before the user is provided with the content.

11. A system for prepayment of a content, comprising:

means for generating one or more authentication keys;

an authentication key validity database for verifying the validity of any of the one or more generated authentication keys;

means for delivering at least one of the one or more authentication keys to a user;

means for informing the user of the availability of a plurality of different contents for downloading;

means for receiving from the user over a first communications link an indication of a desired content and a request for the desired content; and

means for receiving from the user the at least one authentication key to indicate prepayment for the requested content;

means for verifying the validity of the at least one authentication key by means of the validity database;

means for providing the requested content to the user over a second communications link; and

means for invalidating the at least one authentication key in the validity database in response to the providing of the requested content to the user.

12. A computer program product for prepayment of a content, comprising:

computer readable program means for generating one or more authentication keys;

computer readable program means for providing an authentication key validity database for verifying the validity of any of the one or more generated authentication keys;

computer readable program means for causing a computer to provide at least one of the one or more authentication keys to a user;

computer readable program means for causing a computer to inform the user of the availability of a plurality of different contents for downloading;

computer readable program means for causing a computer to receive from the user over a first a first communications link an indication of a desired content and a request for the desired content; and

computer readable program means for receiving from the user the at least one authentication key to indicate prepayment for the requested content;

computer readable program means for verifying the validity of the at least one authentication key by means of the validity database;

computer readable program means for causing a computer to provide the requested content to the user over a second communications link; and

computer readable program means for invalidating the at least one authentication key in the validity database in response to the providing of the requested content to the user.
