Abstract

A dynamic multimedia fingerprinting system is provided. A user requests multimedia content from a Web cache server that verifies that the user is authorized to download the content. A custom fingerprint specific to the user is generated and dynamically inserted into the content as the content is delivered to the user. The custom fingerprint can be generated on the Web cache server or at the content provider'"'"'s server. The system allows a content provider to specify where the custom fingerprint is inserted into the content or where the fingerprint is to replace a placeholder within the content.

Claims

1. A method for performing dynamic fingerprinting of multimedia content, comprising:

receiving a user request for a specific multimedia content at a server;

delivering the specific multimedia content to the user from the server; and

wherein the delivering step inserts a custom fingerprint in a location within the specific multimedia content while delivering the specific multimedia content to the user, the custom fingerprint containing information pertaining to the user.

2. The method of claim 1, wherein the location is configurable by a content provider and/or administrator.

3. The method of claim 1, wherein the delivering step replaces a placeholder in the specific multimedia content with the custom fingerprint.

4. The method of claim 1, wherein the delivering step is configured to either obtain the custom fingerprint from a content provider'"'"'s server or create the custom fingerprint locally on the server depending upon the type of content requested.

5. An apparatus for performing dynamic fingerprinting of multimedia content, comprising:

a server that receives a user request for a specific multimedia content;

a content delivery subsystem that delivers the specific multimedia content to the user from the server; and

wherein the content delivery subsystem inserts a custom fingerprint in a location within the specific multimedia content while delivering the specific multimedia content to the user, the custom fingerprint containing information pertaining to the user.

6. The apparatus of claim 5, wherein the location is configurable by a content provider and/or administrator.

7. The apparatus of claim 5, wherein the content delivery subsystem replaces a placeholder in the specific multimedia content with the custom fingerprint.

8. The apparatus of claim 5, wherein the content delivery subsystem is configured to either obtain the custom fingerprint from the content provider'"'"'s server or create the custom fingerprint locally on the server depending upon the type of content requested.

9. A computer-readable medium carrying one or more sequences of instructions for performing dynamic fingerprinting of multimedia content, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform steps comprising:

receiving a user request for a specific multimedia content at a server;

delivering the specific multimedia content to the user from the server; and

wherein the delivering step inserts a custom fingerprint in a location within the specific multimedia content while delivering the specific multimedia content to the user, the custom fingerprint containing information pertaining to the user.

10. The machine-readable medium of claim 9, wherein the location is configurable by the content provider and/or administrator.

11. The machine-readable medium of claim 9, wherein the delivering step replaces a placeholder in the specific multimedia content with the custom fingerprint.

12. The machine-readable medium of claim 9, wherein the delivering step is configured to either obtain the custom fingerprint from the content provider'"'"'s server or create the custom fingerprint locally on the server depending upon the type of content requested.
