Abstract

In an example embodiment, a digital content distributor may transmit an unsigned license associated with a protected digital object to a digital rights management provider. The digital rights management provider may digitally sign the license and may transmit the signed license to the digital content distributor.

Claims

1. A method, comprising:

performing by one or more computers of a digital rights management provider;

providing an executable application to a user computing platform implemented on a computer system different than said one or more computers;

receiving an unsigned license associated with a protected digital object and further associated with a user computing platform from a content distributor, wherein the protected digital object is provided to the user computing platform by the content distributor, wherein the content distributor controls none of said one or more computers or said different computer system and the executable application provided to the user computing platform is configured to read the protected digital object contingent upon the signed license being received by the user computing platform; and

providing to the content distributor, a signed license associated with the protected digital object and destined for the executable application of the user computing platform.

2. The method of claim 1, the unsigned license comprising information identifying the user computing platform and an identification value associated with the protected digital object.

3. The method of claim 2, the identification value associated with the digital object to not include a title of the digital object to prevent an association of the title with the user computing platform.

4. The method of claim 1, the signed license comprising information identifying the user computing platform, information identifying the digital object, and a digital signature.

8. The article of claim 1, the signed license comprising information identifying the user computing platform, information identifying the digital object, and a digital signature.

5. An article, comprising:

a non-transitory storage medium having stored thereon instructions that, when executed on one or more computers of a digital rights management provider, are configured to;

provide an executable application to a user computing platform implemented on a computer system different than said one or more computers, the executable application provided to the user computing platform is configured to read the protected digital object contingent upon the signed license being received by the user computing platform;

receive an unsigned license associated with a protected digital object and further associated with a user computing platform from a content distributor, wherein the protected digital object is provided to the user computing platform by the content distributor, wherein the content distributor controls none of said one or more computers or said different computer system; and

provide to the content distributor, a signed license associated with the protected digital object and destined for the executable application of the user computing platform.

6. The article of claim 5, the unsigned license comprising information identifying the user computing platform and an identification value associated with the protected digital object.

7. The article of claim 6, the identification value associated with the digital object to not include a title of the digital object to prevent an association of the title with the user computing platform.
