Digital content rights management method and system
First Claim
1. A digital content rights management method comprising:
- generating a time stamp, by a device including a program for accessing a digital content, wherein the time stamp includes time information of the device;
when the program for accessing the digital content starts up, verifying validity of the time stamp, wherein if the verification passes, performing a next step and if the verification fails, disallowing the access of the digital content;
acquiring a certificate of authorization for accessing the digital content, wherein the certificate of authorization specifies a starting time and an ending time of allowing to access the digital content; and
verifying a time of the device with the time stamp and the certificate of authorization to determine whether the device is allowed to access the digital content.

Abstract
A digital content rights management method and system belongs to the digital content rights management technique field. The method of the invention includes the steps: registering the system, generating the time stamp, verifying the time stamp when the system starts up, acquiring the certificate, verifying the time before accessing the digital content. The system of the invention comprises a device for accessing the digital content and a server, wherein the device for accessing the digital content comprises: a registering module, a time stamp generating module, a time stamp verification module, a certificate of authorization acquiring module, and a time verification module. The method and system have solved the problem that the digital content can still be used beyond the time limit.
