Abstract
The present subject matter relates to a device for digital rights management. The device includes a classification module that assigns a classification tag to a document. The classification tag is selected from a predefined classification scheme. Further, the device includes an access control module that checks a lock status of the document at a predefined time interval. The predefined time interval depends on the classification tag of the document. Further, the access control module locks the document based on the lock status.
Claims20
A method for controlling access to a protected document, the method comprising:
- monitoring of a lock status of the protected document, wherein the protected document is assigned with a classification tag from a predefined classification scheme, and wherein the monitoring of the lock status is based on the classification tag;
- and
- locking the document based on the lock status.
A device comprising:
- a processor;
- and
- a memory coupled to the processor, the memory comprising:
- a classification module configured to assign a classification tag to a document, wherein the classification tag is selected for the document from a predefined classification scheme;
- and
- an access control module configured to:
- check a lock status of the document at a predefined time interval, wherein the predefined time interval is based on the classification tag of the document;
- and
- lock the document based on the lock status.
A computer-readable medium having computer-executable instructions that when executed perform acts comprising:
- assigning a classification tag to a document, wherein the classification tag is selected for the document from a predefined classification scheme;
- checking a lock status of the document at a predefined time interval, wherein the predefined time interval is based on the classification tag;
- locking the document based on the lock status.
