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.
Claims19
A method for controlling access to a protected document for a user on a computing device having a processor, the method comprising:
- assigning, by the processor, a classification tag to the protected document, wherein the classification tag is assigned from a predefined classification scheme, the classification tag representing a level of sensitivity of contents in the protected document;
- monitoring, by the processor, a lock status of the protected document, wherein the lock status of the protected document is “Not_Locked” by default, and wherein the monitoring comprises checking the lock status of the protected document at a predefined time interval, wherein the predefined time interval is based on the classification tag assigned to the protected document;
- and
- locking the protected document, by the processor, when one of an owner of the protected document and an administrator changes the lock status of the protected document from “Not_Locked” to “Locked”.
A computing device for controlling access to a protected document for a user, the computing device comprising:
- a processor;
- and
- a memory coupled to the processor, the memory comprising:
- a classification module, stored in the memory and executable by the processor to assign a classification tag to the protected document, wherein the classification tag is selected for the protected document from a predefined classification scheme, the classification tag representing a level of sensitivity of contents in the protected document;
- and
- an access control module, stored in the memory and executable by the processor to:
- check a lock status of the protected document at a predefined time interval, wherein the lock status of the protected document is “Not_Locked” by default, and wherein the predefined time interval is based on the classification tag of the protected document;
- and
- lock the protected document when one of an owner of the protected document and an administrator changes the lock status of the protected document from “Not_Locked” to “Locked”.
A non-transitory computer-readable medium having computer-executable instructions that when executed perform acts comprising:
- assigning a classification tag to a protected document, wherein the classification tag is selected for the protected document from a predefined classification scheme, the classification tag representing a level of sensitivity of contents in the protected document;
- checking a lock status of the protected document at a predefined time interval, wherein the protected document has a lock status of “Not_Locked” by default, and wherein the predefined time interval is based on the classification tag assigned to the protected document;
- and
- locking the protected document when one of an owner of the protected document and an administrator changes the lock status of the protected document from “Not_Locked” to “Locked”.
