View Patent ↗Briefly, in accordance with one or more embodiments, a utilization permit key may be pre-defined to permit at least one of displaying, editing, storing, copying, and/or transferring of digital data.
1. A method, comprising:
receiving a utilization permit key at a computing device;
decrypting encrypted data to produce decrypted data, wherein the decrypting is performed by the computing device using the utilization permit key;
determining, based at least in part on the utilization permit key, a set of permitted operations;
receiving a request for a specified operation;
in response to determining that the set of permitted operations does not include the specified operation, preventing the specified operation.
2. The method of claim 1 , wherein determining that the set of permitted operations does not include the specified operation is based on a number of times that the specified operation has previously been performed.
3. The method of claim 1 , wherein decrypting the encrypted data to produce decrypted data includes:
determining a number of times that the utilization permit key has previously been used; and
determining that the number of times that the utilization permit key has previously been used is less than a key usage limit.
4. The method of claim 3 , wherein the key usage limit is one usage.
5. The method of claim 1 , wherein the determining that the set of permitted operations does not include the specified operation includes determining that permitting the specified operation would result in the specified operation being performed more times than a specified limit.
6. The method of claim 1 , wherein the set of permitted operations includes a plurality of permitted types of operations.
7. The method of claim 1 , wherein the set of permitted operations comprises one or more operations selected from the set consisting of displaying, storing, copying, editing, and transferring.
8. The method of claim 1 , wherein the set of permitted operations consists of one type of operation, wherein the one type of operation is selected from the set consisting of displaying, storing, copying, editing, and transferring.
9. An article of manufacture including a non-transitory computer-readable memory medium having program instructions stored thereon that, responsive to execution by a computer system, cause the computer system to perform operations comprising:
receiving a utilization permit key;
decrypting encrypted data to produce decrypted data, wherein the decrypting is performed using the utilization permit key;
determining, based at least in part on the utilization permit key, a set of permitted operations;
receiving a request for a specified operation;
in response to determining that the set of permitted operations does not include the specified operation, preventing the specified operation.
10. The article of manufacture of claim 9 , wherein determining that the set of permitted operations does not include the specified operation is based on a number of times that the specified operation has previously been performed.
11. The article of manufacture of claim 9 , wherein decrypting the encrypted data to produce decrypted data includes:
determining a number of times that the utilization permit key has previously been used; and
determining that the number of times that the utilization permit key has previously been used is less than a key usage limit.
12. The article of manufacture of claim 11 , the operations further comprising:
adjusting the utilization permit key to indicate additional usage to decrypt data.
13. The article of manufacture of claim 9 , wherein the set of permitted operations includes a plurality of permitted operations.
14. The article of manufacture of claim 9 , wherein the set of permitted operations consists of one operation, wherein the one operation is selected from the set consisting of displaying, storing, copying, editing, and transferring.
15. An apparatus, comprising:
a processor;
memory, coupled to the processor, having stored thereon program instructions executable to cause the apparatus to perform operations comprising:
receiving a utilization permit key;
decrypting encrypted data to produce decrypted data, wherein the decrypting is performed by using the utilization permit key;
determining, based at least in part on the utilization permit key, a set of permitted operations;
receiving a request for a specified operation;
in response to determining that the set of permitted operations does not include the specified operation, preventing the specified operation.
16. The apparatus of claim 15 , wherein determining that the set of permitted operations does not include the specified operation is based on a number of times that the specified operation has previously been performed.
17. The apparatus of claim 15 , wherein decrypting the encrypted data to produce decrypted data includes:
determining a number of times that the utilization permit key has previously been used; and
determining that the number of times that the utilization permit key has previously been used is less than a key usage limit.
18. The apparatus of claim 17 , the operations further comprising:
adjusting the utilization permit key to indicate additional usage.
19. The apparatus of claim 15 , wherein the set of permitted operations includes a plurality of permitted operations.
20. The apparatus of claim 15 , wherein the set of permitted operations consists of one operation, wherein the one operation is selected from the set consisting of displaying, storing, copying, editing, and transferring.
