Computer-implemented method and system for binding digital rights management executable code to a software application
View Patent ↗A computer-implemented method and system for binding digital rights management executable code to a software application are disclosed. The method and system include identifying a host code block in the host code section, copying the host code block from the host code section to a stub code block in the stub code section, and re-routing at least one reference of the host code block to be a reference of the stub code block.
1. A computer-implemented method, comprising:
executing a host code section;
identifying, during execution of the host code section, a host code block in the host code section;
categorizing, during execution of the host code section, the host code block by a function, wherein the function is performance sensitive or not performance sensitive; and
upon categorizing the host code block by the function as being not performance sensitive, processing the host code block, wherein processing the host code block includes:
copying, during execution of the host code section, the host code block from the host code section to a stub code block in a stub code section;
copying, during execution of the host code section, the stub code block to the host code block in the host code section;
re-routing at least one reference of the host code block to be a reference of the stub code block prior to termination of execution of the host code section; and
re-routing at least one reference of the stub code block to be a reference of the host code block prior to termination of execution of the host code section.
2. The computer-implemented method as claimed in claim 1 wherein the at least one reference of the host code block is an outbound reference.
3. The computer-implemented method as claimed in claim 1 wherein the at least one reference of the host code block is an inbound reference.
4. The computer-implemented method as claimed in claim 1 wherein the host code block in the host code section is rendered inoperable.
5. The computer-implemented method as claimed in claim 1 wherein the host code block in the host code section is identified by disassembling the host code section.
6. The computer-implemented method as claimed in claim 1 wherein the host code block in the host code section is identified by comparing host code blocks against a predefined list of functions.
7. The computer-implemented method as claimed in claim 1 wherein the host code block in the host code section is identified interactively during a wrapping process.
8. The computer-implemented method as claimed in claim 1 further including retaining at least one reference of the host code block to remain a reference of the host code block.
9. The computer-implemented method as claimed in claim 8 wherein the host code block in the host code section remains operable.
10. The computer-implemented method as claimed in claim 1 further comprising:
providing a stub routine in the stub code section;
re-routing at least one reference of the host code block to be a reference of the stub routine; and
re-routing at least one reference of the stub routine to be a reference of the stub code block.
11. The computer-implemented method as claimed in claim 10 wherein the at least one reference of the host code block is an outbound reference.
12. The computer-implemented method as claimed in claim 10 wherein the at least one reference of the host code block is an inbound reference.
13. The computer-implemented method as claimed in claim 10 wherein the stub routine is a digital rights management routine.
14. The computer-implemented method as claimed in claim 10 wherein the stub routine is an optical disc verification routine.
15. The computer-implemented method as claimed in claim 10 wherein the stub routine is an authentication verification routine.
16. The computer-implemented method as claimed in claim 10 wherein the stub routine is a tamper-proofing verification routine.
17. The computer-implemented method as claimed in claim 10 further including transforming the stub code block.
18. An article of manufacture embodied as a non-transitory computer-readable medium storing data that, when accessed by a machine, causes the machine to perform operations comprising:
executing a host code section;
identifying, during execution of the host code section, a host code block in the host code section;
categorizing, during execution of the host code section, the host code block by a function, wherein the function is performance sensitive or not performance sensitive; and
upon categorizing the host code block by the function as being not performance sensitive, processing the host code block, wherein processing the host code block includes:
copying, during execution of the host code section, the host code block from the host code section to a stub code block in a stub code section;
copying, during execution of the host code section, the stub code block to the host code block in the host code section;
re-routing at least one reference of the host code block to be a reference of the stub code block prior to termination of execution of the host code section; and
re-routing at least one reference of the stub code block to be a reference of the host code block prior to termination of execution of the host code section.
19. The article of manufacture as claimed in claim 18 wherein the at least one reference of the host code block is an outbound reference.
20. The article of manufacture as claimed in claim 18 wherein the at least one reference of the host code block is an inbound reference.
