Abstract

A method and apparatus for verifying licenses of binary files and to a computer readable storage medium storing a program realizing license verification is provided. The method includes obtaining a binary file, extracting a character string to be searched for from the obtained binary file, and comparing the extracted character string against a knowledge base created according to a license to be verified, an apparatus capable of executing the license verification method, and a computer readable storage medium storing a program realizing the license verification method.

Claims

1. A license verification method, the method comprising:

obtaining a binary file;

extracting a character string to be searched for from the obtained binary file; and

comparing the extracted character string against a knowledge base created according to a license to be verified.

2. The method of claim 1, wherein the obtaining of the binary file comprises:

identifying a type of a verification target;

performing at least one of decompressing, unpacking and decompiling the verification target when the verification target type is at least one of a compressed file or a package file; and

extracting the binary file from at least one of the decompression or decompilation results.

3. The method of claim 1, wherein the extracting of the character string to be searched comprises extracting at least one character string from the binary file.

4. The method of claim 1, wherein the comparing of the extracted character string comprises:

determining whether a character string matching the extracted character string is present in the knowledge base; and

determining, when the character string matching the extracted character string is present in the knowledge base, that the extracted character string corresponds to the license.

5. The method of claim 1, further comprising determining whether the binary file corresponds to the license according to the character string check result.

6. The method of claim 1, further comprising building the knowledge base containing at least one character string corresponding to the license to be verified.

7. The method of claim 1, further comprising displaying at least one of information on the obtained binary file, information on the extracted character string, verification status information, and verification results.

8. The method of claim 1, wherein the binary file is composed of binary data, and

wherein the binary file may be an executable file or library file stored on a storage unit.

9. The method of claim 1, wherein the binary file is disposed in a folder stored on a storage unit.

10. The method of claim 1, wherein the comparing of the extracted character string comprises determining whether the extracted character string corresponds to a kernel module.

11. A non-transitory computer readable storage medium storing a program that, when executed, cause at least one processor to perform the method of claim 1.

12. A license verification apparatus, the apparatus comprising:

an input unit receiving a license verification request; and

a control unit obtaining, upon reception of the license verification request, a binary file, extracting a character string to be searched for from the obtained binary file, and comparing the extracted character string against a knowledge base created according to a license to be verified.

13. The apparatus of claim 12, wherein the control unit identifies the type of a verification target,

wherein the control unit decompresses, unpacks or decompiles the verification target when the verification target type is at least one of a compressed file or a package file, and

wherein the controller extracts the binary file from the decompression, unpacking or decompilation results.

14. The apparatus of claim 12, wherein the control unit extracts the character string composed of representable characters from the binary file.

15. The apparatus of claim 12, wherein the control unit determines whether a character string matching the extracted character string is present in the knowledge base, and

wherein the controller determines, when the matching character string is present in the knowledge base, that the verification target corresponds to the license.

16. The apparatus of claim 12, wherein the control unit determines whether the binary file corresponds to the license according to the character string check result.

17. The apparatus of claim 12, further comprising a storage unit storing the knowledge base,

wherein the control unit builds the knowledge base containing at least one character string corresponding to the license to be verified and stores the knowledge base in the storage unit.

18. The apparatus of claim 12, further comprising a display unit, wherein the control unit controls the display unit to display at least one of information on the obtained binary file, information on the extracted character string, verification status information, and verification results.

19. The apparatus of claim 12, wherein the binary file is composed of binary data, and

wherein the binary file may be an executable file or library file stored on a storage unit.

20. The apparatus of claim 12, wherein the binary file is disposed in a folder stored on a storage unit.
