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:

determining whether a type of a verification target is a binary file type;

if the type of the verification target is a binary file type, obtaining a binary file and extracting a character string to be searched for from the obtained binary file;

determining whether the type of the verification target corresponds to a kernel module;

if the type of the verification target corresponds to the kernel module, obtaining the kernel module and extracting a character string to be searched for from the obtained kernel module separately; and

comparing the extracted character string from the obtained binary file and the obtained kernel module against a database 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 and a package file; and

extracting the binary file from at least one of the decompression and 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 obtained 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 database; and

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

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

6. 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.

7. The method of claim 1,

wherein the binary file is composed of binary data, and

wherein the obtained binary file may be one of an executable file and a library file stored in a storage unit.

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

9. A non-transitory computer readable storage medium storing a program causing at least one processor to perform license verification, the license verification comprising:

determining a type of a verification target;

if the type of the verification target is a binary file type, obtaining a binary file and extracting a character string to be searched for from the obtained binary file;

if the type of the verification target is a kernel module, obtaining a kernel module and extracting a character string to be searched for from the obtained kernel module separately; and

comparing the extracted character string from the obtained binary file and the obtained kernel module against a database created according to a license to be verified.

10. A license verification apparatus, the apparatus comprising:

an input unit configured to receive a license verification request; and

a control unit configured to;

determine a type of a verification target,

if the type of the verification target is a binary file type, obtain a binary file and extract a character string to be searched for from the obtained binary file;

if the type of the verification target is a kernel module, obtain the kernel module and extract a character string to be searched for from the obtained kernel module separately; and

compare the extracted character string from the obtained binary file and the obtained kernel module against a database created according to a license to be verified.

11. The apparatus of claim 10, wherein the control unit is further configured to:

identify 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 and a package file, and

extract the obtained binary file from the decompression, unpacking or decompilation results.

12. The apparatus of claim 10, wherein the control unit is further configured to extract the character string composed of representable characters from the obtained binary file.

13. The apparatus of claim 10, wherein the control unit is further configured to:

determine whether a character string matching the extracted character string is present in the database, and

determine, when the matching character string is present in the database, that the verification target corresponds to the license.

14. The apparatus of claim 10, further comprising a storage unit configured to storing store the database,

wherein the control unit is further configured to:

build the database containing at least one character string corresponding to the license to be verified, and

store the database in the storage unit.

15. The apparatus of claim 10, further comprising a display unit,

wherein the control unit is further configured to control 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.

16. The apparatus of claim 10,

wherein the obtained binary file is composed of binary data, and

wherein the obtained binary file is one of an executable file and library file stored in a storage unit.

17. The apparatus of claim 10, wherein the obtained binary file is disposed in a folder stored in a storage unit.
