Abstract

A comparison system includes a memory including a first compiled version and a second compiled version of a target application, at least one processor, and a comparison engine, executing on the at least one processor. The comparison engine is configured to identify a method in the first compiled version, locate the method in the second compiled version, compare the method in the first compiled version to the method in the second compiled version, and providing an indication that the method is an altered method from the first compiled version to the second compiled version of the target application.

First claim

What is claimed is:

1. A comparison system comprising:
a memory storing a first compiled version and a second compiled version of a target application;
one or more hardware processors; and
a comparison engine comprising instructions that, when executed on at least one of the one or more hardware processors, cause the comparison engine to perform operations comprising:
accessing the memory and identifying a method in the first compiled version;
locating the method in the second compiled version;
comparing the method in the first compiled version to the method in the second compiled version to determine whether the method in the first compiled version is different from the method in the second compiled version,
the comparing of the method in the first compiled version to the method in the second compiled version comprising comparing a structure of the method in the first compiled version to a structure of the method in the second compiled version; and
based on a determination that the method in the first compiled version is different from the method in the second compiled version, causing display of an indication that the method is changed from the first compiled version to the second compiled version of the target application.

2. The comparison system of claim 1 , wherein the operations further comprise:
generating a first structure signature based on the structure of the method in the first compiled version; and
generating a second structure signature based on the structure of the method in the second compiled version,
wherein comparing the structure of the method in the first compiled version to the structure of the method in the second compiled version comprises comparing the first structure signature to the second structure signature.

3. The comparison system of claim 1 , wherein comparing the method in the first compiled version to the method in the second compiled version further comprises comparing operations in the method in the first compiled version to operations in the method in the second compiled version.

4. The comparison system of claim 3 , wherein the operations further comprise:
generating a first operations signature based on the operations in the method in the first compiled version; and
generating a second operations signature based on the operations in the method in the second compiled version,
wherein comparing the operations in the method in the first compiled version to the operations in the method in the second compiled version comprises comparing the first operations signature to the second operations signature.

5. The comparison system of claim 1 , further comprising:
a compiler,
wherein the operations further comprise initiating compilation of at least one of a first source code and a second source code of the target application using the compiler, thereby generating at least one of the first compiled version and the second compiled version.

6. The comparison system of claim 1 , wherein the memory further stores a source database storing at least one of the first compiled version and the second compiled version; and
wherein the operations further comprising comprise retrieving the at least one of the first compiled version and the second compiled version from the source database prior to the comparing of the method in the first compiled version to the method in the second compiled version.

7. A computerized method comprising:
identifying, in a memory, a method in a first compiled version of a target application;
locating, in the memory, the method in a second compiled version of the target application;
comparing, by at least one hardware processor, the method in the first compiled version to the method in the second compiled version to determine whether the method in the first compiled version is different from the method in the second compiled version,
the comparing of the method in the first compiled version to the method in the second compiled version comprising comparing a structure of the method in the first compiled version to a structure of the method in the second compiled version; and
based on a determination that the method in the first compiled version is different from the method in the second compiled version, causing display of an indication that the method is changed from the first compiled version to the second compiled version of the target application.

8. The computerized method of claim 7 , further comprising:
generating a first structure signature based on the structure of the method in the first compiled version; and
generating a second structure signature based on the structure of the method in the second compiled version,
wherein comparing the structure of the method in the first compiled version to the structure of the method in the second compiled version comprises comparing the first structure signature to the second structure signature.

9. The computerized method of claim 7 , wherein comparing the method in the first compiled version to the method in the second compiled version comprises comparing operations in the method in the first compiled version to operations in the method in the second compiled version.

10. The computerized method of claim 9 , further comprising:
generating a first operations signature based on the operations in the method in the first compiled version; and
generating a second operations signature based on the operations in the method in the second compiled version,
wherein comparing the operations in the method in the first compiled version to the operations in the method in the second compiled version comprises comparing the first operations signature to the second operations signature.

11. The computerized method of claim 7 , further comprising initiating compilation of at least one of a first source code and a second source code of the target application using a compiler, thereby generating at least one of the first compiled version and the second compiled version.

12. The computerized method of claim 7 , further comprising retrieving at least one of the first compiled version and the second compiled version from a source database prior to the comparing of the method in the first compiled version to the method in the second compiled version.

13. A non-transitory machine-readable medium storing processor-executable instructions that, when executed by at least one hardware processor of a machine, cause the machine to perform operations comprising:
identifying a method in a first compiled version of a target application;
locate locating the method in a second compiled version of the target application;
comparing the method in the first compiled version to the method in the second compiled version to determine whether the method in the first compiled version is different from the method in the second compiled version,
the comparing of the method in the first compiled version to the method in the second compiled version comprising comparing a structure of the method in the first compiled version to a structure of the method in the second compiled version; and
based on a determination that the method in the first compiled version is different from the method in the second compiled version, causing display of an indication that the method is changed from the first compiled version to the second compiled version of the target application.

14. The machine-readable medium of claim 13 , wherein the operations further comprise:
generating a first structure signature based on the structure of the method in the first compiled version; and
generating a second structure signature based on the structure of the method in the seco
