Software birthmarks have been proposed as a method for enabling the detection of programs that may have been stolen by measuring the similarity between the two programs. A birthmark is created from each program by extracting its native characteristics. The birthmarks of the programs can then be compared. However, the existing software birthmark is mainly software birthmark single attribute, they will play a good effect in the specific scene, but poor robustness in general single attribute software. For a single attribute of software birthmark has poor robustness, resistance to attack ability is not strong, multi attribute extraction software birthmark from point of view, this paper firstly proposed Java software related attribute analysis of hierarchical structure, on the basis of a multi attribute static software birthmark.
