Private cloud platform-based code composition analysis system and method

The invention discloses a private cloud platform-based code composition analysis system and method, and relates to the technical field of code safety analysis. According to the system and method, compositions of mixed source codes, such as open source codes, closed source codes, malicious codes and suspicious codes, are firstly recognized by using a code source mixing technology through online collecting construction code knowledge bases and knowledge maps by adoption of an automatic network collection technology on the basis of multitask parallel high-speed processing platform of private cloud calculation, and then the compositions are associated with code safety holes to realize quantitative assessment for code safety and construct a mixed source code composition quantitative analysis and assessment system, so that software code compositions can be correctly quantified, potential safety hazards of software can be decreased, intellectual property risks of the software can be discovered and autonomous level o
