firstly, reading source code file contents of various program languages, such as program languages of Html, css, javaScript, java, C, python and the like, acquiring all files of various program languages in a specified system according to file suffixes, reading text information of the source code files, and taking the text information as text information to be detected. And analyzing grammar and keywords which are possibly used for setting fonts according to different program language types, and identifying the fonts set in the source codes as first fonts by analyzing grammar characteristics and keyword usages from the text information to be detected. And comparing the first font with the purchased font list and the public free font list to judge whether the unauthorized font is used. If the unauthorized font is used, the file path, the file name and the file content related to infringement of the source code file using the unauthorized font are recorded.
Meanwhile, the system establishes a font classification model to identify the fonts of characters used by various picture resources by learning the characteristics of pictures containing purchased fonts and public free fonts based on a deep learning algorithm, judges whether unauthorized fonts are used or not, and records the paths and names of the pictures using the unauthorized fonts if the unauthorized fonts are used.
The result writing module 204: file information and picture information related to the use of the infringement font recorded by the infringement font checking module 203 are acquired and written into a result file.
