Abstract

The invention provides a document fingerprint construction method based on semantics, a storage medium and a computer device. Performing semantic analysis on the document data to obtain a plurality ofuseful words; generating A semantic fingerprint corresponding to the document data according to all the useful words. This method can protect electronic documents with similar semantics safely andeffectively, and reduce the risk of electronic document data disclosure.

Description

technical field [0001] The invention relates to the field of computer data security, in particular to a document fingerprint acquisition method, specifically a semantic-based document fingerprint construction method, a storage medium and a computer device. Background technique [0002] While electronic documents bring convenience to people in office, teaching and other work, there are also huge security risks. The security of electronic documents is more and more concerned by people. There are many important electronic documents that need to be protected in daily work and life, and the value of electronic documents will only be reflected in the process of use. Make full use of data under the premise of effective data protection , has become an urgent need of the people. [0003] Document Fingerprinting (Document Fingerprinting), also known as file fingerprinting, generates document fingerprints by extracting the characteristics of files, and can complete the protection of i...
