Problems solved by technology
Since the current file fingerprint is generated based on the file content, the file content needs to be calculated, resulting in a relatively mechanized generated fingerprint. When the original file is slightly modified, the similarity of the file can be avoided or reduced, thereby circumventing the over the file protection system, resulting in reduced data security performance

The invention discloses a file category detection method and device, a storage medium and electronic equipment. The method comprises the steps of obtaining and preprocessing a to-be-detected file; extracting file category features from the preprocessed to-be-detected file; generating a file category fingerprint according to the file category feature; calculating file category similarity between the file category fingerprint and fingerprints in a preset file category fingerprint library; and determining the file category of the to-be-detected file according to the file category similarity. Therefore, by the embodiment of the invention, the category fingerprint of the to-be-detected file is generated by extracting the file category characteristics, and the category fingerprint is used as a protection basis for protecting the same category of files, so that the data security is improved.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a file type detection method, device, storage medium and electronic equipment. Background technique [0002] With the continuous development of informatization, the continuous extension of the network and the continuous upgrading of applications, the various tasks of governments at all levels and various types of enterprises gradually rely on computers and information systems, and the dependence on the network due to office informatization is becoming more and more obvious. At the same time, the increase in government and enterprise customer privacy, company sensitive data, financial and other confidential information, as well as the improvement of the information security supervision system of the country and various industries, are driving various organizations to have higher requirements for the security of sensitive data . As an important part of the data leakage preventio...
