Abstract

The application provides a method and a device for rating private data based on big data, used to solve the problem of privacy data leakage that affects information security caused by missing classification and inaccurate rating of privacy data, and unable fast perception for the change of public sensitivity to private data in the prior art. The method comprises: extracting a plurality of high frequency keywords from the privacy data to be processed, and generating a high frequency word set by using the keyword whose word frequency is above a first preset threshold; determining a privacy classification of the privacy data to be processed based on the high frequency word set; establishing a high frequency word matrix based on the keyword having the frequency above the second preset threshold in the classified and rated private data in the collected big data; and rating the privacy data to be processed according to the high frequency word matrix and the privacy classification of the privacy data to be processed to obtain a privacy rating of the privacy data to be processed.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular, to a method and device for grading private data based on big data. Background technique [0002] With the development of Internet and big data technology, privacy data security has become one of the most concerned issues nowadays. The increasingly convenient data transmission can not only facilitate life, but also create huge production value. However, due to the convenience of data transmission, the private data in the data may also cause private information leakage during the transmission process, posing security risks. . Therefore, the protection of private data is getting more and more attention, and the classification and grading technology of private data based on big data is one of the key technologies of privacy protection. [0003] The current research on privacy data protection mainly focuses on the research on privacy attributes and their classificati...
