AI Technical Summary

Problems solved by technology

Due to the large amount of manual intervention required, it is prone to missed detections
In addition, when searching for any possible identity identifier, the entire hard disk data must be traversed again, resulting in a very time-consuming process of obtaining evidence, which is not convenient for multiple searches

Abstract

The invention belongs to the technical field of information identification, and particularly relates to a method and a device for extracting an identity label. The method comprises the following steps: S1) converting the user trace of a user and a document file in a computer into a pure text format; S2) retrieving identity label information in the pure text; and S3) calculating the occurrence frequencies of the retrieved identity label information. The traditional problem of long time consumption for extracting identity label information is solved, and the identity label information which frequently appears can be conveniently and quickly positioned. In addition, the text can be quickly searched independently so as to shorten evidence obtaining time and improve efficiency.

Description

technical field [0001] The invention belongs to the technical field of information identification, and in particular relates to a method and device for extracting an identity mark. Background technique [0002] With the development of society, the consumption of electronic equipment is increasing rapidly. Electronic equipment has become an indispensable item in people's life. The forensics of electronic equipment has naturally become the focus of the field of forensics. But now the hard disk capacity of the device is gradually increasing, and the data file format in the hard disk is becoming more and more complicated, and the number is increasing. Faced with so many different formats and a large number of data files, how to quickly retrieve effective identification information has become a focus of forensics products. [0003] Reference patent document CN103500216A discloses a method for extracting file information, including: obtaining file information sequentially in para...
