Abstract

The invention discloses a method and a device for scanning full disk data. The method comprises the following steps: performing format conversion on a scanned file to obtain a text object; performingtext objectification layering on the text object, the text objectification layering being used for constructing the text object into a single-layer text object to obtain a plurality of object layers of the text object; and based on the metadata of the scanning file, scanning the changed object layer in the plurality of object layers to obtain a scanning result. According to the method and the device, the technical problem of low data identification rate caused by low efficiency and poor cooperation capability of a full-disk sensitive data scanning mode generally adopted in a terminal data leakage prevention system in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of data security, in particular to a method and device for scanning data on an entire disk. Background technique [0002] At present, the terminal data leakage prevention system, as a traditional and mature data security tool, is gradually following the market demand and gradually developing in the direction of intelligence and collaboration to achieve higher protection efficiency and better protection effect. Mature terminal data leakage prevention systems have applied the full-disk sensitive data scanning function to identify sensitive attributes of local data in advance, reduce transmission or application delays caused by real-time scanning, and optimize user experience. The execution process of the full-disk sensitive data scanning function of the existing terminal data leakage prevention system is as follows: figure 1 As shown, different from the gateway-based sensitive data scanning, the full-scale scan...
