Embodiment Construction

[0033] In order to describe the specific implementation of the present invention in detail, the following description is combined with the drawings:

[0034] Such as figure 1 As shown, a method for clearing fragmented data of an Android phone by scanning keywords includes the following steps:

[0035] S1: The user enters keyword information that exists in the data that he wants to be completely deleted, such as bank card account information in QQ chat records.

[0036] S2: Call the kernel function to get the data of the mobile phone partition, use the socket to communicate with the Android system, and get the data of the corresponding sector to the cache by sending commands. It should be noted here that the role of the Android system is only data transmission. Therefore, the restrictions of the Android system need to be shielded, and data can be written to realize the clearing of the underlying data.

[0037] S3: Analyze the file system of the mobile phone partition, distinguish the n...

Abstract

The invention discloses a method for clearing away fragment data of an Android phone by scanning keywords. The method comprises the following steps: S1 inputting keywords; S2 building connection; S3 analyzing mobile phone subregions; S4 scanning positions of keywords; S5 verifying data front and behind the keywords; S6 combining information front and behind the keywords; S7 displaying keywords information; S8 judging whether scanning is ended; and S9 screening and clearing away information. According to the method disclosed by the invention, a normal region, a free region and a fragment region in the subregions can be distinguished; the scanning region is shortened; to-be-deleted information is scanned and displayed through the keywords; the method is accurate and efficient, is capable of screening and clearing away fragment data, but cannot restore the data; the data privacy of public is ensured; and the malicious theft behavior aiming at private data is prevented.

Description

Technical field [0001] The invention relates to the technical field of information security, in particular to a method for clearing fragmented data of an Android mobile phone by scanning keywords. Background technique [0002] Android smart phones have an independent operating system, independent operating space, self-installing third-party software, powerful extensions, and are inseparable from people's lives. The mobile phone data information involves people's work, study, life, communication, finance, and leisure. , Entertainment, emotions, etc., are very precious intangible assets for individuals or companies. [0003] The Android system file management mechanism will cause fragmented data in the mobile phone memory and SD card, and during file management, the mobile phone memory and SD card will be defragmented. The fragments are most likely to contain user privacy data. Fragmented data can be recovered by some data recovery software on the market, leading to the disclosure o...
