Embodiment Construction

[0037] In order to describe the specific embodiment of the present invention in detail, below in conjunction with accompanying drawing to illustrate:

[0038] Such as figure 1 As shown, S1: enable Android underlying services;

[0039] S2: analyze the file system of the partition;

[0040] S3: Clear all fragmented data in the free area;

[0041] S4: Clear all fragmented data in the normal area.

[0042] Such as figure 2 As shown, the S1 includes the following steps:

[0043] S101: Shield the restrictions of the Android system; the function of the Android system is only for data transmission, so the restrictions of the Android system are blocked to realize the removal of underlying data.

[0044] S102: Call the underlying interface to obtain the data of the mobile phone partition with a custom block size;

[0045] S103: The mobile phone is used as the server, and the PC is used as the client, using the Android ADB Socket to establish communication with the Android system;...

Abstract

The invention discloses a method of clearing fragmented data of Android phone. The method comprises the following steps: S1, starting an Android underlying service; S2, paring file systems of partitions; S3, clearing all fragmented data of idle areas; S4, clearing all fragmented data of normal areas; The method of clearing fragmented data of Android phone is able to distinguish normal areas, idle areas and fragmented areas in partitions, thoroughly clear all fragmented data in idle areas and data of the fragmented areas in the normal areas, thereby ensuring data privacy of the public, and preventing baleful stealing of privacy data.

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. Background technique [0002] Android smartphones have an independent operating system, independent operating space, and can install third-party software by themselves. They have powerful expansion functions and are inseparable from people's lives. The mobile phone data information involves people's work, study, life, communication, finance, leisure. , entertainment, emotions, etc., are very precious intangible assets for individuals or companies. [0003] The file management mechanism of the Android system will lead to fragmented data in the phone's memory and SD card, and when performing file management, the phone's memory and SD card will be defragmented, and the fragments are likely to contain the user's private data. Fragmented data can be recovered by some data recovery software on the market, r...
