Description

technical field

[0001] The invention belongs to the technical field of mobile terminals, and in particular relates to a method for constructing and updating a storage medium feature database. Background technique

[0002] The upgrading speed of electronic products such as mobile terminal equipment and computers is gradually accelerating. According to statistics, as of October 2015, my country's mobile phone users have reached 1.302 billion, and there are about 200 million discarded mobile phones produced every year, but the recycling rate is still less than 1% [1]. One of the reasons is that trading users are worried about waste mobile phones. The private information inside is leaked. Usually, the information deletion or formatting functions of these electronic devices cannot really clear the data information stored on these storage media, and some or all of the data can be recovered by using non-professional processing of special software [2], This poses a serious threat t...

Examples

Embodiment Construction

[0019] The invention proposes a construction and update method of a storage medium feature database, which includes a storage medium feature data case building module, a waste electronic equipment hardware scanning and feature identification module, a feature data comparison and matching module, an unknown case extraction module, an unknown Case update modules such as figure 1 shown.

[0020] (1) Feature data case building blocks

[0021] The input of this module is storage media or existing waste electronic equipment, and the output is feature set model and feature data. According to the hardware parameters and other information of different types of storage media collected offline, different standard feature set models are constructed, and the collection and management of storage medium feature data cases are carried out based on this, and then information is collected for different waste electronic equipment based on the collected information. Clearing experiments, to stu...
