Abstract

The invention provides a data deleting method, a data deleting device and a terminal, wherein the data deleting method comprises the following steps that when the condition that an operation system of a terminal receives a data deleting request is detected, specified external equipment is selected from at least one piece of external equipment connected with the terminal according to the data deleting request; the information of data requested to be deleted by the data deleting request is sent to the specified external equipment; according to the data information and preset conditions, whether the data information meets the preset conditions or not is judged in the specified external equipment; a judging result is sent to the operation system so that the operation system processes the data according to the judging result. According to the technical scheme, the wrong deletion of the data by the operation system can be avoided, and the data security is improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a data deletion method, a data deletion device and a terminal. Background technique [0002] In the operating system of the terminal, especially in the security system of the dual-system terminal, there are no conditions for the deletion operation, and the deletion operation is directly completed by the operating system of the terminal. However, it is very easy to directly delete important content when a misoperation occurs in this way, which causes great inconvenience to the terminal user. [0003] Therefore, a new technical solution is needed, which can prevent the operating system of the terminal from deleting data by mistake. Contents of the invention [0004] Based on the above problems, the present invention proposes a new technical solution, which can prevent the operating system of the terminal from deleting data by mistake. [0005] In view of this, the pre...
