Embodiment Construction

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0046] see figure 1 , figure 1 It is the first flow chart of an SD card data security method provided by the embodiment of this application.

[0047] A kind of SD card data security method that the embodiment of the present application provides, can comprise the following steps:

[0048] Step S101: Determine the file system partition table of the target SD card.

[0049] In practical applications, the file system partition table of the target SD card may be determined first. Spe...

Abstract

The invention discloses an SD card data secrecy method, system and device and a computer medium. The method comprises the steps: determining a file system partition table of a target SD card; determining a target address in the target SD card, wherein the target address is an address except the block address 0 in the target SD card; and placing the file system partition table in the target address, and ensuring that the file system partition table is unique in the target SD card. According to the SD card data secrecy method, the file system partition table in the target SD card is placed in the target address except the block address 0, so that other hosts cannot read the file system partition table and cannot read files in the SD card under the condition that the target address is not known, and data security of the target SD card is realized. The SD card data secrecy system and device and the computer readable storage medium provided by the invention also solve the corresponding technical problems.

Description

technical field [0001] The present application relates to the technical field of data security, and more specifically, relates to an SD card data security method, system, device and computer medium. Background technique [0002] SD card is a new generation memory device based on semiconductor flash memory. Because SD card has excellent characteristics such as small size, fast data transmission speed, and hot-swappable, it is widely used in portable devices, such as digital cameras. , tablets and multimedia players and more. [0003] However, one SD card may be recognized by multiple devices, thereby making the data security of the SD card poor. [0004] To sum up, how to improve the data security of the SD card is an urgent problem to be solved by those skilled in the art. Contents of the invention [0005] The purpose of this application is to provide a SD card data security method, which can solve the technical problem of how to improve the data security of the SD card...
