Method for encrypting U disk data based on image password

Abstract

The invention discloses a method for encrypting U disk data based on an image password. The method comprises the following steps: (1) respectively arranging a graphical password input area, a graphical password storage module, a power supply module, an on-off key, a graphical password setting module, a graphical password obtaining module and a graphical password detection module on a U disk, wherein the password input area comprises a matts; the matts includes nine points, namely four vertexes on the matts, midpoints of four line segments and a central point; any adjacent points can be connected to form a pattern password; an antivirus module and a wireless communication module are arranged in the U disk; the wireless communication module is connected with a wireless network in an environment; and the antivirus module realizes virus reservoir upgrading via the wireless communication module; (2) setting the image password; (3) inputting the image password; and (4) detecting the image password. According to the method disclosed by the invention, the image password is taken as a verification method, and simultaneously the antivirus module is increased, so the security of the U disk is greatly improved; and in addition, the operation of the U disk is simpler and the use is more convenient.

Description

technical field [0001] The invention relates to a U disk, in particular to a method for encrypting U disk data based on an image password, and belongs to the technical field of electronic storage devices. Background technique [0002] With the progress of society and the development of technology, U disk has become an important choice for people to copy data due to its advantages of simple operation and portability. However, there are still many problems in the process of using U disk, for example: if If the U disk is stolen and a lot of important data is stored in it, the consequences will be unimaginable, and the important data of the U disk will be lost due to viruses and other reasons during use. No matter what the situation is, It will bring a lot of inconvenience to our work. At present, no effective solution has been proposed for the problem that the data in the U disk is easy to lose and the security is not high in the related technology. [0003] The Chinese invent...
