Problems solved by technology

[0002] The existing external storage can be read and written as long as it is connected to the computer, without any read and write operations to control, because the manufacturer cannot directly control the hard disk flash memory chip, so the function of controllable operation cannot be completed, and in When the operation of external storage is realized, the intrusion of viruses cannot be well prevented; moreover, it does not have the function of data recovery for accidentally deleted files; it cannot effectively protect the data from reading and writing

Embodiment Construction

[0021] In order to make the purpose, technical solutions and advantages of the present invention clearer, the implementation of the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0022] This embodiment provides a method for implementing an external storage device with a digitally controllable function.

[0023] see figure 1 , the method includes the following steps:

[0024] Step 10 inputs different authorization commands and transmits the commands to the running unit;

[0025] Input different authorization commands in the digital authorization control device, and transmit the different authorization commands to different operating units in the external storage device; the authorization commands include three or more groups of digital identification codes, and the operating units include the main Control unit, read buffer unit and write buffer unit.

[0026] Step 20 starts the corresponding authorization function...

Abstract

The invention discloses a realization method of an external storage device with digital controllable function. The method comprises the steps that different authorisation commands are input in a digital authorisation control device, and the different authorisation commands are transmitted to different run units in the external storage device; the run units start corresponding authorisation functions of the external storage device according to the data information of the received authorisation commands. The storage device not only effectively prevents invasion of virus when mobile storage apparatuses exchange data, also protects the security of the stored information excellently.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for realizing an external storage device with a digitally controllable function. Background technique [0002] The existing external storage can be read and written as long as it is connected to the computer, without any read and write operations to control, because the manufacturer cannot directly control the hard disk flash memory chip, so the function of controllable operation cannot be completed, and in When the operation of external storage is realized, the intrusion of viruses cannot be well prevented; moreover, it does not have the function of data recovery for accidentally deleted files; it cannot effectively protect the data from reading and writing. Contents of the invention [0003] In order to solve the above-mentioned problems and defects, the present invention provides a realization method of an external storage device with a digitally controllable function. ...
