Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing:

[0021] like Figure 1-2 As shown, the smart U disk includes an external module and an internal module; the external module is composed of a USB interface; the internal module is composed of an analysis module, a comparison module, a sorting module and an erasing module; the analysis module, a comparison module, a sorting module and an erasing module The modules are connected to each other.

[0022] The method for erasing data from an intelligent U disk includes the following steps:

[0023] (1) Connect the U disk to the computer;

[0024] (2) Select the data to be copied in the computer;

[0025] (3) analyze the size of the copied data;

[0026] (4) analyze the size of the remaining capacity of the U disk;

[0027] (5) Judgment: If the remaining capacity is greater than the size of the copied data;

[0028] (6) Copying directly;

[0029] (7) Judgment: if the remainin...

Abstract

The invention provides an intelligent USB flash disk and a data wiping method and belongs to the technical field of electronic data wiping. The intelligent USB flash disk comprises an external module and an internal module, wherein the external module comprises a USB interface; the internal module comprises an analysis module, a comparison module, a sequencing module and a wiping module. The intelligent USB flash disk is novel in structure and adopts clear operation principle, the data copy time is effectively saved, and the work efficiency is improved to a certain degree.

Description

technical field [0001] The invention belongs to the technical field of electronic data erasure, and relates to an intelligent USB disk and a method for erasing data. Background technique [0002] With the development of computer technology, it is inevitable that the carrying of electronic data will be involved in life, study and work. U disk, as an electronic product for storing data, is small and easy to carry, large in storage capacity, cheap in price and reliable in performance. The advantages have won the favor of users. U-disk, full name "USB flash drive", English name "USB flash disk". It is a miniature high-capacity mobile storage product that uses a USB interface without a physical drive. It is connected to a computer through a USB interface to achieve plug and play; the U disk has many advantages: small and easy to carry, large storage capacity, cheap price, high performance Reliable, but the existing U-disk stores data and does not have the function of intelligen...
