specific Embodiment approach 1

[0022] The specific embodiment one, the portable electronic data erasing device based on U disk, it comprises: U disk;

[0023] It also includes an electronic data erasure system embedded in the USB flash drive; the electronic data erasure system includes:

[0024] Function library for storing information of various external disks and expansion cards;

[0025] It is used to identify the disk information of the external disk of the PC that the U disk is plugged into according to the information stored in the function library, and send the disk information to the storage medium identification module 1 of the display module 12;

[0026] It is used to scan the external disk of the PC connected to the U disk, obtain the used time and health status information of the disk, and send the used time and health status information to the storage information scanning module of the display module 12 4;

[0027] A data erasing module 9 for erasing data on the external disk of the PC connec...

specific Embodiment approach 2

[0032] Embodiment 2. The difference between this embodiment and the USB-based portable electronic data erasing device described in Embodiment 1 is that the disk information includes device type, disk capacity and index number.

specific Embodiment approach 3

[0033] Specific embodiment three, the difference between this specific embodiment and the portable electronic data erasing device based on U disk described in specific embodiment one is that, the mode that described data erasing module 9 erases the data in the disk is fast Erase method, BMB21-2007 standard erase method, DOD5220.22-M(8-306 / E) standard erase method or DOD 5220.22-M(8-306 / E,C and E) standard erase method.

[0034] This embodiment provides a variety of data erasing methods to meet the user's multi-angle erasing requirements; among them, the fast erasing mode is to perform a data erasing operation with a character of 0x00 on the largest data storage sector of the disk.

[0035] In addition to the data erasing method described in this embodiment, the user can also use a custom erasing method, which is a data erasing operation on any storage sector specified by the user in the disk, and the erasing character range is 0x00 -0xFF, the range of erase times is 0-99 times...

Abstract

The invention discloses a portable data wiping device based on a U disk, and relates to the electronic data wiping technology. The portable data wiping device solves the problems that an existing data wiping device is single in function and inconvenient to carry, and the operating result cannot be confirmed. The portable data wiping device comprises the U disk and an electronic data wiping system which is embedded into the U disk. The electronic data wiping system comprises a function library, a storage medium recognition module, a stored information scanning module, a data wiping module, a storage medium formatting module, a wiped information management module and a displaying module, wherein the storage medium recognition module is used for recognizing the disk information, the stored information scanning module is used for scanning the disk, the data wiping module is used for wiping the data, the storage medium formatting module is used for formatting the disk, the wiped information management module is used for recording and wiping the data and generating a data report, and the displaying module is used for displaying the received information on a displaying screen of a PC. The portable data wiping device is suitable for wiping the electronic data of various external disks.

Description

technical field [0001] The invention relates to a portable electronic data erasing device based on a USB disk, and relates to the field of electronic data erasure, in particular to the technical field of electronic data erasure based on a USB disk. Background technique [0002] Every year in our country, there are about several million disks that need to be eliminated due to damage, outdated and other reasons, and more U disks need to be destroyed. Such a large scale of destruction will inevitably cause unimaginable damage if effective management and technical means cannot be used. Consequences of disclosure. [0003] The data destruction technology born in the early 21st century is a symbol of the formation of a complete system in the field of confidential data information security. If "data recovery technology" is compared to the "spear" in the field of confidential data information security, then "data destruction technology" is a The "shield" in the field of confidentia...
