Description

Miniature electronic lock device

The present invention relates to an electronic lock, especially a miniature electronic lock device that can be used in a computer device and can detect fingerprints.

In recent years, security management applied to computers has gradually received attention, among which fingerprint recognition is a common security management technology.

There are already some portable computer devices on the market that are equipped with fingerprint recognition components to confirm the user's identity and manage the control authority of the portable computer device to prevent the data in the portable computer device from being stolen, but beware When a person wants to steal a portable computer device, the portable computer device or fingerprint recognition element cannot actively send out an alarm, and cannot achieve the deterrent effect of preventing theft.

In addition, not every computer device is equipped with a fingerprint recognition component. Therefore, a computer device without a fingerprint recognition component cannot perform security management and cannot recognize the user's identity to further manage the control authority of the computer device.

The Republic of China Patent No. M535863 describes a flash drive with identification function, which can provide fingerprint identification function to control the reading and writing authority of the data in the flash drive, but the identification function flash drive itself analyzes fingerprints and does not check the computer device. Provides control authority to control, so the computer device itself does not have the function of fingerprint recognition, and the recognition function of the flash drive will lose power and cannot operate after it leaves the computer device.

Although the conventional technology discloses a fingerprint recognition device that can be carried around, it still has the following shortcomings in actual use:

1. No theft prevention:

Generally, a security element that can be carried around and can recognize fingerprints can only provide operating permissions for computer devices, but it cannot send out an alarm by itself, and cannot achieve the effect of deterring theft.

2. Cannot operate alone:

Generally, the fingerprint-recognizable security element can only be inserted into the computer device to operate, and then provide the control of the operating authority of the computer device. When the fingerprint-recognizable security element is separated from the computer device, the recognizable security element The fingerprint's security element loses power and cannot operate.

3. Unable to actively notify:

At present, the fingerprint-recognizable security element only provides the control of operation authority, and cannot actively send alarm information to another computer device or communication device, and cannot achieve the effect of actively notifying and reporting information.

Therefore, in addition to the basic functions of fingerprint detection and operation authority control, how to actively send out alarm information to deter computer devices from being stolen, and to actively notify the configured communication device is an urgent need for relevant technicians.
