Electronic device possessing fingerprint identification system and its usage method

Abstract

The invention relate to an electronic device having a fingerprint identification system and a method of application thereof. The electronic device comprises a central processing unit which is respectively connected with a first memory unit and an input unit and used for controlling the operation of the electronic device; and a fingerprint sensing unit and a second memory unit, wherein the fingerprint sensing unit is used for scanning user's fingerprint, and the second memory unit is used for storing fingerprint identification images set by a user. Through the coordination of the device, a fingerprint image processing program and a fingerprint image identification program in advance stored in the electronic device are started, wherein the fingerprint image processing program is used for encrypting the fingerprint images scanned by the fingerprint sensing unit, or decrypting the encrypted fingerprint images read from the second memory unit, and the fingerprint image identification program is used for comparing the fingerprint images scanned by the fingerprint sensing unit and the preset decrypted fingerprint images, so as to determine whether the user is a legal user.

[0002] With the continuous advancement and development of science and technology, computers have become an indispensable part of modern people's lives, whether it is the management of documents, databases and files required for business operations, or the communication and games used by individuals for leisure It is precisely because of the increasing dependence of modern people on computers that the security of computer devices has become increasingly important. Therefore, the industry has developed a variety of measures to strengthen the security of computer devices. For example, by designing the fingerprint identification function to control the booting of the computer device and the division of authority, but the current computer device with the fingerprint identification function is to first store the user's fingerprint in a specific area of ​​the computer hard disk, and then if the user starts the computer Or when performing a certain operation, the fingerprint sensing unit of the computer scans the user's fingerprint to form a fingerprint image, and then the computer retrieves the fingerprint image pre-stored in the hard disk, and compares it with the scanned fingerprint image, such as If they are the same, the corresponding components of the computer are controlled to perform corresponding operations. Although this method can realize the confidentiality of computer data and the division of use rights to a certain extent, it still has the following disadvantages, that is, because the fingerprint image preset by the user is It is stored in the hard disk of the computer, so if the user or other borrowers accidentally delete the fingerprint image, the computer will not be able to find the pre-stored fingerprint image and perform corresponding operations when the computer is turned on next time, thus causing great harm to the user. troubled

On the other hand, the fingerprint image preset by the user is stored in the hard disk of the computer, and this part is not encrypted, so illegal users (such as hackers) can enter the fingerprint image through the network when the computer is in use. The computer, retrieve the fingerprint image in advance, and then use the fingerprint image to perform some illegal operations, which is not conducive to protecting the security of data in the computer device
