Abstract

The invention discloses a fingerprint processing device as well as a control method and device thereof. The method comprises the following steps of: acquiring user fingerprint information through a first transmission channel; generating processing information according to the user fingerprint information; inquiring a preset communication link mark; transmitting the processing information to an upper computer through the first transmission channel when the inquired communication link mark is a first mark; encoding the processing information according to a keyboard character encoding mode when the inquired communication link mark is a second mark; and transmitting the encoded processing information to the upper machine through the second transmission channel, wherein the first transmission channel and the second transmission channel are different logic transmission channels on the same physical transmission channel. According to the invention, the fingerprint processing device not only can exchange data with a host computer which shields high-capacity storage-type USB (universal serial bus) interfaces, but also can exchange data with a host computer which only supports HID keyboard communication-type USB interfaces, and thus the communication mode between the fingerprint processing device and the upper machine is flexible.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint processing device, a control method and a control device thereof. Background technique [0002] With the development of fingerprint identification technology, the application of fingerprints is becoming more and more widespread, and more and more host computers are connected to fingerprint processing devices to complete user identity verification. At present, due to the relatively fast data transmission speed of the USB interface, the fingerprint processing device is generally connected to the host computer through the mass storage protocol of the USB port to complete the data transmission and reception with the host computer. [0003] However, in many applications, based on security needs, the host computer prohibits the use of mass storage protocols of the USB port, and only supports non-mass storage protocols, such as HID protocol and PC / SC pro...
