Abstract

The invention discloses a capacitance pen, which belongs to the technical field of digital signature. The capacitance pen comprises a Bluetooth communication module (101) and a control button (103), wherein the Bluetooth communication module (101) is communicated with a mobile terminal with a Bluetooth function and is connected with a data encryption module (102); and the control button (103) is used for controlling the Bluetooth communication module (101) to be started or closed. The capacitance pen has the advantages of being simple in structure and convenient in carrying, can realize data collection by a Bluetooth technology, carries out the digital signature on the collected data and improves the safety of data processing. In addition, the capacitance pen is also provided with a USB (Universal Serial Bus) interface and a memory chip or a USBKEY chip connected with the USB interface, and the capacitance pen can be used as a U type shield or the USBKEY; and the USB interface also can be connected with the data encryption module, and the digital signature of the data is realized through a USB connection way.

Description

technical field [0001] The invention relates to the technical field of digital signatures, in particular to a capacitive pen with a digital signature function. Background technique [0002] In the prior art, the capacitive touch screen works by utilizing the current induction of the human body. As we all know, a capacitive pen is a pen made of conductive material with conductive properties and used to touch a capacitive screen to complete man-machine dialogue operations. When the finger touches the metal layer, due to the electric field of the human body, the user and the surface of the touch screen form a coupling capacitance, for high-frequency current, the capacitance is a direct conductor, so the finger absorbs a very small current from the contact point. This current flows out of the electrodes on the four corners of the touch screen respectively, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners. ...
