[0016] The present utility model will be further described in detail below in conjunction with the embodiments and the drawings, but the embodiments of the present utility model are not limited thereto.
[0017] The specific implementation process of the present utility model is as follows:
[0018] As shown in Figure 1 , an electromagnetic pen with an identity recognition function is used in combination with an electromagnetic screen, and includes a pen barrel, an electromagnetic induction head, a PCB board, a microprocessor, and a fingerprint recognition module. The electromagnetic induction head is arranged at the bottom end of the pen barrel, the PCB board is clamped inside the pen barrel, the microprocessor is arranged on the PCB board, the fingerprint recognition module is integrated on the outer surface of the pen barrel, the electromagnetic induction head and the fingerprint recognition module are respectively electrically connected to the microprocessor, and the microprocessor is used to receive and process the electromagnetic signals interacted between the electromagnetic induction head and the electromagnetic screen and the fingerprint data of the fingerprint recognition module.
[0019] In an embodiment of the present utility model, the fingerprint recognition module is a capacitive fingerprint recognition sensor with high sensitivity and low power consumption, which is installed on the outer surface of the pen body of the pen rod, or can also be installed at a position convenient for contact such as the pen cap, facilitating quick identity verification before the user picks up or uses the electromagnetic pen. The capacitive induction technology is adopted to capture and recognize the texture features of the user's fingerprint. Specifically, when the user holds the pen, the fingerprint recognition module integrated on the outer surface of the pen rod or at the pen cap will collect the user's fingerprint information, that is, capture the fingerprint image. The fingerprint recognition module sends the collected fingerprint image to the microprocessor for digital processing to form fingerprint data, and then transmits the fingerprint data to the paperless business system. The paperless business system compares and analyzes the fingerprint data with the fingerprint data of the pre-stored legitimate users through the fingerprint recognition algorithm. When the fingerprint data matches the fingerprint stored in the system, the verification is passed and the user's identity is confirmed.
[0020] The electromagnetic induction head interacts with the electromagnetic screen. That is, when the user writes on the electromagnetic screen with the electromagnetic pen, the induction coil in the electromagnetic pen will sense the magnetic field change emitted by the electromagnetic screen. As the electromagnetic pen moves, the induction circuit inside it will generate corresponding electrical signals, and these signals are processed and converted into the pressure-sensitive data and coordinate data of the handwriting. The pressure-sensitive data of the handwriting is the change in the writing force during the writing process of the user; the coordinate data is the specific position and movement trajectory of the electromagnetic pen on the electromagnetic screen. The pressure-sensitive data and coordinate data are integrated to generate signature handwriting data, which completely records the writing process and signature style of the user. The signature handwriting data and the user's fingerprint data are submitted to the paperless business system together and stored in the storage unit for subsequent inspection and verification.
[0021] In an embodiment of the present utility model, the electromagnetic pen further includes an encryption chip, which is electrically connected to the microprocessor and is used to encrypt the data processed by the microprocessor to prevent illegal access.
[0022] In an embodiment of the present utility model, the electromagnetic pen further includes a rechargeable battery, which is electrically connected to the PCB board and is used to provide power for the electromagnetic pen. It can also adopt the power supply method of externally connecting a power cord, and the battery power supply for providing power can be set according to actual usage requirements.
[0023] The utility model integrates a fingerprint recognition module, a PCB board and a microprocessor on an electromagnetic pen. The fingerprint recognition module collects fingerprint data of the operator of the electromagnetic pen. The electromagnetic induction head of the electromagnetic pen interacts with the electromagnetic screen to obtain signature handwriting data. The fingerprint data and the signature handwriting data are processed and analyzed by the microprocessor and then stored in a paperless business system for confirming the identity of the operator of the electromagnetic pen. It realizes identity authentication during the writing process without cumbersome verification steps. The signature data has identity recognition features, effectively preventing unauthorized use of the electromagnetic pen and enhancing the use security; fully improving the judicial effectiveness of electronic vouchers and ensuring the authenticity of the operator's identity and the credibility of data; being applicable to application scenarios requiring high security, such as the financial, government affairs, education and other industries, improving work efficiency and data authenticity.
[0024] The above embodiments only represent the implementation manners of the utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent.

Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
