Abstract

The invention discloses an encrypted signature handwriting device and method. The encrypted signature handwriting device comprises a host processor and a handwriting display module connected with the host processor, wherein the handwriting display module is used for displaying input trace information and sending an obtained trace coordinate to the host processor; and the host processor is used for acquiring code information and signature information according to received trace coordinate, and the code information and the signature information which is encrypted by utilizing the code information as a secret key are sent to an external device. With the adoption of the encrypted signature handwriting device provided by the embodiment of the invention, the handwriting display module capable of acquiring the input trace information is used, the code information and the signature information can be acquired, so that a requirement that a user can input the code and sign is met, the office area is saved, and the operation process is simplified; and further, the code information is used for encrypting the signature information, and the safety of signal transmission is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to an encrypted signature handwriting device and method. Background technique [0002] In the handling of many financial services, the user needs to enter the password and then confirm the signature. For example, POS devices are widely used in the financial field. First, the user needs to enter the password through the password keyboard connected to the POS machine, and then sign on the printed confirmation sheet for confirmation. [0003] Since the signature information after signing on paper is not conducive to unified storage and management, more and more offices are currently replacing traditional paper signatures with electronic signatures. When the electronic signature method is used, the main equipment such as a POS machine needs to be connected with an electronic signature device in addition to an external password keyboard. In this way, the external interface of the main device ...
