摘要： A transport layer security (TLS) connection is established between a signature device and the host computer via an interface (e.g., a universal serial bus (USB) interface). The signature device acts as a TLS server, and the host computer acts as a TLS client. Data such as pen data, control data, or image data may be received or transmitted via a USB bulk transfer mechanism. In one aspect, the host computer sends a command via the interface to the signature device to generate a new key pair, receives a certificate signing request (CSR) from the signature device via the interface, sends the CSR to a user certificate authority, receives a public key certificate from the user certificate authority, and sends the public key certificate to the signature device via the interface.

摘要翻译： 通过接口（例如，通用串行总线（USB）接口）在签名设备和主机之间建立传输层安全（TLS）连接。 签名设备充当TLS服务器，主机充当TLS客户端。 诸如笔数据，控制数据或图像数据的数据可以通过USB大容量传输机制来接收或传输。 一方面，主计算机通过接口向签名设备发送命令以生成新的密钥对，通过接口从签名设备接收证书签名请求（CSR），将CSR发送给用户认证中心，接收 来自用户认证中心的公钥证书，并通过接口将公钥证书发送给签名设备。

摘要： Handwriting verification methods and related computer systems, and handwriting-based user authentication methods and related computer systems are disclosed. A handwriting verification method comprises obtaining a handwriting test sample containing a plurality of available parameters, extracting geometric parameters, deriving geometric features comprising an x-position value and a y-position value for each of a plurality of feature points in the test sample, performing feature matching between geometric features of the test sample and a reference sample, determining a handwriting verification result based at least in part on the feature matching, and outputting the handwriting verification result. Techniques and tools for generating and preserving electronic handwriting data also are disclosed. Raw handwriting data is converted to a streamed format that preserves the original content of the raw handwriting data. Techniques and tools for inserting electronic handwriting data into a digital image also are disclosed.
