    Abstract: 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. The geometric features may further comprise values derived from the geometric parameters, such as direction and curvature values. The handwriting verification result can be further based on a count of unlinked feature points. Handwriting-based user authentication methods can employ such handwriting verification methods, or other handwriting verification methods.

    Abstract translation: 公开了手写验证方法和相关的计算机系统以及基于手写的用户认证方法和相关的计算机系统。 手写验证方法包括获得包含多个可用参数的手写测试样本，提取几何参数，导出包括测试样本中的多个特征点中的每一个的x位置值和y位置值的几何特征，执行 测试样本的几何特征与参考样本之间的特征匹配，至少部分地基于特征匹配来确定手写验证结果，并输出手写验证结果。 几何特征还可以包括从诸如方向和曲率值的几何参数导出的值。 手写验证结果可以进一步基于未链接的特征点的计数。 基于手写的用户认证方法可以采用这种手写验证方法或其他手写验证方法。

    Abstract: A terminal device uploads data to a storage device. The terminal device includes a processor and a memory storing instructions that cause the device to determine whether data to be uploaded is a file or a partial dataset being used by an application, determine whether one or more data objects created in a given format is included in the data to be uploaded determined to be the partial dataset, generate image data and a shared byte string from the data to be uploaded if the data objects created in the given format are included in the data to be uploaded, send the data to be uploaded to the storage device as shared data if the data to be uploaded is the file, and send the image data and the shared byte string to the storage device as the shared data if the data to be uploaded is the partial dataset.
