CSAFE Handwriting Database

These data were collected to support the development of statistical approaches to the evaluation of handwriting as forensic evidence. Each enrolled participant provided handwriting samples at three data collection sessions, each at least three weeks apart. At each session participants completed a short survey and transcribed the contents of three prompts, each three times. This repository includes 27 scanned writing samples from each of 90 participants, making 2430 handwriting samples in total. In addition, survey data are available in table format including a few demographic variables and session specific information for each participant. Data were collected by researchers at the Center for Statistics and Applications in Forensic Evidence.<br>本数据集的采集旨在支撑法医证据笔迹鉴定的统计方法研发。每位入组受试者需参与三次数据采集会话，各次会话间隔至少三周。每次会话中，受试者需完成一份简短问卷，并抄写三份预设提示文本，每份文本重复抄写三次。本数据集仓库包含90名受试者各自的27份扫描书写样本，总计2430份笔迹样本。此外，还提供表格格式的问卷数据，涵盖部分人口统计学变量及每位受试者的会话专属信息。本数据集由法医统计与应用中心（Center for Statistics and Applications in Forensic Evidence）的研究人员采集完成。
