摘　　要：区别于纸质笔迹,电子化笔迹会受到手写板的干扰,因而需区分其特征是人的书写动作习惯还是手写板的特定性反映。实验选取鉴定价值较高但易受书写工具和载体影响的起笔、收笔和笔痕3种笔迹特征作为研究对象,以3个参数具有代表性的手写板作为实验设备,将笔画作为观察视角,对电子化笔迹的特征开展定性和定量分析。结果表明,不同手写板上笔迹的起笔、收笔和笔痕特征均存在特殊性形态,且倾向性呈现的具体特征类型也差异显著,这共同构成手写板的特定性反映,并证明手写板会对书写动作的反映造成干扰。因此,在电子化笔迹的鉴定中,应避免将笔迹中的手写板特定性反映视为人的书写动作习惯,而应将其视为非本质差异。排除电子化笔迹中手写板特定性反映的干扰,有利于提高电子化笔迹鉴定的准确性。Different from paper-based handwriting,electronic handwriting is susceptible to interference from the handwriting tablet,making it necessary to distinguish whether its characteristics are due to human writing habits or specificity of the writing tablet.In the experiment,three kinds of handwriting characteristics including initial stroke,final stroke and stroke marks were selected as the research objects,which are of high identification value but easily influenced by writing tools and media.Three representative writing tablets with distinct parameters were used as the experimental devices and the strokes were utilized as the observation perspective to conduct qualitative and quantitative analysis of the characteristics of electronic handwriting.The results showed that the characteristics of initial strokes,final strokes,and stroke marks on different writing tablets exhibited special forms,and specific feature types presented by the tendencies significantly varied,which together constituted the specific reflection of handwriting tablet and confirmed the writing tablet would interfere with the reflection of writing actions.Therefore,in the identification of electronic handwriting,it is essential to avoid considering the specificity of the writing tablet as human writing habits,but rather to view them as non-essential difference.Eliminating the interfer-ence of specificity of the handwriting tablet in electronic handwriting is conductive to improve the accuracy of handwriting identification.
