打印文件量化检验鉴定方法的研究

Quantitative test method in forensic print document examination

本文利用层次分析法建立了打印文件特征层次结构模型,通过量化实验,得出了各层级特征的权重值;运用综合评分法确立了打印文件量化检验鉴定评测指标体系,探索了打印文件量化检验的方法和具体操作步骤,完成了打印文件检验鉴定由经验为主的定性分析到定性与定量相结合的转变,为传统的文件检验鉴定技术进行量化分析提供了新的思路和方法。

Through the application of the analytic hierarchy process, this paper establishes the hierarchical structure model of print document characteristics. Based on quantitative experiment, the weight values of each level of the print document characteristics are also determined in this paper. This paper, innovatively develops the comprehensive scoring method, based on which is established the index system of quantitative evaluation indicators in forensic print document examination. In this paper, the quantitative test method and operating procedures applied in forensic print document examination is developed. This paper contributes to the transformation of forensic print document examination test method from the qualitative analysis, which is mainly based on the examiner＇s experience, to a combination of the quantitative and qualitative analysis. This paper provides a new approach and idea for improving the quantitative analysis used in traditional forensic document examination.
