ISO/IEC TR 29198:2013提供了基于相对样本质量、相对旋转、变形和印模之间重叠来估计指纹识别评估数据集的“挑战性”或“压力”程度的指南。此外，它建立了一种构建不同难度数据集的方法。它定义了指纹识别算法技术评估中使用的指纹数据集的相对难度。难度级别基于参考样品和探针样品在上述因素中的差异。ISO/IEC TR 29198:2013解决了以下问题: 表征可归因于从同一手指采集的样本之间的差异的难度水平， 开发通过聚合影响因素来表示指纹数据集难度的统计方法， 比较不同指纹数据集的难度， 定义用于测试和报告为技术评估收集的指纹数据集的难度级别的程序， 基于比较分数分析配对数据特征， 描述用于构建用于评估的数据集的存档数据选择方法。 它提供了比较指纹数据集相对难度的指南。 在ISO/IEC TR 29198:2013范围之外的是: 定义单个指纹图像的质量， 定义用于评估或预测指纹识别算法性能的方法或明确措施。

ISO/IEC TR 29198:2013 provides guidance on estimating how "challenging" or "stressing" is an evaluation dataset for fingerprint recognition, based on relative sample quality, relative rotation, deformation, and overlap between impressions. In addition, it establishes a method for construction of datasets of different levels of difficulty. It defines the relative level of difficulty of a fingerprint dataset used in technology evaluation of fingerprint recognition algorithms. Level of difficulty is based on differences between reference and probe samples in the aforementioned factors. ISO/IEC TR 29198:2013 addresses such issues as:

• characterizing level of difficulty attributable to differences between samples acquired from the same finger,
• developing statistical methodologies for representing the level of difficulty of a fingerprint dataset by aggregating influencing factors,
• comparing the level of difficulty of different fingerprint datasets,
• defining procedures for testing and reporting the level of difficulty of fingerprint datasets collected for technology evaluation,
• analysing mated pair data characteristics based on comparison scores,
• describing the archived data selection methodology for building a dataset for evaluation.

It provides guidelines for comparing the relative level of difficulty of fingerprint datasets. Outside the scope of ISO/IEC TR 29198:2013 are:

• defining the quality of individual fingerprint images,
• defining the methodologies or explicit measures for evaluating or predicting the performance of fingerprint recognition algorithms.
