Developing a strategy to characterize the odor prints of individuals should be relevant to support identification obtained using dogs in courts of justice. This article proposes an overview of the techniques used for the forensic profiling of human odor. After reviewing the origin of human odor-both genetic and physiological-the different analytical steps from sample collection to statistical data processing are presented. The first challenge is the collection of odor, whether by direct sampling with polymer patches, cotton gauze, etc., or indirect sampling with devices like Scent Transfer Unit. Then, analytical techniques are presented. Analyses are commonly performed with gas chromatography coupled with mass spectrometry. As they yield large amounts of data, advanced statistical tools are needed to provide efficient and reliable data processing, which is essential to give more probative value to information.
制定一种描述个体气味印记的策略，对于支持在司法法庭上使用犬类进行身份识别应该具有重要意义。本文概述了用于人类气味法医分析的技术。在回顾了人类气味的起源——包括遗传和生理方面——之后，介绍了从样本采集到统计数据处理的不同分析步骤。第一个挑战是气味的采集，无论是通过使用聚合物贴片、棉纱等进行直接采样，还是通过气味转移装置等设备进行间接采样。然后，介绍了分析技术。分析通常采用气相色谱-质谱联用技术。由于它们会产生大量数据，因此需要先进的统计工具来提供高效可靠的数据处理，这对于赋予信息更多证明价值至关重要。
