This work proposes a formalized model, grounded in forensic science, to support a unified understanding of the Trace across scientific disciplines. The model is precisely defined in mathematical terms that reflect the dynamics of an offense as expressed in Locard's Exchange principle. Specifically, this mathematical approach represents the Trace as the modification of a Scene, subsequently perceptible, resulting from the Event under investigation. Examples are provided to illustrate how this conceptualization applies to forensic science, including DNA and digital evidence. Broader implications of this model are presented in the context of COVID-19, emphasizing the value of cohesive scientific study of the Trace. The aim of this work is to stimulate more formalized study of the Trace, both from tangible and abstract perspectives, and to strengthen forensic science as a whole.
这项工作提出了一个形式化的模型，扎根于法医学，以支持在各个科学领域对痕迹进行统一理解。该模型是用数学术语精确定义的，反映了在犯罪现场中卢卡德交换原理所表达的犯罪动态。具体来说，这种数学方法将痕迹表示为场景的修改，随后可以感知到，这是由于正在调查的事件造成的。提供了示例来说明这种概念化如何适用于法医学，包括 DNA 和数字证据。在 COVID-19 的背景下提出了该模型的更广泛影响，强调了从有形和抽象角度对痕迹进行综合科学研究的价值。这项工作的目的是激发对痕迹的更形式化的研究，从有形和抽象的角度，并加强整个法医学。
