Footwear marks database has been the subject of numerous research projects over the past decades with a strong focus on the automation of the process of retrieving candidates for comparison. However, to date, there is still no tool able to perform a fully automate treatment of unknown crime scene marks. Making the assumption that a fully automated tool would not be available before a long time and not necessarily required, a project has emerged in Western Switzerland with the aim to commonly exploit footwear marks across several states. As this type of evidence is mainly collected in the context of volume crime, the exploitation of the footwear marks is mainly focused on the detection of links between cases in order to create forensic intelligence. Nevertheless, the search for associations between unknown marks and seized shoes is also carried out. This project resulted in a database developed in-house and now in operation. Through this tool, several forensic services are able to share their footwear marks, compare them and detect series. The links detected through this database are also shared with criminal analysis and intelligence systems. This project does not exploit any particular technological advance but have led to an operational database. This paper will highlight some of the factors that have led to the development and implementation of a successful footwear marks database connecting several police services.
鞋印数据库在过去几十年中一直是众多研究项目的主题，这些研究项目主要集中在检索候选鞋印进行比对的过程自动化上。然而，迄今为止，仍然没有任何工具能够完全自动化地处理未知犯罪现场的鞋印。基于在很长一段时间内都不会有完全自动化的工具且不一定需要该工具的假设，瑞士西部出现了一个旨在在多个州共同利用鞋印的项目。由于此类证据主要在大量犯罪的情况下收集，因此鞋印的利用主要集中在检测案件之间的联系，以建立法医学情报。然而，也会进行未知鞋印与缴获鞋子之间的关联搜索。该项目开发了一个内部数据库并已投入使用。通过该工具，几个法证服务部门能够共享他们的鞋印，进行比对并发现系列。通过该数据库发现的联系也会与犯罪分析和情报系统共享。该项目没有利用任何特定的技术进步，但已经建立了一个可操作的数据库。本文将重点介绍一些促成成功连接多个警察部门的鞋印数据库的开发和实施的因素。
