Abstract

When carrying out criminal investigations, Law Enforcement Agencies (LEAs) apply new technology in very effective ways. However at worst, LEAs must perform many stages twice with the help of different technical tools. When investigating the identity of criminals LEAs may apply totally different technical tools than when gathering evidences for charge, because the data provided by investigating may not be valid in court. For that reason, a new monitoring system that goes beyond state of the art is needed. Three organizational layers need attentions: 1) LEA, the people that actually retrieve and store the information. 2) Prosecutors and their offices, how they get access to the information. 3) Courts, the final destination of the retrieved information. Until now, the information gathering tools for LEAs have been engineered focusing only on the best way to retrieve the information from the target. The attention paid to the legal, integrity and chain-of-custody requirements as well as social acceptance and legal oversight in connection with retrieving information has been inadequate and guidance on the matters has existed only in manuals written by legal departments.

执法机关的合法数字证据收集:合法性、完整性和监管链要求

执法机构在进行刑事调查时，以非常有效的方式应用新科技。然而，在最坏的情况下，LEAs必须在不同技术工具的帮助下将许多阶段执行两次。在调查犯罪分子身份时，司法机构可能采用与收集指控证据完全不同的技术工具，因为调查提供的数据可能在法庭上无效。出于这个原因，需要一个超越最先进水平的新监测系统。需要注意三个组织层:1)LEA，即实际检索和存储信息的人员。2)检察机关和检察机关如何获得信息3)法院，检索信息的最终目的地。到目前为止，用于lea的信息收集工具的设计只关注于从目标检索信息的最佳方法。对检索资料方面的法律、完整性和监管链要求以及社会接受和法律监督的注意是不够的，关于这些事项的指导只存在于法律部门编写的手册中。
