On October 13, 2015, new laws came into force in Australia requiring telecommunications service providers to retain and store their ‘metadata’ for 2 years so that it remains available for analysis by anti-terrorism strategists and organised crime fighters. But there are ongoing issues associated with this legislative approach, including the threats to privacy thereby, and concerns that the retention system can be circumvented entirely. This paper will outline the legal and criminological questions that need to be explored in order to help policymakers work through these issues so that an appropriate balance can be struck between forestalling crime and terrorism using all available electronic means, and not unduly curtailing the legitimate rights to privacy that citizens in modern democracies currently expect to enjoy.

元数据保留作为打击恐怖主义和有组织犯罪的一种手段：来自澳大利亚的视角

2015 年 10 月 13 日，澳大利亚新法律生效，要求电信服务提供商将其“元数据”保留和存储 2 年，以便反恐战略家和有组织的犯罪分子可以对其进行分析。但是，与这种立法方法相关的问题一直存在，包括由此对隐私造成的威胁，以及对可以完全规避保留系统的担忧。本文将概述需要探讨的法律和犯罪学问题，以帮助政策制定者解决这些问题，以便在使用所有可用电子手段预防犯罪和恐怖主义之间取得适当平衡，而不是过度限制合法权利现代民主国家的公民目前期望享有的隐私。
