项目摘要

The aim of the Isis project is to develop an ethics-centred monitoring framework and tools for supporting law enforcement agencies in policing online social networks for the purpose of protecting children. The project will develop natural language analysis techniques to help identify paedophiles from chat logs and monitoring mechanisms that can be non-invasively attached to file sharing systems for identifying the distributors of child abuse media. The ethical issues associated with such monitoring activities will be rigorously studied and consistently fed back into the development of the framework and tools. The project results will be used and evaluated by the Child Exploitation and Online Protection (CEOP) centre as part of their own policing activities.Recent years have seen a rapid rise in the number and use of online social networks, e.g., chat and file sharing systems. These social networks pose two significant risks in terms of child exploitation:1. Paedophiles predating on childrenChildren actively participate in chat rooms and web-based communities. Paedophiles can use such forums to predate on children (highlighted by the arrest and conviction of Lee Costi [Guardian, 23/06/06]), or even to plan paedophilia-related activities (illustrated by the conviction of paedophiles who were using such systems to plan child abuse [Guardian, 6/02/07]). These concerns are reflected by the formation of the Virtual Global Taskforce, the launch of the CEOP and Scottish legislation to criminalise the 'grooming' of children in chat rooms.2. Paedophiles distributing and sharing child abuse mediaPaedophiles can formulate their own social networks using mechanisms, such as file-sharing systems, in order to distribute and share child abuse media. A recent study at Lancaster University found that 1.6% of searches and 2.4% of responses on the Gnutella peer-to-peer network relate to illegal sexual content (including child abuse media). Given the system's scale, these results suggest that, on the Gnutella network alone, hundreds of searches for illegal images occur each second. Isis aims to address three major research challenges in this context:1. How to identify active paedophiles across online communities?Paedophiles often masquerade as children in order to establish contact with potential victims and gain their trust. Distinguishing the innocent interaction amongst children or amongst children and adults from such predatory advances is a non-trivial task. At the same time paedophiles may use multiple online identities and known paedophiles may move to other online social networks upon detection in one network. It is, therefore, vital that once a paedophile is detected in one network, s/he can be successfully detected in other networks which s/he may attempt to employ for grooming children. 2. How to identify the core distributors of child abuse media?The key research challenge is to accurately identify child abuse media from the plethora of perfectly legal material that exists within file sharing systems. Paedophiles often use specialised vocabulary to describe their shared media/a vocabulary that evolves and changes over time/and operate over different file sharing networks. Any monitoring framework must be non-invasively attachable to existing file sharing systems given the wealth of such systems and clients available today. Such monitoring tools must also be able to distinguish core distributors of such media from mere users to help law enforcement agencies in tackling the problem at its roots.3. How to ensure that such developments maintain ethical practices?The development of such monitoring and analysis techniques raises a number of ethical challenges pertaining to utilising the framework and tools in a beneficial way for child protection while protecting innocent users of online social networks and safeguarding their privacy.

Isis 项目的目标是开发一个以道德为中心的监控框架和工具，以支持执法机构对在线社交网络进行监管，以保护儿童。该项目将开发自然语言分析技术，帮助从聊天日志和监控机制中识别恋童癖者，这些监控机制可以非侵入性地连接到文件共享系统，以识别虐待儿童媒体的传播者。与此类监测活动相关的道德问题将得到严格研究，并不断反馈到框架和工具的开发中。该项目结果将由儿童剥削和在线保护 (CEOP) 中心使用和评估，作为其自身警务活动的一部分。近年来，在线社交网络（例如聊天和文件共享系统）的数量和使用量迅速增加。这些社交网络在儿童剥削方面构成了两个重大风险：1。恋童癖者对儿童进行掠夺儿童积极参与聊天室和网络社区。恋童癖者可以利用此类论坛来掠夺儿童（以 Lee Costi 的逮捕和定罪为重点 [卫报，2006 年 6 月 23 日]，甚至策划与恋童癖相关的活动（以使用此类系统策划虐待儿童的恋童癖者被定罪为例 [卫报，2007 年 6 月 2 日]）。这些担忧反映在虚拟全球工作组的成立、CEOP 的启动以及将聊天室中“诱骗”儿童定为刑事犯罪的苏格兰立法中。2。恋童癖者分发和共享虐待儿童媒体恋童癖者可以使用文件共享系统等机制构建自己的社交网络，以便分发和共享虐待儿童媒体。兰卡斯特大学最近的一项研究发现，Gnutella 点对点网络上 1.6% 的搜索和 2.4% 的回复与非法色情内容（包括虐待儿童媒体）有关。考虑到系统的规模，这些结果表明，仅在 Gnutella 网络上，每秒就会发生数百次非法图像搜索。 Isis 旨在解决这一背景下的三大研究挑战：1．如何识别在线社区中活跃的恋童癖者？恋童癖者经常伪装成儿童，以便与潜在受害者建立联系并获得他们的信任。将儿童之间或儿童与成人之间的无辜互动与此类掠夺性行为区分开来是一项艰巨的任务。与此同时，恋童癖者可能会使用多个在线身份，并且已知的恋童癖者可能会在一个网络中检测到后转移到其他在线社交网络。因此，至关重要的是，一旦在一个网络中检测到恋童癖者，他/她就可以在她/他可能试图用来诱骗儿童的其他网络中成功检测到。 2. 如何识别虐待儿童媒体的核心传播者？关键的研究挑战是从文件共享系统中存在的大量完全合法的材料中准确识别虐待儿童媒体。恋童癖者经常使用专门的词汇来描述他们的共享媒体/随着时间的推移而演变和变化的词汇/并在不同的文件共享网络上运行。考虑到当今可用的此类系统和客户端的丰富性，任何监控框架都必须能够非侵入性地连接到现有的文件共享系统。此类监控工具还必须能够区分此类媒体的核心传播者和单纯用户，以帮助执法机构从根本上解决问题。3。如何确保此类发展保持道德实践？此类监测和分析技术的发展提出了许多道德挑战，这些挑战涉及以有益的方式利用该框架和工具来保护儿童，同时保护在线社交网络的无辜用户并保护他们的隐私。
