Sweetie 2.0 : Using Artificial Intelligence to Fight Webcam Child Sex Tourism

This book centres on Webcam Child Sex Tourism and the Sweetie Project initiated by the children’s rights organization Terre des Hommes in 2013 in response to the exponential increase of online child abuse. Webcam child sex tourism is a growing international problem, which not only encourages the abuse and sexual exploitation of children and provides easy access to child-abuse images, but which is also a crime involving a relatively low risk for offenders as live-streamed webcam performances leave few traces that law enforcement can use. Moreover, webcam child sex tourism often has a cross-border character, which leads to jurisdictional conflicts and makes it even harder to obtain evidence, launch investigations or prosecute suspects.

Terre des Hommes set out to actively tackle webcam child sex tourism by employing a virtual 10-year old Philippine girl named Sweetie, a so-called chatbot, to identify offenders in chatrooms. Sweetie 1.0 could be deployed only if police officers participated in chats, and thus was limited in dealing with the large number of offenders. With this in mind, a more pro-active and preventive approach was adopted to tackle the issue. Sweetie 2.0 was developed with an automated chat function to track, identify and deter individuals using the internet to sexually abuse children. Using chatbots allows the monitoring of larger parts of the internet to locate and identify (potential) offenders, and to send them messages to warn of the legal consequences should they proceed further.

But using artificial intelligence raises serious legal questions. For instance, is sexually interacting with a virtual child actually a criminal offence? How do rules of criminal procedure apply to Sweetie as investigative software? Does using Sweetie 2.0 constitute entrapment? This book, the outcome of a comparative law research initiative by Leiden University’s Center for Law and Digital Technologies (eLaw) and the Tilburg Institute for Law, Technology, and Society (TILT), addresses the application of substantive criminal law and criminal procedure to Sweetie 2.0 within various jurisdictions around the world.

This book is especially relevant for legislators and policy-makers, legal practitioners in criminal law, and all lawyers and academics interested in internet-related sexual offences and in Artificial Intelligence and law.
