The development of this tool, called the Instant Image Identifier, was preceded by extensive research, which is summarised below. 

The purpose of the preliminary study was, among other things, to map existing CSAM datasets and tools, what and how data is being collected and managed by, for example, Interpol and the Dutch police. Existing legislation, different classification systems and the technological landscape were also examined. The research showed, among other things, that there is no unambiguous definition of CSAM. And legislation on CSAM appears to differ greatly from country to country. 

Recommendations have therefore been made, such as the need for a clear-cut definition of CSAM, a standardised classification system and the linking of existing CSAM hash lists. 

Based on the preliminary research and the recommendations, the Instant Image Identifier tool (“3-is”) was further developed. The tool allows users, such as web providers, to check whether uploaded files occur in datasets of known online child sexual abuse material (CSAM). The goal is to detect and remove such materials from the internet as quickly as possible. 

A summary of the preliminary study and a summary of the recommendations are also available.
