An Analysis Framework for Product Prices and Supplies in Darknet Marketplaces

Darknet marketplaces are an interesting research area. Most marketplaces are hosted in the Tor network as an anonymous onion service. In this paper we provide a generic approach to build a framework for the collection and analysis of product prices and supplies in such marketplaces. We focus on the technical details how to implement such a framework and how to collect, organize, and analyze the product data. For our framework implementation we provide an evaluation based on collected data from three large marketplaces and present an approach to enrich the analyzed data with additional information from external sources.
