Analysis of Transaction Data on Graph Structure

The Communications Security Establishment (CSE) is Canada’s national cryptologic agency. CSE is mandated to acquire and provide foreign signals intelligence and to provide advice, guidance and services to help ensure the protection of Government of Canada electronic information and information infrastructures. It also provides technical and operational assistance to federal law enforcement and security agencies. The intern’s research centred on developing a model, or clustering technique, that will enable CSE to predict communications activity. Using toy data sets, the intern graphed correspondence data with a goal of enabling the identification of clusters of activity during a set period of time, indicative of repeated communication. This will enable CSE to infer communication activity based on probabilistic modelling.
