1.1 Analyse the relationship between data mining and data analysis in
financial crime investigation
Data mining and data analysis are closely interconnected techniques used in the
investigation of financial crimes. Data mining involves the automated process of
identifying hidden patterns, correlations, and anomalies within large datasets
using algorithms, machine learning, and artificial intelligence. It focuses on
extracting potentially useful and previously unknown information from vast
quantities of structured and unstructured data. On the other hand, data analysis
interprets and evaluates this information to draw meaningful conclusions that can
support investigative decisions. In financial crime investigations, data mining
identifies unusual financial transactions, such as repeated large deposits or
transfers to high-risk jurisdictions, while data analysis evaluates the significance
of these transactions in relation to known fraudulent behaviours. The relationship
between the two is cyclical and dynamic—data mining uncovers the data points of
interest, and data analysis refines and contextualises them to build evidentiary
value and investigative direction (Gottschalk, 2010).
1.2 Assess how these two processes complement each other in detecting
financial crimes
Data mining and data analysis are complementary in the sense that one feeds
into the other to enhance the efficiency and accuracy of financial crime detection.
Data mining acts as a filter that uncovers suspicious patterns in massive financial
datasets, such as round-dollar transactions, frequent cash deposits, or
transactions just below reporting thresholds. These findings are not immediately
actionable without the context provided by data analysis. Through analysis,
investigators can determine whether the flagged activity is criminal or benign,
correlating it with individual profiles, timelines, or known fraud schemes. For
example, while data mining might flag structured deposits (also known as
"smurfing"), it is through data analysis that investigators can link this behaviour to
money laundering or tax evasion. Together, these processes enable forensic
investigators to proactively detect and prevent financial crimes, reduce false
