TimeTrail: Unveiling Financial Fraud Patterns through Temporal
  Correlation Analysis
Sushrut Ghimire
In the field of financial fraud detection, understanding the underlying
patterns and dynamics is important to ensure effective and reliable systems.
This research introduces a new technique, "TimeTrail," which employs advanced
temporal correlation analysis to explain complex financial fraud patterns. The
technique leverages time-related insights to provide transparent and
interpretable explanations for fraud detection decisions, enhancing
accountability and trust.
  The "TimeTrail" methodology consists of three key phases: temporal data
enrichment, dynamic correlation analysis, and interpretable pattern
visualization. Initially, raw financial transaction data is enriched with
temporal attributes. Dynamic correlations between these attributes are then
quantified using innovative statistical measures. Finally, a unified
visualization framework presents these correlations in an interpretable manner.
To validate the effectiveness of "TimeTrail," a study is conducted on a diverse
financial dataset, surrounding various fraud scenarios. Results demonstrate the
technique's capability to uncover hidden temporal correlations and patterns,
performing better than conventional methods in both accuracy and
interpretability. Moreover, a case study showcasing the application of
"TimeTrail" in real-world scenarios highlights its utility for fraud detection.
