State Street Corporation is looking for a solution to authenticate and validate supplier identity. This project is focused on understanding and defining digital identity to improve State Street Corporation’s supplier onboarding and vendor identification process. We start by researching digital identity and identifying key requirements for State Street Corporation. Using Python and Excel we analyze the supplier spend data to detect anomalies.  We also research processes and models used by credit card companies to flag risky transactions. We prototype an ARIMA time series model to monitor vendor transactions and flag transactions that does not match vendor spending pattern.
