Connect is a new social network analysis software data mining computer system developed by HMRC (UK) that cross-references business's and people's tax records with other databases to establish fraudulent or undisclosed (misdirected) activity.
[2][3] From September 2016, Connect has interfaced with financial information from British Overseas Territories; these have been known tax havens.
Connect cross-references information from many other UK government databases, including: HMRC also independently looks at Google Earth.
The system deploys the chi-squared test and Benford's law to look for anomalous tax receipts.
It looks for correlation of income with lifestyle, by comparing with multivariate statistical models; outliers from expected variance will be investigated.
