Modern private investigation methods: OSINT, HUMINT and verification

OSINT — open-source intelligence

OSINT involves the systematic search and analysis of lawfully accessible online and offline sources. Claims found during research should be checked against several independent sources.

HUMINT — information from human sources

HUMINT rests on focused, ethical communication and careful evaluation of what people say. Responsible handling of personal data and avoiding deceptive or prohibited methods are particularly important.

Source evaluation and reporting

Facts, probable conclusions and unverified claims must be clearly separated. A good report also explains the origin, timing, limitations and verifiability of the information.
