OSINT
Definition
Open-Source Intelligence. Investigation using publicly available sources: social media, satellite imagery, news archives, public databases. In deepfake casework, OSINT corroborates or contradicts the claim that a depicted event occurred, complementing signal-analysis detection.
- Definition
- Information collection from publicly available sources without authentication
- Common sources
- Social media, search engines, archives, business records, satellite imagery, news databases
- Key strength
- Legal transparency and speed, no special access required
Common questions
What sources count as OSINT?+
OSINT uses only publicly available sources without needing to log in. This includes public social media profiles, search engines, archives, registered business records, satellite imagery, news databases, and public registries. Leaked data that is already publicly available also qualifies.
How does OSINT help in forensic investigations?+
OSINT gathers context and corroborating evidence. In deepfake cases, for example, it can verify whether the depicted event actually occurred or contradict false claims. It works alongside technical signal analysis to build a fuller picture of what happened.
What makes OSINT different from other investigation methods?+
OSINT relies only on sources you can access without special permissions or authentication. You are not hacking, infiltrating, or accessing private accounts. This makes it fast, practical, and legally transparent for casework and legal proceedings.
