Social networks have long become an integral part of our lives. We share photos, publish and comment on posts, subscribe to communities that interest us, and add new friends and acquaintances. Analysis of the information that a person transmits to society through a profile on social networks allows us to draw conclusions about his personality. And even a private profile can tell something about its owner. “Personality analysis through a social network profile. Internet Intelligence" reveals various methods, tools for searching and further using the obtained data in profiling to assess people in everyday life and business relationships, checking counterparties, searching for suspected persons. Using real examples, experts from the International Academy for the Study of Lies Vadim Chelpanov and Anton Rybakov talk about stages of diagnostic search, demonstrating the practical application of open source intelligence (OSINT) methods. The book also contains resources, links, and recommendations for further study and learning.
