Common questions
How is a digital footprint different from a digital shadow?+
A digital footprint generally refers to data traces a person deliberately creates, such as a social media post or account registration, whereas a digital shadow refers to data generated about a person by others or by passive systems, such as being mentioned in someone else's post or captured in a public record without direct action on their part.
Why does an investigator map a subject's digital footprint across multiple platforms rather than one source?+
A single platform gives an incomplete and potentially misleading picture, since accounts and activity are often fragmented across services with different privacy settings and audiences, so correlating footprints across domains, forums, and social platforms builds a more reliable composite of the subject's online presence and connections.
