Behavioral Biometrics
Behavioral biometrics verifies identity from patterns in how a person actually interacts with a device — typing rhythm, mouse movement, touch pressure, gait from a phone's motion sensors — rather than from a discrete credential presented once and then set aside for the rest of the session. These patterns are difficult for an impostor to consciously replicate precisely, because they largely reflect habits the genuine person isn't even actively thinking about while producing them.
This is one practical way continuous authentication is actually implemented: rather than interrupting someone repeatedly with explicit re-authentication prompts throughout a session, the system observes these passive behavioral signals in the background and flags a meaningful deviation for further scrutiny, without the legitimate user needing to do anything differently at all to keep the session running normally.
