Quick Definition
Continuous Authentication is an authentication technology that uses other compatibile authentication strategies (such as Plurilock's behavioral-biometric authentication) to verify users' identities on an ongoing, real-time basis, as they carry out everyday computing tasks.
Continuous Authentication is generally considered to be superior to traditional forms of (login-based) authentication because while login-based authentication checks a user's identity only once at the start of a login session, continuous authentication recognizes the correct user for the duration of ongoing work.
Continuous authentication is thus able to spot the moment at which an illicit attacker seizes control of the session, immediately ending the session, logging the account out, and protecting critical systems and data.
