Continuous behavioral authentication
Identity verification method that continuously analyzes a user's behavioral patterns to confirm their authenticity throughout their session. This dynamic approach replaces single authentication with continuous and transparent monitoring.
Behavioral biometrics
Set of unique characteristics derived from a user's habits and ways of acting, used for identification and authentication. Unlike physical biometrics, it measures dynamic patterns such as keystroke dynamics or mouse movements.
Behavioral profile
Composite digital model that represents the unique and stable behavioral characteristics of a user. This profile is built from multiple behavioral data collected over a learning period.
Dynamic behavior analysis
Real-time process of evaluating user actions to detect deviations from established behavior. This analysis uses machine learning algorithms to identify potential anomalies.
Behavioral anomaly detection
Technique that identifies significant deviations between a user's current behavior and their established reference profile. It constitutes the main mechanism for detecting intrusion attempts in behavioral authentication.
Behavioral trust score
Continuous numerical index that evaluates the probability that the current user is indeed the legitimate person. This score is dynamically recalculated based on each user action to maintain an adaptive security level.
Keystroke pattern
Unique characteristics of how a user types on a keyboard, including speed, rhythm, and latency times between keys. These typing dynamics constitute one of the most reliable behavioral biomarkers.
Mouse analysis
Study of a user's mouse movements, clicks, and manipulation habits to create a unique behavioral signature. This analysis captures metrics such as velocity, acceleration, and movement trajectories.
Behavioral signature
Unique and persistent set of behavioral characteristics that reliably identifies a specific user. This signature gradually evolves to adapt to natural changes in user behavior.
Continuous passive verification
Authentication mode that operates in the background without requiring explicit action from the user. This transparent approach maintains security while preserving the user experience.
Behavioral learning model
Algorithmic architecture trained on behavioral data to recognize and validate authenticity patterns. These models typically use deep machine learning techniques to capture the complexity of human behavior.
Behavioral identity spoofing detection
System's ability to identify when an attacker attempts to mimic the behavior of a legitimate user. This detection relies on the analysis of micro-variations that are impossible to faithfully reproduce.
Behavioral latency time
Time intervals measured between successive user actions, used as a distinctive feature in authentication. These delays reveal cognitive and motor patterns unique to each individual.
Typing cadence
Characteristic rhythm and speed with which a user types text, including natural pauses and accelerations. This behavioral metric remains remarkably stable for the same user.
Cursor velocity
Measurement of mouse pointer movement speed, which presents unique characteristics for each user. Velocity combined with acceleration creates a distinctive movement profile.
Touch pressure
Force and rhythm exerted on touchscreens or touchpads, varying according to the user and emotional state. This metric enriches the behavioral profile with subtle physiological data.
Rythme de navigation
Pattern caractéristique de la manière dont un utilisateur explore les interfaces et navigue entre les pages. Ce rythme inclut les temps de séjour, les séquences de clics et les habitudes de défilement.
Séquence d'actions
Ordre et timing des opérations effectuées par un utilisateur lors de l'accomplissement d'une tâche. Ces séquences révèlent des habitudes cognitives et procédurales uniques.
Adaptation comportementale
Capacité du système d'authentification à ajuster progressivement le profil utilisateur en réponse aux évolutions naturelles du comportement. Cette adaptation évite les faux positifs tout en maintenant la sécurité.
Vectorisation comportementale
Processus de conversion des données comportementales brutes en vecteurs numériques multidimensionnels pour l'analyse algorithmique. Cette transformation permet l'application de techniques de machine learning avancées.
