Types of Behavioral Biometrics in Continuous Authentication
Keystroke Dynamics
Keystroke dynamics focus on analyzing how people type, including their speed, pressure on keys, and timing between strokes. This data helps build a profile unique to each user [1][2].
For example, financial institutions use keystroke analysis in online banking platforms to verify users during active sessions. This adds an extra layer of security that works quietly in the background while users manage their accounts [2].
| Keystroke Factor | What It Measures | Security Role |
|---|---|---|
| Typing Speed | Words per minute and consistency | Establishes a user's baseline behavior |
| Key Press Duration | How long each key is pressed | Creates a distinct typing signature |
| Inter-key Timing | Time between consecutive keystrokes | Captures rhythm and unique patterns |
In addition to typing, continuous authentication also looks at how users interact with devices through mouse and cursor movements.
Mouse and Cursor Movements
Mouse and cursor movements are another important method for continuous authentication [1][4].
For instance, Twosense AI's Behavioral MFA system applies this technology in workplace settings. By analyzing cursor behavior, it ensures seamless authentication throughout the day without requiring repeated logins, all while maintaining high security standards [5].
As mobile usage grows, analyzing touch screen behavior has also become a key component of continuous authentication.
Touch Screen Behavior
Touch screen behavior examines how users interact with their devices, including:
- Touch pressure: Variations in how hard users press the screen.
- Swipe patterns: Speed and direction of swipes.
- Gesture habits: Use of multi-finger gestures.
Developers now incorporate these behaviors into security systems. For example, the European Data Protection Supervisor (EDPS) has highlighted how touch screen analysis enhances continuous authentication by tracking user interactions during app sessions [3].
This method works because it builds detailed profiles based on natural user behavior, all while staying unobtrusive. Users can interact as they normally would, while the system quietly verifies their identity through unique touch patterns.
Behavioral Biometrics for User-Authentication Schemes
Security Benefits of Behavioral Biometrics
Behavioral biometrics offers powerful tools to bolster security, building on the methods already explored.
Continuous Monitoring for Threats
One major advantage is its ability to analyze user behavior patterns in real-time. This constant monitoring helps detect and respond to threats as they happen. It aligns with the NIST SP 800-207 Zero Trust Architecture, which highlights the need for "continual monitoring with possible reauthentication and reauthorization throughout user transactions" [1][2].
This goes beyond just tracking activity - it addresses a common vulnerability in security systems: overreliance on passwords.
Moving Beyond Passwords
Traditional passwords have long been a weak link in security. Behavioral biometrics steps in by detecting up to 95% of fraudulent login attempts, a significant improvement over the 70% detection rate of conventional methods [3]. This not only strengthens security but also simplifies the user experience by reducing the need for constant manual authentication.
Adapting to User Behavior
Another standout feature is its ability to adjust as user behaviors naturally change over time. Using machine learning, these systems continuously update user profiles to ensure authentication remains accurate. This means it can recognize shifts in typing patterns, device usage, or physical conditions without compromising security [1][3].
For behavioral biometrics to be effective, they must rely on advanced machine learning algorithms that balance adaptability, user privacy, and data protection [3].
Challenges in Using Behavioral Biometrics
Behavioral biometrics has become a promising tool for continuous authentication. However, implementing this technology comes with its own set of obstacles. Understanding these issues is key to ensuring its effective use.
Privacy and Data Security Issues
Behavioral biometric data falls under the category of sensitive information, especially under regulations like GDPR. This means organizations must implement strong security measures and obtain clear user consent to avoid privacy violations.
"The increasing use of consumers' biometric information and related technologies... raises significant consumer privacy and data security concerns and the potential for bias and discrimination." - Ralph A. Rodriguez, President, Chief Product Officer at Daon
Take the Clearview AI case as an example. It highlights how improper data collection can lead to regulatory scrutiny and emphasizes the importance of clear policies and user consent [3].
Accuracy and Error Rates
Balancing security and usability is a major challenge for behavioral biometric systems. Errors like False Acceptance (granting access to unauthorized users) and False Rejection (blocking legitimate users) can erode trust in the system. To address this, adding extra verification steps can improve accuracy without compromising security [2][4].
User Acceptance and Implementation
For any biometric system to succeed, user trust is critical. According to the FIDO Alliance's 2023 Online Authentication Barometer, biometrics is becoming a favored login method. However, concerns around privacy and control over data remain significant barriers.
Transparency and sensitivity to cultural differences can help build trust. A well-defined ethics framework that prioritizes privacy, consent, and security is especially important. This is particularly relevant in industries like banking, where preventing fraud must align with maintaining customer satisfaction [1][2].
Despite these hurdles, behavioral biometrics is already making a noticeable impact across various sectors.

Examples of Behavioral Biometrics in Use
Financial Services and Banking
Banks and financial institutions are using behavioral biometrics to enhance online security without disrupting user experiences. These systems analyze how users interact with their devices - like keystroke patterns, mouse movements, and how they handle their devices. This continuous monitoring helps verify identities during online banking sessions.
For instance, the system tracks typing rhythms and navigation habits. If anything unusual or suspicious is detected, additional authentication steps can be triggered to secure the account [1][3].
Business Security and Employee Management
Behavioral biometrics is becoming a key tool for improving workplace security and managing insider threats. By monitoring how employees interact with company devices and networks, these systems create a baseline of normal behavior for each user. Key behaviors tracked include:
- Typing speed and rhythm on work devices
- Mouse movement patterns during daily tasks
- Navigation habits within company software
If the system notices any significant deviations from these patterns, it can alert security teams or require extra verification. This approach helps prevent unauthorized access, even if login credentials are stolen [2][4].
Behavioral biometrics isn’t just limited to internal security. It’s also making waves in customer-facing industries like ecommerce.
Ecommerce and Customer Verification
Online retailers are using behavioral biometrics to fight payment fraud and protect customer accounts. By analyzing browsing habits, typing styles, and transaction timing, these systems can identify and block fraudulent activities.
To balance security and privacy, ecommerce platforms focus on specific behavioral indicators:
| Behavior Type | What It Monitors | Security Benefit |
|---|---|---|
| Navigation Pattern | How users explore products and menus | Detects bots and suspicious browsing behavior |
| Input Method | Typing speed and accuracy at checkout | Flags potential account takeovers |
| Transaction Timing | Time spent on payment pages | Highlights unusual purchasing patterns |
If unusual behaviors - like drastically different typing speeds or odd navigation paths - are detected, the system can prompt extra security steps to confirm the user’s identity before completing the transaction [2][3].
