Risk Roundup Webcast: Behavioral Biometric Risks Based Authentication
Behavioral Biometric Risks Based Authentication
Risk-based authentication, a non-static authentication system that considers the profile of digital users requesting access to the computer system to determine the risk score in real-time, has been getting a lot of attention. Moreover, a trend is emerging of integrating biometric data with real-time authentication processes. While many different models are emerging for biometric identification, digital users’ integration of machine learning brings significant potential to human user identification and authentication process.
While there are two significant forms of biometrics: those based on physiological attributes and those based on behavioral characteristics that are being applied, each class of biometrics brings its own set of risks and rewards. As a result, it is crucial to understand and evaluate different modes and mechanisms of biometrics.
Biometric Authentication
Biometric authentication is commonly understood to be the process of verifying human identity using body measurements or other unique characteristics of the human body that would allow logging in digital service, any digital application, a connected device, and so on. Biometric identification verifies individuals based on their body measurements and mechanisms and is further divided into two major groups.
Physiological biometrics integrates the measurement of focused physiological features of a human body. It can be the face, fingerprints, human retina, blood vessel patterns, hand geometry, iris patterns, and more into an automated authentication process.Behavioral biometrics extract and integrate relevant information about human behavior and patterns such as variations in speech, keystroke, posture, and the way we do things into the human user authentication process.
It seems that the current trends are leaning towards physiological biometrics. While they are generally perceived to be extremely robust and secure, the emerging reports indicate that fingerprints can be spoofed and so on. As a result, there is a need to understand that any biometric solution that is to be used in cyberspace must be effective and yet very unobtrusive.
In comparison, while behavioral biometrics are unobtrusive – they are perceived to be frailer than physiological techniques. The reason is that the signatures can be forged, speech can be replicated, postures can be built through moderately sophisticated speech synthesis machinery, and so on.
Building Digital User Profile
Depending on the selected behavioral attribute, type, timing, and movement direction, along with mouse clicking actions and more, are commonly used to build a profile of a digital user. This user profile information is then used for authentication purposes.
It seems that most emerging system relies on a continuous user monitoring process. As a result, they require the user to interact continuously to derive enough statistical information regarding their mouse dynamics or any behavioral attribute selected. Individually and collectively, the results seem to be dependent on the number of individuals involved in the process and their characteristics. This means that, even with a large amount of data collected, the results can be vastly different if we change the group being evaluated and enrolled.
The reason is, it is challenging to obtain an accurate sample representative of the user population since it is difficult to characterize the population. This means there can only be two algorithms compared using the same test data and groups. The results also seemingly vary according to the final use. Any system used to identify an individual is less accurate than an operation used just to authenticate the user. Besides, the system that computes the risk profile and risk scores must be diligently maintained and updated as new threats emerge faster than humans can comprehend. Since many ways can lead to unauthorized access, it is important to have a structured analysis before these systems can be commercially used.
Computational Resources
It seems that while behavioral biometrics has great potential, to create an identification and authentication system that is trustable, scalable, and secure needs a lot more work. Further studies are necessary to evaluate the performance of the behavior biometric algorithm and its security. The time is now to assess behavioral biometric trends for user identification and authentication.
