Usability Evaluation Model for Biometric System considering Privacy Concern Based on MCDM Model

الملخص EN

Biometric devices play an integral role in consumer’s daily life, providing a seamless environment.

However, it is essential to measure the usability of biometrics, owing to the elements of biometrics satisfying both usability and security.

This study redefines the elements of biometrics pertaining to usability determined in previous studies and adds elements of psychological relevance, such as privacy concerns.

To organize the interrelated usability structure systemically, this paper applies the DEcision MAking Trial and Evaluation Laboratory (DEMATEL) to derive the usability structure.

Thereupon, the established structure is applied in the clustered weighted Analytical Network Processes (ANP) to generate the proposed usability evaluation model.

By these methods, the pertinent relationships between the factors are clarified and the weight of each element is determined.

In the empirical study, 106 students measured usability of the fingerprint recognition system, iris recognition system, and facial recognition system employing our usability evaluation model.

The results of this model generate the quantitative score of usability for biometric systems and suggest strategies to increase the score.

The proposed usability evaluation model can comprehensively assist usability practitioners to evaluate biometric systems.
