The Application of the Human-Biometric Sensor Interaction Method to Automated Border Control Systems

Biometrics components are used in many different systems and technologies to verify that the user is whom they say they are. In Automated Border Control systems, biometrics components used in conjunction with a traveller's documents to make sure the user is whom they say they are so that they can cross into a countries borders. The systems are expected to verify the identity with a higher degree than officers who manually check travellers. Each year the number of travellers crossing through a country borders increases and so systems are expected to handle bigger demands; through improving the user experience to ensuring accuracy and performance standards increase. While the system does bring its benefits through increased speed and higher security, there are drawbacks. One of the main issues with the systems is a lack of standardisation across implementations. Passing through an automated process at Heathrow may be different to Hong Kong. The infrastructure, information, environment and guidance given during the transaction will all greatly differ for the user. Furthermore, the individual components and subsequent processing will be evaluated using a different methodology too. This thesis reports on the contrasts between implementations, looking at solutions which utilise different biometric modalities and travel documents. Several models are devised to establish a process map which can be applied to all systems. Investigating further, a framework is described for a novel assessment method to evaluate the performance of a system. An RGB-D sensor is implemented, to track and locate the user within an interactive environment. By doing so, the user's interaction is assessed in real-time. Studies then report on the effectiveness of the solution within a replicated border control scenario. Several relationships are studied to improve the technologies used within the scenario. Successful implementation of the automated assessment method may improve the user's experience with systems, improving information and guidance, increasing the likelihood of successful interaction while maintaining a high level of security and quicker processing times

Usability assessment in a multi-biometric continuous authentication system

Multimodal biometric continuous authentication systems allow to improve security, making user identity verification a continuous process rather than a one-time occurrence. Unfortunately, the usability of these systems and their adequacy for working activities are often questioned. This paper presents a usability study for a multimodal biometric continuous authentication system capable of continuously and transparently verifying user identity through face, fingerprint and keystroke traits. We evaluate the system's usability obtained varying configuration parameters. This allows identifying the more suitable parameters configuration for different usability and security requirements. The experimental campaign relies on 60 users performing pre-defined tasks while our continuous authentication system is running. Users' opinions on system usability were collected with a post questionnaire. Our findings show that users were able to complete ordinary tasks securely and without additional effort, and that they have accepted the authentication system, which only requires minimal training.Multimodal biometric continuous authentication systems allow to improve security, making user identity verification a continuous process rather than a one-time occurrence.
