Objectives

The main objectives of the ACTIBIO project are:

  • Objective 1: To research unobtrusive biometric technologies for person authentication and monitoring in controlled sensor network infrastructures. Emphasis will be put on user’s convenience through the use of minimally obtrusive or unobtrusive sensors. In addition links will be established early in the project with the Ambient Intelligence (AmI) community in order to receive input and guidelines that will make the system as transparent to the user as possible and while exploring the possibility of ACTIBIO integration in a larger scale AmI environment. This will allow the integration of identity management and privacy enhancing tools with configurable, context-dependent and user-controlled attributes in static and dynamically changing environments.
  • Objective 2: To research and develop for the first time novel activity-related biometrics for continuous human authentication and monitoring. This involves the analysis of specific event related activities in order to extract new and unobtrusive biometric signatures. The system architecture will be studied in strict contact and interaction with social scientists, psychologists, ethicists and privacy advocates in order to incorporate their perspective in technology development.
  • Objective 3: To research and develop multimodal signal (behavioural and physiological) analysis techniques for the detection and understanding of patterns of activities entangled in important events and unusual patterns of a specific sensor infrastructure installation. This will involve research on human presence and activity recognition, indoors movement monitoring and non-verbal communication cues (body language, facial expressions, speech intonation patterns etc.).

    Event recognition is the most challenging since it involves going from raw signals to events related to user’s behaviour, physical state, mental state, context, communication with others, etc. Algorithms will be developed for the detection and recognition of specific trigger events that have discriminating potential and may be used for the robust identification of individuals. The focus will be on the unobtrusiveness of the approaches to be followed and on the early or late stage multimodal fusion of the information extracted by processing various modalities.

  • Objective 4: To develop the semantic framework for the representation of human activities to be monitored and the analytical reasoning approaches for decision making. This involves the development of a common meaning representation framework for all supported activities for semantic fusion. This will be a well-defined operation for combining partial meanings that arrive from different actions. The resulting fused semantic meaning representation will contain information about activity, state, events, features, etc.
  • Objective 5: To set up a multipurpose and multisensorial security installation that will collect, fuse, analyse and visualise data originating from various sensors integrated to various service infrastructures. This involves also the development of a flexible, scalable and context-aware, secure and resilient architecture and technologies to enable dynamic management policies that ensure end-to-end secure transmission of data across heterogeneous local infrastructures and networks, including dynamic networks of tiny insecure sensor devices (EEG/ECG physiological ENOBIO sensor, wearable sensors, a sensing seat sensor, sound-based sensor for activity recognition). This will allow the real-time detection and recovery capabilities against intrusions, malfunctions and failures.
  • Objective 6: To evaluate the proposed system using three specific installations in pilot sites: a) the fixed seat/position office scenario, b) the car scenario and c) the fixed workplace security operator accessing “always on” devices. Evaluation should include also: a) ethical evaluation, b) privacy impact assessment and c) psychological impact assessment. Pilots will be designed in strict collaboration with an ethical advisor and in case submitted to the approval of an independent committee.
