Active Authentication in Mobile Devices: Role of Information Fusion

Motivation and Rationale. Why is this topic important to the FG community? What makes it timely?

Nowadays everyone carries sensitive information, such as bank account details, emails or passwords in their smartphones and tablets. In addition, there is an increasing need for secure mobile applications. Traditional login authentication in such mobile scenarios, e.g., with passwords, is not safe enough, which has led to important developments in biometric authentication for mobiles, e.g., based on fingerprints and face images. These authentication mechanisms are also limited in nature, as the users are typically authenticated only once at the beginning of the session. This situation has led to a growing body of literature looking now for new ways of authentication based on continuous biometrics (also known as active authentication), which periodically authenticate the user and thus ensure security in the device beyond the entry point, and for which both face and gesture information may be very useful.

The huge scale and practical implications of secure and convenient mobile authentication make this area very important and timely to the information fusion community. In fact, this community has much to contribute to the area of biometric active authentication to overcome the challenges that are limiting now its practical application.

 An Introduction to Track-to-Track Fusion and the Distributed Kalman Filter

The increasing trend towards  connected  sensors (”internet of things” and ”ubiquitous computing”) derive  a demand  for powerful distributed estimation methodologies. In tracking applications, the ”Distributed Kalman Filter” (DKF) provides an optimal solution under certain conditions.  The optimal solution in terms of the estimation  accuracy is also achieved by a centralized fusion algorithm which receives either all associated measurements or so-called tracklets. However,  this scheme needs the result of each update step for the optimal solution  whereas the DKF works at arbitrary  communication  rates since the calculation is completely  distributed.  Two more recent methodologies  are based  on the ”accumulated  state densities” (ASD) which augment the states from multiple time instants. In practical applications, tracklet fusion based on the equivalent measurement often achieves reliable results even if full communication is not available. The limitations  and robustness of the tracklet fusion will be discussed.

At first, the tutorial will explain the origin of the challenges in distributed tracking. Then, possible solutions to them are derived and illuminated.  In particular, algorithms will be provided for each presented solution.

The list of topics includes: Short introduction to target tracking, Tracklet Fusion, Exact Fusion with cross-covariances, Naive Fusion, Federated Fusion, Decentralized Fusion (Consensus Kalman  Filter), Distributed Kalman Filter (DKF), Debiasing for the DKF, Distributed ASD Fusion, Augmented State Tracklet Fusion.

Analytic Combinatorics for Multi-Object Tracking and Higher Level Fusion

This tutorial is designed to facilitate understanding of the classical theory of Analytic Combinatorics (AC) and how to apply it to problems in multi-object tracking and higher level data fusion.  AC is an economical technique for encoding combinatorial problems—without information loss—into the derivatives of a generating function (GF).  Exact Bayesian filters derived from the GF avoid the heavy accounting burden required by traditional enumeration methods.  Although AC is an established mathematical field, it is not widely known in either the academic engineering community or the practicing data fusion/tracking community.  This tutorial lays the groundwork for understanding the methods of AC, starting with the GF for the classical Bayes-Markov filter.  From this cornerstone, we derive many established filters (e.g., PDA, JPDA, JIPDA, PHD, CPHD, MultiBernoulli, MHT) with simplicity, economy, and insight. We also show how to use the saddle point method (method of stationary phase) to find low complexity approximations of probability distributions and summary statistics.

Data Fusion for the Internet of Things

The advent of the Internet of Things (IoT) was possible due to advances on microelectronics techniques that fostered the development of smart objects able to collect, process and transmit data. The integration of these smart objects into the Internet originated the concept of Internet of Things (IoT). The IoT vision advocates a world of interconnected objects, capable of being identified, addressed, controlled, and accessed via the Internet. Such objects can communicate with each other, with other virtual resources available on the web, with information systems and human users. IoT applications often deal with a real-time monitoring of a wide range of parameters, ranging from vital signs to the heat on batteries, that can be exploited by a single or several applications whose scope and purpose are unlimited.

Although much emphasis is given in the interconnected things, the main point of the IoT paradigm is data instead of the object themselves. The   main   value  of   the   IoT   paradigm   is   the knowledge produced through the analysis of the data captured by the things. The produced knowledge can drive new business and operations. In this sense in order to explore the potential in IoT there should be mechanisms to process and analyze the enormous amount of data generated by the things producing and extracting valuable knowledge from them.

New challenges emerge in this scenario as well as several opportunities to be exploited. The devices area limited in terms of resources both memory and processing. In this context, data fusion techniques can be used to promote knowledge discovery from the huge amount of sensing data at a low power and processing cost. Data Fusion techniques deal with the association, correlation, and combination of data and information from single and multiple sources to achieve refined position and identity estimates, and complete and timely assessments of situations and threats,  and  their  significance (to  end  users  or  a target  application/system).  Employment  of  such Data Fusion techniques are useful to reveal trends in the  sampled  data,  uncover  new  patterns  of monitored variables, make predictions, thus improving decision making process, reducing decisions response times, and enabling more intelligent and immediate situation awareness.

The objective of this tutorial is to present the for Internet of Things where and how to use them in a smart environment.

The central elements of this tutorial are:

  • Internet of Things: Basic concepts, limitations and benefits
  • Where  and  how  IoT  can  benefit from  Data
  • Fusion Techniques
  • Data correlation among heterogeneous sources
  • Data fusion for resource constrained devices;
  • Implementing data  fusion  techniques  on sensors
  • Future directions

The participants will have access to the Presentation slides and Source code produced.

Extended Object Tracking:  Theory and Applications

Autonomous  systems are  an active  area of re- search  and technological  development.  These systems  require intelligence  and decision making,  including  intelligent  sensing, data collection and processing, collision  avoidance  and control. Autonomous   systems, especially  autonomous  cars need to be able to detect, recognise,  classify and track objects of interest, including  their location  and size.  In  the light of autonomous systems this tutorial will focus on tracking of extended objects, i.e., object tracking  using modern  high resolution  sensors  that give multiple  detections per object. State of the art theory will be introduced, and relevant real world applications will be shown where different  object types, e.g., pedestrians, bicyclists, and cars, are  tracked using  different sensors  such  as  lidar, radar, and camera.

Presenters: Karl Granström  and Marcus Baum


Groups and Crowds: Dynamics Modelling, Tracking and Analysis. State-of-the-Art Approaches and Beyond

Smart cities as dynamic systems of systems face a number of challenges both at the planning  stage and at the stage of real-time monitoring  and control. These require advanced tools for traffic flows prediction with different levels of granularity, multi-sensor data fusion and autonomy.  This tutorial introduces key models and methods for groups and crowds modelling, tracking and behaviour prediction.  Groups are structured objects characterised with particular motion patterns. The group can be comprised of a small number of interacting objects (e.g. pedestrians, sport players, convoys of cars) or of hundreds or thousands of components such as crowds of people.

Presenters: Lyudmila Mihaylova and Karl Granström 


Implementations of Labeled Random Finite Set Multi-Target Filters

The random finite set framework for multi-sensor multi-target tracking has attached considerable interest in recent years. It provides a unified perspective of multi-target tracking in a very intuitive manner by drawing direct parallels with the simpler problem of single-target tracking. This framework has led to the development of well-known multi-target filters such as the Probability Hypothesis Density (PHD), Cardinalized PHD (CPHD), Multi-Bernoulli filters and a recent advance, the Generalized Labeled Multi- Bernoulli (GLMB) filter, which can handle in the order of one million targets in the presence of high clutter and misdetections.

The tutorial will present the Generalized Labeled Multi-Bernoulli (GLMB) filter and demonstrate the landmark example with one million targets. Further, we will show how the GLMB filter and an approximation called LMB filters are implemented in Matlab. Matlab code for these filters will be provided to all participants. It is envisaged that participants will come away with sufficient know-how to implement and apply these algorithms in their work.

Participants should have working knowledge of random variable, probability density function, Gaussian distribution, and concepts such as state space models.

Information Quality in Information Fusion and Decision Making

Designing fusion systems for decision support in complex dynamic situations requires fusion of a large amount of multimedia and multispectral information to produce estimates about objects and gain knowledge of the entire domain of interest. Data and information to be processed and made sense of includes but is not limited to data obtained from physical sensors (infrared imagers, radars, chemical, etc.), human intelligence reports, and information obtained from open sources (traditional such as newspapers, radio, TV as well as social media such as Twitter, Facebook, and Instagram).

The problem of building such fusion-based systems is complicated by the fact that data and information obtained from observations and reports as well as information produced by both human and automatic processes are of variable quality and may be unreliable, of low fidelity, insufficient resolution, contradictory, and/or redundant. It can come from a broken sensor or a sensor improperly used in the environmental context. A message obtained from a human sensor can contain a human error or is intentionally sent to skew the information. Furthermore, there is often no guarantee that evidence obtained from the sources is based on direct, independent observations. Sources may provide unverified reports obtained from other sources (e.g., replicating information in social networks), resulting in correlations and bias. In the more malicious setting, some sources may coordinate to provide similar information in order to reinforce their opinion in the system. The fusion methods used can be insufficient to achieve the required rigor.

The success of decision making in a complex fusion driven human-machine system depends on how well knowledge produced by fusion processes represents reality, which in turn depends on how adequate data are, how good and adequate is the fusion model used, and how accurate, appropriate or applicable prior and contextual knowledge is.

The tutorial will discuss major challenges and some possible approaches addressing the problem of representing and incorporating information quality into fusion processes. In particular it will present an ontology of quality of information and identify potential methods of representing and assessing the values of quality attributes and their combination.  It will also examine the relation between information quality and context, and suggest possible approaches to quality control compensating for insufficient information and model quality.

Multisensor-Multitarget Tracker/Fusion Engine Development and Performance Evaluation for Realistic Scenarios

While numerous tracking and fusion algorithms are available in the literature, their implementation and application on real-world problems are still challenging. Since new algorithms continue to emerge, rapidly prototyping them, developing for production and evaluating them on real-world (or realistic) problems efficiently are also essential. In addition to reviewing state-of-the-art tracking algorithms, this tutorial will focus on a number of realistic multisensor-multitarget tracking problems, simulation of large-scale tracking scenarios, rapid prototyping, development of high performance real-time tracking/fusion software, and performance evaluation on realistic scenarios. A unified tracker framework that can handle a number of state-of-the-art algorithms like the Multiple Hypothesis Tracking (MHT) algorithm, Multiframe Assignment (MFA) tracker and the Joint (Integrated) Probabilistic Data Association (J(I)PDA) tracker is presented. Modules for preprocessing (e.g., coordinate transformations, clutter estimation, thresholding, registration), data association (e.g., 2-D assignment, multiframe assignment, k-best assignment), filtering (e.g., Kalman filter, Interacting Multiple Model (IMM) Estimator, Unscented Kalman filter) and postprocessing (e.g., prediction, classification) are discussed. Fusion software with different architectures is also presented. Integration of sensors like radar, ESA, angle-only, PCL and AIS/ADS-B is demonstrated. Side-by-side performance evaluation of multiple algorithms using more than 30 metrics on realistic large-scale tracking scenarios is presented. A hands-on approach with ISR360, which is an end-to-end real-time software suite for Intelligence, Surveillance and Reconnaissance, will be the cornerstone of this tutorial.

The topics will include Review of Bayesian state estimation, Multitarget tracking system architecture, Implementation of J(I)PDA/MHT/MFA trackers, Implementation of a multisensor fusion engine, Implementation of realistic simulators, Implementation of a track analytics engine, Performance evaluation of trackers (MOP/MOE), and Real-world examples.

Participants should have a basic knowledge of tracking and fusion concepts.

Multitarget multisensor tracking: from traditional to modern distributed approach

The tutorial aims to present an historical overview of multisensor multitarget tracking from the traditional “divide & conquer” approach to a more modern approach based on the theory of finite random sets/Poisson point processes, but also aims to present the most recent research achievements of the group related to distributed tracking over peer-to-peer sensor networks. The talk will initially describe the intertwined R&D activities, along several decades, between academia and industry in conceiving and implementing - on live surveillance systems - tracking algorithms for targets in civilian as well as defense and security applications. In this respect, we trace back from the alpha-beta adaptive filter to modern random set filters passing through the Kalman  algorithm  (in  its  many  embodiments),  Multiple  Model  filters,  Multiple  Hypothesis Tracking, Joint Probabilistic Data Association, Particle filters. Then,  the  presentation  will  focus  on  recent  research  achievements  on  distributed  multitarget tracking over a peer-to-peer network consisting of the radio interconnection of multiple, possibly low-cost, devices with sensing, communication and processing capabilities. In this respect, fundamental issues like distributed fusion, handling of different fields of view, distributed sensor registration, etc., and relative solutions will be thoroughly investigated. Through the talk, applications to land, naval and airborne sensors will be mentioned. Further, active as well as passive radar experiences are overviewed.

The description will have a balanced look to both theoretical and practical implementation issues including mitigation of real life system limitations.

Noise Covariance Matrices in State Space Models: Overview, Algorithms, and Comparison of Estimation Methods

Knowledge of a system model is a key prerequisite for many state estimation, signal processing, fault detection, and optimal control problems. The model is often designed to be consistent with random behaviour of the system quantities and properties of the measurements. While the deterministic part of the model often arises from mathematical modelling based on physical, chemical, or biological laws governing the behaviour of the system, the statistics of the stochastic part are often difficult to find by the modelling and have to be identified using the measured data. Incorrect description of the noise statistics may result in a significant worsening of estimation, signal processing, detection, or control quality or even in a failure of the underlying algorithms.

The tutorial introduces a more than six decades long history as well as recent advances and the state-of-the-art of the methods for estimation of the properties (or statistical description) of the stochastic part of the model with a special emphasis on the state-space model noise covariance matrices estimation. The tutorial covers all major groups of the noise statistics estimation methods, including the correlation methods, maximum likelihood methods, covariance matching methods, and the Bayesian methods. The methods are introduced in the unified framework highlighting their basic ideas, key properties, and assumptions. Algorithms of individual methods will be described and analysed to provide a basic understanding of their nature and similarities. Performance of the methods will also be compared using a numerical illustration.

The attendees will be provided with course notes and sample implementations of the selected methods.

Presenters: Ondrej Straka, Jindrich Dunik and Jindrich Havlik


Object tracking, Sensor Fusion and Situational Awareness for Assisted- and Self-Driving Vehicles: Problems, Solutions and Directions

The automotive industry has been undergoing a major revolution in the last few years. Rapid advances have been made in assisted- and self-driving vehicles. As a result, vehicles have become more efficient and more automated. A number of automotive as well as technology companies are in the process of developing smart cars that can drive themselves. While totally self-driving cars are still in their infancy, some features like self-parking, proximity detection and lane identification have already made it into production in high-end vehicles. In spite of these recent developments, significantly more research is needed in order to perfect these nascent technologies and to make them ready for mass production. This provides the motivation for this tutorial.

In this tutorial, we aim to discuss a number of problems related to assisted- and self-driving vehicles, potential solutions and directions for research & development. The issues discussed in this tutorial will span multitarget tracking, multisensor fusion and situational awareness within the context of smart cars. We will also present some of the algorithms that are available in the open literature as well as those we have developed recently. In addition, we will also discuss related computational issues and sensor technologies. Finally, we will present some results on real data.

Overview of High-Level Information Fusion Theory, Models, and Representations

Over the past decade, the ISIF community has put together special sessions, panel discussions, and concept papers to capture the methodologies, directions, needs, and grand challenges of high-level information fusion (HLIF) in practical system designs. This tutorial brings together the contemporary  concepts,  models,  and  definitions  to  give  the  attendee  a summary of the state-of-the-art in HLIF. Analogies from low-level information fusion (LLIF) of object tracking and identification are extended to the HLIF concepts of situation/impact assessment and process/user refinement. HLIF theories (operational, functional, formal, cognitive) are mapped to representations (semantics, ontologies, axiomatics, and agents) with contemporary issues of modelling, testbeds, evaluation, and human-machine interfaces. Discussions with examples of search and rescue, cyber analysis, and battlefield awareness are presented. The attendee will gain an appreciation of HLIF through the topic organization from the perspectives of numerous authors, practitioners, and developers of information fusion systems. The tutorial is organized as per the recent text:

Statistical Methods for Information Fusion System Design and Performance Evaluation

Information fusion system find their application in multiple domains from defense applications to self-driving cars, and autonomous systems. Irrespective of the application domain, the design of an information fusion system requires evaluation of a multitude of design variables which have a direct impact on the fusion system performance. These variables include various sensor types and attributes, multiple tracking and fusion algorithms (i.e., low-level information fusion (LLIF) considerations), and different situation assessment and resource management approaches (i.e., high-level information fusion (HLIF) considerations).  It is imperative for the fusion system designers to identify the significant design decisions in this large design space and subsequently quantify their impact on the end fusion performance. Traditionally, information fusion community has taken a partitioned approach of isolated design and evaluation of the various attributes of the fusion system, which assumes a lack of interactions between design decisions. However, in complex systems, such as the information fusion system, interactions between system design variables, continue to dominate the performance. 

In this tutorial, a domain-agnostic framework, based on Design of Experiments, is presented which provides holistic performance evaluation of an information fusion system. This framework leverages systems engineering principles for identifying design variables which are then investigated by statistical methods (e.g., analysis of variance) for establishing statistical significance and quantifying their impact on fusion system performance. This tutorial will discuss theoretical foundations for performing design and analysis of experiments, followed by a hands-on information fusion system application example which can be transferred to domain-specific implementation in the participant’s area of interest. A refresher on Monte-Carlo simulations and hypothesis testing will also be provided. At the conclusion of the tutorial, the participants will be able to formulate an experimental design for the fusion system performance evaluation, employ hypothesis testing for comparing uncertain data, perform analysis of variance (ANOVA) to establish statistical significance of design variables and interactions, and perform multiple comparison range tests to quantify the impact of design variables and obtain sensitivity analysis of interactions for fusion system performance evaluation.
