Special Issue Information

Dear Colleagues,

Identity theft intimidates the growth of e-commerce and online financial and government services, and a more comprehensive approach is required to protect personal information. User identity plays a critical role in building a secure, trustworthy and privacy-enhanced identity system. The state-of-the-art approaches used to manage identities cannot endure the increasing number of cyber-attacks from expert criminals. Further research is required on the secure control of identity, enhancing interoperability, and providing end users with more direct control over their digital identity. Recent advances in machine learning and artificial intelligence offer successful solutions in designing identity systems. 

The Special Issue invites original research papers on the applications of machine learning techniques in biometrics, cyber identity, and identity management. Relevant topics include, but are not limited to:

  • Machine learning and deep learning techniques in biometrics and cyber identity;
  • Machine learning, neural netwoks and artificial intelligence methods in identity management;
  • Privacy, convenience and security of identity systems;
  • Human behavior analysis and behavior modeling;
  • Continous authentication and authorization;
  • Identity ecosystem for the Internet of Things (IoT);
  • Adversarial attacks on user authentication;
  • Adversarial learning;
  • Securing the identity claim using blockchain.

Title: Silently and Continuos Authentication in Mobile Environment
Abstract: Human activity recognition is attracting interest from researchers and developers in recent years due to its immense applications in wide area of human endeavors. The main issue in human behaviour modeling is represented by the diverse nature of human activities and the nature in which they are performed by the individual makes them challenging to recognize. In this paper we propose a method aimed to recognize human activities and detect users using features gathered from accelerometer sensors widespread in wearable and mobile devices. We exploit machine learning aimed to build models with the ability to discriminate between a set of user activities: sitting, sitting down, standing, standing up and walking. Furthermore, we demonstrate that the proposed method is able to distinguish between different users and to identify the user genre. Real-world experiment shows the effectiveness of the proposed solution.
