Title: Designing Interaction Systems Using Combinatorial Optimizations

Abstract:  Combinatorial optimization is a mathematical method that is used to find an optimal possible solution to a problem with a large number of potential solutions. In the context of human-computer interactions, this method can be used to design user interfaces that are efficient, intuitive, and easy to use. It has already been applied to the design of various user interfaces, including keyboards, menu systems, graphical user interfaces, information visualizations, input methods, and haptic communication systems. The presentation will describe the principles of combinatorial optimization and discuss how they can be used to design interactive systems and interfaces. It will also provide examples of successful applications of this method in interaction design. Overall, the presentation will demonstrate the potential of combinatorial optimization in the design of human-computer interactions and interfaces.

Title: Blockchain as an Enabling Technology of Self-Sovereign Identities and Verifiable Credentials

Keywords: blockchain, digital identity, verifiable credentials, self-sovereign identity

Blockchain enables technological transformation by enhancing aspects of digitization. As a new technology, blockchain finds application in many fields of study, including digital identities and verifiable credentials.

Digital identities are fundamental and useful to people, applications and society. They take place as the fundamental innovations of recent years and are currently one of the most important research-scientific topics. Digital identities and verifiable credentials are taking their place in identifying people, digital documents – diplomas and other records – replacing paper-based documents. For example, students can authenticate their degrees by sharing and validating digital credentials, and applications can authenticate information sharing based on the self-sovereign identity (SSI) approach. The SSI approach facilitates individuals to own and control their digital identity, allowing them to decide on the sharing of their credentials and avoid third-party interference. Its foundation is based on “distributed” digital identity, that is, using digital wallets to enable individuals to generate, manage and share verifiable credentials.

In this presentation, we present a comprehensive survey of digital identities and explore the current state of digital identities (verifiable credentials) at the EU level.
