About

ExcID is a spin-off of the Athens University of Economics and Business. ExcID pursues identity and data-centric solutions to many Internet problems, mostly focusing on security and privacy, but also more generally, while making sure that security and privacy are supported by design from the outset.

Solution & Product

Self-Sovereign Identity We enable solutions that leverage Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs), which are W3C recommendations. We develop systems for managing the lifecycle of DIDs and VCs, including issuance, presentation, and storage Access Control We provide Attribute-based and Capabilities-based access control solutions. We enable transparent protection of Web resources and IoT devices. Our solutions enable controlled, decentralized, and secure of Internet resources. Integration We enable the integration of emerging digital identity specifications (e.g., DIDs, VCs, eIDAS) with existing systems and Web applications. We develop solutions based on industry standards, including OAuth 2.0 and OpenID connect.

Innovation & Scalability

The team is leader in applying the related technologies in the fields of IoT and data sharing. The team is producing innovative products and research result that enable interoperable and secure data monetization.

Traction & achievements

ExcID co-operates with FIWARE and iSHARE foundations to provide a secure solution for sharing data generated by IoT devices located in smart homes. ExcID also co-operates with the H2020 IoT-NGIN project for applying related technologies and standards in the field of IoT. Finally the teams participates in the TRACE4EU consortium that investigates pan-european solutions for secure data and object tracking.

Team & Why Us

The team is composed of Professors George C. Polyzos and Vasilios A. Siris, and post-doc researchers Dr. Nikos Fotiou. The team has been working together for more than a decade in the Mobile Multimedia Laboratory of the Athens University of Economics and Business—AUEB. Their research was mostly focused on next generation Internet systems. The last four years the team undertook research projects related to self-sovereign identities and verifiable credentials. Inspired by the outcomes of these projects, the team set up on July 2022 the first spin-off of AUEB: ExcID. The goal of ExcID is to make technologies related to self-sovereign identity, mainstream and use them for securing our daily Internet/IoT activity. Τhe team participates in W3C’s Credentials Community Group, in OpenID connect WG, in Web Authorization Protocol IETF WG, as well as in most working groups of DIF.

Funding Needs

The team currently pursuits funds for improving its core products through R&D
