In 2021, he assessed the self-sovereign identity European framework (eIDAS) to figure out possible challenges and solutions. Previously, Cristian worked in the industry as a cryptographic engineer and infrastructure analyst. In the LeADS project, he will gain the critical thinking to lead the next wave of innovation and push his research forward.
Project Title: Big data, small data, and business practices
Objectives: In an ideal identity and access management system, the user should not have to present more credentials to a service provider than are needed to access its resources (data minimization/least privileges). The user should consent to the release of her credentials to make it compliant with GDPR. And (s)he should not be trackable though the use of his/her credentials, except in cases of abuse. The objective of this research is to define a complete framework covering both technical and legal aspects in order to guarantee the privacy of users while allowing the service providers to prevent and react to unlawful behaviours for complying with legal requirements.
