A user-centred identifier enables verifiable and de-centralized digital identity, and lead users to control and to generate their own identifiers using systems they trust. This is how Self-Sovereign Identity works. This paper presents the case of universities, where several different agents need their own identifier and shows a digital identity mathematical model for the academic context. Moreover, the Alastria model for the same context is detailed for a specific case of students’ mobility.
