1 Scope
The present document demonstrates the feasibility of the Smart Identity as it is defined in ETSI TR 103 875-1 [i.1].
It defines, for a specific use case (e-health), the Smart Identity (ID) and provides an associated Proof of Concept (PoC).

4 Smart Identity: from definition to PoC design
4.1 Identity definition
The notion of identity is complex and polysemous. A definition is available in [i.2].
It depends on the point of view to consider what an individual can be, and on the use that the Smart ID want to make of
this identity.
It is possible to identify 3 domains of identification which are cumulative:
1) Civil and legal identity
This identity traditionally and mainly consists of the following elements:
- surname, first name, gender, nationality, filiation (relationships), date and place of birth.
This identity is deemed to be stable throughout life.
2) Biological identity: Height, weight, eye color, retina, fingerprint, DNA
Some attributes of this identity can be used to formally identify a person, in addition to the civil identity.
3) Social and personal identity
It is made up of many sociological and psychological elements: place of residence, profession, standard of
living, hobbies, tastes, friends, beliefs, commitments, etc.
It is built, it evolves and is enriched during life, it is never fixed.
These are identities that can be described as objective or suffered (civil, legal, biological). But there are also subjective
and desired identities, corresponding to the way an individual decides for themselves how they intend to present
themselves to others. It is a kind of narrative identity. Social networks and the use of pseudonyms and avatars in
cyberspace are a tangible manifestation of this. It can be noted in this regard that in the digital world it is possible to
have several identities.
The Smart ID is created with:
• The attributes of the objective identity of the person.
• The available resources (equipment, services).
It considers the sequence of the user roles in space-time: objectives, activities, tasks, schedule.
It takes care of the information used to make awareness choices.
More simply, the Smart ID is thus the representation of a person:
• What the user is
• What the user has
• What the user is doing

• What is the user's knowledge
4.2 From Identity to User Profile

Figure 1: Relationship between Identity definition and user profile model
The "user profile" is therefore the informational representation of the user's identity (figure 1) in the digital ecosystem,
including:
• Personal information:
- Legal identity
- Identifications
- Roles (worker, patient, parent, benevolent, etc.)
• User centric characteristics that impact configurations:
Actions according to:
- Preferences
- Space-time (agenda)
- Location
• The resource description according to the location:
- Internal resources (equipment, network, services)
- External resource
