In the picture are represented the following delegation’s vectors:
- Vector V1 represents the delegation of the action “Access” from Authorizing User (delegator) to Requester (delegated agent).
- Vector V2 represents the delegation of the action “Authorization” from the Host (delegator) to Authorization Manager (delegated agent).
- Vector V3 represents the delegation of the action “Consent” from the Authorization Manager (delegator) to Authorizing User (delegated agent).
The degree of trust of the entire process of data sharing can be calculated as length of resulting vector from summing delegation’s vectors (V1+V2+V3):
Without direct Authorizing User Consent
V1+V2 = (2,1)+(-1,1) = (1,2)
Degree = Length (V1+V2) = 2.23
With direct Authorizing User Consent
V1+V2+V3= (2,1)(-1,1)(0,-2) = (1, 0)
Degree = Length (V1+V2+V3) = 1
