13.3.2 Authenticity Step (AS)
An AS is performed by an Actor, which can act either in an automatic (hardware,
software) or in a manual (person, organization) way (Fig.
13.2
):
There can be several types of ASs. Following OAIS, we distinguish ASs based
on the kind of Preservation Description Information required to carry out the AS.
Consequently, we have five types of steps (Fig.

):
•
