Data capture requires the provision of immutable fields that are generated deterministically in order to capture and store collected data inputs. Immutable Data capture items are identified by passive identifiers.
Table: A hash grid table describing the different states of active and passive identifiers. The states of passive identifiers are highlighted.
What is a Passive identifier?
An immutable identifier used that is generated deterministically to identify a non-governing entity, an inanimate object, or a static data item. A passive identifier can either be (1) controlled by an active identifier or (2) not controlled.
- Uncontrolled passive identifier
An immutable A passive identifier that does not require any form of ownership, control, or management.
Passive identifier types include:
Resource Self-addressing identifier
An identifier that contains a cryptographic hash of digital content. Any change to the binary state of a single byte of the digital content will invalidate the hash. A hash value is an immutable fingerprint for digital contentis deterministically generated from and embedded in the content it identifies, making it and its data mutually tamper-evident.
Linking identifier (p/p-linkage)
