Return to User Scenario: Identity

Figure 1 represents a theoretical PII Secure Smart Contract (PIISSC). At its core, the PII Smart Contract acts as a repository of other identifiers and PII. The PIISSC by design is usable locally as just a wallet for PII and Identifiers or it can be placed onto a DIDO (i.e., Blockchain, Distributed Ledger Technology (DLT), DAG, etc). When it is being used locally, all the interactions with the PIISSC are simply transforms, when it is placed onto the DIDO or updated on the DIDO, the interactions are Transactions. Regardless local or DIDO usage, the PIISSC provides a unique hash that identifies the current state of the PIISSC.

1. A local copy of the PIISSC is downloaded onto a local computing device
2. Personal Identifiable Information and information is added to the PIISSC locally. Each update made to the PIISSC is local and considered a transform. Examples of information stored in the PIISSC are:

   1. Passport numbers
   2. Passports images
   3. Fingerprint images
   4. Credit Card and Debit card details
   5. Credit Card and Debit Card images
   6. Important Details from documents such as (Visas, work permits, marriage certificates, birth certificates, etc.)
   7. Important Document images
3. An identifier for the PIISSC in its current state is available as hexadecimal text, bar code, or QR Code. Note: every time new information is added to the PIISSC, the identifier changes.
4. Asking pre-canned questions to the PIISSC using bar codes or QR Codes (i.e., Is the person over 18? Is the person a Citizen? Does the person have a work permit?, What is the person's Credit Card Number?)
5. Asking for biometrics comparisons between the external users and the PIISSC
6. Using free form text and voice to ask questions to the PIISSC
7. The questions are analyzed according to an ontology to reformulate the questions that can be analyzed by a rules engine
