TF4FA Volume 3

  • Dave Silver – sharing screen

(provenance components) Volume 3 – Audit Provenance Diagram v0 0.4 pptx: Volume 3 – Diagrams v0 0.5 vsdx:

  • we have had some further clarification of the components of provenance; we are using the features of the PASS Audit services to implement the provenance using its to implement capabilities of lifecycle events; using
  • the needs are to collect the audit, but the audit collection is based upon a community of interest policy. Each of the those might have to be collected and report back to the provenance repository or chain
  • focused on
  • conceptual model shown: leveraging audit service (provenance Model)
    • the application must be configured to record lifecycle events; goes to the audit disposition service, this is now both audit and provenance. And now provisioned for provenance. In process A all the lifecycle events are collected (coded into application) but the dispositions service based on the configuration policy determine which events need to be configured at a certain time. Then goes to delivery service which has multiple outputs; then to the recording service, etc.
  • action service; recording actions (probably internally)
  • alarm service – Mike wanted to make sure WG understands; there may be provenance events that are such a nature wherein... some occur wherein we send the provenance event and notify participants in that block chain that something has happened. it may be that some information in the chain has been determined to be invalid i.e. we want to notify participants that event should be ignored; i.e. its harmful to patient if accepted, we found that it was wrong and…maybe we have an alarm for that purpose--- doesn't hurt to keep or remove; just imagining scenarios for keeping it in. ; the ability to support alarm for the community of service
  • through the export service, is extracted from the local provenance repository then pushed to the community wide provenance repository which is some kind of legal record trail block chain; there is a provenance analysis service that the individual domain users can request provenance wide information.

Jim: where is the block chain shown in the model? Mike: staying away from 'block chain' saying / leaning more toward electronic ledger.

<<link to volume 3>> Dave Silver sending to Suzanne is there any specific data being recorded?

  • audit log … using the same machine because they are close
    • provenance log collects data that corresponds to lifecycle events that the community interest wants to store in their electronic leger (25 events defined, 18 of which are create/up--which is what FHIR is most interested in)
    • configure as on/off - when that event happened it triggers the provenance trail; or audit train (each use the same machine but report different paths); in the case of provenance, it typically, there is an interest that connects it to the e-leger, usually local kept. provenance different wherein you can have local rules 1-5;

community interests only cares about 2,3,4

Jim - how does the actor get recorded? i.e. national provider ID? name mike - this is conceptual model the provenance record has the agent involved in terms of provenance. we're staying at this level and to specifying conceptual model... just trying to get the big chunks in place the activity is associated with that agent. we could have Jim as actor (14706), trying to tie together the conceptual figures

Federated Provenance Domain (figure showed)

  • has for all the members in the domain, there is a provenance policy (agreed to by the members, implement in the individual means) which is then pushed to the digital leger as they occur. Policy grabs members what to collect and pushed down the left path
  • federated user has their own thing wherein they can request provenance data from the ledger (nothing to do with pushing information there) provenance service returns
    • this is mechanism to search in the digital leger
    • it’s possible in the exchange of information itself that the provenance goes it it...that’s a different process
  • there’s discussion of data moving around (JIM)...with questions 'who recorded this...?' it would somehow say dr. bob at facility: XYZ
  • md

Q Kathleen... 30:00 MikeD if you are interested in the information - you join the domain. as a conceptual model I don't want too many use cases to explore. what you're saying is logical. what I would like is to have the group to present two models... to make sure there is no disagreement with the alarm

  • presenting as we go;
  • Motion: That we accept the two diagrams as is (if they are changed then we will review again) (Mike / (no second?)
    • objections: none; abstain: none; approve: diagrams as accepted (11)

(Dave Silver to send diagrams as presented to Suzanne), Suzanne to link

‘’Intent is to have a complete set of core illustrations (presented in pieces) saying that the WG has reviewed and approved.’’

Privacy Obsolete

  • privacy remains a troubled area (no update)
  • May call an end to research, results may be somewhat indeterminate. There isn't a solid definition for privacy (changes from country to country)
  • In general, there is greater attention to protection of personal information unless govt is collecting
  • GDPR is having a big impact, changing environment around the world but still much stays the same
  • Facebook, are seeing new technologies to market you but not with credentials but as a member of a group wherein they don't need to know who you are. It’s a changing landscape
  • in the chaos it’s hard to say its bolete, big data and AI have a potential to make privacy obsolete.
    • forced agreement (wherein you can't get in unless you agree to all their terms

'Baltimore Meeting HL7
