<p class="MsoNormal"> David Chadwick spoke to the efficiencies gained by having the "id"<o:p></o:p></p>
<p class="MsoNormal"> He thinks it should be optional<o:p></o:p></p>
<p class="MsoNormal"> But several implementations don't use it<o:p></o:p></p>
<p class="MsoNormal"> Mike said that searching small data structures is not a big deal<o:p></o:p></p>
<p class="MsoNormal"> This is related to <a href="https://github.com/decentralized-identity/presentation-exchange/issues/231">
https://github.com/decentralized-identity/presentation-exchange/issues/231</a><o:p></o:p></p>

<p class="MsoNormal"> Brian said that processors can add identifiers to sections when processing<o:p></o:p></p>
<p class="MsoNormal"> There could be identifiers for users involved<o:p></o:p></p>
<p class="MsoNormal"> #1256: Reconcile the mapping/processing between input descriptors and submitted inputs<o:p></o:p></p>

<p class="MsoNormal"> #37: Cross Device SIOP<o:p></o:p></p>
<p class="MsoNormal"> Kristina asked if people had ideas to make a cross-device flow more secure<o:p></o:p></p>
<p class="MsoNormal"> Mike asked whether this should be in a different spec, given its phishable nature<o:p></o:p></p>
<p class="MsoNormal"> Bjorn said that MODRNA has multi-device flows using CIBA<o:p></o:p></p>
<p class="MsoNormal"> The question is how to bind the consumer device and the authenticator device<o:p></o:p></p>
<p class="MsoNormal"> In the MODRNA case, the mobile phone will be the authenticator device<o:p></o:p></p>
<p class="MsoNormal"> Bjorn said that nothing has been put into the spec to achieve the binding<o:p></o:p></p>
<p class="MsoNormal"> Mike said that CIBA is OK for payment because the payment terminal is inside the security boundary<o:p></o:p></p>
<p class="MsoNormal"> The same does not apply to random QR codes<o:p></o:p></p>
<p class="MsoNormal"> Stephanie and Brian said that payment terminals are not always secured<o:p></o:p></p>
<p class="MsoNormal"> Brian talked about how one shouldn't use phones in proximity to gas pumps<o:p></o:p></p>
<p class="MsoNormal"> There are also problems where phones are prohibited and/or when there is no service<o:p></o:p></p>
<p class="MsoNormal"> Brian said that fallbacks need to be in place when the phone can't be used<o:p></o:p></p>
<p class="MsoNormal"> Brian said that security depends upon participants vetting your identity<o:p></o:p></p>
<p class="MsoNormal"> The end terminal can't necessarily be trusted<o:p></o:p></p>
<p class="MsoNormal"> Kristina will open an issue about security considerations for cross-device flows<o:p></o:p></p>
