Agenda

Encryption

Things I did:

- Ping Apple to learn about encryption of their ApplePay.js responses

- Ping W3C staff for an example of leveraging crypto and how to specify inputs, etc.

Peter: No progress

(Ian and Peter continue their actions)

Spec updates

https://w3c.github.io/webpayments-methods-tokenization/index.html

IJ: I did an update

=> moved from https://github.com/w3c/webpayments-methods-tokenization/wiki/Tokenized-Card

IJ: I propose we close 28

stpeter: thanks
... +1 to closing 28

Issue 34

Manash: I hope to have an example response by our next meeting.

Face-to-face meeting

IJ: what do people have as a vision for the FTF meeting?
... e.g., working prototype?

Manash: For that we'd need a spec ready for FPWD
... we wanted to create a completely working prototype

IJ: Could we use a URL-based id for now?

Manash: We'd like to create an end-to-end prototype
... we'd like to get the *Pay orgs into the conversation

IJ: What are the priority issues to address, Reviews to get, details to examine between now and April?
... e..g., 5 weeks to close issues
... 1 week to get WG review
... discuss at FTF meeting

Manash: with respect to the open issues on our side (1) token crypto types
... I'll work with Keyur to clarify that.
... and (2) response data example
... would also be interesting to get a sample response from Amex team as well

Ken: Yes, we can do that.
... I get the sense that we've heard from browsers except from Apple

PROPOSED:

* Schedule tokenization discussion for 8 March WPWG call...get key people to attend

tokenization issues => https://github.com/w3c/webpayments-methods-tokenization/issues

encryption issues => https://github.com/w3c/webpayments-crypto/issues

Manash: Someone should take ownership of what we should do re: public key encryption (and align with *Pay)
... I am happy to take an action to compare our response data model with those from *Pay's to help get alignment

<scribe> ACTION: Manash to analyze response data models from ApplePay, GooglePay, SamsungPay to compare with tokenization response data model

<trackbot> Created ACTION-84 - Analyze response data models from applepay, googlepay, samsungpay to compare with tokenization response data model [on Manash Bhattacharjee - due 2018-02-20].

<scribe> ACTION: Ian to schedule 8 March discussion of the tokenization proposal and wrangle participation from various vendors

<trackbot> 'Ian' is an ambiguous username. Please try a different identifier, such as family name or username (e.g., IFSF-EFT-WG-Lead, ijacobs, ijmad).

Ken: Who will reach out to Visa to get their review?
... will Discover review it as well?

Kristina: I'm going to look internally at getting review (will check with Amanda)

Ian: I will include outreach to Visa in the planning of an 8 March call

Three pieces:

* CanMakePayment() token characteristics in the request data

* Response data model

* Encryption

* Get reviews

Summarizing actions:

- manash/keyur on canMakePayment() + response model comparisons

- peter and Ian re: encryption good practice

- Ken + Kristina for reviews

- Ian to organize 8 march call and gather participants

stpeter: Looking through the issues and thinking about tokenization while out last week...there are various kinds of tokens that people talk about
... it seems that the tokenization spec is focused on issuer tokens
... and the encryption spec talks about encrypting data to the processor
... it would be helpful for us to more clearly describe in the tokenization spec what the intention is,

and what the landscape of tokens is

scribe: it would also help us keep front of mind what assumptions we have in mind

[discussion of scope]

IJ: currently limited to network (issuer) tokens based on history of discussion

stpeter: Is there a possibility of multiple encryptions?
... we need to be crisper about the architectural expectations so we know what entities are involved in those operators

next meeting

Tuesday, 27 Feb
