The User Experience of get a user to select the appropriate piece of mobile code as a user agent for a particular Relying Party on the user's identifier.
- The context is giving users control over the identifiers that they use
- The primary context is the user's mobile smartphone. A secondary context is the user on a laptop computer connected to the internet.
- The operating assumption is that the user has contacted the RP with a browser and that the identity security code is a separate native or web application that will be referred to below as the Wallet.
- For convenience of this list a wallet can include references other wallets.
- Nothing in these requirements should be construed to require that all of the wallet code is resident on a device in the user's physical possession.
- 2021-09-20 Bloomberg reported = Robinhood Markets is testing a new crypto wallet and cryptocurrency transfer feature for its app, a long-awaited move that will make it easier for customers to send and receive digital currencies like Bitcoin. With crypto wallets, consumers can use virtual currencies without having to convert them to dollars. They also provide a single place for customers to store all of their virtual currencies, protected by a private key. Robinhood shares jumped as much as 2.1% on the news. —David E. Rovella
The following are the required success criteria for both the user and the RP in establishing and maintaining an enduring relationship. Wallets supporting ephemeral relationships are possible and may be addressed in a subsequent list as needed. The high level goal is to minimize the cognitive load on the user. The success metric of this effort is (1) the percentage of users that successfully create and maintain their own usefull identifiers under their own control and (2) the number of RPs that accept SIOP identifiers.
- RPs will have the means to test if they meet the criteria for giving users control of their own identifiers.
- RPs will provide a well-known endpoint displaying their acceptance criteria for wallets. (the need for this is TBD)
- SIOP will provide a well-known endpoint API for determining their identifier functionality that contains no user personal information and minimal correlation information.
- A user of common ability will be able to install one or more wallets and create zero or more identifiers on each wallet.
- The user can add or remove wallets at any time.
- The RP can display for the user's selection on the user's browser a small number of choices that are created entirely by browser code and information from the DOM provided by the user's browser.
- Upon selection of one of those options, the user will be able to access a wallet previously provisioned with an identifier or a wallet with a list of other wallets.
- The user will have full and effective control of the selection of an identifier that meets the RP criteria.
- If such a identifier does not exist, the user will get simple and effective instructions on creating such an identifier that does meet the criteria.
- Working together the user, the device, the browser, the wallet and the RP will establish means for the user to easily restore connectivity to the RP using the user selected identifier.
David Chadwick reported on the EIC Thursday (2021-09-19) afternoon session Decentralized Identity for the Enterprise from Esatus. Attendees were able to download the Esatus Wallet, and then install a VC and use it to access a Wordpress web site. Esatus uses the Sovrin permissioned blockchain with public read access to store issuer DIDs, schemas and VC types. The demo system allows anyone to register as an issuer and does not have a proper functioning trust regime (but this can be added). There was a demo of SOWL, a web based system for creating new VC schemas and VC types and storing these on the Sovrin test blockchain. He then created a new Applications in SOWL that will use VCs for access, through defining Entitlements and Rules. We were shown how you can build a Wordpress web site using the SAML protocol for login, but instead of un/pws, VCs are sent from the user's wallet. SOWL supports OIDC, SAML, LDAP and SCIM. One negative feature is that the wallet has to be configured with the correct Sovrin blockchain to talk to, as there are many of them in the wild. If the wrong one is chosen the demo will not work. This shows a weakness of the current blockchain based system. Why not publish the VC meta data on the web instead of in a blockchain, and then wallets would not need to choose between blockchains. A member of the audience said the current system would not pass the Granny test. The performance was also dire.
- A specification meeting these criteria will be published.
- That specification may well require new means of support from the device and browser provisioned on that device.
