Selective Disclosure Request

The Selective Disclosure Request is created by a client app and sent to a user's mobile app during the Selective Disclosure Flow.

The request can be either signed or unsigned.

Name Description Required
type MUST have the value shareReq yes
iss The DID of the signing identity yes
iat The time of issuance yes
exp Expiration time of JWT no
callback Callback URL for returning the response to a request no
net network id of Ethereum chain of identity eg. 0x4 for rinkeby no
act Ethereum account type: general users choice (default), segregated a unique smart contract based account will be created for requesting app, keypair a unique keypair based account will be created for requesting app, devicekey request a new device key for a Private Chain Account, none no account is returned no
requested DEPRECATED The self signed claims requested from a user. Array of claim types for self signed claims. Currently supported: ["name", "email", "image", "country", "phone"] no
verified DEPRECATED The verified claims requested from a user. Array of claim types for self signed claims eg: ["name", "email"], see Verified Claims no
claims Requirements for claims requested from a user. See Claims Specs and Verified Claims no
permissions An array of permissions requested. Currently only supported is notifications no
boxPub 32 byte base64 encoded Curve25519 public key of requesting identity. Use to encrypt messages sent to callback URL no
issc The self signed claims for the iss of this message. Either as an Object of claim types for self signed claims eg: {"name":"Some Corp Inc", "url":"https://somecorp.example","image":{"/":"/ipfs/QmSCnmXC91Arz2gj934Ce4DeR7d9fULWRepjzGMX6SSazB"}} or the IPFS Hash of a JSON encoded equivalent. See Issuer Claims no
vc Array of Verified Claims JWTs or IPFS hash of JSON encoded equivalent about the iss of this message. See Issuer Claims and Verified Claims no
rpc URL for the JSON RPC endpoint, ie: https://mainnet.infura.io/. Useful for Private Networks. The net_version method shoud return the same networkId as the filed net. The JSON RPC endpoint must provide the following methods: eth_getTransactionCount, eth_getBalance, eth_estimateGas, eth_gasPrice, eth_sendRawTransaction, eth_getTransactionReceipt no

The attributes redirect_url and callback_type can also be appended to the signed request as URL encoded query parameters outside of the signed payload. They are used to specify how you want the response and control returned. For more details see Messages.

Claims Spec

A Claims Spec allows you to request claims with very specific properties. This is based on the claims spec in OpenID-Connect but adapted to support Verifiable Claims.

This replaces the requested and verified parameters of this request. You may still include requested and verified to provide support for older clients. But they will be ignored if by newer clients if the claims field is present.

{
  iss: 'did:web:somesite.com',
  type: 'shareReq',
  claims: {
    verifiable: {
      email: {
        iss: [
          {
            did: 'did:web:uport.claims',
            url: 'https://uport.claims/email'
          },
          {
            did: 'did:web:sobol.io',
            url: 'https://sobol.io/verify'
          }
        ],
        reason: 'Whe need to be able to email you'
      },
      nationalIdentity: {
        essential: true,
        iss: [
          {
            did: 'did:web:idverifier.claims',
            url: 'https://idverifier.example'
          }
        ],
        reason: 'To legally be able to open your account'
      }
    },
    user_info: {
      name: { essential: true, reason: "Show your name to other users"},
      country: null
    }
  }
}

Verifiable Claims Spec

This is an json object that lives at the verifiable key within the claims object. It is not required, but provides you flexibility in clearly specifying the kind of claims you need.

Name Description Required
type The key in the verifiable object is the claims type requested yes
essential This claim is essential. A response should not be returned if user does not have this claim no
iss Array of {did, url} objects where did is DID of allowed issuer of claims and url is URL for obtaining claim, did is required but url is not no
reason Short string explaining why you need this no

Examples:

{
  email: {
    essential: true,
    iss: [
      {
        did: 'did:web:uport.claims',
        url: 'https://uport.claims/email'
      },
      {
        did: 'did:web:sobol.io',
        url: 'https://sobol.io/verify'
      }
    ],
    reason: 'Whe need to be able to email you' 
  }
}

User Info Spec

This is an json object that lives at the user_info key within the claims object. It is not required, but provides you flexibility in clearly specifying the kind of self presented user claims you need.

NOTE: These are claims specifically made by the user themselves and are not verifiable by an external party.

Name Description Required
type The key in the verifiable object is the claims type requested yes
essential This claim is essential. A response should not be returned if user does not have this claim no
reason Short string explaining why you need this no

Per the OpenId spec if the value of the claim type in the object is null then it is a non essential value.

Examples:

{
  email: {
    essential: true,
    reason: 'Whe need to be able to email you' 
  },
  name: null,
  phone: {
    reason: 'So we can notify you by text'
  }
}

Unsigned Requests (Deprecated)

To perform an unsigned selective disclosure request append the request parameters as URL encoded query parameters to one of the above endpoints and open it. Eg.:

me.uport:me?callback_url=https://mysite.com/callback&label=My%20Site

The following

Name Description Required
callback_url The URL that receives the response yes
callback_type Valid values post or redirect. Determines if callback should be sent as a HTTP POST or open the link (redirect). If unspecified, the mobile app will attempt to pick the correct one no
client_id The DID of the requesting identity no
label Plain text name of client to be displayed to user no
network_id Network ID of Ethereum chain of identity eg. 0x4 for rinkeby no
