Face Capture (Android)

Integration with AwareID

Estimated reading: 19 minutes 297 views

AwareID's Saas allows for the registration of a user using the face data collected in the previous section, Face Capture.

There are three operations when communicating with AwareID's backend:

Enrollment

Re-enrollment

Authentication

Enrollment Process Initiated from Client

This section provides details regarding Enrollment Process Initiated from Client.

Base URL

www.awareid.aware-apis.com

To perform a successful enroll using the Face SDK and AwareID there are two possible work flows. The first workflow is the most flexible and involves initiating the enrollment from the client. The second workflow option involves the use of a secondary application to initiate the enrollment and generate a QR code encoded with the session token necessary to proceed with the enrollment. The QR code is scanned from the client application and then proceeds with enrollment using the data encoded in the QR code.

To enroll by initiating from the client we have to follow 5 steps. These steps include:

  1. Retrieve an access token. This token allows communication between the client application and the AwareID servers.
  2. Get Public Key - Public Key for face data encryption
  3. Initiate an enrollment.
  4. Add device
  5. Enroll face

Enrollment Initiated from Client Step 1 - Get Access Token

Our first step is to retrieve an “access_token”. This token will be used in our next api call to retrieve an enrollment token to proceed with enrollment.

Get Access Token

   POST /auth/realms/{{customer_name}}-consumers/protocol/openid-connect/token
   Content-Type: 'application/x-www-form-urlencoded',

   "client_id": client_id
   "client_secret": client_secret
   "scope": openid
   "grant_type" : client_credentials

           "addFace"
       ]
   }

Enrollment Initiated from Client Step 4 - Add Device

The device ID is checked when performing an authentication to confirm the device enrolled is the same as the device attempting.

Device Id

   This can be retrieved in Android by using the following code
   Settings.Secure.getString(getContentResolver(), Settings.Secure.ANDROID_ID);

Add Device

   POST /onboarding/enrollment/adddevice

  }

Enrollment Process Initiated Through QR Code

To enroll by inititating through a QR code scan we first have to take in the enrollment details like first name, last name, email address and phone number and make a call to generate the QR code from a secondary application. In our demo we use a web app for this process.

Generate QR Code

Web Portal

To start an enrollment using the QR code method we must first generate the QR code to be consumed by the client application (in our example we use a web app). This web application uses a UI to allow an enduser to register using a username and email address. Then uses these pieces of information in the API Call for /triggerEnroll.

Base URL

   www.awareid.aware-apis.com

Trigger Enroll

We initiate an enrollment by calling the /triggerEnroll endpoint with our received access token

  • username - required
  • email - required
  • notifyOptions - optional

Trigger Enroll

Our response for trigger enroll includes five pieces of information with the most relevant piece being the base64 encoded string of the QR that is used to be displayed to the user to continue the enrollment on their device.

With our QR code generated in our web application we then have to proceed with scanning the QR code and completing the enrollment. The following steps apply to enrolling a user from the client side application using a QR code. These steps include:

  1. Scan QR code and decrypt data.
  2. Get Public Key - Public Key for face data encryption
  3. Initiate an enrollment.
  4. Add device
  5. Enroll face

The QR Code will return a url with an encrypted data parameter named “data”.

This data has to be decrypted using the available public key. Once decoded 3 pieces of information are provided separated by “&”.

  1. Host url
  1. This URL is where all subsequent api calls will be made through
  1. The API Key
  1. This API Key is used in the header of api calls
  2. The key value pair in the header is as follows:

“apikey”:API_Key

  1. Session Token
  1. The session token is used to validate the session.

Enrollment Using QR Code Step 1 - Validate Session Token

The first api call necessary to enroll a user is /tokenVerify/validateSession.

Validate Session

   POST /tokenVerify/validateSession
   "Content-Type": 'application/json; charset=UTF-8',
   "apikey": apiKey

   {
       "sessionToken":sessionToken
   }

Authentication Workflow

Like the enrollment process we can also complete an authentication in two variations. The first is initiating the authentication from the client side and the second involves using a QR code scan to initiate the authencation process and using the client application to complete it. Below we explain how to achieve both options beginning with the Client Initiated Authentication

Client Initiated Authentication

A client initiated authentication is performed in 3 steps:

  1. Initiate authentication
  2. Verify device
  3. Verify face

Authentication Using QR Code

To authenticate by inititating through a QR code scan we first have to take in the authenticate details like first name, last name, email address and phone number and make a call to generate the QR code from a secondary application. In our demo we use a web app for this process.

Generate QR Code

Web Portal

To start an authentication using the QR code method we must first generate the QR code to be consumed by the client application (in our example we use a web app). This web application uses a UI to allow an enduser to register using a username and email address. Then uses these pieces of information in the API Call for /triggerAuthenticate .

Base URL

   www.awareid.aware-apis.com

Trigger Authenticate

We initiate an authenticate by calling the /triggerAuthenticate endpoint with our received access token

  • username - required
  • notifyOptions - optional

Trigger Authenticate

   POST baseUrl + /b2c/proxy/triggerAuthenticate
   Content-Type: 'application/json; charset=UTF-8',

   { "username": "[email protected]",
       "notifyOptions": {
           "notifyByPush": true

Our response for trigger authenticate includes five pieces of information with the most relevant piece being the base64 encoded string of the QR that is used to be displayed to the user to continue the authentication on their device.

With our QR code generated in our web application we then have to proceed with scanning the QR code and completing the authentication. The authentication workflow involves 4 steps:

  1. Scan QR code and decrypt data.
  2. Initiate authentication
  3. Verify device
  4. Verify face

The QR Code will return a url with an encrypted data parameter named “data”.

This data has to be decrypted using the available public key. Once decoded 3 pieces of information are provided separated by “&”.

  1. Host url
  1. This URL is where all subsequent api calls will be made through
  1. The API Key
  1. This API Key is used in the header of api calls
  2. The key value pair in the header is as follows:

“apikey”:API_Key

  1. Session Token
  1. The session token is used to validate the session.

Authentication Using QR Code Step 1 - Validate Session Token

The first api call necessary to authenticate a user is /tokenVerify/validateSession.

Validate Session

   POST /tokenVerify/validateSession
   "Content-Type": 'application/json; charset=UTF-8',
   "apikey": apiKey

   {
       "sessionToken":sessionToken
   }

Urlencoded

   This is the only call whose content type of this call is “application/x-www-form-urlencoded”
