Device Intelligence Android Native

Device Fingerprinting helps you understand your user’s unique hardware with their device data. It efficiently syncs the data in the background, processes them and the data processed can be used to generate a fingerprint id.

Integration Overview

Integrate Android SDK in your application
Call the API to query device information

SessionKey and UserID is generated from client backend and sent to the SDK.
Invoke the submit function in SDK to pass the data to Bureau backend.
Upon successful transmission of the parameters, a callback is received in the SDK, based on the callback (Success/Failure) next steps can be taken.
If the callback is successful, Invoke Bureau's backend API /v1/suppliers/device-fingerprint to fetch the results.
Use the fingerprint and risk signals to allow, block or redirect the user to a desired flow.

Usage

The SDK is initialised in the client app and once the submit function is called the data relating to the user and device are automatically synced in the background.

Minimum Requirements

minSdkVersion 21
AndroidX

Getting Started

Add following lines in your root build.gradle

Properties properties  = new Properties()
properties.load(new FileInputStream(project.rootProject.file('local.properties')))
buildscript {
.....
}
allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io"}
    }
}

Add following lines in your module level build.gradle. The latest dependency can be obtained from here

dependencies {
//add the following dependency in your gradle file
implementation 'com.github.Bureau-Inc:prism-android-fingerprint-sdk:0.00.0'}

This library also uses some common android libraries. So if you are not already using them then make sure you add these libraries to your module level build.gradle

androidx.appcompat:appcompat:1.2.0

Initialise SDK

//Get SDK Instance with Client Id and Environment
val bureauAPI : BureauAPI  = BureauInstanceProvider.getBureauApiInstance(context,YOUR_CLIENT_ID,
                ENV_SANDBOX or ENV_PRODUCTION)

            bureauAPI.setSessionId(YOUR_SESSION_ID)
            
            bureauAPI.setFlow(YOUR_FLOW_NAME)//optional
            
            bureauAPI.setUserId(YOUR_USER_ID)

//Start collecting and submit data to Bureau's backend using the submit function
            bureauAPI.submit(object :
                DataCallback {
                override fun onError(errorMessage: ErrorResponse) {
                  
                }

                override fun onResult(message: SubmitResponse) {
                  
                }
            })

//Get SDK Instance with Client Id and Environment
BureauAPI bureauAPI = BureauInstanceProvider.getBureauApiInstance(context, "YOUR_CLIENT_ID", Environment.ENV_PRODUCTION);
bureauAPI.setSessionId("YOUR_SESSION_ID");  //Mandatory
bureauAPI.setFlow("your_flow_name");  //optional
bureauAPI.setUserId("your_user_id");  //optional


//Start collecting and submit data to Bureau's backend using the submit function
bureauAPI.submit((new DataCallback() {
   public void onError(@NotNull ErrorResponse errorMessage) {
       //implement your own logic
   }

   public void onResult(@NotNull SubmitResponse message) {
       //implement your own logic
   }
}));

Optional : Collect Behavioral Biometrics Data

After Initialization and before submit call below api . This needs to be called on the page where behavioral biometrics session data is needed. Once the user flow is completed, submit api needs to be called, for the session to end.

bureauAPI.startSession()

//Get SDK Instance with Client Id and Environment
BureauAPI bureauAPI = BureauInstanceProvider.getBureauApiInstance(context, "YOUR_CLIENT_ID", Environment.ENV_PRODUCTION);
bureauAPI.setSessionId("YOUR_SESSION_ID");  //Mandatory
bureauAPI.setFlow("your_flow_name");  //optional
bureauAPI.setUserId("your_user_id");  //optional


//Start collecting and submit data to Bureau's backend using the submit function
bureauAPI.submit((new DataCallback() {
   public void onError(@NotNull ErrorResponse errorMessage) {
       //implement your own logic
   }

   public void onResult(@NotNull SubmitResponse message) {
       //implement your own logic
   }
}));

Note:

To initialise the SDK we need to provide CREDENTIAL_ID.
Session Id is mandatory and unique for each submission.
To obtain the fingerprint Id query Bureau backend.
The default environment is production. If you want to run on UAT pass ENV_SANDBOX in getBureauApiInstance function.

Response returned from the SDK

The DataCallback added in the Submit function returns whether the device data has been registered or not.

object :DataCallback{
            override fun onError(errorMessage: ErrorResponse) {
               //Failure Callback
               Log.w(TAG,"Error "+errorMessage)
            }

            override fun onResult(message: SubmitResponse) {
                //Success Callback
                Log.w(TAG,"Success "+message)
            }
        }}

bureauAPI.submit((new DataCallback() {
   public void onError(@NotNull ErrorResponse errorMessage) {
       //implement your own logic
   }

   public void onResult(@NotNull SubmitResponse message) {
       //implement your own logic
   }
}));

Backend API Integration

Backend URL's

Sandbox - https://api.overwatch.stg.bureau.id/v1/suppliers/device-fingerprint
Production - https://api.overwatch.bureau.id/v1/suppliers/device-fingerprint

Authentication

API's are authenticated via an clientID and secret, they have to be base64 encoded and sent in the header with the parameter name as Authorisation.

Authorisation : Base64(clientID:secret)
