Integration Requirement

Compliance Explanation

Please note that when integrating SDK products provided by the TrustDecision in the APP of your company:

1.1 According to the user's information protection regulations, before your users start the App for the first time and start collecting information, your company should fully inform the user of the purpose, method, and scope of collecting, using, and sharing the user's personal information with a third party through an interactive interface or design (such as a pop-up window of the privacy policy), and obtain the express consent of the end user.

1.2 To provide business security and risk control services to your company, the TrustDecision SDK will collect, process, and use the identification information（IMEI/IDFA）, AndroidID, IMSI, MEID, MAC address, SIM card serial number, device type, device model, system type, geographical location, login IP address, application list, running process, sensor information(light sensor, gravity sensor, magnetic field sensor, acceleration sensor, gyroscope sensor) and other device information of the user's device. To ensure compliance with your use of related services, the aforementioned privacy policy should cover the authorization of TrustDecision SDK to provide services and collect, process, and use relevant information. The following terms are for your reference. The specific expression can be determined by your company according to the overall framework and content of your privacy agreement:

Privacy Protocol: https://www.trustdecision.com/legal/privacy-policy

Integration Steps

SDK Integration

Add warehouse

First, please add the maven library configuration to build.gradle in the project root directory

allprojects {
    repositories {
        ...
        mavenCentral()
    }
}

If your Gradle version is 7 or higher, add these lines to your settings.gradle

repositories {
        ...
        mavenCentral()
}

Add Dependencies

Add dependencies to app/build.gradle of the project, as shown below:

dependencies {
    // Device Fingerprint
    implementation 'com.trustdecision.android:mobrisk:4.3.2.8'
    // Liveness Detection
    implementation 'com.trustdecision.android:liveness:2.2.3'
 }

If you encounter compliance issues, you can exclude the collection of relevant modules during the dependency phase, as follows:

dependencies {
    // Device Fingerprint
    implementation('com.trustdecision.android:mobrisk:4.3.2.8'){
				// after removal, sdk does not get the list of installation packages
        exclude group: 'com.trustdecision.android', module: 'packagelist'
				// after removal, sdk will not collect READ_PHONE_STATE related information
        exclude group: 'com.trustdecision.android', module: 'readphone'
				// after removal, sdk will not collect location information
        exclude group: 'com.trustdecision.android', module: 'location'
				// after removal, sdk will not collect sensor information
        exclude group: 'com.trustdecision.android', module: 'sensor'
				// after removal, sdk will not collect wifi information
        exclude group: 'com.trustdecision.android', module: 'wifiinfo'
    }
 }

ABI Type

The SDK currently supports two ABI types: armeabi-v7a, arm64-v8a. It is recommended that the accessor party add an abiFilters configuration to select the required architecture type in the app/build.gradle file. For Example:

defaultConfig {
    ........
    ndk {
        abiFilters 'armeabi-v7a', 'arm64-v8a'
    }
}

For the specific architecture, please refer to the architecture you need to support!

AndroidManifest.xml

Declare the following permissions in the AndroidManifest.xml file under the application module

XML

<manifest>
   <!-- required -->
   <uses-permission android:name="android.permission.INTERNET"/>
   <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
   <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
  <!-- Outside the Chinese Mainland -->
  <uses-permission android:name="com.google.android.gms.permission.AD_ID"/>

   <!--optional, If not declared, some device information will be abandoned -->
   <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
   <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
   <uses-permission android:name="android.permission.READ_PHONE_STATE" />
   <!-- required for Android 11 and above to obtain the installed packages -->
   <uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"
        tools:ignore="QueryAllPackagesPermission" />
</manifest>

How to use the SDK

Precautions

• Ensure that the SDK is initialized after the user agrees to the privacy agreement, so as to avoid the occurrence of SDK initialization and collection without the user's consent to the privacy agreement, which may cause compliance risks.

SDK Configuration

The Trustdecision SDK uses the TDRisk.Builder method to configure and set the SDK initial parameters, and provides the setting results as initialization parameters to the SDK initialization method initWithOptions().

TDRisk.Builder required parameters

initWithOptions method Optional Parameter, see the attached table for details (list of optional parameters for initial configuration)

Best Practices

1. Call initialization in the onCreate method of the application, and obtain blackBox asynchronously

// onCreate of APPlication
TDRisk.Builder builder = new TDRisk.Builder()
/*************************** required  ***************************/
.partnerCode("demo")        // get from our customer platform
.partnerKey("key")          // get from our customer platform		
.appKey("appKey")           // get from our customer platform		 
.country(TDRisk.COUNTRY_SG);

if(agrees to the privacy){
  TDRisk.initWithOptions(getApplicationContext(), builder);
  TDRisk.getBlackBox(new TDRiskCallback() {
  	@Override
  	public void onEvent(String blackbox) {
    	// here is in a new thread
    	Log.i("TD", "init & get success");
  }
});
}

1. Obtain blackBox in actual business scenarios

public void register() {
  ...
  String blackBox = TDRisk.getBlackBox();
  ...
}

Status Check

1. Log will be printed in logcat while initialization successfully

TD_JAVA: Tongdun sdk load success
TD_JAVA: Tongdun sdk init success

2. getBlackBox() will return a 26-bit string while initialization successfully: rGPGX1678775227I9NCwcuVJCb。

3. getBlackBox() will return a string of around 5000 bits while initialization Failed, please refer to overview-definition

Get SDK Version

Sample Code

// Get SDK Version
TDRisk.getSDKVersion();

Other Instructions

Confuse packaging. If the developer needs to use Proguard for confusion, please add the following code to the proguard configuration file:

#trustdecision
-keep class com.trustdecision.**{*;}
-keep class cn.tongdun.**{*;}

Liveness Detection Module

Initial configuration optional parameter list

Start liveness detection

TDRisk.showLiveness to start liveness detection

TDShowLivenessCallback is the callback interface for the retrieval of liveness detection results and the sample codes as follows:

...
public void loginClick() {
  TDRisk.showLiveness(new TDRiskLivenessCallback() {
      @Override
      public void onSuccess(String result) {
        Log.d("TD","Verification succeeded" + result);
      }

      @Override
      public void onError(String errorCode, String errorMsg, String sequenceId) {
        Log.d("TD","Verification failed!, Error code:"+ errorCode + ", Error message:" + errorMsg + ", seqid: " + sequenceId);
      }
  });
}
