TrustDevice-Android

A lightweight library for determining device uniqueness and risk identification.

Create a device identifier based on basic device information.

Will remain the same after uninstalling and reinstalling or clearing app data.

🪧Attention🪧:The functions of the basic version of github are relatively limited.

You can visit AWS Marketplace or TrustDecision to learn about our professional version.

Quick start

1. Add repository

Add these lines to your build.gradle.

allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
    }
}

If your version of Gradle is 7 or newer, add these lines to your settings.gradle:

repositories {
        ...
        maven { url 'https://jitpack.io' }
    }

2. Add dependency

Add these lines to build.gradle of a module.

dependencies {
    ...
    implementation 'com.github.trustdecision:trustdevice-android:1.0.8'
}

3. Get deviceInfo

DeviceInfo contains device id, risk information and device details.

3.1. Option 1

// initialization
TDRisk.init(context);

// usage
JSONObject deviceInfo = TDRisk.getBlackbox();
// Obtain deviceid and risk information through deviceInfo
String deviceID = deviceInfo.optString("device_id");
JSONObject deviceRisk = deviceInfo.optJSONObject("device_risk_label");
JSONObject deviceDetail = deviceInfo.optJSONObject("device_detail");

getBlackbox method executes in the calling thread and takes time to execute.

3.1.2. Option 2

TDRisk.Builder builder = new TDRisk.Builder();
builder.callback(new TDRiskCallback() {
    @Override
    public void onEvent(JSONObject deviceInfo) {
      	// Obtain deviceid and risk information through deviceInfo
        String deviceID = deviceInfo.optString("device_id");
        JSONObject deviceRisk = deviceInfo.optJSONObject("device_risk_label");
        JSONObject deviceDetail = deviceInfo.optJSONObject("device_detail");
    }
});
TDRisk.initWithOptions(context, builder);

callback is in a sub-thread, please do not perform UI operations.

Open Source Features

  • Basic device ID, This identifier is stable, it will remain the same even after uninstalling and reinstalling your app. But it will be different after factory reset of the device.
  • Basic equipment information, which can be used for simple data analysis
  • Basic risk identification ability
RiskLabel Risk Description
root Attackers will have higher privileges and can install many cheating software to affect the normal development of application business.
debug Applications can be modified by attackers at will, and the program will return unexpected values.
