Fingerprint Hardware Download For Android

/ Comments off

Are you using latest version of android? Yes, Then use Android’s latest feature Fingerprint authentication. Only your have authorisation to access your own phone and app. After release of Android 6.0 Marshmallow android has released fingerprint secured authentication, Which allow you to secure your app and phone. It’s also called as biometric authentication.

It’s very Fast and Dependable way of authenticating user’s identity
- Nowadays all the payment apps are using fingerprint access to allow you send payment and receive payment.
- It’s very secured so it can not allow any other person’s fingerprint identity to access your phone and payment app.
- To implement this functionality in your app if you do not have Marshmallow version 6.0 than you have to download from Android SDK.
- It will not accessible in non-fingerprint support smartphone.

Steps to enable fingerprint in your smartphone.

The Android framework includes face and fingerprint biometric authentication. Android can be customized to support other forms of biometric authentication (such as Iris). All biometric implementations must meet security specifications and have a strong rating in order to participate in the BiometricPrompt class. If you marked android.hardware.fingerprint as something that your app requires (android:required=”true”) then you don’t need to perform this check. The user has granted your app permission. Download Screen Lock Pro - Fingerprint, Smart lock, IRIS apk for Android. Screen Lock Pro, the Smart screen off and lock app with professional Animation. The latest beta update version 20.11.23 offers a few upgrades and improvements for the Android 11 MIUI 12 update. Xiaomi is rolling out MIUI 12 Global Stable update for Redmi Note 7 and Redmi Note.

- Your device should have fingerprint scanner which can authenticate your thumb or finger.
- Device should be compatible with android Marshmallow version 6.0.
- You have to set your device lock screen as password, pin or pattern and you have to add at least single fingerprint.

Steps for implementation via programming.
Create new Project in Android Studio
1. Create a new project in Android Studio from File ⇒ New Project and set the minimum SDK version to Android 6.0 (API 23).
2. Without permission it won’t allow you to start your app so first of all you have to add permission in AndroidManifest.xml file.
- App also need to add permission to add feature of touch sensor in order to access finger touch.
- App will check that your device has registered fingerprint or not if not then it will give message that please add at least one fingerprint in your smartphone.

Create fingerprint authentication part.

You have to check that your device has software,hardware settings to access fingerprint authentication.

Initialize both Android KeyguardManager and FingerprintManager.

KeyguardManager keyguardManager = (KeyguardManager) getSystemService(KEYGUARD_SERVICE);
FingerprintManager fingerprintManager = (FingerprintManager) getSystemService(FINGERPRINT_SERVICE);

If your device support both this conditions than you are now accessible to use fingerprint authentication.

To perform this authentication we have to create key,cipher and cryptoobject.

Below code will give you access to gain keystore instance which allows you to store cryptographic keys.

- Initialize empty keystore
- Initialize keyGenerator
try {
keyStore = KeyStore.getInstance('AndroidKeyStore');
} catch (Exception e) {
e.printStackTrace();
}

KeyGenerator keyGenerator;
try {
keyGenerator = KeyGenerator.getInstance(KeyProperties.KEY_ALGORITHM_AES, 'AndroidKeyStore');
} catch (NoSuchAlgorithmException NoSuchProviderException e) {
throw new RuntimeException('Failed to get KeyGenerator instance', e);
}

try {
keyStore.load(null);
keyGenerator.init(new
KeyGenParameterSpec.Builder(KEY_NAME,
KeyProperties.PURPOSE_ENCRYPT
KeyProperties.PURPOSE_DECRYPT)
.setBlockModes(KeyProperties.BLOCK_MODE_CBC)
.setUserAuthenticationRequired(true)
.setEncryptionPaddings(
KeyProperties.ENCRYPTION_PADDING_PKCS7)
.build());
keyGenerator.generateKey();
} catch (NoSuchAlgorithmException
InvalidAlgorithmParameterException
CertificateException IOException e) {
throw new RuntimeException(e);
}

cryptoObject = new FingerprintManager.CryptoObject(cipher);
Helper helper = new FingerprintHandler(this);
helper.startAuth(fingerprintManager, cryptoObject);

Create FingerPrintHandler class to access FingerprintManager Authentication
- onAuthenticationFailed() it will called when your authentication is incorrect or not match.
- onAuthenticationError(int errMsgId, CharSequence errString) it will called if there is any kind of fatal error.
- onAuthenticationSucceeded(FingerprintManager.AuthenticationResult result) it will called when your fingerprint is correct or successfully authorized.
- onAuthenticationHelp(int helpMsgId, CharSequence helpString) This method can give additional information regarding fingerprint authentication.

FingerprintHandler.java file
public class FingerprintHandler extends FingerprintManager.AuthenticationCallback {

How to run app in your device and emulator
- To test the app, it is possible to use a real device that has a touch sensor. Anyway, it is possible to test the app in the emulator too.
- To use this app in Android emulator you have to configure it
- Your device should be compatible of Marshmallow 6.0 version.
- If your device do not have registered of fingerprint it will show you message as per first screen
- If your fingerprint does not match it will show your incorrect fingerprint message Animals martin garrix download mp3.

WireGuard is a next generation secure network tunnel protocol. This application allows users to connect to WireGuard tunnels. More information may be found on the project webpage.

If your device has a custom kernel containing the WireGuard module, then the module will be used for superior battery life and performance. Otherwise a userspace version will work sufficiently on all other devices.
