Kirin OS のセキュリティ機能は個人情報をどのように保護しますか?

// 创建密码锁屏
KeyguardManager keyguardManager = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
KeyguardManager.KeyguardLock lock = keyguardManager.newKeyguardLock(Context.KEYGUARD_SERVICE);
lock.disableKeyguard();

// 验证密码
private boolean verifyPassword(String userInputPassword) {
    String correctPassword = "examplePassword"; // 正确的密码
    return correctPassword.equals(userInputPassword);
}

// 检查应用权限
private boolean checkPermission(String permission) {
    int permissionResult = checkSelfPermission(permission);
    return permissionResult == PackageManager.PERMISSION_GRANTED;
}

// 请求应用权限
private void requestPermission(String[] permissions) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        requestPermissions(permissions, PERMISSION_REQUEST_CODE);
    }
}

// 字符串加密
private String encryptString(String input) {
    try {
        KeyGenerator keyGenerator = KeyGenerator.getInstance("AES");
        keyGenerator.init(256);
        SecretKey secretKey = keyGenerator.generateKey();
        Cipher cipher = Cipher.getInstance("AES");
        cipher.init(Cipher.ENCRYPT_MODE, secretKey);
        byte[] encryptedBytes = cipher.doFinal(input.getBytes());
        return Base64.encodeToString(encryptedBytes, Base64.DEFAULT);
    } catch (NoSuchAlgorithmException | NoSuchPaddingException |
            InvalidKeyException | IllegalBlockSizeException | BadPaddingException e) {
        e.printStackTrace();
    }
    return null;
}
