安卓应用安全指南 5.5.1 处理隐私数据 示例代码
5.5.1 处理隐私数据 示例代码 原书：Android Application Secure Design/Secure Coding Guidebook 译者：飞龙 协议：CC BY-NC-SA 4.0 在准备应用的隐私政策时，你可以使用“协助创建应用隐私政策的工具” [29]。 这些工具以 HTML 格式和 XML 格式输出两个文件 - 应用隐私策略的摘要版本和详细版本。 这些文件的 HTML 和 XML 内容符合 MIC SPI 的建议，包括搜索标签等特性。 在下面的示例代码中，我们将演示此工具的用法，并使用由这个工具产生的 HTML 文件来展示程序隐私策略。 [29] http://www.kddilabs.jp/tech/public-tech/appgen.html 更具体地说，你可以使用以下流程图来确定使用哪个示例代码。 这里，“广泛同意”一词，指代广泛许可，由用户在应用的首次加载时，通过展示和查看程序隐私策略授予应用，用于应用将用户数据传输到服务器。 相反，短语“特定同意”指代在传输特定用户数据之前，立即获得的预先同意。 5.5.1.1 授予广泛同意和特定同意：包含应用隐私政策的应用 要点： 首次加载（或应用更新）时，获得广泛同意，来传输将由应用处理的用户数据。 如果用户未授予广泛同意，请勿传输用户数据。 在传输需要特别细致的处理的用户数据之前获得特定同意。 如果用户未授予特定同意，请勿传输相应的数据。 向用户提供可以查看应用隐私策略的方法。 提供通过用户操作删除传输的数据的方法。 提供通过用户操作停止数据传输的方法。 使用 UUID 或 cookie 来跟踪用户数据。 将应用隐私策略的摘要版本放置在素材文件夹中。 MainActivity.java package org.jssec.android.privacypolicy; import java.io.IOException; import org.json.JSONException; import org.json.JSONObject; import org.jssec.android.privacypolicy.ConfirmFragment.DialogListener; import com.google.android.gms.common.ConnectionResult; import com.google.android.gms.common.GooglePlayServicesClient; import com.google.android.gms.common.GooglePlayServicesUtil; import com.google.android.gms.location.LocationClient; import android.location.Location; import android.os.AsyncTask; import android.os.Bundle; import android.content.Intent; import android.content.IntentSender; import android.content.SharedPreferences; import android.content.pm.PackageInfo; import android.content.pm.PackageManager; import android.content.pm.PackageManager.NameNotFoundException; import android.support.v4.app.FragmentActivity; import android.support.v4.app.FragmentManager; import android.text.Editable; import android.text.TextWatcher; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.widget.TextView; import android.widget.Toast; public class MainActivity extends FragmentActivity implements GooglePlayServicesClient.ConnectionCallbacks, GooglePlayServicesClient.OnConnectionFailedListener, DialogListener { private static final String BASE_URL = "https://www.example.com/pp"; private static final String GET_ID_URI = BASE_URL + "/get_id.php"; private static final String SEND_DATA_URI = BASE_URL + "/send_data.php"; private static final String DEL_ID_URI = BASE_URL + "/del_id.php"; private static final String ID_KEY = "id"; private static final String LOCATION_KEY = "location"; private static final String NICK_NAME_KEY = "nickname"; private static final String PRIVACY_POLICY_COMPREHENSIVE_AGREED_KEY = "privacyPolicyComprehensiveAgreed"; private static final String PRIVACY_POLICY_DISCRETE_TYPE1_AGREED_KEY = "privacyPolicyDiscreteType1Agreed"; private static final String PRIVACY_POLICY_PREF_NAME = "privacypolicy_preference"; private static final int CONNECTION_FAILURE_RESOLUTION_REQUEST = 257; private String UserId = ""; private LocationClient mLocationClient = null; private final int DIALOG_TYPE_COMPREHENSIVE_AGREEMENT = 1; private final int DIALOG_TYPE_PRE_CONFIRMATION = 2; private static final int VERSION_TO_SHOW_COMPREHENSIVE_AGREEMENT_ANEW = 1; private TextWatcher watchHandler = new TextWatcher() { @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { boolean buttonEnable = (s.length() > 0); MainActivity.this.findViewById(R.id.buttonStart).setEnabled(buttonEnable); } @Override public void afterTextChanged(Editable s) { } }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Fetch user ID from serverFetch user ID from server new GetDataAsyncTask().execute(); findViewById(R.id.buttonStart).setEnabled(false); ((TextView) findViewById(R.id.editTextNickname)).addTextChangedListener(watchHandler); int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this); if (resultCode == ConnectionResult.SUCCESS) { mLocationClient = new LocationClient(this, this, this); } } @Override protected void onStart() { super.onStart(); SharedPreferences pref = getSharedPreferences(PRIVACY_POLICY_PREF_NAME, MODE_PRIVATE); int privacyPolicyAgreed = pref.getInt(PRIVACY_POLICY_COMPREHENSIVE_AGREED_KEY, -1); if (privacyPolicyAgreed <= VERSION_TO_SHOW_COMPREHENSIVE_AGREEMENT_ANEW) { // *** POINT 1 *** On first launch (or application update), obtain broad consent to transmit user data that will be handled by the application. // When the application is updated, it is only necessary to renew the user's grant of broad c onsent if the updated application will handle new types of user data.
