Protect sensitive data

As with any third-party service, it’s important for you to understand and have the ability to manage what data is sent to Shake servers. Shake SDK allows you to filter out sensitive data on the mobile device itself, so it never reaches the Shake servers.

Automatically redacted sensitive data

Shake automatically redacts these sensitive data from your notifications, touch events and network requests:

  • email addresses
  • IP addresses
  • credit card numbers
  • bearer tokens

Shake also redacts network header values if the header key is:

  • password
  • secret
  • passwd
  • api_key
  • apikey
  • access_token
  • auth_token
  • credentials
  • mysql_pwd
  • stripetoken
  • Authorization
  • Proxy-Authorization
  • card[number]
  • token

To disable this privacy feature, use the method below:

App.kt
Shake.getReportConfiguration().isSensitiveDataRedactionEnabled = false

Views

Private views

You can mark any view as private, and it'll automatically be deleted from the auto screenshot. Private views are stored as a weak reference. They get cleared from the memory when not used anymore.

note

These methods won't delete sensitive views from auto screen recording — only from the auto screenshot.

Let's suppose you're building a shopping app and you want to delete the name and the credit card number views from the auto screenshot:

App.kt
import com.shakebugs.shake.Shake
import kotlinx.android.synthetic.main.activity_payment.*
private fun maskSensitiveData() {
Shake.addPrivateView(textName)
Shake.addPrivateView(textCardNumber)
}

To remove a view from private views use the following method:

App.kt
Shake.removePrivateView(view)

If you want to delete an entire screen from the auto screenshot, simply mark the whole activity as private:

App.kt
import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity
import com.shakebugs.shake.Shake
public class PaymentActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_payment)
Shake.addPrivateView(this)
}
...
}

To remove an activity from the list of private views, use the following method:

App.kt
Shake.removePrivateView(activity)

To clear all the private views, use the following method:

App.kt
Shake.clearPrivateViews()

Auto screen recording

Use the Android system flag FLAG_SECURE on an activity if you want to prevent sensitive data from being visible on the auto screen recording. It will make the activity black in the video:

App.kt
import android.os.Bundle
import android.view.WindowManager
import androidx.appcompat.app.AppCompatActivity
public class PaymentActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_payment)
window.setFlags(
WindowManager.LayoutParams.FLAG_SECURE,
WindowManager.LayoutParams.FLAG_SECURE)
}
...
}

Visit Auto screen recording to read how to turn it off altogether.

Jetpack Compose

In Jetpack Compose, the main building block of the UI is Composeable instead of View.

If you want to make a specific Composeable private, copy the following snippet into your project:

ShakePrivateView.kt
import androidx.compose.runtime.Composable
import androidx.compose.ui.platform.ComposeView
import androidx.compose.ui.viewinterop.AndroidView
import com.shakebugs.shake.Shake
@Composable
fun ShakePrivateView(content: @Composable () -> Unit) {
AndroidView(
factory = { context ->
ComposeView(context).apply {
Shake.addPrivateView(this)
setContent { content() }
}
}
)
}

Use ShakePrivateView Composeable as shown below:

MainActivity.kt
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
ComposeTestTheme {
Surface(color = MaterialTheme.colors.background) {
ShakePrivateView {
Greeting("Android")
}
}
}
}
}
}

In the example above, the Greeting component will be removed from the screenshots.

Touch events

Marking a view as private will automatically delete its touch events' text properties too. Consequently, you'll see them as data_redacted strings in ticket's Activity history. The view's ID, accessibility labels and tags remain visible.

Network requests

Network requests may contain sensitive data which you may not want to send to Shake servers. Use the Shake.setNetworkRequestsFilter() method to obfuscate sensitive parts of those requests, or to entirely prevent certain network requests from being logged. As an example, if you'd like to obfuscate the Authorization header in all network requests sent from your app, do this:

App.kt
import com.shakebugs.shake.Shake
private fun setupNetworkFilter() {
Shake.setNetworkRequestsFilter { networkRequest ->
val headers = networkRequest.requestHeaders
if (headers.containsKey("Authorization")) {
headers["Authorization"] = "***"
}
networkRequest
}
}

If you don't want to log specific network requests, return null from the NetworkRequestsFilter as shown below:

App.kt
import com.shakebugs.shake.Shake
private fun setupNetworkFilter() {
Shake.setNetworkRequestsFilter { networkRequest ->
if (networkRequest.url.startsWith("https://api.myapp.com/cards")) {
null
} else networkRequest
}
}

To clear the network requests filter, use Shake.setNetworkRequestsFilter(null).

Notification events

If your app notifications contain sensitive data, use the Shake.setNotificationEventsFilter() method to fully or partially obfuscate those notifications.

For example, if you'd like to obfuscate the description of the notification event that contains an email, do this:

App.kt
import com.shakebugs.shake.Shake
import com.shakebugs.shake.privacy.NotificationEventEditor
import com.shakebugs.shake.privacy.NotificationEventsFilter
private fun setupNotificationsFilter() {
Shake.setNotificationEventsFilter { notificationEvent ->
if (notificationEvent.title == "E-mail changed") {
notificationEvent.description = "***@gmail.com"
}
notificationEvent
}
}

If you do not want to track a specific notification event, return null from the NotificationEventsFilter like below:

App.kt
import com.shakebugs.shake.Shake
private fun setupNotificationsFilter() {
Shake.setNotificationEventsFilter { notificationEvent ->
if (notificationEvent.title == "E-mail changed") {
null
} else notificationEvent
}
}

To clear the notification events filter, use Shake.setNotificationEventsFilter(null).
