title: Preventing data tampering on client/server application
body: <p>A bit of background info:</p>
  
  <ul>
  <li>I am building a geolocation based game for Android</li>
  <li>The server-side is coded in php</li>
  <li>Certain in-game actions requires the client application to send the current latitude and longitude to the server</li>
  </ul>
  
  <p>Is there any way to prevent the user from tampering with the location data being sent to the server?</p>
  
  <p>Please let me know if you need more information</p>
  
  <p>Thank you,</p>
  
  <p>EDIT: I understand there will be workaround to any security measure I implement, but how can I make it harder for users to modify the data being communicated to the server</p>
