Step 3: Collect the Device ID and DeviceDNA

You must now ensure that you now get the Device ID along with the DeviceDNA, as follows:

1. Ensure that on click of the Login (or Submit) button on the page, the following code snippet is called:

   <input type="button" value="Login" onClick="collectSystemInfo();">
   

2. Ensure that you have defined the collectSystemInfo() function. For example, you can use the following code snippet:

   function collectSystemInfo()
   {
     client.processDNA();
    
     var json = client.getDNA();
     var did = client.getDID();
   
     document.CollectMFPToEvaluate.DDNA = json;
     document.CollectMFPToEvaluate.DeviceID = did ;
   
     //post to server, both the DeviceDNA and Device ID values for risk eval
   
   }
   

3. After you have collected the DeviceDNA and the Device ID, as required, you must pass this collected information as input to evaluateRisk() method.
