Sample Code Reference

The following sample code illustrates how to implement RiskMinder’s DeviceDNA and Device ID collection mechanism. It showcases the collection logic in one file (say, index.jsp). However, you can implement appropriate code snippets in different pages, depending on the number of pages you show before you call the evaluateRisk() method.
