Verify Match: We compare the data in our identity graph with your data on a specific person to offer a risk score based on how well the information matches. Use matches to identify risk on a form field or credit card or loan application.
Verify Signal: Verify's signal data offers valuable insight into our confidence about a person's identity, activity, and risk level. Use these highly-specific and high-value signals to build and train your advanced IDV and fraud algorithms.
Verify Activity: Provides a numerical score to help you determine the legitimacy of a given data point. Long-term regular activity is a positive signal, and new, sporadic activity from a specific identifier is considered negative.
