The method comprises receiving the first set of authentication data from the portable consumer device, the portable consumer device comprising a sensor configured to observe one or more events, a memory comprising a first set of authentication data, an alteration module with instructions for altering the first set of authentication data and a processer configured to execute the instructions for altering the first set of authentication data when the sensor observes the one or more events. The method further comprises comparing the first set of authentication data with a second set of authentication data, determining if the first set of authentication data complies with an expected change in authentication data from the second set of authentication data and sending an authentication response accordingly."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Observable moment encryption","description":"A method for authenticating a portable consumer device is disclosed.
