Abstract
Techniques for ascertaining legitimacy of communications received during a digital interaction with a client device. The techniques include: receiving a communication; identifying from the communication a first secured token; processing the first secured token by: obtaining, from the first secured token, information indicating a state of the digital interaction; and using the information indicating the state to determine whether the communication is from the client device; and when it is determined that the communication is from the client device, causing at least one action responsive to the communication to be performed; updating the information indicating the state of the digital interaction to obtain updated information indicating the state of the digital interaction; and providing a second secured token to the client device for use in a subsequent communication during the digital interaction, the second secured token comprising the updated information indicating the state of the digital interaction.
