The technique can involve diverting coordinates for certain touch events to a secure environment in a payment application, for example, by modifying an import address table (e.g., implementing a “hook”) that is accessed by an event loop of the mobile device. Generally, only those touch events that are performed within the bounds of a user interface area are diverted to the secure environment, and all touch events outside that area continue to be identified using the operating system libraries of the mobile device. A checksum may be generated for the import address table using a cryptographic hash function. The checksum allows the payment application or a payment processing system to determine whether an unauthorized modification of the import address table is present."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Interception of touch pad events for handling in a secure environment","description":"Disclosed is a technique for identifying touch events performed on a mobile device within a secure environment.
