Latest Patents

Sourav Das holds a patent for an "Offline interaction system and method using cryptography." This method involves a first device receiving an interaction request message from a second device, which includes an amount and a second device certificate. The first device verifies the second device certificate using a server computer public key. A trusted application within a secure element of the first device determines if the amount is less than an offline amount stored in the secure element. If it is, the trusted application updates the offline amount based on the transaction. The application then generates an interaction response message that includes the amount and a trusted application certificate, which is sent back to the second device.
