Latest Patents

Czeskis holds a patent for a novel approach titled "Radio frequency identification secret handshakes." This invention defends RFID tags and contactless cards against ghost-and-leech attacks, also known as proxying, relay, or man-in-the-middle attacks. The system incorporates gesture recognition techniques that are directly implemented within the RFID tags or contactless cards. These tags or cards engage in wireless communications only when they detect 'secret handshakes' internally. The recognition system is implemented on a passive WISP RFID tag equipped with a built-in accelerometer. This approach is backward compatible with existing RFID tag and contactless card readers, minimizing changes to the current usage model of certain classes of RFID and contactless cards, such as access cards kept in wallets or purses. The execution of secret handshakes can occur without removing the card, thereby improving security and privacy properties in various applications, including contactless payment cards.
