Abstract
A data-carrying device and methods of authenticating the same are disclosed. The data-carrying device is described as being capable of communicating via the Near Field Communications (NFC) protocol and may have one or more NFC Data Exchange Format (NDEF) records stored in its memory. The data-carrying device also comprises or has the ability to generate a signature that proves the data-carrying device is the authorized device for storing the one or more NDEF records. A data-carrying device that attempts to transmit an NDEF record without a valid signature may be identified as an unauthorized data-carrying device.
Claims15
A method, comprising:
- receiving a first input at a data-carrying device that is storing one or more Near Field Communications (NFC) Data Exchange Format (NDEF) records;
- generating a signature for the one or more NDEF records, the data-carrying device using the first input to generate the signature;
- and
- providing the signature from the data-carrying device to a reading device so that the reading device can validate that the data-carrying device is authorized to store the one or more NDEF records.
A data-carrying device, comprising:
- a Near Field Communications (NFC) interface, which enables the data-carrying device to exchange NFC Data Exchange Format (NDEF) records with other NFC-enabled devices;
- and
- memory in which at least one NDEF record is stored along with a signature which provides proof that the data-carrying device is authorized to store the at least one NDEF record.
