First Claim
1. A method for registering wireless smart devices for secure offline data transfer, the method comprising:
- for an application configured to execute on a wireless smart device and that requires access to information regarding an account that does not reside on the wireless smart device;
sending a registering message, to a server having access to the information regarding the account, a first wireless smart device as an account owner device (AOD) for operating in an online mode for obtaining the information regarding the account from the server and for operating in an offline mode for transferring the information regarding the account to at least one additional device via a secure offline data transfer using near field communications (NFC), wherein the registering message includes a designation by the owner of the account identification of the first wireless smart device as AOD, identification of the application and identification of the at least one additional device as account sharer devices (ASDs) associated with the first wireless smart device;
in response to registering the first wireless smart device as the account owner device, granting, at the server, only the first wireless smart device access to the account information from the server;
sending another registering message, to the server, using the at least one second wireless smart device as an account sharer device (ASD) for operating in the offline mode for receiving the information regarding the account from the first wireless smart device only via the secure offline data transfer using NFC from the first wireless device;
in response to registering using the first wireless smart device and the at least second wireless smart device, the server transmitting a master key to the first wireless smart device and a diversified key that is different from the master key to the second wireless smart device to enable secure offline communication using NFC; and
in response to registering the at least one second wireless smart device as the account sharer device, preventing, at the server, the at least one second wireless smart device from accessing the information regarding the account via the online mode, wherein preventing the at least one second wireless smart device from accessing the information regarding the account via the online mode does not prevent the at least one second wireless smart device from receiving the information regarding the account from the first wireless smart device via the secure offline data transfer using NFC.
