Secure registration of a mobile device for use with a session

A non-transitory computer-readable medium embodying a computer program for registering a mobile device with an entity, the computer program comprising computer-readable program code for:

• identifying, using the mobile device, a registration identifier from a first message received from the entity via a first communication path associated with a current session between a user and the entity via a data processing system associated with the user in response to a request to register the mobile device as being associated with the user to enable use of the mobile device for a future action associated with an account of the user with the entity, the mobile device not previously registered with the entity as being associated with the user;
• sending, by the mobile device via a second communication path including a wireless communication link, a second message including at least one of the registration identifier and a function of the registration identifier to a data processing system associated with the entity for registration of the mobile device as being associated with the user;
• and
• storing, by the mobile device, a public key associated with the entity for use of the mobile device with the future action associated with the account based on association of the mobile device with the user, the public key received from the entity in the first message or another message,
• wherein the mobile device is associated with the user based on the at least one of the registration identifier and the function of the registration identifier in the second message being identical to at least one of the registration identifier and a function of the registration identifier in the first message.

A non-transitory computer-readable medium embodying a computer program for registering a mobile device as being associated with a user with an entity, the computer program comprising computer-readable program code for:

• at least one of (i) identifying, by a data processing system associated with a third party, a first registration identifier from a first message received from the entity and (ii) generating the first registration identifier and sending, by the data processing system associated with the third party, the generated first registration identifier to the entity for delivery to the user via a first communication path associated with a current session between the user and the entity via a data processing system associated with the user;
• receiving, by the data processing system associated with the third party, a second message from the mobile device via a second communication path including a wireless communication link, the second message including a second registration identifier;
• associating, by the data processing system associated with the third party, the mobile device with the user based on the second registration identifier being identical to at least one of the first registration identifier and a function of the first registration identifier;
• and
• sending a third message to the entity for registering the mobile device as being associated with the user to enable use of the mobile device for a future action associated with an account of the user with the entity in response to the second registration identifier being identical to the at least one of the first registration identifier and the function of the first registration identifier, the mobile device not previously registered with the entity as being associated with the user.
