User authentication
User Authentication A mobile user authentication application is operable to perform one or more of the following operations: ⋅authenticate a user in a voice call to a telephony service, by passing an authentication code to the telephony service within the voice call [FIGS. 2, 2 c ]; ⋅validate a user instruction during a secure messaging session [FIG. 3 ]; and ⋅authenticate a user at a physical local service by obtaining a challenge code at that local service, validating the challenge code with a remote authentication service, obtain a confirmation code from the authentication service and presenting the confirmation code for validation at the local service [FIGS. 4, 4 a and 4 b ].
1. A method of user authentication by an application on a mobile telephony device, the method comprising the following steps executed by the application:
prior to initiating a telephone call to a remote telephony service, receiving authentication information from a user;
sending the authentication information to a remote authentication service;
when the authentication service identifies the user using the authentication information, receiving an authentication status from the authentication service including a call identifier, wherein the call identifier is a unique session identifier or includes a one-time passcode;
receiving separate data input by the user that identifies a purpose of the telephone call;
appending the separate data to the call identifier;
initiating the telephone call to a remote telephony service;
sending the call identifier with the appended separate data to the remote telephony service after the telephone call has been connected to the remote telephony service; and
after determining an authentication comparison match between the unique session identifier or the one-time passcode received in the initiated telephone call and an expected session identifier or an expected one-time passcode, the expected session identifier or the expected one-time passcode: (1) determined by the remote authentication service in response to the identification of the user using the authentication information, and (2) subsequently saved in a repository, receiving communications via the initiated telephone call from a telephone operator specific to the purpose of the telephone call and determined by routing the telephone call according to the appended separate data,
wherein the authentication comparison match is determined by the remote telephony service and verifies that the initiated telephone call was made by the user.
2. The method of claim 1 , wherein the user is verified by verbal validation within the telephone call.
3. The method of claim 2 , wherein the verbal validation comprises confirming data relating to the user.
4. The method of claim 3 , wherein the data relating to the user is confirmed by the remote authentication service.
5. The method of claim 1 , wherein the user is authenticated locally at the mobile telephony device by the interaction with the application, to receive the call identifier from the remote authentication service.
6. The method of claim 1 , wherein the call identifier is included as an audio signal within the telephone call.
7. A mobile device system for user authentication, the mobile device system comprising:
a processor;
a memory coupled to the processor; and
an application stored on the memory and executed by the processor, wherein the application is arranged to:
prior to initiating a telephone call to a remote telephony service, receive authentication information from a user;
send the authentication information to a remote authentication service;
when the authentication service identifies the user using the authentication information, receive an authentication status from the authentication service including a call identifier, wherein the call identifier is a unique session identifier or includes a one-time passcode;
receive separate data input by the user that identifies a purpose of the telephone call;
append the separate data to the call identifier;
initiate the telephone call to a remote telephony service;
send the call identifier with the appended separate data to the remote telephony service, after the telephone call has been connected to the remote telephony service; and
after determining an authentication comparison match between the unique session identifier or the one-time passcode received in the initiated telephone call and an expected session identifier or an expected one-time passcode, the expected session identifier or the expected one-time passcode: (1) determined by the remote authentication service in response to the identification of the user using the authentication information, and (2) subsequently saved in a repository, receive communications via the initiated telephone call from a telephone operator specific to the purpose of the telephone call and determined by routing the telephone call according to the appended separate data,
wherein the authentication comparison match is determined by the remote telephony service and verifies that the initiated telephone call was made by the user.
8. The method of claim 1 , wherein the user provides the separate data identifying the purpose of the telephone call without receiving any requests from the telephony service.
