System and method for authentication across devices
An authentication approach simplifies the process of authentication across devices, while increasing security. An authentication code is supplied through non-traditional channels, such as audio and visual channels, allowing more complex codes to pass between two devices for authentication with increased security, while reducing user interaction.
1. A method, comprising:
providing, from a server to a second device of a user via a first connection, a request for authentication of the user with a service;
providing, from the server to a first device of the user via a second connection different than the first connection, a non-textual authentication code corresponding to the request for authentication of the user with the service; and
responsive to receiving, at the server and from the second device via the first connection, an indication that a signal corresponding to the non-textual authentication code was received by the second device from the first device via a non-network channel between the second device and the first device but not through the server, authenticating the user with the service, the non-network channel different than the first connection and the second connection.
2. The method of claim 1 , the non-network channel comprising an audio channel, the non-textual authentication code indicative of a sound.
3. The method of claim 1 , the non-network channel comprising a visual channel, the non-textual authentication code indicative of an image.
4. The method of claim 1 , the indication comprising a transformation of the non-textual authentication code.
5. The method of claim 1 , the request provided to the second device via a web page sent via the first connection.
6. The method of claim 5 , the non-textual authentication code provided to the first device via a multimedia messaging service message sent via the second connection.
7. The method of claim 5 , the non-textual authentication code provided to the first device via an app on the first device sent via the second connection.
8. A method, comprising:
providing, from a server to a second device of a user via a first connection, a request for authentication of the user with a service;
providing, from the server to the second device via the first connection, a non-textual authentication code corresponding to the request for authentication of the user with the service; and
responsive to receiving, at the server and from a first device of the user via a second connection different than the first connection, an indication that a signal corresponding to the non-textual authentication code was received by the first device from the second device via a channel between the first device and the second device but not through the server, authenticating the user with the service, the channel different than the first connection and the second connection.
9. The method of claim 8 , the channel comprising an audio channel, the non-textual authentication code indicative of a sound.
10. The method of claim 8 , the channel comprising a visual channel, the non-textual authentication code indicative of an image.
11. The method of claim 8 , the indication comprising a transformation of the non-textual authentication code.
12. The method of claim 8 , the request provided to the second device via a web page sent via the first connection.
13. The method of claim 8 , the non-textual authentication code provided to the second device via a web page sent via the first connection.
14. The method of claim 8 , the indication received from the first device via an app on the first device.
15. An information processing system for authentication across devices, comprising:
a processor device; and
memory comprising computer-executable instructions that when executed by the processor device perform acts comprising:
receiving, at a second device of a user and from a server via a first connection, a request for authentication of the user to access first information;
at least one of:
receiving, at the second device and from a first device of the user via a channel between the second device and the first device but not through the server, a signal corresponding to a non-textual authentication code corresponding to the request for authentication of the user, and providing, from the second device to the server via the first connection, an indication that the signal was received; or
receiving, at the second device and from the server via the first connection, the signal corresponding to the non-textual authentication code and providing the signal from the second device to the first device via the channel but not through the server; and
accessing the first information, via the first connection, based upon the receiving the signal or the providing the signal, the channel different than the first connection.
16. The information processing system of claim 15 , the channel comprising an audio channel, the non-textual authentication code indicative of a sound.
17. The information processing system of claim 15 , the channel comprising a visual channel, the non-textual authentication code indicative of an image.
18. The information processing system of claim 15 , the acts comprising providing a request to access the first information to the server via the first connection.
19. The information processing system of claim 15 , the acts comprising receiving, at the second device and from the first device of the user via the channel between the second device and the first device but not through the server, the signal corresponding to the non-textual authentication code corresponding to the request for authentication of the user.
20. The information processing system of claim 15 , the acts comprising receiving, at the second device and from the server via the first connection, the signal corresponding to the non-textual authentication code and providing the signal from the second device to the first device via the channel but not through the server.
