Abstract

The present disclosure is directed to embodiments for securely reconfiguring a media playback device. For example, a method may include determining whether a media playback device is being controlled by a user. In response to determining that the media playback device is not being controlled by the user, the method may further include: causing display of a pictograph that includes an encrypted payload with information for wirelessly connecting to the media playback device and is configured to be scanned by a client device; determining whether a request from the client device to wirelessly connect to the media playback device is a valid request; in response to the request being valid, wirelessly connecting the client device to the media playback device via a soft access point; and receiving, at the media playback device, information for reconfiguring the media playback device.

First claim

What is claimed is:

1 . A computer-implemented method comprising:
causing, by at least one processor, display of a pictograph via a media playback device, wherein the pictograph comprises an encrypted payload comprising:
information for connecting to the media playback device, and
a cryptographic certificate to identify the media playback device by a server;
receiving a request from a client device to connect to the media playback device, wherein the request includes a server-decrypted version of the information for connecting to the media playback device; determining that the request is valid; in response to determining that the request is valid, connecting the client device to the media playback device based on the server-decrypted version of the information; and receiving reconfiguration information for reconfiguring the media playback device.

2 . The computer-implemented method of claim 1 , wherein the reconfiguration information comprises wireless settings.

3 . The computer-implemented method of claim 1 , wherein causing the display of the pictograph is performed in response to determining that the media playback device completed an initial setup process.

4 . The computer-implemented method of claim 1 , wherein the encrypted payload further comprises account information of a user of the media playback device.

5 . The computer-implemented method of claim 1 , wherein the encrypted payload further comprises a network name and a passphrase.

6 . The computer-implemented method of claim 1 , wherein the cryptographic certificate comprises a public key associated with the media playback device.

7 . The computer-implemented method of claim 1 , wherein the pictograph comprises a quick response (QR) code.

8 . A system, comprising:
one or more memories; and at least one processor each coupled to at least one of the one or more memories and configured to perform operations comprising:
causing display of a pictograph via a media playback device, wherein the pictograph comprises an encrypted payload comprising:
information for connecting to the media playback device, and
a cryptographic certificate to identify the media playback device by a server;

receiving a request from a client device to connect to the media playback device, wherein the request includes a server-decrypted version of the information for connecting to the media playback device;
determining that the request is valid;
in response to determining that the request is valid, connecting the client device to the media playback device based on the server-decrypted version of the information; and
receiving reconfiguration information for reconfiguring the media playback device.

9 . The system of claim 8 , wherein the reconfiguration information comprises wireless settings.

10 . The system of claim 8 , wherein causing the display of the pictograph is performed in response to determining that the media playback device completed an initial setup process.

11 . The system of claim 8 , wherein the encrypted payload further comprises account information of a user of the media playback device.

12 . The system of claim 8 , wherein the encrypted payload further comprises a network name and a passphrase.

13 . The system of claim 8 , wherein the cryptographic certificate comprises a public key associated with the media playback device.

14 . The system of claim 8 , wherein the pictograph comprises a quick response (QR) code.

15 . A non-transitory computer-readable medium having instructions stored thereon that, when executed by at least one computing device, cause the at least one computing device to perform operations comprising:
causing display of a pictograph via a media playback device, wherein the pictograph comprises an encrypted payload comprising:
information for connecting to the media playback device, and
a cryptographic certificate to identify the media playback device by a server;
receiving a request from a client device to connect to the media playback device, wherein the request includes a server-decrypted version of the information for connecting to the media playback device; determining that the request is valid; in response to determining that the request is valid, connecting the client device to the media playback device based on the server-decrypted version of the information; and receiving reconfiguration information for reconfiguring the media playback device.

16 . The non-transitory computer-readable medium of claim 15 , wherein the reconfiguration information comprises wireless settings.

17 . The non-transitory computer-readable medium of claim 15 , wherein causing the display of the pictograph is performed in response to determining that the media playback device completed an initial setup process.

18 . The non-transitory computer-readable medium of claim 15 , wherein the encrypted payload further comprises account information of a user of the media playback device.

19 . The non-transitory computer-readable medium of claim 15 , wherein the encrypted payload further comprises a network name and a passphrase.

20 . The non-transitory computer-readable medium of claim 15 , wherein the cryptographic certificate comprises a public key associated with the media playback device.
