Abstract

Apparatuses for peer-to-peer network setup are presented. In one embodiment, an apparatus comprises a wireless processing unit to communicate with a master device. The wireless processing unit is operable to receive encoded data in a two-dimensional (2D) barcode. The encoded data comprise at least user information associated with the master device including a user identifier, a device identifier, or both. The encoded data further comprise network information including a network identifier, a password, and a profile lifetime value. In one embodiment, the apparatus further comprises a display unit to display at least part of the user information and the network information to a user. The wireless processing unit is operable to initiate a peer-to-peer network setup with the master device based at least on a response from the user.

First claim

What is claimed is:

1. A network apparatus comprising:
a hardware processor to communicate with a first master device, receive an image associated with a user of the first master device and receive encoded data in a two-dimensional (2D) barcode, wherein the encoded data comprise at least user information associated with the first master device including a user identifier, a device identifier, or both; and
network information including a network identifier, a password, and a profile lifetime value, wherein the password is a share secret among three or more devices of a peer-to-peer network if the peer-to-peer network is fully connected rather than a star topology peer-to-peer network; and
a display unit operable to display at least part of the user information and the network information encoded in the 2D barcode to a first user and the image for the user to verify an identity of the first master device, wherein the processor is operable to initiate a peer-to-peer network setup with the first master device based at least on a response from the first user verifying the network information encoded in the 2D barcode.

2. The network apparatus of claim 1 , wherein the processor is operable to receive an image associated with the first master device.

3. The network apparatus of claim 2 , wherein the processor is capable of receiving the barcode from a camera image.

4. The network apparatus of claim 2 , wherein the processor is capable to receive the user information via non-secured communication.

5. The network apparatus of claim 4 , wherein the peer-to-peer network setup is initiated without the first user remembering the password.

6. The network apparatus of claim 4 , wherein the peer-to-peer network setup is initiated without the first user entering the password manually, wherein the password comprises one or more characters that are not limited to characters which the first user is able to enter.

7. The network apparatus of claim 4 , wherein the processor is operable to store the network information based at least on the first user's preference and the profile lifetime value.

8. The network apparatus of claim 4 , wherein the user information associated with the first master device is used for an identification purpose instead of a physical IP address.

9. A computer implemented method comprising:
receiving encoded data in a two-dimensional (2D) barcode generated by a first master device, wherein the encoded data comprise at least user information
associated with the first master device including a user identifier, a device identifier, or both, and network information including network identifier, a password, and a profile lifetime value, wherein the password is a share secret among three or more devices of a peer-to-peer network if the peer-to-peer network is fully connected rather than a star topology peer-to-peer network;
displaying at least part of the user information and network information encoded in the 2D barcode to a first user; and
initiating a peer-to-peer network setup with the first master device based at least on a response from the first user verifying the network information encoded in the 2D barcode.

10. The computer implemented method of claim 9 , further comprising:
receiving an image associated with the first master device or a user of the first master device; and
displaying the image for the first user to verify an identity of the first master device.

11. The computer implemented method of claim 9 , further comprising receiving the barcode from a camera image.

12. A non-transitory computer readable medium having a computer program which when executed causes a processor to:
receive encoded data in a two-dimensional (2D) barcode generated by a first master device, wherein the encoded data comprise at least user information associated with the first master device including a user identifier, a device identifier, or both; and network information including a network identifier, a password, and a profile lifetime value, wherein the password is a share secret among three or more devices of a peer-to-peer network if the peer-to-peer network is fully connected rather than a star topology peer-to-peer network;
receive an image associated with a user of the first master device;
display at least part of the user information and the network information encoded in the 2D barcode to a first user;
display the image for the user to verify an identity of the first master device; and initiate a peer-to-peer network setup with the first master device based at least on a response from the first user verifying the network information encoded in the 2D barcode.

13. The computer readable medium of claim 12 having a computer program which when executed further causes the processor to:
receive an image associated with the first master device or a user of the first master device; and
display the image for the first user to verify an identity of the first master device.

14. The computer readable medium of claim 12 having a computer program which when executed further causes the processor to receive the barcode from a camera image.
