AUTHENTICATION VIA A DEVICE
The claimed subject matter provides a system and/or a method that facilitates authentication of a user in a surface computing environment. A device or authentication object can be carried by a user and employed to retain authentication information. An authentication component can obtain the authentication information from the device and analyze the information to verify an identity of the user. A touch input component can ascertain if a touch input is authentication by associating touch input with the user. In addition, authentication information can be employed to establish a secure communications channel for transfer of user data.
1 . A system that facilitates authentication of a user in a surface computing environment, comprising:
an authentication component that obtains authentication information from at least one device uniquely associated with a user, the authentication component determines an identity of the user based at least in part on the authentication information; and
a touch input component that associates a touch input with the user to ascertain if the touch input is authenticated.
2 . The system of claim 1 , the touch input component associates the touch input with the user based at least in part on a location of the device and a location of the touch input on a surface in the surface computing environment.
3 . The system of claim 2 , the touch input component determines the location of the device based upon a visual observation of the device placed on the surface.
4 . The system of claim 3 , the touch input component generates an authenticated region on the surface around the device placed on the surface.
5 . The system of claim 4 , the touch input component associates touch input within the region with the user uniquely associated with the device placed on the surface.
6 . The system of claim 1 , the touch input component obtains touch input that includes a signal modulated with the authentication information from the at least one device.
7 . The system of claim 6 , the touch input component extracts the authentication information from the touch input and matches the extracted information to information obtained by the authentication component.
8 . The system of claim 7 , the touch input component associates touch input with the user associated with the at least one device upon successful matching of information.
9 . The system of claim 6 , the authentication component obtains authentication information from the at least one device via a capacitively coupled electrical signal modulated with the information.
10 . The system of claim 6 , the authentication component obtains authentication information from the at least one device via a visible signal modulated with the information.
11 . The system of claim 1 , the authentication component obtains authentication information from the at least one device via a vibration pattern modulated with the information.
12 . The system of claim 1 , the authentication component obtains authentication information from the at least one device via textual input.
13 . The system of claim 1 , the authentication component obtains authentication information from the at least one device via a near field communication channel.
14 . The system of claim 1 , the authentication component employs the obtained authentication information to create a secure communication channel between a surface in the surface computing environment and the at least one device.
15 . The system of claim 1 , wherein a color is assigned to the user such that visual feedback in the assigned color informs the user that touch points are authenticated.
16 . The system of claim 1 , the at least one device is a mobile device.
17 . A method that facilitates authenticated interactions with surface computing equipment in a surface computing environment, comprising:
obtaining authentication information from at least one authentication object uniquely coupled to a user;
analyzing the authentication information to ascertain and verify an identity of at least one of the user or the authentication object; and
employing at least one of the authentication information or location of the authentication object relative to a surface of the surface computing equipment to authenticate touch input received by the surface.
18 . The method of claim 17 , further comprising establishing a secure communication channel between the authentication object and the surface computing equipment.
19 . The method of claim 17 , further comprising generating an authenticated region around the authentication object placed on the surface of the surface computing equipment.
20 . A system that enables authentication of a user in a surface computing environment via a device, comprising:
means for receiving authentication information from at least one device carried by a user;
means for verifying an identity of the user based at least in part on the received authentication information;
means for transferring user data to a surface in the surface computing environment; and
means for associating touch point with at least one of the device or the user.
