Authenticating with active stylus
First Claim
1. An apparatus comprising:
- a stylus comprising one or more electrodes operable to transmit signals wirelessly to a device through a touch sensor of the device;
one or more computer-readable non-transitory storage media within the stylus and embodying logic that is operable when executed to perform operations comprising;
accessing first data defining a gesture made with the stylus by a user, the gesture comprising a sequence of manipulations of the stylus while the stylus is not contacting any surface, the sequence of manipulations comprising a first manipulation occurring after a second manipulation;
accessing second data representing a pre-defined authentication sequence, the pre-defined authentication sequence comprising a first manipulation and a second manipulation, the first manipulation or the second manipulation of the pre-defined authentication sequence not forming one of a letter string, a number string, and a letter and number string; and
comparing, by the stylus, the first data with the second data to verify that the first manipulation and the second manipulation of the sequence of manipulations of the gesture defined by the first data occurs in a same order as the first manipulation and the second manipulation of the pre-defined authentication sequence represented by the second data and to;
authenticate the user to the stylus or the device,authenticate the stylus to the device or the user, orauthenticate the device to the stylus or the user.

Abstract
In one embodiment, a stylus includes electrodes operable to transmit signals wirelessly to a device through a touch sensor of the device. The stylus also includes one or more computer-readable non-transitory storage media within the stylus and embodying logic that is operable when executed to access first data representing a gesture made with the stylus by a user, such as a sequence of manipulations of the stylus. The logic is further operable to access second data representing a pre-defined authentication sequence and compare the first data with the second data. This comparison may authenticate the user to the stylus or the device, authenticate the stylus to the device or the user, or authenticate the device to the stylus or the user.

8. One or more computer-readable non-transitory storage media of a stylus embodying logic operable when executed to perform operations comprising:
-
accessing first data defining a gesture made with the stylus by a user, the gesture comprising a sequence of manipulations of the stylus while the stylus is not contacting any surface, the sequence of manipulations comprising a first manipulation occurring after a second manipulation; accessing second data representing an authentication sequence, the pre-defined authentication sequence comprising a first manipulation and a second manipulation, the first manipulation or the second manipulation of the pre-defined authentication sequence not forming one of a letter string, a number string, and a letter and number string; and comparing the first data with the second data to verify that the first manipulation and the second manipulation of the sequence of manipulations of the gesture defined by the first data occurs in a same order as the first manipulation and the second manipulation of the authentication sequence represented by the second data and to; authenticate the user to the stylus or the device; authenticate the stylus to the device or the user;
orauthenticate the device to the stylus or the user. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method comprising:
-
accessing, by one or more computer-readable non-transitory storage media of a stylus, first data defining a gesture made with the stylus by a user, the stylus comprising one or more electrodes operable to transmit signals wirelessly to a device through a touch sensor of the device, the gesture comprising a sequence of manipulations of the stylus while the stylus is not contacting any surface, the sequence of manipulations comprising a first manipulation occurring after a second manipulation; accessing, by the one or more computer-readable non-transitory storage media, second data representing a pre-defined authentication sequence, the pre-defined authentication sequence comprising a first manipulation and a second manipulation, the first manipulation or the second manipulation of the pre-defined authentication sequence not forming one of a letter string, a number string, and a letter and number string; and comparing, by the one or more computer-readable non-transitory storage media, the first data with the second data to verify that the first manipulation and the second manipulation of the sequence of manipulations of the gesture defined by the first data occurs in a same order as the first manipulation and the second manipulation of the pre-defined authentication sequence represented by the second data and to; authenticate the user to the stylus or the device; authenticate the stylus to the device or the user;
orauthenticate the device to the stylus or the user. - View Dependent Claims (16, 17, 18, 19, 20)
