Abstract
In one embodiment, a stylus operable to communicate wirelessly with a device through a touch sensor of the device contains one or more computer-readable non-transitory storage media embodying logic that is operable when executed to access first data representing a recently occurred authentication event involving the stylus or the device. The logic is further operable to access second data representing a pre-defined authentication event. The logic is further operable to compare the first data with the second data to authenticate a user to the stylus or the device, a stylus to the user or the device, or a device to the user or the stylus.
Claims20
An apparatus comprising:
- a stylus comprising one or more electrodes for transmitting 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 representing a recently occurred authentication event involving the stylus or the device;
- accessing second data representing a pre-defined authentication event;
- comparing the first data with the second data;
- and
- based on the comparison, determining an access level from a first access level and a second access level, the first access level and the second access level each requiring authentication, the first access level enabling access to a plurality of actions, the second access level enabling access to a subset of the plurality of actions, the plurality of actions comprising:
- reading data on the stylus or the device;
- writing data on the stylus or the device;
- and
- accessing administrative or security settings on the stylus or the device.
One or more computer-readable non-transitory storage media on or in a stylus and embodying logic operable when executed to perform operations comprising:
- accessing first data representing a recently-occurred authentication event involving a stylus or a device, the stylus comprising one or more electrodes operable to transmit signals wirelessly to the device through a touch sensor of the device;
- accessing second data representing a pre-defined authentication event;
- comparing the first data with the second data;
- and
- based on the comparison, determining an access level from a first access level and a second access level, the first access level and the second access level each requiring authentication, the first access level enabling access to a plurality of actions, the second access level enabling access to a subset of the plurality of actions, the plurality of actions comprising:
- reading data on the stylus or the device;
- writing data on the stylus or the device;
- and
- accessing administrative or security settings on the stylus or the device.
A method comprising:
- accessing, by a stylus, first data representing a recently-occurred authentication event involving the stylus or a device, the stylus comprising one or more electrodes operable to transmit signals wirelessly to the device through a touch sensor of the device;
- accessing, by the stylus, second data representing a pre-defined authentication event;
- comparing, by the stylus, the first data with the second data;
- and
- based on the comparison, determining an access level from a first access level and a second access level, the first access level and the second access level each requiring authentication, the first access level enabling access to a plurality of actions, the second access level enabling access to a subset of the plurality of actions, the plurality of actions comprising:
- reading data on the stylus or the device;
- writing data on the stylus or the device;
- and
- accessing administrative or security settings on the stylus or the device.
