Methods and system for passive authentication through user attributes
Data is automatically collected; the data relevant to user attributes. That data is provided as factors for passive authenticating the user for access to a device and/or a resource. In an embodiment, the data is used to establish a profile or a pattern for the user.
1. A method, comprising:
collecting, on a device, data relevant to attributes of a user;
passively authenticating the user based on the data by computing a value based on the data, wherein computing further includes chaining a first instance of a confidence calculator that executes on the device within a first processing environment with a second instance of the confidence calculator that executes on a second and different device within a second and different processing environment to produce the value by computing, by the first instance, a first portion of the value, providing, by the first instance, the first portion to the second instance as input data, computing, by the second instance, a second portion of the value from the first portion, and combining the first portion and the second portion as the value; and
automatically providing the user access to an electronic resource at a particular access level selected from a plurality of access levels based on a difference between a predetermined value and the value.
2. The method of claim 1 , wherein collecting further includes gathering the data during an automatically triggered interval of time.
3. The method of claim 2 , wherein gathering further includes starting the interval of time upon detection of a starting event and ending the interval of time upon detection of an ending event.
4. The method of claim 3 , wherein starting further includes identifying the starting event as initial handling by the user of a shopping apparatus and identifying the ending event as an initiation of a checkout transaction at a Point-Of-Sale (POS) terminal.
5. The method of claim 1 , wherein collecting further includes continuously gathering and updating the data when the user accesses one or more predefined resources executing on the device.
6. The method of claim 1 , wherein collecting further includes maintaining a profile or a pattern for the user based on the data.
7. The method of claim 6 , wherein maintaining further includes continuously updating the profile or the pattern based on new collected data relevant to the attributes of the user.
8. The method of claim 1 , wherein collecting further includes automatically collecting the data based on user operation of an apparatus to which the device is attached.
9. The method of claim 1 , wherein collecting further includes automatically collecting the data from sensors interfaced to the device.
10. The method of claim 9 , wherein automatically collecting further includes obtaining at least a portion of the data as a smell value from a smell sensor interfaced to the device.
11. The method of claim 9 , wherein automatically collecting further includes obtaining at least a portion of the data as activity data from an activity sensor interfaced to the device.
12. The method of claim 1 , wherein passively authenticating further includes automatically providing the data from the device to a passive authentication system at a Point-Of-Sale (POS) terminal during a checkout operation for a transaction being conducted by the user at the POS terminal.
