User identification with input profile record

A method for user identification, the method comprising:

• receiving, with the electronic processor, a plurality of input profile records (IPRs) associated with a first user, the plurality of input profile records each based on a plurality of user inputs and indicative of identity of the first user;
• controlling, with the electronic processor, a memory to store the plurality of IPRs in an input profile record repository;
• receiving, with the electronic processor, a current IPR associated with a second user;
• determining, with the electronic processor, whether the second user is the first user by comparing a first one or more biometric features based on the plurality of IPRs and a second one or more biometric features based on the current IPR;
• and
• responsive to determining that the second user is the first user, outputting, with the electronic processor, an identity confirmation that the second user is the first user.

The method of 8, wherein the first one or more biometric features and the second one or more biometric features each include a plurality of sensor features including two or more of:

• average sensor value for each axis,
• median sensor value for the each axis,
• mean to median sensor value ratio for the each axis,
• standard deviation of sensor values for the each axis,
• coefficient of variation of sensor values for the each axis,
• average absolute difference between sensor readings and the mean for the each axis,
• interquartile range sensor value for the each axis,
• an average of a square root of a sum of a square of x, y, z axis values,
• binned distribution for the each axis,
• number of peaks for the each axis normalized by total session time,
• difference between maximum and minimum peak values for the each axis,
• average peak value for the each axis, and
• average time between the peaks for the each axis.

A system comprising:

• a user interface device configured to output a plurality of input profile records (IPRs) associated with a first user, the plurality of input profile records each based on a plurality of user inputs and indicative of identity of the first user;
• and
• a server including
• a memory including an input profile record repository;
• and
• an electronic processor in communication with the memory, the electronic processor configured to
• receive the plurality of IPRs,
• control the memory to store the plurality of IPRs in the input profile record repository,
• receive a current IPR associated with a second user,
• determine whether the second user is the first user by comparing a first one or more biometric features based on the plurality of IPRs and a second one or more biometric features based on the current IPR, and
• responsive to determining that the second user is the first user, output an identity confirmation that the second user is the first user.
