Abstract
Techniques are provided for user behavior analytics using keystroke analysis of pseudo-random data strings. One method comprises obtaining timestamps corresponding to keystroke activities on a device of a user associated with typing a pseudo-random character string comprising multiple characters, wherein at least one timestamp is adjusted based on errors associated with the typing of the pseudo-random character string; determining a time difference between keystroke activities associated with the pseudo-random character string using at least one adjusted timestamp; obtaining a time difference distribution for a subset of character sequences in the pseudo-random character string; determining a probability value for one or more character sequences in the subset; and determining an aggregate probability value for the pseudo-random character string based on the probability values. An authentication and/or an identity verification of the user can be based on the aggregate probability value for the pseudo-random character string.
