A method of verifying identity which includes recording coordinates of a reference signature having two dimensional space coordinates x and y and time, t, and pressure (or force), z, exerted by a writer's writing instrument or finger on a recording medium. The method involves measuring and recording an indicium which identifies a portion of the reference signature having a selected characteristic. The coordinates of this portion of the reference signature and the indicium are placed on a portable, readable substrate. The coordinates of an unknown signature which include two dimensional space coordinates x and y and time, t, and force, z, exerted by a writer's writing instrument or finger on a recording medium are recorded. The indicium and the portion of the reference signal are read and stored in memory. The indicium is used to locate a corresponding portion of the unknown signature. The corresponding portion of the unknown signature is compared to the portion of the reference signal to determine if the two match within a predetermined threshold criterion.
