      POWAY,  Calif.  Sept 21, 2004 - Mitek  Systems,  Inc.  (OTC BB:  MITK),  a
leading developer of image-based fraud protection and recognition  technologies,
today  announced the  appointment of William P. Tudor to the Company's  Board of
Directors.

      Tudor  replaces John Rebelo,  who is retiring from the board due to health
reasons.  Mr.  Tudor has  assumed  the  position  of  director  effective  as of
September  15, 2004. He will also serve on the Board's  Compensation  Committee.
With  more  than 40  years  of  experience  in  computer  programming  and  data
processing,  as well as  significant  knowledge  in systems  analysis,  Tudor is
considered an expert within the systems and process reforms discipline.

strong leadership abilities make him a valuable addition to Mitek's board," said
John M. Thornton,  chairman and CFO of Mitek. "We look for several attributes in
board  appointees,  not the least of which are  industry  experience,  visionary
direction  and  a  passion  for  ethical  and  fiduciary  responsibility.  In an
increasingly  aggressive  marketplace,  we  understand  the  needs of  financial
institutions,  and we are  committed to providing an advanced  fraud  protection
solution that will not only enable banks to further  leverage Check 21, but will
also provide the  necessary  protection  and security for the  institutions  and
their  customers.  As chairman and CFO of Mitek,  I am honored to have Bill join
our organization."

      Currently,  Tudor is a vice president of Scantron  Corporation,  a leading
provider of software  services and systems for the  collection,  management  and
interpretation  of data to the  educational,  financial and commercial  markets.
Prior to this  position,  Tudor  founded  EdVISION,  a  provider  of  curriculum
development  and  assessment  tools for the  education  industry.  EdVISION  was
created in response to the needs of parents and school  systems for a systematic
approach to assess students' performance at each grade level.
