Abstract

Disclosed is a File Security System using hand-writing signature verification. Hand-writing signature input is required before file manages, i.e., open, copy, or discard, then input signature is collated with registered signature for that file. File manage success only when those signatures are matched.

File Security System by Hand-Writing Signature

      Disclosed is a File Security System using hand-writing
signature verification.  Hand-writing signature input is required
before file manages, i.e., open, copy, or discard, then input
signature is collated with registered signature for that file.  File
manage success only when those signatures are matched.

      In this system, each file can include hand-written signature
datum which was input with a pointing device such as a stylus on pen
based computer.  Only limited people whose signature is registered on
a objective file can access that file.  This brings powerful protect
for files because hand-writing signature is hard to imitate.

      The Figure shows the mechanism of this system.  File owner can
register or delete signature on a file through Signature Management
Program.  File user input hand-writing signature when he tries to
access the file.  Then, Signature Management Program compares input
signature with the registered information using Signature
Verification Program.  If input signature matches one of the
registered signature, required file access is permitted.

      This system can be applied not only on application program, but
alson on operating system.  Careful and strong security can be
realized in case of building in a operating system.
