An automated method for authorizing and controlling the production of
optically encoded images is provided. The method comprises receiving from
a user data processor a request for authorization to produce an encoded
image. The authorization request includes user-supplied data comprising
at least one authentication image file. The method further comprises
determining whether the user is authorized to produce an encoded image
using the user-supplied data. Responsive to a determination that the user
is authorized to produce an encoded image using the user-supplied data,
an authentication image signature is generated from the at least one
authentication image file using an image signature algorithm and a
positive authorization response is returned to the user data processor.
The positive authorization response includes the authentication image
signature.
