1. A steganographic pattern detection electronic validation machine, the steganographic pattern detection electronic validation machine comprising:
a housing;
a camera supported by the housing in a position to capture a digital image of a ticket with a steganographic pattern printed in a background area of the ticket;
a digital processor supported by the housing; and
a memory device supported by the housing and storing a plurality of instructions, which when executed by the digital processor, cause the digital processor to:
orient the captured digital image to an X/Y grid,
find edges of the ticket in the captured digital image,
align the edges of the ticket in the captured digital image to the X/Y grid,
analyze the captured digital image for no apparent pattern,
create a modified digital image to reveal the steganographic pattern by analyzing the captured digital image for any apparent patterns printed in the background area of the ticket, and
verify that the captured digital image did not include an apparent pattern and that the modified digital image did include an apparent pattern, thereby validating authenticity of the ticket.
