Abstract
Systems, methods, and machines for automatically verifying the authenticity and integrity of a ticket such as an instant lottery ticket, a draw lottery ticket, a passive lottery ticket, and/or a Ticket In Ticket Out (Tito) ticket. The systems, methods, and machines verify the authenticity and integrity of a ticket by capturing a first image of the ticket, verifying that the first captured image does not show an apparent steganographic pattern, processing the first captured image to produce a second image, and then verifying that the second image does show an apparent steganographic pattern.
Claims20
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.
A steganographic pattern detection electronic validation machine for verifying the authenticity of a document having a steganographic pattern printed in a background area, the steganographic pattern detection electronic validation machine comprising:
- a housing;
- a digital camera supported by the housing in a position to capture a digital image of the document;
- a digital processor;
- and
- a memory device storing a plurality of instructions, which when executed by the digital processor, cause the digital processor to:
- generate a modified image of the document comprising an X/Y grid,
- use the modified image to verify that the pattern is not readily apparent,
- create a digital photocopy of the modified image,
- save a resultant digital image, and
- determine one of:
- an absence of a pattern in the captured digital image of the document, and
- an appearance of the pattern in the modified image of the document to verify authenticity of the document.
