Abstract: A redundantly printed security-enhanced document, printing method and system ensure the meaning of the information imparted by variable indicia printed by redundant printing on the document with removable scratch-off coatings. By printing the variable indicia with multiple colors, redundancy and integrity of the intended indicia is achieved. Additionally, inverted color indicia countermeasures to pinprick attacks are also disclosed. The redundantly printed document, methods and systems enhance the overall appearance of the redundantly printed document, and reduce possible consequences resulting from misprinted variable indicia. The resultant printed process color indicia maintains a grayscale equivalent level of a process color greater than or equal to the measured grayscale equivalent level of the substrate surface plus an additional contrast delta of 15%.

Abstract: A production method and system are provided for enabling the secure sharing of a common prize fund across multiple lottery or contest games and/or sub games. By sharing common inventory control and validation files the multiple games will validate on existing lottery or contest systems without the need for any software or hardware modifications. These methods and systems enhance the games, as well as potentially expand the consumer base for the games.

Abstract: A redundantly printed security-enhanced document, printing method and system are provided for ensuring the meaning of the information imparted by variable indicia printed on documents with removable scratch-off coatings by the redundant printing.

Additionally, inverted color indicia countermeasures to pinprick attacks are also disclosed. The redundantly printed document, methods and systems enhance the overall appearance of the redundantly printed document, and reduce the consequences possibly resulting from misprinted variable indicia.

Abstract: A method and system include digitally imaging a secure portion and a non-secure portion of scratch-off coating protected gaming documents of at least one game, the gaming documents including variable indicia, the gaming documents and the at least one game being associated with at least one overall print run, each print run including (i) a plurality of non-winning gaming documents and (ii) a plurality of winning gaming documents determined by revealing secure variable indicia according to predetermined game programming, and wherein at least the secure portion of digital imaging is hidden under the scratch-off coating. The secure portion can be encrypted into ciphertext with the non-secure portion remaining plaintext or cleartext. This enables digital imaging on demand across a local or distributed network of both secure and non-secure areas of instant lottery tickets or other documents having scratch-off coatings.

Abstract: A printing method or system for making a security-enhanced scratch-off document and the document so made are disclosed. The security-enhanced document includes a substrate, variable indicia, at least one other printed portion having background noise, and a scratch-off-coating layer applied over the variable indicia to maintain the variable indicia unreadable until the scratch-off-coating is removed by being scratched off. The variable indicia includes ink having a signal-to-noise ratio relative to the background ink noise of the document's at least one other printed portion, such that the variable indicia are unreadable with reference to the at least one other printed portion when the scratch-off-coating remains intact. Additionally, digitally imaging countermeasures to unassisted and assisted mechanical SOC lift are also disclosed. These methods and systems enhance the overall appearance of the ticket as well as potentially reduce the time and setup costs between print runs.

Abstract: A computer-implemented method and system are provided for enabling digital imaging of both secure and non-secure areas of instant lottery tickets on demand across a geographically diverse network. Instant lottery tickets produced with this system accommodate smaller volume print runs, process color, and a greater level of customization.

Abstract: A security-enhanced document includes a substrate; at least one lower portion of graphic imaging with or without first variable indicia directly or indirectly digitally imaged on the substrate; at least one release coat applied over the lower portion; at least one SOC applied over the release coat to maintain the lower portion imaging unreadable until removal of the SOC; and at least one overprint upper portion with digital imaging of second variable indicia over the SOC, the overprint upper portion being registered to cover at least a part of the imaging of the lower portion, the overprint upper portion being associated with the lower portion, such that the upper portion has at least one associated feature imaged with respect to a visual or thematic aspect of the lower portion. The document enhances the popularity and fun of games using the document, and may expand the consumer base for the games.

Abstract: A method of encrypting at least a portion of PostScript vector language, where the PostScript vector language includes a cleartext portion and a ciphertext portion, the method including: (a) encrypting at least a part of the PostScript cleartext portion via an encryption algorithm with a generated encryption key resulting in at least a part of the ciphertext portion and overwriting the PostScript cleartext portion with the resulting at least part of the ciphertext portion; (b) saving the encryption key in a file separate from a file containing the PostScript vector language; (c) linking both the encryption key file and the PostScript file in an image processor interpreting the PostScript vector language to display or print PostScript graphics; (d) decrypting the at least part of the ciphertext portion resulting in decrypted PostScript cleartext; and (e) executing the resulting decrypted Postscript cleartext to produce an image on a document or screen.
