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 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. 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 the consequences possibly resulting from misprinted variable indicia.
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 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.
