A system for managing conditional purchase offers is disclosed where an individual searching for a ticket to a particular event may provide a guaranteed purchase offer to a plurality of potential sellers. Various methods and systems for completing such a transaction are also disclosed. An exemplary method includes: making available a guaranteed purchase offer to a plurality of potential sellers; potential sellers examining offers corresponding to a ticket they possess; and a potential seller providing an acceptance to the guaranteed purchase offer. The disclosure describes a method of payment whereby both the buyer and seller must provide credit card pre-authorization to ensure payment and delivery of the ticket. Also, one embodiment discloses a delivery of the ticket that includes the participation of the venue hosting the event. In this embodiment, the traditional practice of exchanging tickets for cash is replaced with an electronic serial number system. According to this system, the venue may be notified to cancel the serial number originally assigned to the ticket held by the seller, and re-assign a new serial number directly to the buyer. The buyer may then exchange this number for a ticket at the venue box office.

Conditional purchase offer management system for event tickets

A security paper is provided for incorporation in a security document, or other document having intrinsic value. The security paper includes a resinous substrate sheet on which indicia are printed. Paper sheets are laminated on either side of the resinous substrate sheet using a suitable adhesive. In the laminated security paper, the indicia printed on the substrate sheet are undetectable when viewed in reflected light, but become apparent when viewed transmitted light within the visible spectrum. The security paper may be incorporated in a security document in which a set of indicia printed on at least one of the outer faces of the paper sheets, such that the indicia on the substrate and the indicia on the document form a total image when viewed in transmitted light. A method for manufacturing the security paper is also provided.

An alterable ticket and a system and method for controlling access to and within a venue using the alterable ticket. As described in one aspect of the disclosure, a ticket holder purchases such a ticket that conveys a right to access the venue. The ticket is altered in order to modify that right. Because the ticket is altered, it cannot be used by the ticket holder to gain access to the venue. A computer system tracks that the ticket has been altered and enables a refund to be provided to the ticket holder. In this way, a second ticket, conveying the same right as the altered ticket, may be sold to a second ticket holder. According to another aspect of the disclosure, a ticket holder purchases a ticket that conveys a right to occupy a first seat in a venue. The ticket is physically altered in order to upgrade the first seat to a second seat.

Several techniques to acquire a counterfeit proof security document The invention includes improvements for use with non-replicable image line frequency techniques, as well as stand-along printing techniques, that exhibit electro-optical copy and photographic copy frustration characteristics such as experiences with use of color-graduated (tonally graded) substrates, blooming or flaring print patterns, pixel differentiation of discrete indicia and combinations of these with certain printing ink (or) varnish under/overcoat

Anti-photographic/photocopy imaging process and product made by same

A paper substrate is laminated with a metalized layer forming a mirrored surface. A partially transparent black diffraction grating is applied by stochastic screening to the mirrored surface. The diffraction grating forms a frequency modulated pattern from selected geometric shapes. Information, such as alphanumeric indicia or graphics, is printed on the stochastic screen to thus form a reflective diffraction device which is printable in a conventional manner while inhibiting reproduction of the printed information by conventional techniques, including black and white and color photo-reproduction and facsimile machines. The partially transparent black stochastic screen forms a diffraction grating on the metalized layer so that when illuminated from the light source of either a specular or diffuse illumination-type photocopier, random interference patterns of light occur at the interface of the metalized surface and the stochastic screen. The diffracted light is not readable by a photocopier drum with the result that the indicia is not legibly reproduced. Thus, the indicia printed on the security document is protected from counterfeiting and unauthorized copying.

Security printed document to prevent unauthorized copying

A document has information appearing thereon, with at least a portion of the information being located on a front face of a portion of the document The front face portion has a color with a sufficiently low reflection spectral response to render the document portion substantially incapable of being photocopied in an information-readable manner The document portion is capable of transmitting visible light from the rear face to the front face to cause sufficient contrast between the relatively non-translucent information and the transmitted light to enable the information to be read by a human eye viewing the front face of the document when visible light is transmitted through the document from the rear face to the front face

Method of rendering documents resistant to photocopying and anti-copying paper therefor

Confidential information is printed, typed or otherwise applied to paper with a colour having a reflection spectral response or less than about 10% for light with a wave-length below about 600 millimicrons. The colour is sufficiently contrasting with the information to enable the information to be read by the human eye when the document is viewed under white light, but the document cannot be successfully photocopied.
