摘要:
A method and apparatus for determining a digital signature from an article. A coherent light source directs a beam to illuminate the article and a detector arrangement collects data points from light scattered from many different parts of the article to collect a large number of independent data points, typically 500 or more. By collecting a large number of independent signal contributions specific to many different parts of the article, a digital signature can be computed that is unique to the area of the article that has been scanned. This measurement can be repeated whenever required to test authenticity of the article. Using this method, it has been discovered that it is essentially pointless to go to the effort and expense of making specially prepared tokens, since unique characteristics are measurable a in a straightforward manner from a wide variety of every day articles.

An automated banking machine (10) identifies and stores documents such as currency bills deposited by a user. The machine then selectively recovers documents from storage and dispenses them to other users. The machine includes a central transport (70) wherein documents deposited in a stack are unstacked, oriented, and identified. Such documents are then routed to storage areas in recycling canisters (92, 94, 96, 98). When a user subsequently requests a dispense, documents stored in the storage areas are selectively picked therefrom and delivered to the user through an input/output area (50) of the machine. The control system (30) for the machine includes a terminal processor (548). Identification devices identify the type and character of a document, and distinguish genuine documents, such as genuine currency bills, from unidentifiable or suspect documents.

A bill recognizing and counting apparatus includes a feeding and transporting mechanism; a line sensor to scan an image of the bills; a denomination determination table in which denomination recognition data is registered for at least one currency; a denomination recognizing unit that recognizes a denomination of the currency by referring to the table; a processing-mode switching unit that switches between a denomination mode and a different currency recognition mode; a different-currency recognizing unit that compares a difference in size between a first bill and each bill of a second bill and thereafter with an allowable range, and recognizes whether the each bill of the second bill and thereafter is of the same denomination as the first bill; and a control unit that guides the bill being determined as a different denomination to a rejecting unit or stops the feeding and transporting mechanism.

The application discloses identification and security documents and methods and systems for authenticating such identification and security documents. In one implementation, a document includes a first surface; and a second surface. The first surface comprises a first set of print structures and a second set of print structures. The first set of print structures and the second set of print structures cooperate to obscure the location on the first surface of the second set of print structures. The second set of print structures is arranged on the first surface so as to provide a reflection pattern. In one example, the reflection pattern includes a diffraction grating. The second set of print structures is preferably provided on the first surface with metallic ink. In other implementations a financial instrument or identification document is provided with an organic light emitting diode (OLED) array. The OLED array displays information thereon. The information is preferably correlated to the information on or in the financial instrument or identification document.

A method and apparatus for determining a digital signature from an article made of paper, cardboard, plastic or many other material types. A coherent light source directs a beam to illuminate the article and a detector arrangement collects data points from light scattered from many different parts of the article to collect a large number of independent data points, typically 500 or more. By collecting a large number of independent signal contributions specific to many different parts of the article, a digital signature can be computed that is unique to the area of the article that has been scanned.

Using this method, it has been discovered that it is essentially pointless to go to the effort and expense of making specially prepared tokens, since unique characteristics are measurable a in a straightforward manner from a wide variety of every day articles.
摘要:
Techniques for generating fingerprints for articles and using the fingerprints for various applications. Scan-related parameter values, including the area of an article scanned, may be specified and varied from one scan to another for collecting data points used for generating fingerprints for articles. A paper shredder is provided that is configured to, prior to shredding a paper sheet, scan the paper sheet and generate a fingerprint for the paper sheet. Fingerprints may also be generated for media keys that are used to access media data. The fingerprint generated for a media key may be used to authenticate the media key. Access to media data corresponding to the media key may be made contingent on successful authentication of the media key.
摘要:
Optical identification and/or authentication of a document or item with the help of a marking comprising a random distribution of circular polarized light reflecting particles, the marking being applied to the document or item through an ink, and the reading device exploiting circular polarization to discriminate the flakes from the background.

A method and apparatus for creating and detecting an optically encoded document having a uniquely designed document verification indicator is disclosed. One embodiment includes applying a spatially varying Brewster angle pattern on a substrate. Another embodiment includes an apparatus for detecting the spatially varying Brewster angle pattern including a light source, a slit aperture, a polarizer, at least one parabolic mirror, and an image capturing device.

The document identification method comprises: a step of generating an image, a step of marking a plurality of documents to form said image on each said document with unique variations on each document, the majority of the images formed on said documents presenting a physical anti-copy characteristic satisfying a pre-defined criterion such that said characteristic of the majority of the copies that can be produced based on these images do not satisfy said pre-defined criterion, a step of characterizing said variations to form a unique imprint of the mark formed, for each said document and a step of memorizing said unique imprint. In embodiments, said image only comprises two colors.In embodiments, during the step of characterizing variations, frequency analysis is utilized.In embodiments, during the step of memorizing, the imprint is stored in a database and/or the document is marked with a mark representing the imprint affixed individually on the document.
摘要:
The present invention relates to a bill discriminating and counting apparatus having a function in which two operators can commonly operate the one apparatus. That is, two pairs of a process instruction button for instructing start/stop of a discriminating and counting process and an approval button for approving counting result are provided, two independent storage areas are provided in a storage area in which the counting result is stored, the counting result is stored in the corresponding storage area while each storage area is associated with the pair of the process instruction button and the approval button, and two operators can commonly use the one bill discriminating and counting apparatus by providing occupation switching means for switching an occupation state of the bill discriminating and counting apparatus and occupation state display means for displaying a current-occupation state.
