TL;DR: In this paper, a banknote or other security document is altered to effect the encoding of plural-bit digital data (i.e., the banknote is digitally watermarked).
Abstract: Line art on a banknote or other security document is slightly changed to effect the encoding of plural-bit digital data (i.e. the banknote is digitally watermarked). When such a banknote is thereafter scanned, the resulting image data can be recognized as corresponding to a banknote by detection of the encoded data. (Alternatively, the image data can be recognized as corresponding to a banknote by machine detection of other forms of watermarking, or by reference to visible structures characteristic of banknotes.) In response to detection of a banknote, the detecting apparatus (e.g., a scanner, photocopier, or printer) can intervene so as to prevent or deter counterfeiting. For example, the apparatus can interrupt a copying operation, and display a message reminding the operator that it is illegal to reproduce currency. Another option is to dial a remote service and report the attempted reproduction of a banknote. Yet another option is to permit the copying, but to insert forensic tracer data (e.g. steganographically encoded binary data) in the resultant copy. The tracer data can memorialize the serial number of the machine that made the copy and/or the date and time the copy was made. To address privacy concerns, such tracer data is not normally inserted in photocopied output, but is so inserted only when the subject being photocopied is detected as being a banknote.
TL;DR: In this paper, a banknote detector device for an automatic teller machine, for differentiating between non-accepted and accepted banknotes, is presented, which includes an alignment, banknote face classification unit, a printed pattern positioning unit and a comparison unit where, for at least one face of the banknote, the BI and RBI, being in exact pattern position in relation to each other, are compared pixel per pixel according to a predefined comparison procedure.
Abstract: A banknote detector device for an automatic teller machine, for differentiating between non-accepted and accepted banknotes, includes a banknote image sensor to receive and scan at least one face of an input banknote and to store a banknote image (BI) of each scanned. The image includes image data in the form of a number of pixels; and a reference banknote image (RBI) storage where one reference banknote image, being processed from a predetermined number of banknote images from accepted banknotes, is stored for each face of each banknote. The device includes an alignment, a banknote face classification unit, a printed pattern positioning unit and a comparison unit where, for at least one face of the banknote, the BI and RBI, being in exact pattern position in relation to each other, are compared pixel per pixel according to a predefined comparison procedure to classify the banknote as accepted or non-accepted.
TL;DR: The world's first banknote printed on clear plastic film and using optically variable devices (OVDs) was issued in Australia in 1988 after twenty years of research and development.
Abstract: The world's first banknote printed on clear plastic film and using optically variable devices (OVDs) was issued in Australia in 1988 after twenty years of research and development. In the course of this, a great deal of technical as well as logistic issues had to be solved.
TL;DR: In this paper, an automatic teller machine has an input hopper into which checks and banknotes for deposit can be put, and an imaging and sorting device separates the banknotes and checks from each other.
Abstract: An automatic teller machine has an input hopper (20) into which checks and banknotes for deposit can be put. An imaging and sorting device (22) separates the banknotes and checks from each other. The banknotes are fed to a temporary banknote storage device (24) and the checks are fed to a temporary check storage device (26). A receipt for the number of items of each kind deposited is issued to the depositor. A further imaging device (28) may be provided for subsequent more detailed examination and further sorting of the deposited items. The subsequent examination preferably takes place when the machine is not being used by a customer.
TL;DR: In this article, the authors explore the relationship between national iconography, banal nationalism and conceptions of the state and reveal that non-state actors and institutions are frequently responsible for this key mechanism of official iconographic representation.
