A document liveness detection method comprising using a hardware processor for prompting an end-user of an electronic device, having a camera, to provide an image sequence of a physical document whose orientation is undergoing change; and image-processing the image sequence to yield an output indication of whether or not the image sequence was generated by capturing a live or physical document; and providing the output indication to at least one computerized system or human.

In a general aspect, orientation information is used to generate a unique code. In some aspects, orientation information is extracted from an object. The object includes multiple elements, and the orientation information indicates the relative spatial orientations of the respective elements. The orientation information can be extracted, for instance, by a scanner system that detects the elements. A unique code is generated for the object based on the orientation information. In some examples, the elements are diamond particles that each have one or more color centers, and the orientation information is extracted by detecting the color centers.

A method is disclosed which is performed by at least one first apparatus. In the method, information indicative of at least one characteristic of a franking is obtained. It is determined whether or not the franking is a counterfeit franking and/or a reused franking based on the obtained information or based on the obtained information and based on reference information indicative of at least one characteristic of a franking. The at least one characteristic includes at least one of a physical characteristic of the franking, a visual characteristic of an image provided on the franking, and/or a characteristic based on at least one material of the franking.

A paper sheet processing device includes: an input unit into which paper sheets are input from the outside; an identification unit for identifying the paper sheets fed out from the input unit while allowing them to pass through in a first direction and identifying the paper sheets while allowing them to pass through in a second direction opposite to the first direction; a temporary storage unit for temporarily storing the paper sheets identified as being acceptable by the identification unit; a payout unit for accommodating the paper sheets identified as being unacceptable by the identification unit so as to be able to be taken out to the outside; and a storage unit for storing the paper sheets fed out from the temporary storage unit and identified by the identification unit while being allowed to pass through the identification unit in the second direction, wherein the paper sheets fed out from the temporary storage unit and identified by the identification unit while being allowed to pass through the identification unit in the second direction can be transferred to the input unit.

The present disclosure describes a method and computerized means for creating dynamically evolving moiré shapes on curved surfaces. The method applies geometrical transformations in order to obtain curvilinear moirés and creates the moirés on curved surfaces by applying mappings from planar space to 3D space. The method relies on the superposition of a base layer with base bands and of a revealing layer with sampling elements. The dimensions of the revealing layer sampling elements such as cylindrical or spherical lenses as well as the distances between the base and revealing layer surfaces are adapted to the space between neighbouring isoparametric lines that define the curved surface. The resulting moiré shapes evolve smoothly on the specified curved surface and show recognizable shapes such as words, letters, numbers, flags, logos, graphic motifs, drawings, clip art, and faces.

The present invention is a system and method to equip the ATM (Automated Teller Machine) with the special hardware to detect the each currency note to determine whether that note is a legal tender or not. The counterfeited currency hardware will work with computer executable instructions to detect counterfeited notes while feeding and dispensing in to and from the ATM machine respectively. The aim of the invention is to negligate the chance of counterfeited currency being fed and dispense from the ATM.

The present disclosure relates to signal processing such as image processing, signal encoding, digital watermarking and data hiding. A sparse or dense digital watermark signal can be conveyed with a narrow-band absorption material corresponding to a center wavelength of a Point of Sale (POS) barcode scanner. The POS barcode scanner typically captures 2D imagery. Since the narrow-band absorption material absorbs over a narrow-band it is relatively imperceptible to the Human Visual System (HVS) but can be seen by the POS scanner.
