A method for implementing banknote counting includes: if counterfeit banknote is detected in the banknote counting process, recording the sequence, the denomination, and the quantity of the counterfeit banknote; extracting the counterfeit banknote and calculating the amount of the counterfeit banknote; determining, according to a user identity information, whether a circulation amount of counterfeit currency and number of times of circulation of counterfeit currency having a mapping relationship to the user identity information exist in a preset counterfeit currency circulation database; if existing, updating the circulation amount of counterfeit currency and changing the number of times of circulation of counterfeit currency; and if the updated circulation amount of counterfeit currency is greater than a preset amount threshold and the updated number of times of circulation of counterfeit currency is greater than a preset number of circulation threshold, sending an investigation instruction to the public security department.

A security document with a first security element, which includes a first item of visually recognizable and in particular machine-readable information, and a second security element, which includes a second item of in particular machine-readable information which can be used to verify the first item of information. A method for the authentication thereof is also described.

A method for verifying a security document by means of a reading device wherein first transmission and/or reflection properties of a first region of the security document are detected in a first spectral range by the reading device and a first data set specifying these properties is generated therefrom, wherein the first region at least in some regions overlaps an optical security element arranged on the security document or embedded in the security document and wherein second transmission and/or reflection properties of the first region of the security document are detected in a second spectral range by the reading device and a second data set specifying these properties is generated therefrom, wherein the first spectral range differs from the second spectral range, and wherein, the authenticity of the security document and/or of the security element is checked on the basis of at least the first data set and the second data set.

A banknote monitoring apparatus includes a reception section that receives information including a serial number from each of a plurality of banknote processing apparatuses processing a banknote with the serial number; and a control section that determines whether a specification of the banknote has been changed based on an identification rate of the serial number obtainable with the information received.

A security document with a first security element, which includes a first item of visually recognizable and in particular machine-readable information, and a second security element, which includes a second item of in particular machine-readable information which can be used to verify the first item of information. A method for the authentication thereof is also described.

Optical elements with anisotropic, patterned surface relief microstructures in which information is encoded in the distribution of the orientation of different zones. From the analysis of the distribution of the light scattered from the element, the orientation distribution in the element and therefore the encoded information can be evaluated. The elements are particularly useful for securing documents and articles against counterfeiting and falsification.

The invention relates to a method for forming and detecting security elements on the surface of a component and/or in a component, in which at least one layer or at least one region that is preferably formed of a magnetic material or of a material different from the component material is formed on the surface of the component and/or in the component that is formed of a magnetic or of a nonmagnetic material in a locally and geometrically defined manner. At least one ablated track, at least one heat-affected region and/or at least one remelted treatment track are/is formed by a locally and geometrically defined ablation of material or input of energy on/at the surface of a component along a predefined contour corresponding to the respective security feature. In the manufacture of the component, a magnetic material different from the material of the component is introduced into the component at at least one predefined position in a locally and geometrically defined manner by way of a generative production process. To detect the security element, a magnetization unit is used to generate at least one magnetic field penetrating into the component or a magnetic flux is produced inside the magnetization unit that penetrates into the component. To check a security element formed in this way, a detection unit is used to detect the magnetic stray fields occurring on the security element as a result of the at least one magnetic field, and the measurement signals captured by the detection unit are transferred to an evaluation unit having an image-processing or pattern-recognition system. Using the evaluation unit having an image-processing or pattern-recognition system, it is checked, by way of the detected magnetic stray fields, whether or not the detected security element corresponds to a specification.

Disclosed is a method for authenticating and/or checking the integrity of a subject, including:—visually superimposing, optically or electronically:—at least one so-called authentication image of at least one authentication region of an authentic subject, the authentication image including at least one texture of random composition,—and, also, the authentication region per se of a candidate subject or at least one verification image of the authentication region of the candidate subject,—in the event of observing, on the image resulting from the superimposition, a Glass pattern optical phenomenon in the authentication region, concluding that the candidate subject is the authentic subject and/or the at least partial integrity of the authentication region of the authentic subject.

The invention relates to a method for authenticating a secure document comprising data printed by analogue or digital printing, said method comprising the following operations:—definition, from among a set of graphical and/or alphanumeric data of the secure document, of at least one distinct data area including at least one distinctive pattern;—during an operation of fabrication of the secure document, reading the distinct data area onto a storage device so as to form a distinct reference data area;—in the course of an operation of verification of the authenticity of the secure document, extracting the distinct data area from a digitized version of the secure document; and—comparing the extracted distinct data area with the distinct reference data area so as to determine a level of matching between said distinct data areas and to deduce therefrom a positive authentication or negative authentication.

A micro-optic device, including: a substrate; a plurality of image elements in an image plane; and a plurality of focusing elements, each focusing element focusing light to a focal point on the image plane and magnifying any portion of an image element falling within the focal point to thereby produce an image pixel projected to a user at one or more viewing angles, the focal point having an extent smaller than the image element, wherein each image element includes an image sub-element having a different discernible level of brightness to elsewhere in the image element, the brightness of each projected image pixel being dependent on the proportion of the focal point filled with the image sub-element, and wherein each image sub-element has one or more attributes in the image plane, such that, from a given viewing angle, the brightness of each projected image pixel is dependent on each attribute of each image sub-element.
