    摘要: The invention relates to a method for securing a document including a visual element, carried out by a processing unit comprising processing means, the method comprising generation, from the visual element, of a reference security datum, and storage of the reference security datum,wherein the reference security datum is generated by means of an algorithm configured so as to generate: for any image acquired from the visual element, a security datum whereof the differences relative to the reference security datum are less than a determined threshold, and for any image acquired on a different visual element, a security datum whereof the differences relative to the reference security datum are greater than said threshold.

    摘要: According to the embodiment, an image forming apparatus includes an image forming unit, a writing unit, and a processor. The processor forms a first image again on a third sheet, when the writing unit does not succeed in writing information in a wireless tag of a first sheet, on which the first image is formed by the image forming unit. Further, the processor discharges the third sheet prior to a second sheet, on which a second image is formed, the second image being next to the first image.

    摘要: A hybrid currency banknote includes a banknote having visible markings. One or more light-controlling elements and a controller are embedded in or on the banknote. The controller is electrically connected to the one or more light-controlling elements to control the one or more light-controlling elements. A power input connection is electrically connected to the controller, or one or more light-controlling elements, or both. A power source can be connected to the power input connection, for example a piezoelectric or photovoltaic power source. In response to applied power, the controller causes the one or more light-controlling elements to emit light. A value can be stored in a memory in the controller and displayed by the light-controlling elements. The value can be assigned or varied by a hybrid currency teller machine.
