A method for deterring information copying, includes: combining a watermark serial number incorporate in a given medium with a content serial number to create a combined serial number, the watermark serial number uniquely identifies the given medium, and the content serial number uniquely identifies a content stored on the given medium; creating a digital signature by encoding the combined serial number using a private key of a public/private key pair; imprinting the content serial number and the digital signature on the given medium; decoding the digital signature imprinted on the given medium using a public key of the public/private key pair to obtain the combined serial number; comparing the decoded combined serial number with the watermark serial number and the content serial number imprinted of the given medium; and in response to determining that both match the combined serial number, determining that the content is authentic.

A storage stores money. An outlet can receive money delivered from the storage therein. The outlet is configured to allow the money to be removed from the inside of the outlet. A detector detects a removal action associated with removal of money from the outlet. The controller switches a process on money remaining in the outlet based on a detection result of the detector.

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.

A process for self-recovering from document processing disturbances in a flexible document receiving and dispensing device comprising one or more flexible document storing and dispensing modules, wherein each one of said one or more flexible document storing and dispensing modules is configured to store a respective group of flexible documents, wherein each flexible document is individually identified by a univocal code associated thereto, wherein the process comprises the following steps: A. during a storing operation, one or more flexible documents are stored according to the following substeps: A.1 recognizing the group of flexible documents and reading the univocal code from each one of said one or more flexible documents; and A.2 for each group of flexible documents, storing the univocal codes read at step A.1 in a memory unit of the respective flexible document storing and dispensing module, whereby such univocal codes are stored in a code storage sequence univocally associated to an expected code dispensing sequence including one or more expected univocal codes: B. during a dispensing operation, for each one of one or more flexible documents to be dispensed, performing the following substeps: B.1 reading the univocal code from the flexible document to be dispensed, B.2 comparing the univocal code read at step B.1 with the expected univocal code in the expected code dispensing sequence: B.3 when the compared codes are different, discarding flexible documents from the respective flexible document storing and dispensing module until it is recognized that a subsequence of discarded flexible documents is identical to a subsequence of expected univocal codes, otherwise B.4 dispensing the flexible document.

Embodiments relate to a non-fungible physical (NFP) item. The non-fungible physical (NFP) item comprises an identifier. The identifier is embedded and layered within the non-fungible physical item in an unplanned pattern. The identifier in the unplanned pattern is configured to provide high security against counterfeiting of the non-fungible physical (NFP) item. The identifier comprises at least one of a random marker and a unique marker. The unplanned pattern comprises at least one of a random pattern and a unique pattern. Further the non-fungible physical (NFP) item is registered as a non-fungible token on a blockchain. The NFP item is then paired with the non-fungible token for enabling two-way mutual authentication and enhanced authenticity. The pairing of the NFP item with the non-fungible token enables tracking condition, provenance, and grading of the NFP item.

A method for making an object secure comprises creating a multi-layer graphic signature by superposing, in partial or total transparency, a first random graphic element on a first layer to a second graphic element on a second layer, and storing the graphic signature on or in the object. The method is essentially characterized in that the relative position of the first graphic element and of the second graphic element is random.
