The present invention provides a method and apparatus for the production and labeling of objects in a manner suitable for the prevention and detection of counterfeiting. Thus, the system incorporates a variety of features that make unauthorized reproduction difficult. In addition, the present invention provides a system and method for providing a dynamically reconfigurable watermark, and the use of the watermark to encode a stochastically variable property of the carrier medium for self-authentication purposes.

A method of introducing a verification check to a product is provided. The method comprises generating an alphanumeric code associated with the product, using one or more digits in the code to calculate a resultant value and modifying at least one digit in the code based on the resultant value. The resultant value determines the form of modification based on a predetermined selection of possible modifications.

The invention relates to a method for checking the authenticity of the specifications of origin of products and the specifications of time-based guarantees of product properties. The method is used to combat product piracy and to provide the prerequisites for automated identification of products, the shelf-life of which is just before the predefined expiry thereof or the expiry of the time based functional guarantee thereof. The field of application extends in this case to checking food, pharmaceutical products through to technical products.

A method for processing banknote includes: conveying, by a conveyor, the banknote taken in from an intake port; discriminating, by a discrimination sensor, whether the banknote conveyed by the conveyor is first banknote or second banknote, the first banknote being to be stored in at least one storage, the second banknote being to be forcibly stored in the at least one storage; and performing, by a controller, output processing to output forcible storage information used in forcible storage of the second banknote, the forcible storage information being output without user intervention.

In a method for identifying desynchronization between representations of data obtained from an ordered plurality of documents, a processor can receive ordered first and second pluralities of data strings obtained from the respective plurality of documents; compare each data string in the first plurality to the corresponding data string in the second plurality and to each data string sequentially before or sequentially after the corresponding data string in the second plurality; based on the comparison, designate each data string in the first plurality as being one of synchronized, leading, or trailing; identify a continuous sequence of N data strings in the first plurality that all have a designation of leading or all have a designation of trailing, where N equals or exceeds a specified sequence threshold; and generate a single error signal that identifies all N of the data strings in the continuous sequence as being desynchronized.

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.
