Abstract

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.

Description

Background technique [0001] Banknotes are printed using specially designed measures to prevent counterfeiting. The special paper used has a watermark as well as an embedded security thread containing the printed information. The information printed on the currency is carefully selected and often also has a miniature pattern that cannot be easily seen by the naked eye to make reproduction more difficult. In addition to these hard work, the government is still battling a large number of counterfeit banknotes. [0002] Currently, governments try to prevent counterfeiting by limiting the technology needed to obtain counterfeit currency. However, experienced organizations have the financial means and ability to purchase the latest counterfeiting technology, which includes access to the same paper and the same printing presses that governments use to create banknotes. As a result, the difference between counterfeit and real money isn't even possible for banks to tell the differen...
