3 results about "Digital copy" patented technology

A system and a method for verifying authenticity of a physical copy and a digital copy of a document are disclosed. The method comprises registering a document in a repository by storing details related to the document in a location of the repository. A symbology for the document is generated. The symbology is an identifier of the location of the repository comprising the document. The symbology is associated with either a physical or a digital copy of the document. The digital copy of the document is printed to generate a printed copy. The printed copy or the physical copy of the document is scanned to generate a scanned image. The document and the details related to the document present at the location of the repository are accessed. The scanned image is compared with the document stored in the repository to determine the authenticity of either the physical copy or the digital copy of the document.

Arrangements are provided for generating tamper-proof quantum-resistant data structures for storing digital communications transmitted over pubic electronic mediums, such as the Internet. The digital communication may include audio and video data. The tamper-proof quantum-resistant data structures may be stored in a repository used for verifying whether digital copies, such as video clips, are authentic copies or whether they have been altered, such as by artificial intelligence, to include misinformation or disinformation.

The invention relates to a method (100) for automatically detecting digital forgery for the purpose of verifying the conformity of a digital copy (DD) of an official document (OD). Such a method (100) primarily comprises a step (130) of processing one or more images (DF1, …, DFj, …DFm) extracted from the digital copy (DD) in order to produce one or more images (DF1', …, DFj', …DFm') expressing a residual noise, and a step (140) of analysing this residual noise in order to produce a conformity result (SCj, ASC) in relation to the digital copy (DD). Such a method (100) is designed to be implemented by the processing unit of an electronic entity (20) for verifying such conformity, possibly in response to a request from a third-party electronic entity (40) operated by a state or service provider.
