Xerox has won a patent for a technology that will allow the creation of digital evidence for documents and other types of data using the blockchain.
The corresponding document was published on November 13 on the website of the United States Patent and Trademark Office (USPTO).
In the description of the patent, the method of using the blockchain technology for data binding (authorship of images or videos) to a specific period of time is presented. Both open and private versions of the blockchain can be used.
According to the authors of the patent, the technology can be used to audit generated files in such areas as finance and medicine, tax reporting and education. Scope of criminal investigations is also mentioned, including the records of interrogations of suspects, photographs from crime scenes, and the results of DNA tests, the protection of which from possible falsification is of great importance.
The application was filed in August 2017 and had a common name with another Xerox patent application of 2015 and did not contain any mention of the blockchain.
