Blockchain Document Tracking
The patent was applied for by Xerox to the United States Patent Office back in August this year. According to the details of the patent application, the blockchain system would create a tracking that would keep in check any changes or updates made in any kind of a document or a digital file. The data would be viewable by any allowed third party so they can know exactly what changes are made over the life of the document.
The immutable nature of blockchain means that any changes made by authorized people would become a permanent part of the document, making it extremely resistant to tampering. The high security of the decentralized technology also ensures that only authorized persons are allowed to make changes in the files.
The documentation company explained in its patent filing that the system would consist of a collection of nodes that would approve or disapprove changes. In case of a disapproval users will be alerted to the disagreement.
Xerox says that its patent has extensive applications in the field of electronic record. Digital files are very prone to tampering. This can have very serious implications in case of medical or financial records, tampering of educational and job related documents of applicants and even criminal related ones.
The blockchain system would mean that every change ever made on the document would be traceable and verified through nodes. The changes would be substantiated and no more need of third party or self verification would result in cost substantial reduction.
Xerox has already made previous patent applications for a blockchain technology related to documentation. It made one in 2016 in that had time stamping on the blockchain, enabling record keeping of the document and making it un-editable for its live on the system.
