IBM Registers Patent To Protect Blockchain From Hackers

IBM Publishes Another Blockchain-Related Patent

The United States Patent and Trademark Office on the official website published a patent for developing an application to improve safeness of blockchain networks filed by a technology giant IBM in October 2016.


The document describes security methods for permissioned and private blockchain systems to resist attacks while maintaining user permissions and privacy. Replay attacks occur when fraudsters repeat transactions in blockchain with the help of deception of network validators.


The IBM patent involves verifying transactions on a computer system network by generating a unique value that can be used only once and is signed with a digital security certificate. The document describes transaction security options for a number of main network systems.


A study published in the fall of 2018 revealed that IBM already has 89 registered blockchain patents that make it the second largest company in the world in terms of similar patents after the Chinese giant Alibaba (90 applications).


Last week, IBM filed two patent applications: one aimed at supporting network security, and the second suggests using blockchains to improve database management systems.


Earlier, the ex-chairman of the board of directors of IBM stated that he still does not see a way to bring public blockchains in line with the General Data Protection Regulations (GDPR).
