The company receives an U.S. patent to secure it with DNA blockchain technology. The U.S. Patent and Trademark Office has granted Nokia Technologies (NYSE: NOK) Patent No. 11,196,573 for the “Secure Decentralized Domain Name System”.

In addition to Nokia, several companies have applied for patents related to blockchains for domain names. This is quite broad and seems to circumvent the traditional “replace traditional DNA to blockchain” mentality.

The patent states:

Some alternative decentralized domain name system (DNS) solutions based on blockchain technology have been proposed. Such blockchain-based solutions may be more immune to Man-in-the-Middle (MITM) attacks. However, such systems still have a number of limitations. First, they are not fully compatible with the current Internet infrastructure for Domain Name System (DNS) and security services, so they require additional browser software, such as plug-ins or even independent browsers. Second, they need a local copy of the blockchain. Third, only a few new top-level domains are supported.

The authors of the patent believe that the big problem with our current DNS and our use of the web is that certificate providers can be hacked or forced to act as a single point of failure in the web’s chain of trust.

The solution proposed by Nokia records domain registrations in the blockchain to add a layer of trust. The patent also explains how this can be applied to the Internet of Things and how a household can use a private blockchain for greater security.
