The Bank of America (BofA) has filed a new patent for embracing multiple digital signatures in a distributed network.

This is according to a United States Patent and Trademark Office (USPTO) filing.

The fresh patent proposed a system for handling data communication from Internet-linked devices. The document emphasized that “the invention provides automated determination of which devices are communicating to which third-party entities and, in some embodiments, the type of data being communicated to such third-party entities.”

BofA’s planned system tackles devices within an Internet of Things (IoT) realm, describing how each of the Internet-linked devices would communicate data with each other “on an ongoing basis,” while the system lets a user to “select to prohibit (i.e., block) or limit which data is communicated to which third-party entities.”

Also in September, IBM was given a patent for autonomous self-servicing devices within a blockchain-based IoT system. And just last month, LG CNS, a subsidiary of South Korean multinational conglomerate LG Corporation, bared a plan to bolster its enterprise offering of seven platforms including blockchain and IoT to endorse the “fourth industrial revolution.”

Bank of America, said to be one of the largest holders of blockchain-related patents, had continued its own blockchain assessment last month when it filed a patent for documenting and storing cryptocurrency-related transactions in a blockchain-based system.
