Bank Of America Adds Private Key Storage Filing to Stockpile of Blockchain Patents

Bank of America has gained a further cryptocurrency-related patent, a filing confirmed Oct. 30, continuing its efforts to "Be prepared" for the industry's future growth.

The latest award, which adds to the bank's mounting stack of cryptocurrency and blockchain patents, references storage methods for private keys.

Specifically, the filing reads, current opportunities for ensuring private keys remain untampered with are insufficient.

"[W]hile many [] devices may provide for acquiring evidence of a security breach, such devices do not provide for real-time response to such breaches, such that misappropriation of private cryptography keys is prevented," BoA writes.

"Therefore, a need exists for a secure means for storing private cryptography keys. The desired storage means should reduce the risk of misappropriation of keys due to the keys being stored internally within a computing node that is frequently or, in some instances, continuously accessible via a public communication network, such as the Internet."

As Cointelegraph has reported, the banking giant has sought several patents in the past few months, these relating variously to external validation, data storage and others.

At the same time, officials have remained highly skeptical of cryptocurrency itself, banning credit card customers from purchasing it while admitting Bitcoin represented a "Troubling" issue for its operations.

In June, CTO Catherine Bessant said that the patent routine should safeguard the bank's interests in the event of the technology surrounding cryptocurrency becoming mainstream.

"We've got under 50 patents in the blockchain/distributed ledger space," Fortune quoted her as saying at the time.

"While we've not found large-scale opportunities, we want to be ahead of it we want to be prepared."
