Cisco, a worldwide leader in IT and networking, is developing a method of confidential group communications based on Blockchain technology, according to a patent application released by the US Patent and Trademark Office (USPTO) March 29.
In the application, the company describes the way Blockchain can ensure more confidential and secure group messaging, file sharing, and tracking of membership history. The technology in the patent intends to address common challenges faced by ad hoc messaging groups:
“How group membership is established, communicated, updated, and secured from unauthorized tampering are common problems for which a construct is not available that can be effective in the context of dynamic, decentralized, and self-organizing group.”
“This method permits ad hoc and decentralized group definition, dynamic and decentralized membership updates, open sharing, tamper resistance, and tracking of membership history.”
The method suggests establishing a secured network by using cryptographic keys. Only authorized participants will be allowed to join a group chat based on the aforementioned decentralized network.
