Abstract
A blockchain of transactions may be referenced for various purposes and may be later accessed by interested parties for ledger verification or information retrieval. One example method of operation may include one or more of receiving an access request from a requesting device for access to an encryption key associated with a user device, broadcasting the request to peer nodes for approval or disapproval, storing a transaction to a blockchain indicating the approval or disapproval of the request for access to the encryption key, and providing access to the encryption key when the approval is indicated.
