Abstract

Generating a private key recovery seed based on random words extracted from an input memory of a user and using the recovery seed to recover the private key. An input that is related to a specific memory of a user is received. The specific memory was previously entered and used to generate random words that are related to each other by being included in the specific memory. The random words are extracted from the received input. The random words are associated with a first private key recovery mechanism for recovering a private key. The random words are input into the first private key recovery mechanism to generate a recovery seed. The recovery seed is input into a second private key recovery mechanism. The second private key recovery mechanism generates a recovered private key upon performing a recovery operation on the private key recovery seed.
