The current document is directed to distributed-secure-storage systems, and processes carried out within the distributed-secure-storage systems, that provide for secure storage and retrieval of confidential and critical data, referred to as “secrets,” within distributed computer systems. The secret-storage systems partition an input secret into multiple secret shares and distribute the secret shares among multiple secret-share-storing node subsystems, without persistently storing the secret itself. An agent within a client device subsequently requests a secret share corresponding to a secret, or a share of data derived from the secret share, from each of the multiple secret-share-storing nodes. The multiple secret-share-storing nodes additionally cooperate to periodically alter the stored secret shares corresponding to a secret in a way that allows agents to recover the original secret, or derived data, from all or a portion of the altered secret shares or derived-data shares.

If it is not possible, then the method selects, conditional on sensing proximity to the designated delivery address with reference to the computing device's current location, from among one or more possible delivery addresses which have been pre-registered by the recipient as local addresses of friends an alternative delivery address at which a friend is currently located with reference to a mobile device registered to that friend. If a suitable friend who is at home is found, then the packet is delivered to the friend. The delivery is then confirmed, notifying the recipient of delivery of the packet to the alternative delivery address.
