1. A method of backing up digital data, comprising:
- detecting a backup event trigger to backup digital data representing digital cash of a user;
retrieving online social network profile of the user;
determining parameters associated with the digital data, the user, and social network friends of the user, the parameters associated with the user and the social network friends of the user determined at least from the online social network profile of the user;
determining a number of parts and a threshold based on the parameters, wherein the threshold is defined to be less than or equal to the number of parts, the threshold representing a minimum number of parts required to restore the digital data, wherein the parameters comprise at least an expiration date associated with the digital cash, and wherein the threshold is set to be smaller for an expiration date that is approaching than an expiration date that is farther away;
dividing the digital data using one or more of secret sharing and splitting method into the number of parts;
selecting a list of friends from the social network friends to store the number of parts;
storing a part of the digital data divided into the number of parts in a respective friend'"'"'s device, each of the parts stored with a different friend in the list of friends;
requesting from the friend the part of the digital data and retrieving from the memory associated with the friend the part of the digital, to retrieve at least the threshold number of parts from the threshold number of friends; and
reconstructing the digital data using the one or more of secret sharing and splitting method, based on the threshold number of parts of the digital data retrieved from the threshold number of friends.

Abstract
Backup and restore of digital data may utilize online social network parameters of a user to determine a number of parts into which to divide digital data and distribute the parts. A list of friends from the social network friends may be selected, e.g., based on a relationship to the user in the social network, to store the parts. The parts may be stored in a friend'"'"'s device memory, each of the parts stored with a different friend. The digital data may be reconstructed by obtaining a threshold number of parts from the friends.
