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.

A computer readable storage medium storing a program of instructions executable by a machine to perform a method of backing up digital data, the method 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;
- 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;
- and
- 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.
A system of backing up digital data, comprising:
- a processor operable to detect a backup event trigger to backup digital data representing digital cash of a user,
- the processor further operable to retrieve online social network profile of the user,
- the processor further operable to determine 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,
- the processor further operable to determine a number of parts and a threshold based on the parameters and store the number of parts and the threshold in memory;
- the processor further operable to select a list of friends from the social network friends to store the number of parts,
- the processor further operable to transmit a part of the digital data divided into the number of parts to a respective friend's device for storing in the respective friend's device, each of the parts stored with a different friend in the list of friends.
