Abstract: An application program spans a plurality of digital social networks. The application program includes an inferred digital social network. Consent is obtained from a plurality of users of the digital social networks to participation in the inferred digital social network. Information is automatically obtained from the digital social networks for the users, through a plurality of respective communication channels, which can be application program interfaces or covert or subliminal channels. The information includes link information between each of the users and other individuals in the digital social networks. The information is aggregated for the users to form the inferred digital social network, corresponding to a graph having nodes representing the users and the other individuals and having links between the nodes representing social relationships.

Abstract: In a digital social relationship network, a social network server computer stores a digital social network representation corresponding to a graph having nodes representing individuals or groups and links representing actual social relationships between the individuals or groups. The server computer obtains relationship-dependent information corresponding to a plurality of links of the graph, and embeds the relationship-dependent information in the digital social network representation stored in the social network server computer. The server computer interactively presents to a user of a client computer connected to the social network server computer a social network of the individuals or groups and the social relationships between the individuals or groups.
