Regularity Based Decentralized Social Networks

摘要

Centralized online social networks (OSNs) have drawbacks, chief among which are the risks posed to the security and privacy of the information maintained by them; and the loss of control over the information contributed by their members. The attempts to create decentralized OSNs (DOSNs) enable each member of an OSN keeps its own data under its control, instead of surrendering it to a central place; providing its own access-control policy. However, they are unable to subject the membership of a DOSN, and the interaction between its members, to any global policy. We adopt the decentralization, complementing it with a means for scalably specifying and enforcing regularities over the membership of a community, and over the interaction between its members.
