COLLUSION DEFENDER PRESERVING SUBSCRIBERS PRIVACY IN PUBLISH AND SUBSCRIBE SYSTEMS

Abstract

In order to disperse information
from distributors to supporters in a roughly
linked manner through an organization of
dedicated intermediates, the Publish and
Subscribe (bar/sub) structure has been
developed. However, in the event that retailers
are hacked or penetrated, sensitive information
may be exposed to malicious elements; or, even
worse, if retailers are curious about the
information, it may be exposed to dealers
themselves. Encrypting data before sending it
out to reps is a practical step toward protecting
sensitive distributions and memberships. The
state-of-the-art methods allow agents to do
encoded matching without revealing
memberships and distributions. However,
nefarious vendors may learn about the interests
of honest backers, even if the interests are
jumbled, if they collude with noxious endorsers
or distributors. In this piece, we describe a
bar/sub structure that can keep memberships
and distributions hidden even from
intermediates that can't be trusted.
Additionally, we argue against dealer-endorser
attacks in which one party is dishonest (or
distributers). At At last, we have implemented a
prototype of our solution to demonstrate its
viability and effectiveness.
