(LaTeX) Abstract:

Peer-to-peer ({P2P}) networks have received great attention
for sharing and searching information in large user communities.
The open and anonymous nature of {P2P} networks is
one of its main strengths, but it also opens doors to manipulation
of the information and of the quality ratings.
In our previous work (J. X. Parreira, D. Donato, S. Michel
and G. Weikum in {VLDB} 2006) we presented the {JXP} algorithm
for distributed computing {P}age{R}ank scores for information
units (Web pages, sites, peers, social groups, etc.)
within a link- or endorsement-based graph structure. The
algorithm builds on local authority computations and bilateral
peer meetings with exchanges of small data structures
that are relevant for gradually learning about global properties
and eventually converging towards global authority
rankings.
In the current paper we address the important issue of
cheating peers that attempt to distort the global authority
values, by providing manipulated data during the peer
meetings. Our approach to this problem enhances {JXP} with
statistical techniques for detecting suspicious behavior. Our
method, coined {T}rust{JXP}, is again completely decentralized,
and we demonstrate its viability and robustness in experiments
with real {W}eb data.
