RepuScore: Collaborative Reputation Management Framework for Email Infrastructure
Gautam Singaraju and Brent ByungHoon Kang, University of North Carolina at Charlotte
Abstract
We propose RepuScore, a collaborative reputation management
framework over email infrastrucure, which allows participating
organizations to establish sender accountability on the basis of
senders' past actions. RepuScore's generalized design can be deployed
with any Sender Authentication technique such as SPF, SenderID and
DKIM. With RepuScore, participating organizations collect information
on sender reputation locally from users or existing spam
classification mechanisms and submit it to a central RepuScore
authority. The central authority generates a global reputation summary
which can be used to enforce sender accountability. We present the
algorithms for reputation score calculation and share our findings
from experiments based on a RepuScore prototype using a) our
simulation logs and b) a 20 day log from a non-profit organization
with five collaborating domains.
