o Title:

User-Centric Security Systems to Empower Users' Authentication Decisions

o Abstract:

In today's Internet, authenticating online entities is challenging
since people lack the real-world cues upon which to base their
context-dependent trust decisions. For example, how can a user
confirm that a Facebook invitation truly originates from the claimed
sender, as anyone can trivially set up a bogus online identity with
someone else's photo? When downloading a piece of software, how can a
user ensure that the piece of software is what (s)he searched for, as
even security-conscious users are often frustrated by their inability
to judge the legitimacy of software? Unfortunately, automating trust
decisions is infeasible due to context-dependent nature of trust and
the delays in identifying new and evolving threats. Hence, users may
still be left alone to make trust decisions.

In this talk, I will demonstrate that providing useful evidence can
empower users to make informed context-dependent trust decisions using
two user-centric interfaces in the context of data and identity
authentications. I will first present a security system called Online
Trust Oracle (OTO) for data authentication. OTO presents two
categories of evidence to assist users in determining software
legitimacy: the positive evidence of why the software is safe to
download, and the negative evidence for potential malware. OTO's
additional trust evidence enables users to make correct trust
decisions even if the underlying operating system mistakenly
categorizes legitimate software as malicious and vice versa. I will
then introduce an identity authentication logic called RelationGrams
that visualize interpersonal tie strength of virtual entities using
both physical and social proximities. RelationGrams enable casual
users to authenticate online identities in a safe and easy manner, and
build trust in previously unknown online entities. As we discover in
user studies, OTO and RelationGrams are useful primitives that provide
situational awareness such that users can ultimately make appropriate
online trust decisions with confidence.
