Intentionality and Agency in Security
Weiser [13] said that the best software is that which just blends in and disap- pears. Security software has been at odds with this principle as it attempts to attract user attention whenever possibleâit has been largely designed to be visible to the user and ask them to take action. For example, anti-virus software proudly notifies the user how many viruses it has stopped while websites dis- play padlocks and security seals. Users are disrupted in their work by security notifications, asked to read warnings and decide whether they want to heed or ignore them.ERC 30722

Bootstrapping adoption of the Pico password replacement system
In previous work we presented Pico, an authentication sys- tem designed to be both more usable and more secure than passwords. One unsolved problem was that Pico, in its quest to explore the whole solution space without being bound by compatibility shackles, requires changes at both the prover and the verifier, which makes it hard to convince anyone to adopt it: users wonât buy an authentication gadget that doesnât let them log into anything and service providers wonât sup- port a system that no users are equipped to log in with. In this paper we present three measures to break this vicious circle, starting with the âPico Lensâ browser add-on that rewrites websites on the fly so that they appear Pico-enabled. Our add-on offers the user most (though not all) of the usability and security benefits of Pico, thus fostering adoption from users even before service providers are on board. This will enable Pico to build up a user base. We also developed a server-side Wordpress plugin which can serve both as a reference example and as a useful enabler in its own right (as Wordpress is one of the leading content management platforms on the web). Finally, we developed a software version of the Pico client running on a smartphone, the Pico App, so that people can try out Pico (at the price of slightly reduced security) without having to acquire and carry another gadget. Having broken the vicious circle weâll be in a stronger position to persuade providers to offer support for Pico in parallel with passwords.ERC 30722
SymbioCity: Smart Cities for Smarter Networks
The "Smart City" (SC) concept revolves around the idea of embodying
cutting-edge ICT solutions in the very fabric of future cities, in order to
offer new and better services to citizens while lowering the city management
costs, both in monetary, social, and environmental terms. In this framework,
communication technologies are perceived as subservient to the SC services,
providing the means to collect and process the data needed to make the services
function. In this paper, we propose a new vision in which technology and SC
services are designed to take advantage of each other in a symbiotic manner.
According to this new paradigm, which we call "SymbioCity", SC services can
indeed be exploited to improve the performance of the same communication
systems that provide them with data. Suggestive examples of this symbiotic
ecosystem are discussed in the paper. The dissertation is then substantiated in
a proof-of-concept case study, where we show how the traffic monitoring service
provided by the London Smart City initiative can be used to predict the density
of users in a certain zone and optimize the cellular service in that area.Comment: 14 pages, submitted for publication to ETT Transactions on Emerging
