Potential mass surveillance and privacy violations in proximity-based social applications.

Published in TRUSTCOM 15 Proceedings of the 2015 IEEE Trustcom/BigDataSE/ISPA, 2015

Proximity-based social applications let users interact with people that are currently close to them, by revealing some information about their preferences and whereabouts.

You never surf alone. Ubiquitous tracking of users’ browsing habits.

Published in Proceeding Revised Selected Papers of the 10th International Workshop on Data Privacy Management, and Security Assurance, 2015

In the early age of the internet users enjoyed a large level of anonymity. At the time web pages were just hypertext documents; almost no personalisation of the user experience was offered.

RESTful Rails Development: Building Open Applications and Services.

Published in OReilly Media, 2015

The Web is slowly but surely changing from a model in which a human reader browses content on web pages to a model in which services and clients (not necessarily humans) exchange information. And because of this, author Silvia Puglisi explains, it makes more sense to build platforms instead of just products or applications. Platforms are like ecosystems interconnecting different applications, services, users, developers, and partners, and offer many benefits.

Published in Ad Hoc Networking Workshop (Med-Hoc-Net), 2016 Mediterranean, 2016

Websites use personalisation services to profile their visitors, collect their in page reading activities and eventually use this data to provide tailored suggestions.

Analysis, Modelling and Protection of Online Private Data.

Published in Ph.D. dissertation, Universitat Politècnica de Catalunya, Jun. 2017, 2017

Websites and applications use personalisation services to profile their users, collect their patterns and activities and eventually use this data to provide tailored suggestions. User preferences and social interactions are therefore aggregated and Online communications generate a consistent amount of data flowing among users, services and applications. This information results from the interactions between different parties, and once collected, it is used for a variety of purposes, from marketing profiling to product recommendations, from news filtering to relationship suggestions.

Personal tracking devices.

Published:

In the post-NSA world it is important to understand the magnitude of our online activities in order to take informative decisions on our ubiquitous shared lives. Personal Tracking Devices is the result of a two years long study on tracking technologies and the inherent nature of the web and telecommunication networks in general. The study, conducted as part of Ph.D. research in privacy and security at UPC Barcelona Tech, collected a large amount of metadata to raise awareness on the footprints left by users on the web and through mobile apps.

Potential mass surveillance and privacy violations in proximity-based social applications.

Published:

Proximity-based social applications let users interact with people that are currently close to them, by revealing some information about their preferences and whereabouts. This information is acquired through passive geo-localisation and used to build a sense of serendipitous discovery of people, places and interests. Unfortunately, while this class of applications opens different interactions possibilities for people in urban settings, obtaining access to certain identity information could lead a possible privacy attacker to identify and follow a user in their movements in a specific period of time. The same information shared through the platform could also help an attacker to link the victim’s online profiles to physical identities. We analyse a set of popular dating application that shares users relative distances within a certain radius and show how, by using the information shared on these platforms, it is possible to formalise a multilateration attack, able to identify the user actual position. The same attack can also be used to follow a user in all their movements within a certain period of time, therefore identifying their habits and Points of Interest across the city. Furthermore we introduce a social attack which uses common Facebook likes to profile a person and finally identify their real identity.

You never surf alone. Ubiquitous tracking of users’ browsing habits.

Published:

In the early age of the internet users enjoyed a large level of anonymity. At the time web pages were just hypertext documents; almost no personalisation of the user experience was offered. The Web today has evolved as a world wide distributed system following specific architectural paradigms. On the web now, an enormous quantity of user generated data is shared and consumed by a network of applications and services, reasoning upon users expressed preferences and their social and physical connections. Advertising networks follow users’ browsing habits while they surf the web, continuously collecting their traces and surfing patterns. We analyse how users tracking happens on the web by measuring their online footprint and estimating how quickly advertising networks are able to profile users by their browsing habits.
