A Smart Assistant for Visual Recognition of Painted Scenes
Nowadays, smart devices allow people to easily interact with the surrounding environment thanks to existing communication infrastructures, i.e., 3G/4G/5G or WiFi. In the context of a smart museum, data shared by visitors can be used to provide innovative services aimed to improve their cultural experience. In this paper, we consider as case study the painted wooden ceiling of the Sala Magna of Palazzo Chiaramonte in Palermo, Italy and we present an intelligent system that visitors can use to automatically get a description of the scenes they are interested in by simply pointing their smartphones to them. As compared to traditional applications, this system completely eliminates the need for…
Improving user experience via motion sensors in an Ambient Intelligence scenario
Ambient Intelligence (AmI) is a new paradigm in Artificial Intelligence that aims at exploiting the information about the environment state in order to adapt it to the user preferences. AmI systems are usually based on several cheap and unobtrusive sensing devices that allow for continuous monitoring in different scenarios. In this work we present a gesture recognition module for the management of an office environment using a motion sensor device, namely Microsoft Kinect, as the primary interface between the user and the AmI system. The proposed gesture recognition method is based on both RGB and depth information for detecting the hand of the user and a fuzzy rule for determining the stat…
Secure e-voting in smart communities
Nowadays, digital voting systems are growing in importance. This is an especially sensitive area, because elections can directly affect democratic life of many smart communities. The goal of digital voting systems is to exploit ICT technologies to improve the security and usability of traditional electoral systems. In this work we present a secure electronic voting system that guarantees the secrecy, anonymity, integrity, uniqueness and authenticity of votes, while offering a user-friendly experience to voters, putting them at ease through the use of technologies familiar to them. To ensure these fundamental security requirements, the system fully separates the registration and voting phase…
Twitter spam account detection by effective labeling
In the last years, the widespread diffusion of Online Social Networks (OSNs) has enabled new forms of communications that make it easier for people to interact remotely. Unfortunately, one of the first consequences of such a popularity is the increasing number of malicious users who sign-up and use OSNs for non-legit activities. In this paper we focus on spam detection, and present some preliminary results of a system that aims at speeding up the creation of a large-scale annotated dataset for spam account detection on Twitter. To this aim, two different algorithms capable of capturing the spammer behaviors, i.e., to share malicious urls and recurrent contents, are exploited. Experimental r…
