Private Information Retrieval (PIR) is a well-known cryptographic primitive: When accessing some database records, the database server (as well as any external observer also seeing requests and replies) should not be able to learn which record has been requested. In this paper we demonstrate a way to achieve PIR in the context of Information Centric Networking (ICN). Our solution is able to conceal...
This article aims at evaluating the interest of the Wicri network, a network of semantic wikis, both as a reservoir of curation rules allowing to enrich corpora metadata and as a tool for parameterizing and supporting of instructions for the creation of corpora exploration servers. Starting, from the analysis of a bibliographic corpus extracted from different documentary databases, the experiments...
Sharing sensitive context information among multiple distributed components in mobile environments introduces major security concerns. The distributed sensing, processing and actuating components of these applications can be compromised and modified or impersonated to extract private and confidential information or to inject false information. In this paper we present the Anubis protocol for remote...
This paper describes the design and implementation of location and situation based adventure games. The prototype uses different types of sensor data - including 3D acceleration data and XPS - to determine the current positions and activities of the players. Depending on the continuous classification, data and quests are retrieved accordingly from a central information system and visualised for the...
The problem of inferring geographical information associated to web pages and identifying the geographic scope of their content is gaining increasing attention. However, geographic scope is a concept that can be interpreted in many different ways, ranging from the expected target scope of a specific content to the country where the content originated. The latter, in particular, albeit difficult to...
Most tourists today expect a friendly tour guidance and services considering their individual preferences and actual situation while protecting their privacy. The ideal is an intelligent guide taking care of the whole organization and execution in time. This is the main objective of the context-based Personalized Mobile Tourist Guide (PMTG). Tourist's profiles or visiting background is stored in a...
The software reuse initiatives are better implemented when there is an efficient way to find the reusable assets. However, the search and retrieval of such information is considered a big deal in literature, once there is a gap between what the software engineer would like to retrieve and what is stored in the repository. Thus, this paper presents an efficient way to reduce this problem and aid search...
This panel paper presents motivations for discussing mobile media search and contains statements from the panelists who are industry research leaders in this field.
This paper describes implementation of web-based hotel reservation system which enables users to book hotel rooms by means of a web browser. The system is based on JavaServer Faces technology in the presentation layer, Spring Framework in the service layer and iBatis library for the data access layer.
