abstract = {Modern scalable coding techniques, as H264 SVC, are adequate to save processing power and bandwidth. Moreover, if the enhancements of a SVC encoded content are protected, it is possible to enable pay-per-quality systems. Transcoding and protection entail huge doses of processing power at provider side and should be distributed. Moreover, processing key streams to decrypt enhancements that were encrypted separately can increase the complexity at receiver side. This abstract describes a distributed system for content encoding and protection that generates a flexible key stream that simplifies the receiver.},

abstract = {Passwords are an often unavoidable authentication mechanism, despite the availability of additional alternative means. In the case of smartphones, usability problems are aggravated because interaction happens through small screens and multilayer keyboards. While password managers (PMs) can improve this situation and contribute to hardening security, their adoption is far from widespread. To understand the underlying reasons, we conducted the first empirical usability study of mobile PMs, covering both quantitative and qualitative evaluations. Our findings show that popular PMs are barely acceptable according to the standard System Usability Scale, and that there are three key areas for improvement: integration with external applications, security, and user guidance and interaction. We build on the collected evidence to suggest recommendations that can fill this gap.},

For this reason, this paper describes a vulnerability study on one of the most popular fitness trackers in 2017, together with the mobile application associated to the tracker.

abstract = {IoT devices provide with real-time data to a rich ecosystems of services and applications that will be of uttermost importance for ubiquitous computing. The volume of data and the involved subscribe/notify signaling will likely become a challenge also for access and core netkworks. Designers may opt for microservice architectures and fog computing to address this challenge while offering the required flexibility for the main players of ubiquitous computing: nomadic users. Microservices require strong security support for Fog computing, to rely on nodes in the boundary of the network for secure data collection and processing. IoT low cost devices face outdated certificates and security support, due to the elapsed time from manufacture to deployment. In this paper we propose a solution based on microservice architectures and DNSSEC, DANE and chameleon signatures to overcome these difficulties. We will show how trap doors included in the certificates allow a secure and flexible delegation for off-loading data collection and processing to the fog. The main result is showing this requires minimal manufacture device configuration, thanks to DNSSEC support.},

abstract = {Privacy rules imposed by social networks (SNs) impose several restrictions to user privacy. Though they usually offer the user some control to limit access to his own data, the social network may share uploaded data with other partners and marketing companies. Pictures and videos may have a second life, even after being deleted by the user, and consequently storage and access must take place in the user home domain or facilities managed by the user, following an end to end approach. We propose to combine the usage of private clouds, specialized in media contents, in cooperation with SNs, offering the user complete control over his data, while benefiting from the SNs visibility to announce and spread the data. To achieve transparency, we propose a plug-in system to embed links as annotations in reduced media replacement uploaded in the SN. These links point to the real resource stored in the private cloud, now under complete user control. We perform validation tests which show important improvements in uploading time and user experience.},

abstract = {Privacy is a very complex and subjective concept with different meaning to different people. The meaning depends on the context. Moreover, privacy is close to the user information and thus, present in any ubiquitous computing scenario. In the context of identity management (IdM), privacy is gaining more importance since IdM systems deal with services that requires sharing attributes belonging to users’ identity with different entities across domains. Consequently, privacy is a fundamental aspect to be addressed by IdM to protect the exchange of user attributes between services and identity providers across different networks and security domains in pervasive computing. However, problems such as the effective revocation consent, have not been fully addressed. Furthermore, privacy depends heavily on users and applications requiring some degree of flexibility. This paper analyzes the main current identity models, as well as the privacy support presented by the identity management frameworks. After the main limitations are identified, we propose a delegation protocol for the SAML standard in order to enhance the revocation consent within healthcare scenarios.},

However, when consuming those contents outside a home environment some problems should be addressed as dealing with limited devices and protecting user generated and commercial contents from eavesdroppers. This article describes a solution that enables limited devices to access contents located in private clouds, as Media Cloud, with the cooperation of network providers.},

abstract = {User centricity is important when designing new products and services. Automatic personalization emerges as key feature to prevent users from being bothered by complex management tasks, allowing them to get the most from their devices. However, devices within home environments are shared among family members, making personalization complex. This article describes a system that uses presence detection through several low cost cameras. It uses a centralized repository for personalization and an event based protocol for configuring devices surrounding users. The system addresses privacy-based filtering and group preference modeling.},

abstract = {Video conference services have been there for quite a long time. First commercial services, enabled by ISDN, where mainly operated by Telcos, then IP enabled video conference and multiconference through the session description protocol (IETF RFC 4566). The common explanation why these services were not massively adopted was price, bandwidth limitation and poor usability. Today bandwidth has greatly improved thanks to ADSL penetration, and many free and commercial providers offer more usable video conference services. Still these services are not massively adopted by domestic users. We also base on the hypothesis that video conference integration with social networks and home networks, will dramatically improve usability and market, but we consider that both integration and usability will be greatly increased through flexible consumer electronics. In this article we explain the requirements of such a device, its architecture, and the advantages for users and technology adoption.},

abstract = {Since the advent of the digital era, the traditional TV scenario has rapidly evolved towards an ecosystem comprised of a myriad of services, applications, channels, and contents. As a direct consequence, the amount of available information and configuration options targeted at today's end consumers have become unmanageable. Thus, personalization and usability emerge as indispensable elements to improve our content-overloaded digital homes. With these requirements in mind, we present a way to combine content adaptation paradigms together with presence detection in order to allow a seamless and personalized entertainment experience when watching TV.},

abstract = {Mobile and online DTV encourages new scenarios and applications to dynamically share content or delegate services between user's personal devices and networks. This requires the establishment of federations in a dynamic way, emerging the trust management as an important facet for that. Such trust management should be autonomous, user-centric, and dynamic to cope with forthcoming applications. This article addresses the mentioned requirements, by defining a SAML-compliant enhanced client to support federated environments for cooperation in mobile DTV scenarios. Such client is extended with a trust layer inside consumer electronic devices' software.},

abstract = {With the rapid evolution of networks and the widespread penetration of mobile devices with increasing capabilities, that have already become a commodity, we are getting a step closer to ubiquity. Thus, we are moving a great part of our lives from the physical world to the online world, i.e. social interactions, business transactions, relations with government administrations, etc. However, while identity verification is easy to handle in the real world, there are many unsolved challenges when dealing with digital identity management, especially due to the lack of user awareness when it comes to privacy. Thus, with the aim to enhance the navigation experience and security in multiservice and multiprovider environments the user must be empowered to control how her attributes are shared and disclosed between different domains.With these goals on mind, we leverage the benefits of the Infocard technology and introduce this usercentric paradigm into the emerging NGN architectures. This paper proposes a way to combine the gains of a SAML federation between service and identity providers with the easiness for the final user of the Inforcard System using the well known architectural schema of IP Multimedia Subsystem.},

abstract = {Federation has emerged as a key concept for identity management, as it is the basis to reduce complexity in the companies and improve user experience. However, the problem of establishing identity federations in dynamic open environments, where it is desirable to speed up the processes of service provisioning and deprovisioning, has not been fully addressed. This paper reviews the existing frameworks for identity federation, analyzing the underlying trust mechanisms and its suitability to be applied in the mentioned environments. Finally, we propose a generic extension for the Security Assertion Markup Language (SAML) standard in order to facilitate the creation of federation relationships in a secure dynamic way between prior unknown parties.},
