Enabling personalised medical support for chronic disease management through a hybrid robot-cloud approach

Abstract: Information and Communication Technology and personal robots could play a fundamental role in efficiently managing chronic diseases and avoiding improper medications. They could support senior citizens with reminders, thus promoting their independent living and quality of life, especially in the presence of several chronic diseases (multimorbidity). In this context, this article proposes a service model for personalised medical support that is able to provide adequate healthcare service by means of a hybrid robot-cloud approach. This service was quantitatively and qualitatively tested to assess the technical feasibility and user acceptability level of the service. The service was tested with 23 older people (65---86 years) in the DomoCasa Lab (Italy). This study demonstrated the feasibility of the proposed hybrid cloud solution and the usability and acceptability were positively evaluated thus confirming the ability to utilise these innovative technologies for active and healthy ageing.

Intrinsic Statistical Weakness of Keystream Generators

Abstract: It is shown that an arbitrary binary keystream generator with M bits of memory can be linearly modelled as a non-autonomous linear feedback shift register of length at most M with an additive input sequence of nonbalanced identically distributed binary random variables. An effective method for the linear model determination based on the linear sequential circuit approximation of autonomous finite-state machines is developed. Linear models for clock-controlled shift registers and arbitrary shift register based keystream generators are derived. Several examples including the time-variant memoryless combiner, the basic summation generator, the stop-and-go cascade, and the shrinking generator are presented. Linear models are the basis for a general structure-dependent and initial-state-independent statistical test and they may also be used for correlation attacks on the initial-state. Theoretical security against the introduced statistical attack appears hard to control in practice and hard to achieve with simple schemes.

The Context API in the OMA Next Generation Service Interface

Abstract: Application Platforms and related APIs are becoming the foundations for emerging eco-systems of online applications/services. End-users are more and more choosing devices and services based on the available offers in the respective eco-system. Attracting and retaining application developers and end-users to a networked platform is nowadays more and more depending on the features available to developers in the form of APIs and (e.g. cloud-based) execution environments rather than on the actual portfolio of services. The Open Mobile Alliance (OMA) Next Generation Service Interfaces (NGSI) is one cornerstone of evolving a network operator towards an application platform provider with open APIs. Within NGSI, the Context API enables access to a plethora of rich information about users, places, events, and things - all made available by or brokered through the network operator. This paper explains the OMA NGSI Context API and its rationale, describes the operations, and discusses typical use cases and benefits it can bring to operators and application developers.

Method and system for providing access to web services

Abstract: Software applications are provided access to web services, such as Parlay X web services, by providing a Parlay gateway (PG) permitting access to web services and including a Parlay framework (FW). A set of modules (PX WS) comprising service interfaces for the software applications is provided, the modules (PX WS) in the set acting as proxies in order to perform requests for access to web services on the framework (FW) of the Parlay gateway on behalf of the software applications.

Peer-to-peer overlays for real-time communication: security issues and solutions

Abstract: Peer to peer (P2P) networks offer higher robustness against failure, easier configuration and are generally more economical as compared to their client-server counterparts. This has made it reasonable for resource consuming and typically centralized applications like voice over IP (VoIP) and, in general, real-time communication to adapt and exploit the benefits of P2P. Such a migration needs to address a new set of P2P specific security problems. We go over some of the known issues found in common P2P networks. We then analyze the relevance of such issues and the applicability of existing solutions when using P2P architectures for real-time communication.
