E-polling systems are a fundamental component of any e-democracy system as they represent the most appropriate tool for fostering citizens participation to public debates. Contrarily to e-voting protocols, they are characterized by less stringent security requirements in particular they can tolerate errors affecting a small percentage of votes, without the compromision of the final result. Thus the construction of accurate and privacy respectful e-polling protocols is an objective which should be pursued by the research community as it is more close than the construction of practical e-voting protocols. However so far all the research efforts have been spent on the construction of e-voting protocols and the existing e-polling protocols are not respectful of the most elementary security and privacy rules. In this paper we propose a simple protocol for an accurate and anonymous e-polling system. More precisely our protocol satisfies the following properties: a vote cannot be altered, duplicated, or removed without being detected, votes remain anonymous. Moreover voters will be able to measure the level of trust of the process and its accuracy by verifying that their own votes have been counted correctly.

Model Driven Architecture is an approach to increase the quality of complex software systems by creating high-level system models and automatically generating system architectures and components out of these models. We show how this paradigm can be applied to what we call Model Driven Security for inter-organizational workflows in e-government. Our focus is on the realization of security-critical inter-organizational workflows in the context of web services and web service orchestration. Security requirements are specified at an abstract level using UML diagrams. Out of this specification security relevant artifacts are created for the target reference architecture based on upcoming web service security standards.

The requirement of integrating, sharing and reusing legislative information is a research issue gaining priority for governments and institutions. The legal world is complex, heterogeneous and wide in scope. Therefore, we find convenient to define ontologies as a tool to decrease this complexity inherent to the legal domain. This paper is based on the () built for the and that is successfully running since 1999. In this context, we describe how manages the that arrives to a Parliament. Later, we propose an ontology in order to describe the , called . This conceptually models theincluding the structure of the Emendations to this and is connected with the act of making and passing laws. So, this makes easier the organizing task in the and, in general, all the Legislative procedural steps. Besides, this ontology could be offered as a basis for other parliamentary systems (as) to improve their procedures.

Citizens have never had complete and up-to-date information on all the laws, regulations and opportunities that concern them. Although the law does not excuse ignorance, information-publishing techniques, usually Official Gazettes on paper, make effective knowledge and awareness virtually impossible. One of the greatest opportunities of e-government is to overcome this information gap and to supply timely and complete information to everybody. The electronic availability of information is but a minor aspect of this problem. Rather, effective, timely and accurate ways of disseminating information must be found. We discuss several solutions, ranging from text retrieval to ontologies and agents, and focus on dynamic taxonomies, a model recently proposed for the intelligent exploration of heterogeneous information bases, that can provide guided browsing and personalized exploration for complex laws and regulations.

As software processes for developing eGovernment services become more complex, it is necessary to provide computer-based tools to support the software engineering process. Furthermore, actions should be taken to limit the loss of critical knowledge during the life cycle of eGovernment services. In this paper we first illustrate the overall architecture of ONTOGOV, an under-development software engineering environment for developing and managing the life-cycle of eGovernment services. We then outline two ontologies upon which ONTOGOV is based. Finally, an application scenario is described and the paper concludes with the identification of further steps and research directions.

A big challenge for governments all over the world is to improve the service provisioning to their clients, citizens and businesses. One way of improving service-provisioning is by means of a a one-stop-shop that integrates services that are performed by different semi autonomous agencies. This requires the coordination of service-delivery processes that run across different agencies. This is also called process orchestration. As little is known about process orchestrators, governmental decision-makers need support in designing them. This paper investigates the applicability of existing reference models from domains that are closely related to process orchestration, the Workflow Reference Model and the extended SOA reference model, to governmental decision-makers for implementing process orchestration in e-government, and identifies several main requirements for a reference mode for process orchestration, based on a case study performed at a business counter.

In the last few years the Government discipline has attracted a growing attention both from practitioners and academics. Although the high number of action plan, projects and conferences spread all over Europe seems sanctioning the achievement of its maturity stage, several organizational and technological issues related with the modernization of service delivery are still far from a comprehensive solution and still require significant efforts. In this paper, the approach followed and the results so far achieved within the Eu-Publi.com research project, are presented. The discussion on the conceptual and design architectures of the Eu-Publi.com distributed, peer-to-peer system is enriched with results about the experimentation conducted on one of its core components.

In order to provide citizens with quality services, respecting public administrations autonomy, we propose a new concept of eGovernment Service Marketplace (eGovSM). This paper presents an overview of the architecture and implementation of eGovSM easing the automatisation of administrative process involving several administrations and allowing the reuse of data. This architecture facilitates citizens’ interaction with different public administrations by providing them a single and personalized access point to services. The eGovSM is formalized using a set of XML Schema models in order to support the realization of an interoperable and open system. The architecture is based on four main functional modules: UNICITIDM (UNIiversal CITizen IDentifier Manager) a module for the creation and management of citizen unique identifiers, LEM (Life Event Manager) for the management of all citizen interactions with the marketplace, DM (Document Manager) for the management of administrative process execution and SM (Service Manager) for the management of all public administrations interactions with eGovSM.

This paper introduces the goal of ShanghaiGrid and its sub-project E-government on the Grid. The main existing problem of the E-government is how to integrate each government agency’s resources to form cross-agency services for citizens. Grid technique provides an ideal way to solve this problem. The workflow middleware, transaction middleware, and the real-name citizen mailbox are discussed in detail.

During the last years, governmental organizations have invested considerable effort and financial resources in the development and adoption of e-government services. In order to sustain the quality of their services, governmental organizations need to solve the problem of efficient and secure electronic exchange and processing of governmental documents and data. A major difficulty in this distributed deployment is the fact that these interconnected systems are heterogeneous and they may operate in multiple organisational domains. This paper demonstrates how the ISO/RM-ODP standard offers a general framework to design and develop an open distributed system attuned to e-government environments. This is subsequently supported by a high level case study of how this standard can be applied in the case of a system designed for small to medium sized European municipalities.
