面向电子政务网络建设的信任互联管控模型

电子政务随着国家信息化发展而不断演进,电子政务网络安全成为信息安全的重要研究领域.然而,传统的局域网或互联模式不能适应我国电子政务网络分区分域的管理需求.虽然美国IATF理论在安全架构设计上虽有一定借鉴作用,但不能很好适应于我国电子政务网络特征和安全管理要求.当前,我国电子政务网络呈现出“分层分域的安全防护结构、分级分类的受控访问要求、分级负责的安全管理模式”3个基本特征.通过深入研究分析我国电子政务网络的现状和特征,提出了我国电子政务网络安全的信任互联管控(TIC)模型.分别阐述了电子政务网络安全TIC模型的3种具体设计：对等互联模型、层级互联模型和混合互联模型,并对跨域信任传递、域间安全监管和全程策略管控等关键技术进行了设计.最后,采用层次分析法(analytic hierarchy process, AHP)对TIC模型进行了评估.评估结果表明：在复杂的电子政务网络中,TIC模型可以适合于电子政务网络安全的架构设计,其关键技术能够为建立电子政务网络的安全体系及相关产品研制提供重要的参考借鉴.

Measuring e-government readiness

We proposed a way of assessing readiness of a government organization to transform itself into a provider of fully integrated e-government services. We identified major components of e-government and discussed how it could evolve from a simple website into a fully integrated portal that delivers services to the public. Drawing upon strategic IS theory, we proposed three levels – strategic, system, and data – at which the governmental office’s readiness for e-government should be addressed. We empirically tested our model of e-government readiness with data collected from a U.S. municipal government. However, the results supported only a two-level model rather than the three we had theorized. This finding had important implications because it supported our contention that discrepancies can occur when e-government initiatives are at a relatively early stage and some critical e-government issues have not yet emerged.     

User engagement in e-government systems implementation: A comparative case study of two Singaporean e-government initiatives

Noting that user engagement is a key issue in e-government systems implementation and that the actual form and strategies of user engagement, especially within the context of e-government, is poorly defined, this paper intends to contribute to the research and practice of e-government systems implementation by conducting a comparative case study of two e-government systems implementation within a single government agency in Singapore. The comparative analysis of these two e-government systems implementation was accomplished through using stakeholder theory as a sense-making theoretical lens. This generated four findings pertaining to the form and strategies of user engagement in e-government systems implementation.

Benchmarking E-Government

E-government benchmarking reports are characterized by their multitude as well as by the dissimilarity of the approaches applied to assessing development. This article will present and compare the research methods and the main results of four selected e-government benchmarking series. Built in this remarks the authors raise the question whether these reports are able to contribute to the realization of benefits inherent in the benchmarking of e-government. It will be demonstrated, that depending on the specification of different system parameters benchmarking series show varying relevance for governments seeking to exercise certain functions. Subsequent to this functional analysis the authors will discuss whether these reports represent an appropriate foundation for governments striving for the implementation of e-government designed in a comprehensive and sustainable manner. For this purpose key elements of e-government are brought together into a holistic evaluation model. Based on this comprehensive approach it is argued that the functionality of the presented benchmarking reports remains confined to certain elements of e-government as well as to certain stakeholders’ views.

Semantic processing of multimedia data for e-government applications

Knowledge management has become a challenge for almost all e-government applications where the efficient processing of large amounts of data is still a critical issue. In the last years, semantic techniques have been introduced to improve the full automatic digitalization process of documents, in order to facilitate the access to the information embedded in very large document repositories. In this paper, we present a novel model for multimedia digital documents aiming at improve effectiveness of digitalization activities within an information system supporting e-government organizations. At the best of our knowledge, the proposed model is one of the first attempts to give a single and unified characterization of multimedia documents managed by e-government applications, whereas semantic procedures and multimedia facilities are used for the transformation of unstructured documents into structured information. Furthermore, we define an architecture for the management of multimedia documents “life cycle”, which provides advanced functionalities for information extraction, semantic retrieval, indexing, storage, presentation, together with long-term preservation. Preliminary experiments concerning an e-health scenario are finally presented and discussed.

Business Processes Verification for e-Government Service Delivery

Domain experts knowledge represents a major source of information in the design and the development of user-centric and distributed service-based applications, such as those of e-government. Issues related both to the communication among domain and IT experts, and to the implementation of domain dependent requirements in service-based applications, have to be carefully considered to support both Public Administrations efficiency and citizen satisfaction. In this article, we provide as user-friendly approach toward business process assessment via formal verification. Starting from a semi-formal notation, well understood and largely used by domain experts, we provide a mapping to a formal specification in the form of a process algebra. This transformation makes possible formal and automatic verification of desired quality requirements. The approach has been already applied, with encouraging results, in the e-government domain to verify the quality of business processes related to the delivery of e-government digital services to citizens. Moreover, the approach is supported by a plug-in for the Eclipse platform permitting to have an integrated environment in which to design the process model and to assess its quality.
