Security and Performance of Mobile XML Web Services

隨著金融管制解除及電子商務時代的來臨，金融服務業的經營環境有了巨大的變化；為了生存與成長，金融服務業者必需不斷地創思新構想、推出新金融商品。惟實證研究顯示，新金融商品推出的成功率一直不高。新金融商品失敗所造成的直接財務損失可能不高，但仍有許多隱藏成本。如何改善金融服務業者的新服務開發(new service development, NSD)績效呢？這是金融業者高階主管及學術界所關心的問題。目前已有研究探討金融服務業的新產品成功因素，惟這些研究多僅以單一問項來衡量績效，未考量新金融商品績效的多構面特性。此外，這些研究多以探索性統計分析方法檢測NSD活動與新金融商品績效的關聯。再者，許多研究探討NSD活動及NSD效果（如服務/市場配適、行銷溝通效果）對新金融商品績效的影響，惟至今尚乏研究探討NSD活動與NSD效果的因果關聯。 本研究首先透過文獻分析將新金融商品績效歸納為兩個構面—直接績效及間接績效，將可能影響新金融商品績效的因素歸納為NSD行銷活動（包括市場研究、人員訓練、試銷、上市準備與推出）、及NSD效果（包括服務／市場配適、服務獨特卓越性、行銷溝通效果），其次推論NSD行銷活動執行品質對NSD效果之影響、NSD效果對新金融商品績效的影響、服務／市場特性對「NSD效果與新金融商品績效關聯」的干擾效果，並以國內銀行業及保險業的93個新金融商品開發專案為實證對象。 本研究之假設推論以層級迴歸及節制迴歸驗證。分析結果顯示，(1) NSD行銷活動中以上市準備與推出對NSD效果的影響最大，其次為市場研究，試銷活動的影響最小。(2) NSD效果中以行銷溝通效果對新金融商品績效的影響最大，其次為產品／市場配適，服務獨特卓越性顯得並不重要。(3) 「NSD效果與新金融商品間接績效的關聯」受到產品對市場的新穎性、市場競爭度、市場對公司新穎性的干擾。最後，研究者對實證結果在新金融商品開發管理涵義及後續研究做一些討論與建議。

The purpose of this paper is to establish Customer Relationship Management (CRM) as an effective approach for collecting, analyzing, and translating valuable customer information into managerial action for examining fast track legal systems i.e., Online Public Grievance Redressal System (OPGRS) in the Indian context. This e-government initiative is based on the government's long term strategic policy that aims to innovatively reform the Indian Judicial System. So far, the potential of CRM has been investigated only in the context of existing products/ services. CRM's potential to aid in future New Service Development (NSD) has been under studied. Current research model is based on Resource Advantage (R-A) theory and includes the constructs such as CRM process, CRM technology, New Service Development, system efficiency, performance expectancy and effort expectancy under one umbrella. It measures CRM Process under the dimensions of; innovation management, value management and multiple channel management. This model has been tested based on applications filed at multi source complaint depository consisting of 173 applicants from diverse case backgrounds. The empirical outcome provides the positive significant relationships for all 5 hypotheses established using nine (9) constructs. The results provide evidence that CRM has a positive effect on new service performance.

Native Web communication protocols are the pivotal components of Web services, applications and systems. In particular, HTTP is a de facto protocol standard used in almost all Web services and systems. Consequently, it is one of the crucial protocols responsible for the performance of Web services and systems. HTTP/1.1 has been successfully deployed in Web services and systems for the last two decades. However, one of the most significant issues with HTTP/1.1 is the Round Trip Time and Web latency. To resolve this issue, two successor protocols SPDY and HTTP/2 have been developed recently, with some studies suggesting that SPDY improved the performance of Web services and systems, whilst some did not find significant improvements in the performance. HTTP/2 is a relatively new protocol and has yet to be tested with any rigour. Therefore, it is important to investigate the effects of these two enhanced protocols SPDY and HTTP/2 on the performance of Web services and systems. This paper conducts a number of practical investigations to evaluate the performance of Web services and systems with and without the support of SPDY and HTTP/2 protocols at the client and server. This study investigates the impact of SPDY and HTTP/2 on the overall performance of Web services and systems from the end-user's perspective.

Mobile methadone medication units: A brief history, scoping review and research opportunity

With the great development of mobile services, the Quality of Services (QoS) becomes an essential factor to meet end users’ personalized requirement on the nonfunctional performance of mobile services. However, most of the QoS values in real cases are unattainable because a service user would only invoke some specific mobile services. Therefore, how to predict the missing QoS values and recommend high-quality services to end users becomes a significant challenge in mobile service recommendation research. Previous QoS prediction researches demonstrate that the nonfunctional performance of mobile services is closely related to users’ location information. However, most location-aware QoS prediction methods ignore the premise that the obtainable QoS values observed by different users in same location region would probably be untrustworthy, which will lead to inaccurate and unreliable prediction results. To make credible location-aware QoS prediction, we propose a hybrid matrix factorization method integrated location and reputation information (LRMF) to predict the unattainable QoS values. Our approach firstly cluster users into different locational region based on their geographical distribution, and then we compute users’ reputation to identify untrustworthy users in every locational region. Finally, the unknown QoS values can be predicted by integrating locational cluster information and users’ reputation into a hybrid matrix factorization model. Comprehensive experiments are conducted on a public QoS dataset which contains sufficient real-world service invocation records. The evaluation results indicate that our LRMF method can effectively reduce the impact of unreliable users on QoS prediction and make credible mobile service recommendation.

Interorganisational new service development capability in the mobile communications ecosystem

In this paper, a design of a security system for portable drive is proposed using ECC to secure XML web service and associated application. An XML web service component is integrated with existing VPN gateway to provide security solution for both the XML web service and traditional network-based application. Both share the same digital ECC key, which is utilized by the XML Web Service security component. The high level design of the SSL VPN on a portable device helps in connecting the peer to peer network. It secures the data transmission over the entire network route from the client to the remote server, and effectively improves the data processing speed of the server. The design is experimented with customized java coding and its performance is analyzed and compared with existing scheme in which the RSA is used. The design is found to be more secure and faster based on the preliminary results.KeywordsSSL VPNXMLWeb Services securityElliptic Curve CryptographyPortable device

User involvement in New Service Development(NSD) has attracted the limelight as a good method, but we still lack an empirical analysis of the effectiveness of user involvement. In addition, positive and negative determinants of user involvement in NSD have not often been dealt with in past research, and this deficiency has been identified as a barrier to the effective utilization and diffusion of user involvement in NSD. To our knowledge, this is the first study to empirically investigate the degree of implementation of user involvement in NSD, the effectiveness of user involvement, and the utilization strategy in the digital content industry. First, we reveal that ordinary user involvement is more effective for NSP performance than lead users or business partner companies. Second, we empirically demonstrate that the effectiveness of involving lead user and ordinary user in NSP is different according to the new service type and service development stage. Based on the results of our analyses, we suggest some strategic directions for the companies who want to newly adopt or improve their current level of user involvement in NSD. We expect that the implications of this study will be utilized for efficient diffusion of user involvement in NSD and will eventually contribute to tangible achievements for companies in the digital content industry.

Simple object access protocol (SOAP) is the communication protocol used by web services to communicate between systems. Since SOAP messages have the ability to bypass firewalls and directly get processed by web servers, their security is critical to the security of the web servers. Secure transit of SOAP messages plays a critical role for the applicability of web services. At present, internet users authenticate themselves using credential are vulnerable to security threats in presence of active attackers. This imposes a burden on users to manage their credentials in different ways. Along with the thorough development and application for web services, the security of it has taken people's attention more and more. While web services security (WSS) can exchange safe SOAP message and enhance the security of web services, it will also have certain influence to the performance of web services. This paper explore the security vulnerability of SOAP message transaction and taking advantage of the existing technologies and solutions related to SOAP and web services, we developing a highly developed security model. This model is useful for solving the problem between security and performance contradiction.

The usability of mobile services is degraded while moving, since users cannot pay enough attention to the services in such dynamic and complicated mobile environments. Mobile and wearable services should be appropriately designed to handle human factor issues, otherwise fine user experiences cannot be offered. In this paper, we discuss design issues in mobile service development from a human factor point of view, and propose a design framework to overcome the challenges. Our approach provides two interaction modes (i.e. simple interaction mode and normal interaction mode) to mobile services, in order to allow a user to keep using the service without frequent interruptions while moving. Also, a service's events are simplified in order to support several modalities so that a user can be notified in the most suitable way according to the situation. To evaluate the feasibility of our approach in field experiments, we developed a pedestrian navigation service as a part of the framework. The results showed that the simple interaction mode successfully decreased a user's cognitive load to the service. Also, future directions for further improvements are discussed based on comments and feedbacks.

This paper describes the design and development of an application-based mobile service and offers both theoretical and empirical contributions relating to the consumers' motives for and barriers to adopting mobile services. A case study based on a mobile Java-based approach for providing mobile services is introduced to gain insights into mobile service development process and to validate the factors that influence the acceptance of mobile services in Finland. Based on the findings from a survey conducted with a sample of 52 Finnish campus students, the factors that affect consumers' attitudes towards mobile services were discovered. Usefulness was revealed to have the strongest impact on attitude towards a mobile service, with contextual information and attitude acting as significant determinants of the intention to use the service. This study attempts to help mobile service providers choose right development and marketing strategies for mobile services and accelerate the diffusion of services.

The transport sector is one of the sectors that has been greatly influenced by the 4th Industrial Revolution through the development of New Mobility Services (NMS). NMS include innovative transport modes, such as autonomous road vehicles, and new concepts for serving mobility needs, such as Mobility as a Service, which are gradually being implemented in cities of Europe and worldwide. As part of the implementation of the European Union’s (EU) Green Deal, the EU strategy for transportation and mobility sets specific ambitions and targets regarding NMS and their contribution to sustainable urban development. The core documents outlining the relevant EU strategy comprise the “Sustainable and Smart Mobility Strategy – putting European transport on track for the future” (COM(2020) 789 final) and “The New EU Urban Mobility Framework” (COM(2021) 811 final). In this context, the purpose of the current paper is the comprehensive description of the EU policy priorities for the implementation of NMS, deriving from the synthetic analysis of the information presented in the above-mentioned policy documents. The paper also aims at the discussion of challenges from the perspective of planning for urban mobility in Greek cities, such as the attachment to the private car for daily mobility, the necessity for data exchange and cooperation between stakeholders and the need for a long-term vision for sustainable urban development. Taking into account the overall policy objectives at the EU level and the challenges for pursuing these objectives to achieve the digital and green transition of Greek cities, the paper concludes with the suggestion of planning recommendations to integrate NMS into their urban transport system with a positive impact on their ongoing effort for the “sustainable mobility paradigm” shift. These recommendations mainly refer to the application of contemporary planning approaches, such as participatory planning, interdiscipl nary cooperation and evidence-based planning, with focus on the issue of NMS implementation at the urban level. The issues discussed in the current paper directly concern planners and policy makers in urban areas of Greece, while they can be appropriately adjusted to the considerations of stakeholders in other cities. They can also provide the background to develop case- specific methodological processes to address the planning needs for the integration of NMS to a particular city.
