User Perceived Quality Model for Web-Based System Assessment

The critical issue in software quality is to maintain the relevance of the software to the dynamics requirements and expectations. For the last forty years, many software quality models have been developed that focused on the technical and behavioural aspect of the software and little attention towards user perspective of quality. Our previous works in certification exercises have revealed the needs and rational for software certification from user approach. This is aligned with several new developments such as social networking software, various software on the market and development approach as agile methods that leads to user dominance and control over the software. Thus, users are more criticised and demanded in the quality aspects of the software service that accessible to wide range of people from various categories of users. The users of the web-based systems can be defined in several categories with different interests and perspectives but this research only focuses on web users in general. The new structure of quality model is defined. The enhanced quality model and system are valuable to overcome the limitations of previous models and further improve the application in assessment process and software certification

Why HTTPS is not Enough -- A Signature-Based Architecture for Trusted Content on the Social Web

Easy to use, interactive web applications accumulating data from heterogeneous sources represent a recent trend on the World Wide Web, referred to as the Social Web. There however, security standards are often disregarded in favor of interface design or brand new features. This prevents the new services from gaining ground in the enterprise, in medical or e-government environments. We propose the deployment of XML Digital Signatures on web content and demonstrate how an architecture enabling for various security properties would look like. The solution proposed will benefit from the research on security engineering in Service-Oriented Architectures and thus allows for an in-depth analysis on the results

Software Certification Modeling: From Technical to User Centric Approach

Abstract: One of the most essential issues in software products is to maintain it relevancy to the dynamics of the user's needs. Many researches and studies have been carried out in quality aspect of software products to overcome these problems. Several software quality assessment models and metrics have been introduced with strengths and limitations. The current quality models such as McCall, Boehm, ISO9126, Sistemic and PQF model are used as the benchmark for product assessment. In order to enhance the assurance and buoyancy of the software products, certification process and models have been introduced and developed. Previous fundamental and basic software certification models such as SCM-Prod and SPAC were developed to solve the uncertainties in software quality in two views which are the end product and the development process. However, the models are based on specific requirements and have certain limitations. SCM-Prod model focuses on the certification and quality requirements of software products in general. While SPAC model focuses on software certification based on development process approach. Our previous experiences in conducting certification exercises and case studies collaborating with several agencies in Malaysia, the requirements for user based software certification approach is needed and demanded. The emergence of social network applications and other varieties of software in the market has led to the domination of users over the software. As software become more accessible to the public through internet applications, users are becoming more critical in the quality of the services provided by the software. Users should be able to assess and certify their own products within their own environment at anytime and anywhere. The quality attributes for software assessment should be based on user's perspective and view. This new paradigm should the alternative focus in software product quality assessment and certification. This paper presents the evolution of software certification and assessment from technical view to user centric approach. It discusses the concept of user centric approach in software assessment and certification which also focuses on the design and development of the model (ucSoftC), the components and attributes embedded in this model. The development is believed to be beneficial and valuable to overcome the constraints and improve the application of software certification model in future
