THE CREDIBILITY OF CONSUMER REVIEWS ON THREE E-COMMERCE IN INDONESIA: MIXED METHOD APPROACH

Online stores with more than 3000 reviews have made it difficult for consumers to find reviews that can be used as the main source of information to decide on a purchase. This research aims to investigate the credibility of reviews that consumers can be trusted. This research used mixed methods (quantitative and qualitative) through sequential explanation. In this quantitative study, 300 respondents were collected using a voluntary sampling technique, and 900 reviews from three e-commerce sites in Indonesia were selected purposely. The qualitative approach used in-depth interviews with three consumers and a selected seller using a purposive sampling technique. The data was processed by multiple linear regression and descriptive using SPSS 25.0 and Nvivo 12. Research results confirmed that the motivation to read reviews and consumer attitudes toward reviews significantly affect online purchasing decisions, but a third of consumers still rarely provide reviews. Furthermore, based on source credibility, E-WOM quality, and recommendation rating, in the three e-commerce sites, almost half of the reviews studied were hard to be trusted. Based on these findings, this research summarizes the policy implications for consumers and governments and suggests future research

The impact of privacy regulations on the development of electronic commerce in Jordan and the UK

Improvement in information communication technology (ICT) is one of the factors behind growth in economic productivity. A major dimension of this is the use of the Internet in e-commerce, allowing companies to collect, store, and exchange personal information obtained from visitors to their websites. Electronic commerce has many different variants, and is believed by many governments throughout the world to be the engine of economic stability in the future. While electronic commerce has many benefits, there is evidence to suggest privacy concerns are an inhibitor to its adoption in Jordan and the UK. According to Campbell (1997, p.45), privacy in this context can be defined as “the ability of individuals to determine the nature and extent of information about them which is being communicated to others”. The importance of information in e-commerce has increased, because the main success factor for the completion of transactions between businesses and consumers is the companies’ ability to access consumers’ personal details. This conflicts with the consumers’ fear of providing personal information to un-trusted parties, which makes them disinterested in entering contracts via the internet. This research discusses privacy concerns as an inhibitor for electronic commerce by providing a comparison between UK and Jordanian regulations, to establish the impact that these regulations have ameliorating privacy concerns regarding the development of electronic commerce in Jordan and the UK. The interpretive grounded theory approach has allowed the researcher to gain a deep understanding about privacy perceptions of electronic commerce held by the main stakeholders: government, businesses and consumers. Furthermore, through implementing the Straussian grounded theory approach as a data collection and analysis method, two grounded theories have emerged as giving deeper understanding of the situation in Jordan and the UK regarding privacy concerns and how this affects electronic commerce development in both countries.Albalqa Applied University- Jorda

A flexible architecture for privacy-aware trust management

In service-oriented systems a constellation of services cooperate, sharing potentially sensitive information and responsibilities. Cooperation is only possible if the different participants trust each other. As trust may depend on many different factors, in a flexible framework for Trust Management (TM) trust must be computed by combining different types of information. In this paper we describe the TAS3 TM framework which integrates independent TM systems into a single trust decision point. The TM framework supports intricate combinations whilst still remaining easily extensible. It also provides a unified trust evaluation interface to the (authorization framework of the) services. We demonstrate the flexibility of the approach by integrating three distinct TM paradigms: reputation-based TM, credential-based TM, and Key Performance Indicator TM. Finally, we discuss privacy concerns in TM systems and the directions to be taken for the definition of a privacy-friendly TM architecture.\u

An optimistic fair e-commerce protocol for large e-goods

Suppose two entities that do not trust each other want to exchange some arbitrary data over a public channel. A fair exchange protocol ensures that both parties get what they want or neither gets anything. In this paper, a fair e-commerce protocol for large e-goods is proposed and implemented. The proposed protocol provides a method for the fair exchange of e-money for e-products, and a method for verifying the contents of the exchanged items. The protocol is optimistic and efficient such that when none of the parties tries to cheat, only three messages are sufficient. In case of disputes, three more messages are needed. Furthermore, the customer remains anonymous after the transaction; thus, no information about the customers' shopping habits can be gathered through the protocol. The implementation results show that the protocol is efficient and secure and that only a small number of cryptographic operations is sufficient

PKI Interoperability: Still an Issue? A Solution in the X. 509 Realm

There exist many obstacles that slow the global adoption of public key infrastructure (PKI) technology. The PKI interoperability problem, being poorly understood, is one of the most confusing. In this paper, we clarify the PKI interoperability issue by exploring both the juridical and technical domains. We demonstrate the origin of the PKI interoperability problem by determining its root causes, the latter being legal, organizational and technical differences between countries, which mean that relying parties have no one to rely on. We explain how difficult it is to harmonize them. Finally, we propose to handle the interoperability problem from the trust management point of view, by introducing the role of a trust broker which is in charge of helping relying parties make informed decisions about X.509 certificates
