Batch Verification of Validity of Bids in Homomorphic E-auction

Bid opening in e-auction is efficient when a homomorphic secret sharing function is employed to seal the bids and homomorphic secret reconstruction is employed to open the bids. However, this high efficiency is based on an assumption: the bids are valid (e.g., within a special range). An undetected invalid bid can compromise correctness and fairness of the auction. Unfortunately, validity verification of the bids is ignored in the auction schemes employing homomorphic secret sharing (called homomorphic auction in this paper). In this paper, an attack against the homomorphic auction in the absence of bid validity check is presented and a necessary bid validity check mechanism is proposed. Then a batch cryptographic technique is introduced and applied to improve the efficiency of bid validity check.

Visitor Relationship Management (VRM) - Repeat Visitation Opportunities for Destination Marketing Organisations

In competitive tourism markets the consumer-traveller is spoilt by choice of available destinations. Successfully differentiating a destination and getting noticed at decision time is arguably the focus of activities by destination marketing organisations (DMOs). In pursuit of differentiation, three emergent themes in the marketing literature during the past decade have been branding, integrated marketing communications (IMC), and customer relationship management (CRM) a fundamental goal of each being stimulating customer loyalty. However there has been little attention given to destination loyalty in the tourism literature. The purpose of this paper is to report an exploratory investigation of visitor relationship management (VRM) by DMOs. Based on interviews with the management of 11 regional tourism organisations (RTO) in Queensland, Australia, the opportunities for, and immediate challenges of, VRM are discussed. While each RTO recognised the potential for VRM, none had yet been able to develop a formal approach to engage in meaningful dialogue with previous visitors from their largest market.

Selecting an IMC Career: Influences, Choices and Destinations

Integrated marketing communication incorporates both customer and non-customer stakeholder groups. While the literature commonly refers to this distinction as marketing communication and corporate communication, respectively, and practitioners accept the need for these roles, this study aims to explore the student perspective. US-based research suggests that students are more interested in marketing communication activities such as promotion that target customer stakeholders, and less interested in corporate communication activities that target non-customer stakeholders including employees, investors, and government (Bowen, 2003). The findings of this study match its US counterpart, and present implications for both the education and practice of marketing communication

Communication Architecture Design for Real-Time Networked Control Systems

Networked control over data networks has received increasing attention in recent years. Among many problems in networked control systems (NCSs) is the need to reduce control latency and jitter and to deal with packet dropouts. This paper introduces our recent progress on a queuing communication architecture for real-time NCS applications, and simple strategies for dealing with packet dropouts. Case studies for a middle-scale process or multiple small-scale processes are presented for TCP/IP based real-time NCSs. Variations of network architecture design are modelled, simulated, and analysed for evaluation of control latency and jitter performance. It is shown that a simple bandwidth upgrade or adding hierarchy does not necessarily bring benefits for performance improvement of control latency and jitter. A co-design of network and control is necessary to maximise the real-time control performance of NCSs

Evolutions of an Online Generation: Education, Industry and IMC

This paper traces the evolutions of a new generation of students who are predominantly the ‘online generation’; explores the emerging impact of this generation on industry; identifies the changing role of education from traditional classroom to an online environment; and explores the contribution related to integrated marketing communications (IMC). Educational requirements from a business perspective must incorporate global business demands; virtual learning environments progress the online generation towards a post-modern learning state. The central proposition of this paper is that the emergence of IMC in evolving industry practices is influenced by student generations who are producing a new paradigm of alignment between education and industry. This is purely a conceptual exploration using limited examples to provide some context and illustrate the questions raised for consideration.
