There is a need to understand how to: spread product information to maximum range, identifying influential users, and analyze how they are intrinsically connected in a social network. In this paper, we collected tweets of Huawei Mate 9 to analyze users’ information behavior such as tweeting, forwarding, and commenting on tweets. We applied independent cascade model to this empirical Twitter diffusion network, and found it is proper to fit to the product information diffusion process. Using its network structure and PageRank measurement, we can identify influential nodes, and interpret the intrinsic connection between these influential nodes. Further, it is significant to consider the node’s background, such as interest, occupation, and country when identifying influential nodes. And it is discussed that the tweet content related to novel technology may attract more participation in ordinary users.

In an e-commerce transaction both the user and the provider of the service have expectations regarding the security of the transaction. These are authentication of those involved in the communication; confidentiality of the information exchanged in the communication; and integrity of the information exchanged in the communication. A secure communication channel will meet these expectations. This chapter provides an understanding of how the Secure Sockets Layer Protocol (SSL) and its variation Transport Layer Security Protocol (TLS) can be used to set up, maintain, and use a secure channel. This secure channel may be used for e-commerce as well as secure communication. In addition, a discussion of SSL's strengths and weakness is presented and alternatives are suggested. Keywords: authentication; confidentiality; IPsec; secure channel; transport layer security protocol (TLS)

Competitive intelligence (CI) is the selection, collection, interpretation and distribution of publicly held information that is strategically important to a firm. A substantial amount of this public information is accessible via the World Wide Web. This paper describes some of the difficulties in using this information resource for CI purposes, some of the solutions to these difficulties, and areas in need of research if the Web is to be used in CI.

The physical transport methods used in wireless communication differ from wired communication. These differences affect how a secure channel can be established in a wireless environment. The purpose of this tutorial is to provide an overview of how a secure channel is set up in a wireless environment that uses the 802.11 or WAP standards.

This paper is a summary of the tutorial on Internet privacy. The objective of the tutorial is to inform users of the Internet how and why their use of the Internet can be monitored. The focus of the tutorial will be Internet privacy at home and in the work place. The tutorial has three major sections: Technical Background, At Home and At Work. The At Home section is concerned with personal privacy infringement. This section will detail who would be interested in personal privacy infringement, how they would accomplish it, and for what purpose. This portion presents topics such as cookies and their uses and log files. In addition the At Home section discusses techniques to avoid privacy infringement (e.g. anonymizers, cookie cutter). The At Work section is concerned with employee surveillance. The topics discussed include who would be interested in this surveillance, how this surveillance would be done and for what purpose. The At Work section also discusses the concept of Acceptable Use Policies (AUP). Questions address: What purpose do AUP serve? How do AUP support or detract from employee surveillance? Both sections require a bit of technical expertise to understand how Internet activity can be monitored. The Technical Background section reviews the client/server paradigm of web computing, the important details of the Hypertext Transfer Protocol (HTTP), and presents an overview of Uniform Resource Locators (URLs). These concepts are necessary to understand how Internet activity con be monitored.

This tutorial presents an overview of the major categories of Web site attacks, their effects, and possible countermeasures. The focus is the Web security necessary for a reasonable guarantee of secure e-commerce. The tutorial is intended for those who have little or no knowledge of Web security and its importance to e-commerce. It provides a basic understanding of the issues, the techniques, and the nomenclature used. An annotated bibliography points the reader to additional sources on specific topics.
