Intelligence and Security Informatics: An Information Economics Perspective
An intelligence and security information system must meet the challengeof processing vast volume of information that come from diverse sourceswith distinctive incentives and credibility and providing actionable intelligencebased on the processed information. We focus on solving the problem of analyzingthe incentives and credibility of information sources and propose an informationeconomics perspective to investigate the incentives of the informationproviders in the intelligence and security domain.

Network Effects and Technology Licensing
Information technology innovations that lead to new products/services exhibiting network effects form an increasingly important driver of economic growth. A paramount question faced by such innovators is whether to offer the innovation to other firms that compete with them in the same market. In this paper, we consider a firm’s licensing choice in presence of network effects. The economics literature has found that producer-innovators should use royalties instead of fixed fees when licensing. We find, however, that as the intensity of the network effect increases, the choice of licensing mechanism shifts from a royalty-based regime to a fee-based regime. Furthermore, in each regime, the optimal royalty rate or the optimal fee is influenced by the intensity of the network effect, the investment needed to replicate the innovation, and the size of the potential market. Our results provide valuable insights in formulating licensing decisions in industries that exhibit network effects.

Key Issues for AR-Based Digital Reconstruction of Yuanmingyuan Garden
Yuanmingyuan was called “Garden of All Gardens” before it was looted and burnt down by the Anglo-French allied forces in 1860. Nowadays there are only stone ruins that used to be parts of ancient buildings. The Digital Yuanmingyuan project is designed to provide visitors with the visualization of virtual reconstructions superimposed upon the natural field of the ruins using a personal AR (Augmented Reality) system. It can not only preserve the current appearance of the ruins, but also exhibit the original exquisite architecture of Yuanmingyuan. The technical difficulties of the system are analyzed, and the design of the system hardware and the tracking algorithm are discussed. A prototype of the proposed system is developed and the initial result of restoring one typical scene in Yuanmingyuan is presented.

Introducing abuse frames for analysing security requirements
We are developing an approach using Jackson's Problem Frames to analyse security problems in order to determine security vulnerabilities. We introduce the notion of an anti-requirement as the requirement of a malicious user that can subvert an existing requirement. We incorporate anti-requirements into so-called abuse frames to represent the notion of a security threat imposed by malicious users in a particular problem context. We suggest how abuse frames can provide a means for bounding the scope of security problems in order to analyse security threats and derive security requirements.
