A survey of signature based methods for financial fraud detection

Fraud detection mechanisms support the successful identification of fraudulent system transactions performed through security flaws within deployed technology frameworks while maintaining optimal levels of service delivery and a minimal numbers of false alarms. Knowledge discovery techniques have been widely applied in fraud detection for data analysis and training of supervised learning algorithms to support the extraction of fraudulent account behaviour within static data sets. Escalating costs associated with fraud however have continued to drive the migration towards increasingly proactive methods of fraud detection, to support the real-time screening of transactional data and detection of ambiguous user behaviour prior to transaction completion. This shift in data processing from post to pre data storage significantly reduces the available time within which to evaluate newly arriving system requests and produce an accurate fraud decision, demanding increasingly robust and intelligent user profiling technologies to support advanced fraud detection. This paper provides a comprehensive survey of existing research into account signatures, an innovative account profiling technology which maintains a statistical representation of normal account usage for rapid recalculation in real-time. Fraud detection architectures, processing models and applications to date are critically examined and evaluated with respect to their proactive capabilities for detection of fraud within streaming financial data. Discussion is also presented on challenges which remain within the proactive profiling of account behaviour and future research directions within the signature domain.

ECOLOGICAL RESTORATION BASED ON A REGIONAL POLYCENTRIC GOVERNANCE MODEL — REGENERATION OF THE KAREZ WATER SYSTEM IN TURPAN REGION

With the population boom and the rapid industrial and agricultural development, regional water demand has exceeded the supply capacity in Turpan. Modern water infrastructure not only made the unique ecosystem formed by the Karez out-of-balance, but also devitalized the oasis civilization and the indigenous cultural landscape associated with the Karez. Taking the Karez system as an example, this article proposes planning and design schemes and roadmaps based on a regional polycentric governance model to explore a new path of public environmental governance which coordinates the interests of all stakeholders. Four strategies are proposed: 1) establishing the water account management system; 2) establishing an ecological agriculture water saving and control mechanism; 3) introducing an agriculture-husbandry-fishery circular development mode; and 4) revitalizing abandoned space. By re-identifying water supply and demand, rebalancing the existing resources and regional development, and encouraging the role of landscape as ecological infrastructure, resilient landscape and sustainable resource utilization could be realized to maximize the public interest.
