- American Journal of Agricultural Economics
, 1997
"... Conventional tests for food market integration ask often misleadingly, whether prices in different locations move together. This paper develops an alternative methodology, the parity bounds model (PBM), which uses information on transfer costs in addition to food prices to assess the efficiency of s ..."

Food Bytes: Intelligent Systems in the Food Industry
- British Food Journal
, 2002
"... Computers have transformed the design of everything from cars to coffee cups. Now the food industry faces the same revolution, with intelligent computer models being used in the design, production and marketing of food products.

and genetic algorithms, mimic human skills such as the ability to learn from incomplete information, to adapt to changing circumstances, to explain their decisions and to cope with novel situations. These systems are being used to tackle a growing range of problems, from credit card fraud detection and stock
1 Deceptive and Subliminal Food Advertising

to ensure that ads meet certain standards, particularly relating legal and ethical requirements, because consumers do not always have sufficient knowledge to decipher the messages in advertising, to detect the exaggerations or the possible frauds. They, therefore, need to be protected from the incorrect
Risk Detection in E-Commerce Using Markov Decision Process 1
, 2013
"... The growth of e-commerce business especially in the business- to- customer and business- to-business relationships segments in recent years is an indication of how computer technology has improved activities in human lives.

is poised for spectacular growth. An immediate shortcoming of e-commerce is the risk involved in transactions itself. Such risks include viruses, hacking, repudiation, account takeover fraud, card generators, changing ship address, lost and stolen cards, delivery of physical goods, delivery of digital goods
RESEARCH ARTICLE Benford’s Law: Textbook Exercises and
"... Benford’s Law describes the finding that the distribution of leading (or leftmost) digits of innumerable datasets follows a well-defined logarithmic trend, rather than an intuitive unifor-mity. In practice this means that the most common leading digit is 1, with an expected frequency of 30.1%, and t ..."

Cur-rently, the most common application of Benford’s Law is in detecting number invention and tampering such as found in accounting-, tax-, and voter-fraud. We demonstrate that an-swers to end-of-chapter exercises in physics and chemistry textbooks
Funkspiel schemes: an alternative to conventional tamper resistance
- In Proceedings of the 7th ACM conference on Computer and communications security, CCS'00
, 2000
"... Abstract We investigate a simple method of fraud management for secure devices that may serve as an alternative or complement to conventional hardware-based tamper resistance. Under normal operating conditions in our scheme, a secure device includes an authentication code in its communications, e.g ..."

.g., in the digital signatures it issues. This code may be verified by a fraud management center under a pre-determined key σ. When the device detects an attempted break-in, it modifies σ. This results in a change to the authentication codes issued by the device such that the fraud management center can detect

From Commodity to Value: A Privacy Preserving e-Business Architecture
, 2006
"... Privacy has been recognized as a very important issue in electronic commerce. However, many privacy techniques were not adopted and many online anonymity services failed. In this paper we propose treating privacy as a “value ” that is to be added to other services to avoid the adoption pitfall. We p ..."
