Security without identification: transaction systems to make Big Brother obsolete

by David Chaum
"... The large-scale automated transaction systems of the near future can be designed to protect the privacy and maintain the security of both individuals and organizations. DAVID CHAUM Computerization is robbing individuals of the ability to monitor and control the ways information about them is used. A ..."

Systems Competition and Network Effects

by Michael L. Katz, Carl Shapiro - JOURNAL OF ECONOMIC PERSPECTIVES—VOLUME 8, NUMBER 2—SPRING 1994—PAGES 93–115 , 1994
"... Many products have little or no value in isolation, but generate value when combined with others. Examples include: nuts and bolts, which together provide fastening services; home audio or video components and programming, which together provide entertainment services; automobiles, repair parts and ..."

"... ABSTRACT Using dealer's quotes and transactions prices on straight industrial bonds, we investigate the determinants of credit spread changes. Variables that should in theory determine credit spread changes have rather limited explanatory power. Further, the residuals from this regression are ..."

Privacy Preserving Association Rule Mining in Vertically Partitioned Data

by Jaideep Vaidya, Chris Clifton - In The Eighth ACM SIGKDD International Conference on Knowledge Discovery and Data Mining , 2002
"... Privacy considerations often constrain data mining projects. This paper addresses the problem of association rule mining where transactions are distributed across sources. Each site holds some attributes of each transaction, and the sites wish to collaborate to identify globally valid association ru ..."

rules. However, the sites must not reveal individual transaction data. We present a two-party algorithm for efficiently discovering frequent itemsets with minimum support levels, without either site revealing individual transaction values.

Mobile Agents: Are They a Good Idea?

by David Chess, Colin Harrison, Aaron Kershenbaum, T. J. Watson , 1995
"... Mobile agents are programs, typically written in a script language, which may be dispatched from a client computer and transported to a remote server computer for execution. Several authors have suggested that mobile agents offer an important new method of performing transactions and information ret ..."

Privacy Preserving Mining of Association Rules

by Alexandre Evfimievski, Ramakrishnan Srikant, Rakesh Agrawal, Johannes Gehrke , 2002
"... We present a framework for mining association rules from transactions consisting of categorical items where the data has been randomized to preserve privacy of individual transactions. While it is feasible to recover association rules and preserve privacy using a straightforward "uniform" ..."

MAFIA: A maximal frequent itemset algorithm for transactional databases

by Doug Burdick, Manuel Calimlim, Johannes Gehrke - In ICDE , 2001
"... We present a new algorithm for mining maximal frequent itemsets from a transactional database. Our algorithm is especially efficient when the itemsets in the database are very long. The search strategy of our algorithm integrates a depth-first traversal of the itemset lattice with effective pruning ..."

Personality and transformational and transactional leadership: A meta-analysis

by Joyce E. Bono, Timothy A. Judge - Journal of Applied Psychology , 2004
"... This study was a meta-analysis of the relationship between personality and ratings of transformational and transactional leadership behaviors. Using the 5-factor model of personality as an organizing framework, the authors accumulated 384 correlations from 26 independent studies. Personality traits ..."

Protecting Privacy when Disclosing Information: k-Anonymity and Its Enforcement through Generalization and Suppression

by Pierangela Samarati, Latanya Sweeney , 1998
"... Today's globally networked society places great demand on the dissemination and sharing of person-specific data. Situations where aggregate statistical information was once the reporting norm now rely heavily on the transfer of microscopically detailed transaction and encounter information. Thi ..."

Limiting Privacy Breaches in Privacy Preserving Data Mining

by Alexandre Evfimievski, Johannes Gehrke, Ramakrishnan Srikant - In PODS , 2003
"... There has been increasing interest in the problem of building accurate data mining models over aggregate data, while protecting privacy at the level of individual records. One approach for this problem is to randomize the values in individual records, and only disclose the randomized values. The mod ..."
