BOB BLAKLEY is chief scientist for security and privacy at IBM Tivoli Software. He was the general chair of the 2003 IEEE Security and Privacy Conference and served as general chair of the Association for Computing Machinery’s (ACM’s) New Security Paradigms Workshop. Dr. Blakley was a member of CSTB’s committee that produced the report Who Goes There? Authentication Through the Lens of Privacy (2003). He was named Distinguished Security Practitioner by the 2002 ACM Computer Security and Applications Conference (ACSAC) and serves on the editorial board of the International Journal of Information Security (IJIS). He was the editor of the Object Management Group’s (OMG’s) CORBA security specification and is the author of CORBA Security: An Introduction to Safe Computing with Objects. Dr. Blakley was also the editor of the Open Group’s Authorization API specification and the OASIS Security Services Technical Committee’s SAML specification effort. He has been involved in cryptography and data security design work since 1979 and has authored or coauthored seven papers on cryptography, secret-sharing schemes, access control, and other aspects of computer security. He holds nine patents on security-related technologies. Dr. Blakley received an A.B. in classics from Princeton University and a master’s degree and Ph.D. in computer and communications sciences from the University of Michigan.
JEANETTE BLOMBERG manages the Work in Organizational Context (WORC) group at the IBM Almaden Research Center. She joined IBM Research in 2002 to help establish Service Research, a group focused on providing research in support of IBM’s Global Services division. Her research focuses on the interplay between people, technology, and organizational practices. Dr. Blomberg is also an industry-affiliated Professor of Human Work Science at the Blekinge Institute of Technology in Sweden, where she advises Ph.D. students and organizes a biennial Ph.D. course on work practice and design for students throughout the Nordic countries. Prior to assuming her current position at IBM, Dr. Blomberg was director of Experience Modeling Research at Sapient Corporation, where she helped establish the Experience Modeling practice and managed Sapient’s San Francisco Experience Modeling group. While at Sapient she directed and participated in research projects for global technology, energy, automotive, transportation, consumer products, and financial services companies. Dr. Blomberg was also a founding member of the pioneering Work Practice and Technology group at the Xerox Palo Alto Research Center (PARC). Over the years her research has explored issues in social aspects of technology production and use, ethnographically informed organizational interventions, participatory design, case-based prototyping, and workplace studies. She received her Ph.D. in anthropology from the University of California, Davis, where she taught courses in cultural anthropology and sociolinguistics.
JOSEPH P. CAMPBELL received B.S., M.S., and Ph.D. degrees in electrical engineering from Rensselaer Polytechnic Institute in 1979, the Johns Hopkins University in 1986, and Oklahoma State University in 1992, respectively. Dr. Campbell is currently a senior member of the technical staff at the MIT Lincoln Laboratory in the Information Systems Technology Group, where he conducts speech-processing research and specializes in advanced speaker recognition methods. His current foci are high-level features for and forensic-style applications of speaker recognition, creating corpora to support speech-processing research and evaluation, robust speech coding, biometrics, and cognitive radio. Before joining Lincoln, he served 22 years at the National Security Agency (NSA). From 1979 to 1990, Dr. Campbell was a member of NSA’s Narrowband Secure Voice Technology research group. He and his teammates developed the first DSP-chip software modem and LPC-10e, which enhanced the Federal Standard 1015 voice coder and improved U.S. and NATO secure voice systems. He was the principal investigator and led the U.S. government’s speech coding team in developing the CELP voice coder, which became Federal Standard 1016 and is the foundation of digital cellular and voice-over-the-Internet telephony systems. From 1991 to 1998, Dr. Campbell was a senior
