Stuart Haber is a researcher at Hewlett-Packard Laboratories. Along with Scott Stornetta, he was a co-founder of Surety, Inc., which was spun off by Bellcore in 1993 to commercialize the secure digital time-stamping technology that the two of them developed as researchers at Bellcore (now Telcordia Technologies). In addition to Bellcore and Surety, he has also worked as a researcher in STAR Laboratory, the research arm of InterTrust Technologies, which provides digital rights management systems. Dr. Haber received his B.A. from Harvard University and his M.S. from Stanford University, both in mathematics, and his Ph.D. in computer science from Columbia University in 1988. He has lectured and published scientific articles on several practical and theoretical aspects of cryptology, on the theory of computing, and in electrical engineering.
