Dr. Hideto Tomabechi

Adjunct Fellow
CyLab, CMU


Dr. Hideto Tomabechi received his Ph.D in Computational Linguistics from Carnegie Mellon University (CMU) in 1993. Before joining CMU, Dr. Tomabechi was a Fulbright Research Scientist at Yale Graduate School of Computer Science, Yale AI Project and Yale Cognitive Science Program in the mid 1980’s.
He is currently an Adjunct Fellow at CyLab, CMU which is one of the research centers in cyber security and blockchain related researches in US. During his over 30 years of research in the areas of AI, natural language processing, massively parallel computational architecture, and cyber security, he has led number of government research projects in Japan.
In the 90’s, after completion of his Ph.D at CMU, Dr Tomabechi became an Associate Professor at Tokushima University and then joined Justsystem as a VP R&D. Justsystem was a largest software maker in Japan then. At Justsystem, in the mid 90’s, Dr. Tomabechi led the project “Bechi Unit” which may be the world‘s first implementation of cryptocurrency based on Tomabechi Algorithm. Tomabechi Algorithm was a part of his 1993 CMU Ph.D thesis which is a linear time directed (both acyclic and cyclic) graph algorithm which attain pure discrete mathematical monotonicity. Nakamoto style blockchain attains monotonicity by hashing of tree data structures, whereas Tomabechi Algorithm attains monotonicity by discrete mathematical computational model through directed graph algorithms and non-destructive data structures.
After leaving Justsytems, Dr. Tomabechi focused his research areas in government projects. For past several years, Dr. Tomabechi’s main contributions have been in the efforts of leading collaborations between Japan Self Defense Forces (JSDF) and CMU for enhancing the cyber defense capabilities of JSDF. Also, he has been advising number of governments in crypto related policies. He has also been advising private sector institutions around the world including crypto exchanges and ICO companies.
