David Chaum

PROFILE

Widely recognized as the inventor of digital cash, currently David is leading xx network. He is also known for other fundamental innovations in cryptography, including privacy technologies, multiparty computation, and secure voting systems. With a PhDin Computer Science from UC Berkeley, he taught at NYU Graduate School of Business and the University of California, led a number of breakthrough projects as well as founded the International Association for Cryptologic Research, the cryptography group at the Center for Mathematics and Computer Science in Amsterdam, and DigiCash.

XX NETWORK

XX NETWORK

All styles and presecriptions of eyeglasses can be upgraded to overlay, anywhere you can see through them, digital imagery that is of unbeatable quality

Invented, founded and established feasibility of a new paradigm that digitally deconstructs images so when projected by eyewear they reconstruct on the retina with dynamic focus and resolution exceeding the limits of perception.

MULTIPARTY COMPUTATION

The “Turing Machine” of information security, showing how cryptography can solve any information security problem by synthesizing auniversally trustworthy entity

Named the area and led a research effort that proved the fundamental theorems in the three main models and unilaterally in a combined model.

ACHIEVING ELECTRONIC PRIVACY

ACHIEVING ELECTRONIC PRIVACY

Invented what remain the key privacy-technologies—untraceable communication, digital cash, and reputation credentials

Article in Scientific American, and by invitation in technical journals, also predicting in 1992 essentially today’s smartphones and electronic commerce, while offering a solution to the consumer privacy issues of the digital world.

LIQUIFINITY

LIQUIFINITY

Invented, founded and established feasibility of a new paradigm that digitally deconstructs images so when projected by eyewear they reconstruct on the retina with dynamic focus and resolution exceeding the limits of perception.

INTERNATIONAL ASSOCIATION
FOR CRYPTOGRAPHIC RESEARCH

INTERNATIONAL ASSOCIATION

Organized one of the first conference on cryptography and used it to found and launch IACR, at a time when NSA was threatening scientific societies to halt presentation of papers on crypto

It remains the scientific society of the field, sponsoring three conferences each year around the world as well as multiple workshops and a scientific journal.

MIXING

All styles and presecriptions of eyeglasses can be upgraded to overlay, anywhere you can see through them, digital imagery that is of unbeatable quality

Invented, founded and established feasibility of a new paradigm that digitally deconstructs images so when projected by eyewear they reconstruct on the retina with dynamic focus and resolution exceeding the limits of perception.

RANDOM SAMPLE VOTING

RANDOM

Far less expensive, yet more democratic and more secure

Invented and leads an international team developing and proving efficacy of a technology that addresses complexity better than today’s mass elections by letting each voter focus on a single issue at a time—even making feasible the first global election.

ELECTION INTEGRITY TECHNOLOGY

ELECTION

First publicly-verifiable binding governmental election

Invented and led successful implementation and deployment of breakthrough election technology—including software, hardware, special printing and inks—for the municipal elections of Takoma Park Maryland in 2009 and again by invitation in 2011.
