Interest in computer privacy
Alongside his research in the fields of fault-tolerant and distributed systems development, Dwork devoted efforts to protecting privacy and privacy. cryptography strong. The mid-80s was a time when concepts like that of the Internet were beginning to appear in the minds of researchers. At the time, the need for privacy for its millions of potential users was emerging as an unforeseen emergency.
Dwork did not miss the opportunity and did various jobs in this area. The first of them came to light when it was published in 1988 under the name "Zero knowledge with finite state verifiers". With this work, Dwork carried out extensive research on the zero knowledge interactive testing systems. This created a further precedent on the capacity of these systems and the security they provide.
Later in 1990, Dwork would present two more papers on strong crypto. The first of them was "Firm Exchange of Verifiable Secrets". With this work, Dwork united his passions: distributed systems, Byzantine fault tolerance and cryptography. It was one of the first works of such magnitude in this regard. Then I would see the light "Perfectly Secure Message Transmission".
The 90s was highly proliferating for Dwork in the crypto field presenting works such as "Non-Malleable Cryptography" (1991). Later that year he would be out "About verification in the secret exchange."
During these years, Dwork would work for greats in the industry like IBM y Microsoft. Of the latter, Dwork is still part of his large group of technology researchers.
A job that would change everything
Dwork and his prolific investigations were very helpful amid the increasing growth of computer technology worldwide. In the midst of the internet and email boom, Dwork did a job with a very specific and useful task: stopping spam. Spam was an annoying practice that companies and individuals used to send large amounts of spam or junk. In times when there were not many filters to control this activity, it was very annoying for those who used email as a regular tool.
However in 1992 Dwork together with Moni Naor published "Charging for processing or fighting against spam". In this work, Dwork and Naor describe a method to stop spam by means of a "work test" It was the first such work aimed at solving the problem of spam. At the time, the idea went completely unnoticed, until 1997 when Adam Back, took the idea of Dwork and Naor and turned it into Hashcash.
With this work from Back, the world of spam would begin to transform and the foundations of something much bigger would begin to be built.
The beginning of the new millennium
The arrival of the new millennium kept Dwork on the job. During the first decade of the new millennium Dwork presents several works among which stand out:
- Non-malleable cryptography (Cynthia Dwork, Danny Dolev, and Moni Naor, 2000)
- Immunizing encryption schemes for decryption errors. (Cynthia Dwork, Moni Naor, Omer Reingold, 2004)
- On the private preservation of histograms. (Shuchi Chawla, Cynthia Dwork, Frank McSherry, Kunal Talwar, 2005)
- Pebbles and Proof of Work. (Cynthia Dwork, Moni Naor, Hoeteck Wee, 2005)
- Differential privacy (2006)
During the second decade of the new millennium, Dwork has been focused primarily on privacy studies. The creation of tools that help maintain it in the digital age we are in. This has earned Dwork wide and deep worldwide recognition in different areas, especially in cryptography and digital privacy.
Recognition of their work
With 158 works signed to date, Dwork has managed to achieve different and varied recognitions for his work, including:
- Charles Ira Young Recognition and Medal for Excellence in Independent Research, Department of Electrical Engineering and Computer Science, Princeton University, 1979.
- Edsger W. Dijkstra Award, 2007
- Member of the American Academy of Arts and Sciences, elected in 2008.
- Member of the National Academy of Engineering, elected in 2008.
- PET Award for Outstanding Research in Privacy Enhancement Technologies, 2009
- Member of the National Academy of Sciences, elected in 2014.

- Member of the American Philosophical Society, elected in 2016.
- Member of the Association of Computing Machinery, elected in 2016.
- Theory of Cryptography Test of Time Award, 2016
Today, Cynthia Dwork is still active as a researcher at both Microsoft and Harvard University, and is also part of the team of researchers at the Alan Turing Institute.
