Cynthia Dwork (born June 27, 1958) is a famous American computer scientist. She is known for her important work in cryptography (making and breaking codes), distributed computing (computers working together), and making sure computer programs are fair.
Cynthia Dwork helped create something called differential privacy. This is a way to share information from large groups of people without revealing anyone's private details. She also helped invent "proof-of-work", which is a method used to prevent spam and secure digital currencies like bitcoin.
Today, Dwork works at Harvard University. She is a professor there, teaching computer science and doing research.

Cynthia Dwork's Early Life and School
Cynthia Dwork went to Princeton University for her first degree. She graduated in 1979 with honors. She also won an award for her excellent independent research.
Later, she earned her PhD from Cornell University in 1983. Her research there was guided by a well-known computer scientist, John Hopcroft.
Cynthia Dwork's Work and Discoveries
Cynthia Dwork is famous for her research on keeping data private. She found ways to analyze large amounts of information while protecting individual privacy. Her biggest invention in this area is differential privacy, which she developed in the early 2000s.
What is Differential Privacy?
Differential privacy is a strong way to protect your information. It means that when data is shared or analyzed, it's almost impossible to tell if your specific information was included or not. This is usually done by adding tiny bits of "noise" or random data. This noise makes sure that no single person's data can be easily identified. It allows for accurate studies without giving away secrets.
Other Important Contributions
Dwork has also made big contributions to cryptography. This field is all about secure communication and protecting information.
- Non-Malleable Cryptography: In 1991, with her colleagues, she helped create "non-malleable cryptography." This means that if someone tries to change a coded message, they can't make it look like a different valid message.
- Lattice-Based Cryptography: In 1997, she helped create the first "lattice-based" cryptosystem. This is a type of public-key cryptography that is very hard to break. It's considered very secure.
- Proof-of-Work: With another colleague, she came up with the idea of "proof-of-work." This is a technique where a computer has to do a small amount of work (like solving a puzzle). This helps stop spam emails and is a key part of how digital currencies like bitcoin work.
Dwork also worked on distributed computing. This is about how many computers can work together to solve problems. She won the Dijkstra Prize for her early work on systems that can keep working even if parts of them fail.
Awards and Recognitions
Cynthia Dwork has received many important awards for her work. These awards show how much her contributions have helped the world of computer science.
- In 2007, she won the Dijkstra Prize. This award recognized her important early work on how computers can agree on things, even if some parts are faulty.
- In 2008, she became a member of the American Academy of Arts and Sciences and the National Academy of Engineering.
- In 2014, she joined the National Academy of Sciences.
- In 2015, she became a fellow of the Association for Computing Machinery (ACM).
- In 2016, she was honored by the American Philosophical Society.
- In 2016, she received the TCC Test-of-Time Award.
- In 2017, she won the Gödel Prize. Both of these awards were for her groundbreaking paper that introduced differential privacy.
- In 2020, she received the IEEE Richard W. Hamming Medal for her key work in privacy, cryptography, and distributed computing.
- She also won the Knuth Prize in 2020.
- In 2021, she was a co-winner of the ACM Paris Kanellakis Theory and Practice Award for her work on differential privacy.
- In 2022, she received the RSA Award for Excellence in Mathematics.
- Also in 2022, her 1991 paper on "Non-Malleable Cryptography" won a STOC 30-year Test-of-Time award. This means her work from 30 years ago is still very important today.
- In 2025, Cynthia Dwork was awarded the National Medal of Science, one of the highest honors for scientists in the United States.
