This Obscure Maths Will Revolutionize Data Privacy
Summary
TLDRThe video script discusses the potential of fully homomorphic encryption (FHE) in the context of big data and AI, highlighting its ability to enable data analysis without compromising privacy. FHE allows computations on encrypted data, with results that can only be decrypted by the data owner. Despite its theoretical existence since the 1970s, the technology is computationally intensive and has been slow to adopt. Recent developments include specialized chips from companies like Intel, Chain Reaction, and Fabric Cryptography, aiming to make FHE more practical for applications such as secure health data analysis and scientific research, potentially revolutionizing how sensitive data is handled in the face of stringent privacy regulations.

Q & A
What is the main obstacle in harnessing the full potential of artificial intelligence due to big data?
-The main obstacle is privacy concerns, as using AI to analyze personal data like health records could save lives but requires sharing extremely personal information.
How does new encryption technology address the privacy issue in AI data analysis?
-New encryption technology, specifically fully homomorphic encryption, allows for computations on fully encrypted data and returns an encrypted result that only the data owner can decrypt, thus preserving privacy.
What is fully homomorphic encryption and how does it relate to homomorphisms in mathematics?
-Fully homomorphic encryption is a type of encryption that allows computations on encrypted data. It is related to homomorphisms, which are mathematical operations that preserve the relations of the structures they act upon.
Who is Craig Gentry and what is his contribution to the field of homomorphic encryption?
-Craig Gentry is an American computer scientist who proved the possibility of fully homomorphic encryption and developed an encryption scheme in 2009.
Why hasn't fully homomorphic encryption been widely adopted yet?
-It hasn't been widely adopted because the computational process is extremely expensive, slow, and energy-intensive due to the use of lattice cryptography and the production of very long strings.
What are some companies and institutions working on specialized chips for homomorphic encryption?
-Companies like Intel, working with DARPA, the Korean Electronics and Telecommunications Research Institute, and startups such as Chain Reaction and Fabric Cryptography are developing specialized chips for this purpose.
