Sarah Gardner, VP of external affairs at Thorn, suggests using "homomorphic encryption" - a form of encryption that lets users perform computations on encrypted data, without first decrypting it.

Russell Impagliazzo, a professor of computer science at the University of California, San Diego, said the LLL algorithm has also led to what is known as homomorphic encryption, which allows calculations to be performed on encrypted data without ever decrypting it.

Dr. Impagliazzo said homomorphic encryption could allow you to provide encrypted financial information to a credit bureau, and the credit bureau to, in turn, calculate your credit score without ever learning anything about you.

Scientists first started working on homomorphic encryption in the 1970s, but it stayed pure research until a decade ago.

Even when quantum computers become powerful enough to break modern cryptography, easily cracking typical encryption algorithms, they won’t be able to break homomorphic encryption.
