Title: Joon-woo Lee: Innovator in Homomorphic Encryption

Introduction

Joon-woo Lee is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of homomorphic encryption, a technology that allows computations to be performed on encrypted data without needing to decrypt it first. With a total of 3 patents, Lee's work is paving the way for advancements in secure data processing.

Latest Patents

One of Joon-woo Lee's latest patents is a "Method and device for performing homomorphic permutation." This invention outlines a method by which a server generates a first ciphertext by adding noise to a basic ciphertext. The server then transmits this ciphertext to a client, performs a predetermined operation on the noise, and subsequently receives a second ciphertext from the client. The process allows for the extraction of the basic ciphertext after removing the noise, enabling secure operations on encrypted data.

Another notable patent is for an "Electronic apparatus, control method thereof and server." This invention describes an electronic apparatus that includes a memory storing a composite function of at least two polynomials. The processor within the apparatus performs operations based on a comparison command received for multiple homomorphic ciphertexts, ultimately obtaining a comparison result based on the operation results. This innovation enhances the efficiency of operations on encrypted data.
