Latest Patents

Zeyu Liu holds a patent titled "Large-precision homomorphic comparison using bootstrapping." This patent outlines systems and methods for improving homomorphic encryption. The process involves a processor receiving an encrypted ciphertext, splitting it into smaller digits, and applying a homomorphic floor function. This function clears the least significant bit from the current smaller digit. The method also includes scaling down the encrypted ciphertext using modulus switching, which changes the ciphertext modulus to a new modulus. Furthermore, a bootstrapping procedure is applied for a sign evaluation function to determine the sign of the scaled-down encrypted ciphertext. Finally, the sign is transmitted along with the ciphertext to a server for subsequent use.
