Latest Patents

Crawford's latest patents focus on performing vector comparison operations in fully homomorphic encryption. In this innovative method, a homomorphic operation is performed on a data set by applying an encrypted operand supplied as ciphertext. The process involves a data set containing 'i' library vectors, each with 'j' coefficients, which undergoes a pivot operation. This operation stores each set of common 'j' coefficients in respective library ciphertexts. A query ciphertext containing a query vector is then subjected to a homomorphic pivot operation to separate its 'j' coefficients into respective pivoted query ciphertexts. This approach allows for a more efficient homomorphic computation between the ciphertexts of the pivoted forms of the query and library vectors, ultimately computing an encrypted set of vector differences between the query vector and each of the library vectors.
