  • System and method for performing homomorphic aggregation over encrypted data
    Patent number: 11251936
    Abstract: A system and method for converting an input dataset based on a query received via a user interface into one or more defined range values is provided wherein the input dataset is converted into one or more defined range values based on a conversion value matrix. The present invention provides for encrypting the defined range values of the input dataset into a first cipher text matrix. Further, the present invention provides for encrypting the conversion value matrix into second cipher text matrix. The present invention provides for performing a computation operation between the first cipher text matrix and the second cipher text matrix to generate an aggregated cipher text matrix. The present invention provides for decrypting the aggregated cipher text matrix into a decrypted result matrix. The present invention provides for performing an aggregation operation by counting pre-defined digit in each column of the decrypted result matrix.
