Abstract
Methods, systems, and computer program products for secure distance computations are provided herein. A computer-implemented method includes transforming a set of multiple data points, thereby creating a multiple-dimension representation of the set of data points; storing multiple distinct portions of the multiple-dimension representation of the set of data points across multiple distinct cloud infrastructures; transforming a query point, thereby creating a multiple-dimension representation of the query point; sending multiple distinct portions of the multiple-dimension representation of the query point to the multiple distinct cloud infrastructures; calculating a distance between each of the stored distinct portions of the multiple-dimension representation of the set of data points and each of the sent distinct portions of the multiple-dimension representation of the query point; determining a total distance value by summing the calculated distances; and outputting the total distance value to at least one user.
