  • METHOD AND SYSTEM FOR DATA COMMUNICATION WITH DIFFERENTIALLY PRIVATE SET INTERSECTION
    Publication number: 20240135024
    Abstract: Methods, systems, and apparatuses, including computer programs encoded on computer storage media, for data communication with differentially private intersection dataset. On example method includes: determining a plurality of bias parameters based on a parameter for establishing a differential privacy (DP) data protection; determining an intersection dataset based on client data from a client device and server data from the server device; updating the intersection dataset based on the client data and the plurality of bias parameters; and returning the updated intersection data having the DP data protection to the client device.

  • Method of operating a data-processing system for the simulation of the acoustic wave propagation in the transversely isotropic media comprising an hydrocarbon reservoir
    Patent number: 10495768
    Abstract: A computer implemented method including a numerical model of a region of the earth modeling the acoustic behavior of that region. The method implements an acoustic wave propagator allowing the simulation of the propagation of pure P-waves in transversal isotropic media. The propagator can be applied to applications such as seismic forward modeling, reverse time migration and other two-way wave-equation based applications.
