  • Patent number: 11386216
    Abstract: Embodiments relate to a system, program product, and method for use with a computer platform to support privacy preservation. The platform measures and verifies data privacy provided by a shared resource service provider. An assessment is utilized to support the privacy preservation with respect to a data steward, and associated shared data. It is understood that data associated with a data service has an expected level of privacy. A privacy score directly correlating to a leakage indicator of the service is formed, and an associated data container is populated with inferred entities deemed to at least meet a preferred privacy level. The privacy score effectively certifies the security of the populated data container.

  • Publication number: 20220180600
    Abstract: The disclosure relates to a 3D reconstruction method based on an on-site edge-cloud collaboration for a cultivated land. An edge-cloud collaborative computing architecture is used, such that the edge computing device performs advance calculations after image data is acquired. The edge computing device measures performances of itself and a cloud data center, and arranges and deploys multiple 3D reconstruction containers in the cloud data center for the 3D reconstruction. Multiple reconstruction containers in the cloud data center perform reconstruction tasks in parallel to quickly obtain 3D reconstruction results, and provide them to the edge computing device for retrieval and download. This method is mainly oriented to agricultural project monitoring scenes, to reduce reconstruction time and a data transmission amount of 3D models, in order to improve a response speed and a quality of 3D reconstruction results, for large-scale on-site monitoring, acceptance, and review purposes of agricultural projects.

  • Publication number: 20220170999
    Abstract: A method and device for compensating for an influence of a magnetic interference source on a measurement of a magnetic field sensor in a device. In the method, a magnetic flux density M1 measured with the magnetic field sensor at a measured ambient temperature Tk is compensated for with a compensation factor Minterference of the magnetic interference source according to M=M1?Minterference, where Minterference=M0+aM0(T?k?T0) and M0 is a magnetic reference flux density relative to a reference temperature T0, a corresponding to a material parameter, which is defined for a used magnet material of the magnetic interference source, and the measured ambient temperature Tk being corrected using a non-linear delay parameter to a temperature of the magnetic interference source T?k. The method is used for the axis-based compensation of a temperature drift, the material parameter a being determined individually for each Cartesian axis.
