  • Patent number: 11392837
    Abstract: Embodiments provide for automated dynamic data quality assessment. A data quality job including a new data sample is received. If the new data sample is determined to be added to a reservoir of data samples, a quality verification request is sent to an oracle. A new data sample quality estimate is received from the oracle. The new data sample and estimate can be added to the reservoir. A judgment associated with a new data sample is received from a predictive model. Whether to send a new data sample quality verification request to an oracle is determined. If a new data sample quality estimate is received from the oracle, whether to add the new data sample and the judgment to the reservoir is determined.

  • Publication number: 20220100475
    Abstract: The disclosure relates to systems, methods and devices to provide race-condition true random number generator (TRNG) for soft intellectual property (IP) in field-programmable gate arrays (FPGAs). In an exemplary embodiment, a pair of long adder chains are raced against one another to complete a full cycle. Due to variances in the silicon, different chains will win each race at different times and thereby produce entropy. A calibration circuit can be used to set up the adder chains in an appropriate initial state to maximize the entropy produced. This structure has been found to be robust to layout changes, and the use of two such adder-chain-pairs reduces interference from other structures. Among others, the soft IP makes adding a robust TRNG to an FPGA much easier without concerns for how the structures are laid out or what other IP is nearby in the layout. The disclosed embodiments reduces the effort to add a TRNG to an FPGA design and improves the robustness of the TRNG making the design FIPS certifiable.

  • Patent number: 11250051
    Abstract: An approach is provided for predicting a pose error for a sensor system based on a trained machine learning model. The approach, for example, involves receiving images depicting a survey point with a known physical location. The approach also involves determining meta-data associated with the sensor system used to capture the images. The approach further involves generating a ray from the capture location through a pixel location of the survey point on an image plane of each image. The approach further involves calculating an error between the ray generated for the image and the known physical location. The approach further involves training a machine learning model to predict a pose error from image data captured using the sensor system based on the error in combination with features extracted from the image and the meta-data for the image. The approach further involves providing the trained machined learning as an output.

  • Publication number: 20210398909
    Abstract: Techniques and mechanisms for providing physically unclonable function (PUF) circuitry at a substrate which supports coupling to an integrated circuit (IC) chip. In an embodiment, the substrate comprises an array of electrodes which extend in a level of metallization at a side of the insulator layer. A cap layer, disposed on the array, is in contact with the electrodes and with a portion of the insulator layer which is between the electrodes. A material of the cap layer has a different composition or microstructure than the metallization. Regions of the cap layer variously provide respective impedances each between a corresponding two electrodes. In other embodiments, the substrate includes (or couples to) integrated circuitry that is operable to determine security information based on the detection of one or more such impedances.
