Patent number: 10503911Abstract: Generating an attack graph to protect sensitive data objects from attack is provided. The attack graph that includes nodes representing components in a set of components of a regulated service and edges between nodes representing relationships between related components in the set of components is generated based on vulnerability and risk metrics corresponding to each component. A risk score is calculated for each component represented by a node in the attack graph based on sensitivity rank and criticality rank corresponding to each respective component. Risk scores are aggregated for each component along each edge path connecting a node of a particular component to a node of a related component. In response to determining that an aggregated risk score of a component is greater than or equal to a risk threshold, an action is performed to mitigate a risk to sensitive data corresponding to the component posed by an attack.Type: GrantFiled: July 20, 2018Date of Patent: December 10, 2019Assignee: International Business Machines CorporationInventors: Suresh N.

Patent number: 10503999Abstract: Described is a system for detecting salient objects in images. During operation, the system maps an input image into a frequency domain having a spectral magnitude. The spectral magnitude is replaced with weights from a weight matrix W. The frequency domain is then transformed with the weights to a saliency map in the image domain, the saliency map having pixels with pixel values. A squaring operation is then performed on the saliency map by squaring the pixel values to generate a pixel-value altered saliency map. A final saliency map is generated by filtering the pixel-value altered saliency map. A number of devices may then be operated based on the saliency map.Type: GrantFiled: April 5, 2018Date of Patent: December 10, 2019Assignee: HRL Laboratories, LLCInventors: Shankar R. Rao, Andras Horvath

Patent number: 10482265Abstract: Log(s) of IT events are accessed in a distributed system that includes a distributed application. The distributed system includes multiple data objects. The distributed application uses, processes, or otherwise accesses one or more of data objects. The IT events concern the distributed application and concern accesses by the distributed application to the data object(s). The IT events are correlated with a selected set of the data objects. Risks are estimated to the selected set of data objects based on the information technology events. Estimating risks uses at least ranks of compliance rules as these rules apply to the data objects in the system, and vulnerability scores of systems corresponding to the set of data objects and information technology events. Information is output that allows a user to determine the estimated risks for the selected set of data objects. Techniques for determining ranks of compliance rules are also disclosed.Type: GrantFiled: December 30, 2015Date of Patent: November 19, 2019Assignee: International Business Machines CorporationInventors: Suresh N.

Patent number: 10484043Abstract: Described is a system for adaptive blind source separation. A time-series of data points from one or more mixtures of source signals is continuously passed through adaptable filters, where each filter has a corresponding output signal. An error of each output signal is determined, and a filter state of each filter is determined using the error signals. A set of filter center frequencies are adapted using the set of error signals and the filter states, resulting in new filter center frequencies. The set of filter center frequencies are updated with the new filter center frequencies. Finally, separated source signals are extracted from the mixture of signals.Type: GrantFiled: March 7, 2017Date of Patent: November 19, 2019Assignee: HRL Laboratories, LLCInventors: Charles E.

Patent number: 10462365Abstract: A system and method for low power surveillance. The system receives a series of frames from a camera, each frame having a background and a foreground. A background template is generated. Thereafter, the system receives a new image frame of the scene, the new image frame having a background and a foreground. Potential regions of interest (ROI) are detected in the new image frame. Initial region descriptors are determined in the potential ROI in the foreground. The initial region descriptors are segmented to generate a segmented region. Region descriptors are re-determined from the segmented region. A contiguous sparse foreground is determined from the re-determined region descriptors, the contiguous sparse foreground being a contiguous ROI. The ROI is reconstructed using foveated compressive sensing to generate an image of an interesting object. Finally, the interesting object image is combined with the background template to reconstruct the foreground.Type: GrantFiled: August 6, 2014Date of Patent: October 29, 2019Assignee: HRL Laboratories, LLCInventors: Matthew S Keegan, Kang-Yu Ni, Shankar R.

Patent number: 10404299Abstract: Described is a cognitive signal processor (CSP) for signal denoising. In operation, the CSP receives a noisy signal as a time-series of data points from a mixture of both noise and one or more desired waveform signals. The noisy signal is linearly mapped to reservoir states of a dynamical reservoir. A high-dimensional state-space representation is then generated of the noisy signal by combining the noisy signal with the reservoir states. A delay-embedded state signal is generated from the reservoir states. The reservoir states are denoised by removing noise from each reservoir state signal, resulting in a real-time denoised spectrogram of the noisy signal. A denoised waveform signal is generated combining the denoised reservoir states. Additionally, the signal denoising process is implemented in software or digital hardware by converting the state-space representation of the dynamical reservoir to a system of delay difference equations and then applying a linear basis approximation.Type: GrantFiled: March 2, 2018Date of Patent: September 3, 2019Assignee: HRL Laboratories, LLCInventors: Peter Petre, Bryan H.

Publication number: 20190258888Abstract: Described is a system for bounding box generation. The system operates on an image comprised of pixels having a one-bit value per pixel. Bounding boxes are generated around connected components in the image, the connected components having pixel coordinate and pixel count information. A ranking score is generated for each bounding box based on the pixel coordinate and pixel count information. The bounding boxes are filtered to remove bounding boxes that exceed a predetermined size and pixel count based on the pixel coordinate and pixel count information. The bounding boxes are further filtered to remove bounding boxes that fall below a predetermined ranking score, resulting in remaining bounding boxes. Finally, a device can be controlled or otherwise operated based on the remaining bounding boxes.Type: ApplicationFiled: February 14, 2019Publication date: August 22, 2019Inventors: Austin F.
