  • Patent number: 12284216
    Abstract: A system and method are provided to facilitate securing windows discretionary access control. During operation, the system determines a Windows domain model including: user-specified desired effective permissions as capability assignments of principals on resources, wherein a respective capability assignment comprises a permission of a respective principal to a respective resource and wherein a respective principal comprises a user or a group of users; and user-specified policies and rules for relationships between principals, groups, and resources. The system creates a domain graph and an access control graph based on the Windows domain model. The domain graph maps paths between nodes representing users, groups, and resources based on the policies and rules. The access control graph allows for calculation of actual permissions of principals on resources based on the desired effective permissions.

  • Patent number: 12267700
    Abstract: Methods and systems to commission building environmental sensors are disclosed. The system includes a device that will move about the environment of a building (inside and/or outside) and detect building environmental sensor devices that are installed in the environment. For each of the sensor devices, in response to detecting the sensor device, the system will retrieve an identifier for the sensor device, and it will determine whether the sensor device is registered with a control system. If the sensor device is registered with the control system, the system will not automatically implement a commissioning process with the sensor device. If the sensor device is not registered with the control system, the system will automatically implement the commissioning process with the sensor device.

  • Publication number: 20250103724
    Abstract: The present disclosure is directed to systems and methods of coordinating threat detection and mitigation among a fleet of trusted devices. As described herein, cybersecurity is a growing concern of many individuals and organizations, especially for those that use multiple electronic devices. In expansive computing environments such as these, security information and event management (SIEM) solutions have been developed. However, providing a holistic solution to a distributed environment remains challenging. According, the systems and methods described utilize an SIEM solution in conjunction with a threat response profile hosted locally on a trusted device within a fleet of trusted devices to provide a coordinated threat response that can be narrowly and/or broadly applied to one or more devices of the fleet of trusted devices.

  • Patent number: 12260351
    Abstract: Methods and systems for automatically predicting the probability of regulatory compliance approval based on data contained in a data structure. A data structure can be configured to include data collated and collected from one or more regulators (e.g., regulatory agencies) and one or more value chain participants. Such data is inclusive of data indicative of actual approval-request results of applications for regulatory approval by one or more regulators and variable weights assigned to different data elements. A prediction can be then made as to the probability that an application for regulatory approval by a value chain participant will be approved by a regulator based on the data collated and collected and contained in the data structure. This approach predicts the probability that an application for regulatory approval by a value chain participant will be approved and also predicts what is missing for a regulatory approval application.

  • Patent number: 12246531
    Abstract: A method of inkjet printer operation produces a security pattern in a printed document. In one embodiment, the security feature is printed in the document as a line target with printheads that have been rotated so the rows of inkjets in the printhead are not aligned in the cross-process direction. The line target in the original document has a frequency response to that differs from a copy formed with a device that does not have rotated printheads. In another embodiment, a sneeze pattern is modified by shifting pixels of at least one color separation in the sneeze pattern in a cross-process direction or a process direction. A copy is identified because it does not contain the shifted pixels.

  • Patent number: 12250354
    Abstract: A method, system and apparatus for rendering a gloss effect on a recording medium, can involve rendering a foreground pattern using a first ink composition comprising infrared absorbing colors, wherein said first ink is lightened with lightening parameters by the addition of paper white holes and rendering a background pattern using a second ink composition comprising a process or spot color, wherein said second ink is darkened with darkening parameters by the addition of infrared absorbing colors that have different amounts of infrared absorbing colors than that of the first ink composition. The lightening parameters and the darkening parameters are adjustable to ensure that the first and second inks appear approximately the same at printed sizes. Anisotropic properties can be introduced to the first and second inks, causing non-uniformity in their reflection of light in different directions when viewed under a light source, thereby creating a gloss effect renderable on a recording medium.
