  • Publication number: 20240121244
    Abstract: A risk-aware access control system and related methods are provided. In accordance with one aspect of the present disclosure, there is a provided a method of risk-aware access control, comprising: detecting a request to perform an action with respect to two factors, the factors being of a factor type selecting people, devices, documents, and location, wherein the factors are of a different factor type; determining a coupling associated with the requested action based on the factors of the requested action; determining a risk level associated with the coupling; denying the requested action in response to a determination that the risk level does not match a security policy; and allowing the requested action in response to a determination that the risk level matches the security policy.

  • Patent number: 11886563
    Abstract: A continuous authentication system and related methods are provided. The system detects requests to perform user actions. A security value is associated with each user action. The system determines a subsequent session security level in response to an adjustment to a session security level by a security value of a requested user action. The requested user action is permitted and the session security level is adjusted based on the security value of the requested user action in response to a determination by the system that the subsequent session security level is greater than or equal to a threshold session security level. A user authentication challenge is caused (e.g., prompted) in response to a determination by the system that the subsequent session security level is less than the threshold session security level.

  • Publication number: 20230186022
    Abstract: A method at a computing device including mapping, within a corpus of documents having both natural language terms and computer language terms, each term as a natural language term or a computer language term, thereby creating mapped terms; and applying at least one Latent Dirichlet Allocation (LDA) model to the mapped terms to create topics that correlate the natural language terms and computer language terms.

  • Patent number: 11341255
    Abstract: A document management system having context-based access control and related methods are provided. The document management system determines whether to perform user authentication based on derived context-information comprising one or a combination of derived user-context parameters and document-context parameters that provide additional context to document access requests.
