  • Patent number: 11509672
    Abstract: A system and method of detecting an unauthorized access, phish attempt, or ransomware attempt based on limiting network transmission of data packets within an authorized device range. The method includes establishing a router hop limit value to predetermine an authorized device range for data packets to be exchanged between communicating pair devices and limiting transmission of data packets to within the predetermined authorized device range by discarding data packets after reaching the predetermined authorized device range as a function of the established hop limit value, to exclude devices beyond the predetermined authorized device range. Analyzer, Explorer, Setter, Modifier and Monitor Modules interoperate to suppress spurious communications from remote intruders.

  • Patent number: 11469899
    Abstract: A system and a method for user authentication and/or authorization, including a passive card to encode a first portion of an authentication or authorization code for a user via capacitive points, and a portable computing device with a capacitive screen to encode a second portion of the code. Each capacitive point is connected to an electronic circuit, being activable by physical contact of the user or with an electrical ground. Once the user has requested access to a specific service or operation, and when at least some of the passive points are activated and the passive card is in contact with the capacitive screen, the device reads the capacitive points, decoding the first portion of the code, and cryptographically signs the decoded portion using the second portion, providing the code, which is used as cryptographic key to grant access to the service or operation.

  • Patent number: 11423180
    Abstract: Methods and system are provided for validating the secure assembly and delivery of an IHS (Information Handling System). During factory provisioning of the IHS, an inventory certificate is uploaded to the IHS, where the certificate includes an inventory of the hardware components installed during factory assembly of the IHS and also includes validation schemas the provide instructions for identifying hardware components of the IHS. Upon delivery of the assembled IHS, a validation process is initialized and the inventory certificate is retrieved. Based on the instructions set forth by the validation schemas, the validation process collects an inventory of the detected hardware components of the IHS. The instructions of the validation schemas are further used to compare the collected inventory against the inventory from the signed inventory certificate in order to validate the detected hardware components of the IHS as the same hardware components installed during factory assembly of the IHS.
