  • Patent number: 11936778
    Abstract: A Data Security Management System using a communications interface configured to receive and transmit one or more portions of Post Quantum Resistant Encrypted data within a network comprising a plurality of endpoints. Using End-to-End (E2E) Post Quantum Resistant encryption techniques to protect the data, the Data Security Management System provides the flexibility for multiple data schemes in a distributive environment such as, but not limited to, Hyperledger. The system uses a Policy Manager to perform the base configuration of the session to be transmitted or received in an encrypted state. This encrypted state comprises Post Quantum Cryptographic algorithm in use for that session, inclusive with associated keys or digital signatures. The Policy Manager is further configured to verify an identity of endpoint by a multifactor cryptographic authentication mechanism or a biometric authentication mechanism to validate a connection to or from an endpoint.

  • Publication number: 20240042281
    Abstract: Various systems and methods that enhance an exercise or other physical activity performed by a user are described. In some embodiments, a classification system communicates with a media hub to receive images and perform various methods for classifying or detecting poses, exercises, and/or movements performed by a user during an activity. In some embodiments, the systems and methods include a movements database (dB) that stores information as entries relating individual movements to data associated with the individual movements. Various systems, including class generation systems and body focus/activity systems, can utilize the movements database when presenting class content to users and/or presenting exercise information (e.g., muscle groups worked or targeted) to the users.

  • Publication number: 20240031365
    Abstract: This disclosure describes techniques for identifying an application (e.g., accessing application) that is attempting to access a resource. In some examples, access may be managed by an authentication service. When an access request is received at the authentication service from an application on a client device, the authentication service may ask the application to communicate with an identification agent on the client device. The identification agent may perform one or more tests to discover the identity of the application. In some cases, the identification agent may send the identity of the application to the authentication service. The authentication service may then allow or deny access by the accessing application to the resource based at least in part on the discovered identity.

  • Patent number: 11857126
    Abstract: A dispenser bottle containing liquid may be mounted to a wall by a mounting assembly including a base and a carriage plate. Amounting bracket may be anchored to the wall and the carriage plate is coupled to the mounting bracket and is spring biased toward an extended configuration relative to the mounting bracket. A release pin maintains the carriage plate and base in a retracted configuration. A collar projects from an upper end of the mounting bracket to capture a neck of the bottle. A projection extends upwardly from the base and into a socket on the bottom of the bottle when seated on the base. The combination of the mating socket and projection at the base and the collar around the neck of the bottle inhibits removal of the bottle from the mounting assembly when in the retracted configuration.
