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.

The method further includes injecting the at least one element to the web page to execute the first script. The execution of the first script comprises generating a script element comprising one or more secrets. The method further comprises appending the script element to the web page and deleting the script element from the web page.

Abstract: A method at an autonomous vehicle for signaling a refueling attendant, the method including confirming that the autonomous vehicle is proximal to a refueling station; providing a signal to the refueling attendant; waiting for refueling to commence; and if, after a threshold period, refueling has not commenced, repeating the providing the signal.

Abstract: A method and system to signal transmission layers or dedicated reference signal ports to be used in a multiple input multiple output system, the method including providing a downlink control signal containing information for transmission layers or dedicated reference signal ports utilized, the dedicated reference signal ports being associated with the transmission layers; and using the information to demodulate data on each transmission layer.

Abstract: A method of communicating in a secure communication system, comprises the steps of assembling a message at a sender, then determining a security level, and including an indication of the security level in a header of the message. The message is then sent to a recipient.

Abstract: A computer includes a memory and a processor programmed to execute instructions stored in the memory. The instructions include identifying a function in a binary file, assigning one of a plurality of classifications to the function, and determining that the function requires stack cookie protection based at least in part on the classification assigned to the function.

Abstract: A method at an asset tracking device, the method including activating a receiver at the asset tracking device; obtaining an intelligent transportation system message using the receiver; determining a position from the intelligent transportation system message; and reporting the determined position to a remote server.

Abstract: Methods and devices for encoding a point cloud. A bit sequence signaling an occupancy pattern for sub-volumes of a volume is coded using binary entropy coding. Contexts may be based on neighbour configuration and a partial sequence of previously-coded bits of the bit sequence. A determination is made as to whether to apply a context reduction operation and, if so, the operation reduces the number of available contexts. Example context reduction operations include reducing neighbour configurations based on shielding by sub-volumes associated with previously-coded bits, special handling for empty neighbour configurations, and statistics-based context consolidation.
