When a system receives sensitive data, it can request an encryption key from an encryption/decryption unit. A central processing unit (CPU) of the system can encrypt the sensitive data using the encryption key before writing the sensitive data to memory. Thus, the sensitive data is encrypted when written to memory.

The invention includes a tool for the generation and usage of a dynamic polychrome lattice image for unique and secure authentication and verification purposes. The tool is multi-purposed and can be applied to a variety of use cases and may utilize multiple channels of communication between devices. The dynamic polychrome lattice image may be adjusted according to the display size and resolution of various user devices. System devices may scan the dynamic polychrome lattice image, and upon successful retrieval and decryption of the dynamic polychrome lattice image, the user may be authenticated and verified to access one or more programs or services.

Techniques for supporting invocations of the RDTSC (Read Time-Stamp Counter) instruction, or equivalents thereof, by guest program code running within a virtual machine (VM), including guest program code running within a secure hardware enclave of the VM, are provided. In one set of embodiments, a hypervisor can activate time virtualization heuristics for the VM, where the time virtualization heuristics cause accelerated delivery of system clock timer interrupts to a guest operating system (OS) of the VM. The hypervisor can further determine a scaling factor to be applied to timestamps generated by one or more physical CPUs, where the timestamps are generated in response to invocations of a CPU instruction made by guest program code running within the VM, and where the scaling factor is based on the activated time virtualization heuristics. The hypervisor can then program the scaling factor into the one or more physical CPUs.

The disclosure relates to a method for enabling the secure functions of a chipset (1) and especially the encryption of the content of the secure memory (7) when the device goes into low power mode. The content of the secure memory (7) may be encrypted and stored in an external memory (20) during low power mode of the chipset (1).

Techniques for providing a secure clock source in a communication network are disclosed. For example, a method comprises participating in a bi-directional authentication with a network entity in a communication network, sending a clock service request message to the network entity, receiving a clock service accept message in response to the clock service request message when the apparatus is eligible to use a clock service, and receiving one or more secure clock signals from the network entity. Another method comprises participating in a bi-directional authentication with a requesting device in a communication network, receiving a clock service request message from the requesting device, verifying the eligibility of the requesting device to request a clock service, and sending one or more secure clock signals to the requesting device in response to successfully verifying the requesting device.

A computerized system and method may include, in response to receiving a blockchain via a communications network that includes information associated with an event, parsing, by a blockchain parsing engine being executed by a blockchain node, the information to identify a status state of an item related to the event. The blockchain may be inclusive of the information along with the status state of the item may be stored in a storage unit. An event tracking engine may determine from the parsed information that the status state of the item transitioned from a first state to a second state. Responsive to the event tracking engine determining that a qualifying state is satisfied by the item being in the second state, automatically executing, by the blockchain node, a smart code inclusive of initiating communications between a first party and a second party.

One or more embodiments of the present disclosure relate to monitoring execution of runnables that may be executed by a computing system, the executing begin based at least on a schedule. The monitoring may include one or more of: monitoring timing of execution of the runnables, monitoring one or more sequences of execution of the runnables, or monitoring health of at least a portion of the computing system executing the runnables. Additionally or alternatively, one or more embodiments may relate to determining compliance with respect to one or more execution constraints based at least in part on the monitoring.

The present embodiments relate generally to systems and methods for securing operation of an ultrasound scanner for use with a multi-use electronic display device. In some embodiments, the multi-use electronic display device can control whether the ultrasound scanner is permitted to generate ultrasound image data for display based on an institution affiliation status of the ultrasound scanner retrieved from a server. In some embodiments, the multi-use electronic display device can control whether the ultrasound scanner is permitted to generate ultrasound image data for display based on whether a digital certificate provided by a server is successfully validated.

An information processing device includes: a storage that stores determination criterion information indicating a determination criterion for determining whether or not a behavior of an application operating on a device provided to a vehicle is normal; and a detector that obtains behavior information indicating the behavior of the application, and detects an anomaly in the behavior of the application, based on (i) state information that indicates a state of the mobility and is obtained via the mobility network and (ii) the behavior information obtained and the determination criterion information stored in the storage.

The encrypted data analysis device includes a sorting unit that sorts by [Time Information] and then sorts by [User ID] an encrypted data set group including a plurality of encrypted data sets, each of the plurality of encrypted data sets including a [Location ID], the [User ID], and the [Time Information], an encoding unit that generates a [Flow], and encoding the [Location ID] extracted, and an equal sign determination unit that determines whether a [User ID] and another [User ID] adjacent to each other are equal, and when not equal, replaces a corresponding [Flow] with a [predetermined value that represents invalid].
