Abstract: Technologies disclosed herein provide a method for receiving at a device from a remote server, a request for state information from a first processor of the device, obtaining the state information from one or more registers of the first processor based on a request structure indicated by a first instruction of a software program executing on the device, and generating a response structure based, at least in part, on the obtained state information. The method further includes using a cryptographic algorithm and a shared key established between the device and the remote server to generate a signature based, at least in part, on the response structure, and communicating the response structure and the signature to the remote server. In more specific embodiments, both the response structure and the request structure each include a same nonce value.

Abstract: Technologies for protecting virtual machine memory of a compute device include a virtual machine (VM) instantiated on the compute device, a virtual machine monitor (VMM) established on the compute device to control operation of the VM, a secured memory, and a memory manager. The memory manager receives a memory access request that includes a virtual linear address (LA) from the VM and performs a translation of the LA to a translated host physical address (HPA) of the compute device using one or more page tables associated with the VM and VMM. The memory manager determines whether a secured translation mapping of LA-to-HPA that corresponds to the LA is locked. If the mapping is locked, the memory manager verifies the translation based on a comparison of the translated HPA to a HPA translated using the secured translation mapping and, if verified, performs the memory access request using the translated HPA.

Abstract: Technologies for transferring offloading or on-loading data or tasks between a processor and a coprocessor include a computing device having a processor and a sensor hub that includes a coprocessor. The coprocessor receives sensor data associated with one or more sensors and detects events associated with the sensor data. The coprocessor determines frequency, resource usage cost, and power state transition cost for the events. In response to an offloaded task request from the processor, the coprocessor determines an aggregate load value based on the frequency, resource usage cost, and power state transition cost, and determines whether to accept the offloaded task request based on the aggregate load value. The aggregate load value may be determined as an exponential moving average. The coprocessor may determine whether to accept the offloaded task request based on a principal component analysis of the events. Other embodiments are described and claimed.

Abstract: Integrated ECG (electrocardiogram) contacts enable opportunistic heart rate monitoring on a handheld electronic device. First and second ECG contacts are integrated into the device to connect, respectively, first and second ECG electrodes to an internal ECG circuit within the device. The ECG electrodes have vertical and horizontal portions that can be separate portions connected to a common contact, or different portions of an ‘L-shaped’ electrode. The ECG electrodes are positioned on opposite sides of the device to enable opportunistic two-hand contact when the device is used in either landscape or portrait orientation. The internal ECG circuit is to detect two-hand contact by the user on the first and second electrodes, and perform ECG monitoring in response to detecting two-hand contact. A mobile device can opportunistically capture heart rate data along with user context and provide alerts if a deviation is detected between heart rate data and user activity.

Abstract: In embodiments, an apparatus to enforce secure display view for trusted transactions may include a first input interface to receive from an application, via a trusted execution environment (TEE), viewport size data and an identifier of a display associated with a secure display of a trusted transaction; and a second input interface to receive from the application, via an untrusted execution environment, an encrypted transaction bitmap associated with the trusted transaction, to be securely displayed on the display; and an enforcement engine coupled to the first input interface and the second input interface, to verify that the size and location of the transaction bitmap are within the viewport to ensure the secure display of the transaction bitmap. In embodiments, after verification of the size and location of the transaction bitmap being within the viewport, the transaction bitmap may be displayed.

Abstract: An electronic device receives depth sensor data that includes depths sensed in multiple zones in the field of view of a depth sensor. The device determines whether a user is in front of the device based on the depth sensor data. If the user is determined to be present, then the device causes a display to enter an operational mode. Otherwise, the device causes the display to enter a standby mode. The device may also determine whether the user's attention is on the device by determining whether the depth sensor data indicates that the user is facing the device. If so, the device causes the display to enter the operational mode. Otherwise, the device causes the display to enter a power saving mode. The device may use a machine learning algorithm to determine whether the depth sensor data indicates that the user is present and/or facing the device.
