A method of authenticating a user on a mobile device includes gathering samples of behavioral data of the user from multiple sensors of the mobile device, each sensor generating a different number of samples. The method also includes normalizing the samples to have a same number of samples for each sensor. The method further includes extracting, with a convolutional neural network, features from the normalized samples and authenticating the user based on the extracted features.

A multi-host power controller (MHPC) of a flash-memory-based storage device is disclosed. In one aspect, the MHPC receives power mode change requests from each of multiple input/output (I/O) clients. The MHPC extracts and stores a 'vote,' or a requested power mode, from the power mode change requests, and then applies a voting logic to the stored votes to determine whether to transition the flash-memory-based storage device between power modes. If the flash-memory-based storage device is not currently operating in the power mode determined by the MHPC, the MHPC is configured to issue a power mode change command to the flash-memory-based storage device to transition to the determined power mode. In this manner, the MHPC is able to control the power mode of the flash-memory-based storage device while receiving direct power mode change requests from multiple I/O clients.

Command trapping in an input/output virtualization (IOV) host controller (HC) (IOV-HC) of a flash-memory-based storage device is disclosed. In one aspect, an IOV-HC is configured to receive a request from a client register interface (CRI) of one of multiple input/output (I/O) clients. The IOV-HC inspects a content of the request prior to the request being passed to a transport protocol engine. Based on the content, the IOV-HC determines whether the request should be further processed or should be trapped. If the IOV-HC determines that the request should be trapped, the IOV-HC traps the request using a request trap. In some aspects, the IOV-HC generates an interrupt to a virtual machine manager (VMM) to notify the VMM that the request was trapped. In some aspects, the IOV-HC provides a response generation circuit to receive instructions from the VMM to generate a response to the CRI from which the trapped request originated.
