    Abstract: A method for use in determining a status of a mobile electronic device, comprises repeatedly reading information from a debug log stored in a ringbuffer of the mobile electronic device, repeatedly using the information read from the debug log to construct and maintain an event history for the mobile electronic device, and repeatedly determining the status of the mobile electronic device based on the event history. The method may be used for determining a status of a mobile electronic device and, in particular though not exclusively, for use in determining a status of one or more hardware elements of a mobile phone, a smartphone, a tablet and/or a laptop. A system and a computer program for use in determining a status of a mobile electronic device are also disclosed.

    Abstract: A method for erasing data stored from memory of a network device comprises erasing stored data from the memory of the network device and requesting data from the memory of the network device after completion of the data erasure procedure or accessing the memory of the network device after completion of the data erasure procedure. The method further comprises determining the outcome of the data erasure procedure based at least in part on: the results of a comparison between a response received from the network device and an expected response which indicates a successful erasure of the memory of the network device; or a comparison between any contents of the memory of the network device after completion of the data erasure procedure and expected contents of the memory after the data erasure procedure which are indicative of a successful erasure of the memory of the network device.

    Abstract: A method for use in sanitizing a network of non-volatile memory express devices, comprises identifying the configuration of the network of non-volatile memory express devices including identifying one or more controllers of the non-volatile memory express devices; and identifying which portions of non-volatile memory of the non-volatile memory express devices are accessible to which of the identified controllers. The method further comprises performing a data erasure process in relation to at least one portion of the non-volatile memory of at least one of the non-volatile memory express devices based at least in part on the identified configuration of the network.

    Abstract: A method of erasing data from a data storage apparatus comprising a memory, the method comprises writing a known data pattern to a plurality of known memory locations of the data storage apparatus, causing the data storage apparatus to perform a data erasure procedure, reading data stored at the known memory locations after completion of the data erasure procedure, comparing the read data and the data of the known data pattern, and determining a verification result based at least in part on the result of the comparison between the read data and the data of the known data pattern.

    Abstract: According to an aspect, there is provided a method for self-diagnosing a mobile device comprising at least one or more actuators, one or more sensors and a display. The method comprises, first, feeding a pre-defined control signal to a first actuator of the mobile device and measuring, in response to the feeding, a first electric signal using a first sensor of the one or more sensors. Then, the first electric signal is compared to one or more reference signals associated with the first actuator and the pre-defined control signal. If the first electric signal fails to match the one or more reference signals according to one or more pre-defined criteria, a negative diagnosis is indicated to a user of the mobile device using one or more of a display of the mobile device and one or more actuators of the mobile device.

    Abstract: A method for erasing stored data from the memory of the network device and requesting data from the memory after completion of the data erasure procedure or accessing the memory of the network device after completion of the data erasure procedure. The method further comprises determining the outcome of the data erasure procedure based on: the results of a comparison between a response received from the network device in reply to the request for data and an expected response which is indicative of a successful erasure of the memory of the network device; or the results of a comparison between any contents of the memory of the network device after completion of the data erasure procedure and expected contents of the memory of the network device after completion of the data erasure procedure which are indicative of a successful erasure of the memory of the network device.
