A computer implemented method for detecting input gesture events on a touchscreen of an electronic device and for unlocking the electronic device is disclosed. The method may include displaying, while the electronic device is in a locked state, a plurality of guidance lines on the touchscreen of the electronic device, detecting, during an input gesture event, guidance line crossings and calculating a number of guidance line crossings detected during the input gesture event. The method may also include converting a calculated number of detected guidance line crossings into at least one password digit, comparing a sequence of password digits to a stored password in the electronic device and unlocking, in response to comparing the sequence of password digits to the stored password, the electronic device.

Unlocking electronic devices using touchscreen input gestures

An electronic device can be unlocked by displaying, while the electronic device is in a locked state, on a touchscreen of the electronic device, line(s) dividing the touchscreen into input regions. Input gestures are detected on the touchscreen, and one of the input regions is identified as an input region containing the starting point of the input gesture. A base number is retrieved corresponding to the identified input region, and a numerical value of a password digit is calculated by using the base number and a numerical value corresponding to the input gesture. A sequence of thus calculated password digits is compared to a password stored within the electronic device, and the electronic device is unlocked following a match between the series of calculated password digits and the stored password.

One or more snapshots of data stored over a period of time are maintained in a hybrid storage device comprising a magnetic disk and a solid state disk, wherein a selected snapshot stores information that allows recovery of data that is stored in the hybrid storage device at a selected point in time of the period of time. The hybrid storage device receives an input/output (I/O) command from a computational device. A category of a plurality of categories to which the I/O command belongs is determined, wherein the plurality of categories comprise writing to an unused block, writing to a used block, reading from an unused block, and reading from a used block. In response to determining the category to which the I/O command belongs, the I/O command is handled by one of the magnetic disk and the solid state disk based on the determined category.
