Embodiment one:
Fig. 1 gives the schema of the data guard method that the present embodiment one provides; the method can be performed by data protecting device; wherein said device can by software and/or hardware implementing; can be used as a part for mobile terminal and it is built in mobile terminal inside, it will be preferred that be built in the operating system of mobile terminal in a software form. As shown in Figure 1, the data guard method that the present embodiment provides comprises the steps:
In step 101, detection setting-up time, user acts at least one unlock command of mobile terminal.
Mobile terminal in the present embodiment can be the equipment such as mobile phone, notebook, PAD intelligent terminal, panel computer.
Described setting-up time can be determined according to the demand of user, such as, setting-up time is 5 minutes, the time opening of described setting-up time can for first unlock command being detected in preset time period time, then at least one unlock command described is unlock command detected in detect that first unlock command start five minutes.
Described unlock command is the instruction that user acts on the unlocking operation of terminal and produces, and described unlocking operation comprises the operation that user inputs unlocking pin or unlock pattern.
Wherein, the unblock number of times that the number that described user acts at least one unlock command of mobile terminal acts on mobile terminal with user is corresponding.
Step 102, when at least one unlock command described meets setting condition, the service voltage of the adjustment adjustable power supply of output voltage, to damage the storage unit of described mobile terminal or to close the access function of the storage unit to mobile terminal, the adjustable power supply of described output voltage is for powering for described storage unit.
The adjustable power supply of described output voltage is the power supply that output voltage can regulate, and it can be built in mobile terminal inside, for described storage unit is powered. At least one unlock command described do not detected, or when at least one unlock command described detected does not meet setting condition, the adjustable power supply of described output voltage is the service voltage that storage unit is provided for normal operation.
The adjustable power supply of described output voltage comprises: low pressure difference linearity voltage stabilizing (LowDropoutRegulator, LDO) power supply and DC/DC conversion (DirectCurrent-DirectCurrent, DC-DC) power supply.
