Below in conjunction with specific embodiment specific implementation of the present invention is described in detail:
Embodiment one:
Fig. 1 shows the realization flow of the terminal device encryption method that first embodiment of the invention provides, and details are as follows:
In step S101, after terminal device started, the mainboard that the receives user's input password that powers on arranged request.
In step S102, according to this mainboard password that powers on request is set, arrange and enable flag.
Wherein, whether this enables flag and is used for identifying user and mainboard has been carried out powering on encrypting and arrange, and is effective flag if this enables flag, illustrates that then the user is provided with the mainboard password setting that powers on, otherwise does not arrange.
In specific implementation process, power on after password arranges request when receiving this mainboard, call the interface of BIOS input-output system or embedded controller EC, flag is enabled in setting, simultaneously, show that the password that powers on arranges the interface, for input and the setting that the user carries out password, also can revise the password that this has set.
In step S103, the password of user input and this are enabled flag be stored in the storer.
Wherein, this storer is EEPROM (Electrically Erasable Programmable Read-Only Memory, EEPROM (Electrically Erasable Programmable Read Only Memo)) or EC ROM (Embedded Controller Read-Only Memory).
In specific implementation process, take by this terminal device as example as computing machine, be provided with as the user after the mainboard password of computing machine, then after the user presses the power switch of computing machine, EC will read from EC ROM or EEPROM and enable flag, when this enables flag when effective, judge that then this computing machine enabled the password that powers on, then power on to keyboard, this keyboard of initialization, further wait for that the user inputs password, if the password of user's input is correct, the password that powers on that is stored in the storer that also namely sets in advance with the user is identical, then carry out normal start electrifying timing sequence, start this computing machine, thereby can obtain the data message in this computing machine, otherwise continue to wait for that the user inputs correct password, if user not this password has no idea normally to power at all, even stolen, also can't use computing machine, can only return the again storer of burning storage password of factory.
Need to prove that this password that powers on arranges function for can whether opening for user selection, only when really needing this safety guarantee, just be necessary to open, otherwise the user forgets Password, with the data information that is difficult to check in the computing machine.
In embodiments of the present invention; after starting at terminal device; the mainboard that the receives user's input password that powers on arranges request; according to this mainboard password that powers on request is set; flag is enabled in setting; the password of user input and this are enabled flag to be stored in the storer; realized to the terminal device mainboard power on the level other encryption; solved when utilizing existing encryption method that the data in the terminal device are protected, the low problem of security has improved the security of data in the terminal device; and the present invention just can realize by software program; need not to increase any cost, thereby realized under the prerequisite that does not increase cost, having guaranteed the terminal device security.
Embodiment two:

In step S202, when judging that this enables flag when effective, cipher input equipment is powered on and carry out initialization.
In specific implementation process, when judging that this enables flag when effective, the mainboard encryption that powers on of also namely having judged this computer installation then at first powers on to cipher input equipment, for example, keyboards etc. carry out initialization to this cipher input equipment, otherwise, enable flag when invalid when judging this, also namely judge this computing machine the mainboard encryption that powers on is not set, then carry out normal computer booting electrifying timing sequence this moment, start this computer equipment.
In step S203, receive the user by the password of this cipher input equipment input.
In step S204, if this password is correct, then carry out normal start electrifying timing sequence, otherwise continue to wait for that the user inputs password, until Password Input is correct.
In specific implementation process, take by this terminal device as example as computing machine, when this enables flag when effective, judge that then this computing machine enabled the mainboard password setting that powers on, then at first power on to keyboard, this keyboard of initialization, wait for that further the user inputs password, if the password of user input is correct, the password that powers on that is stored in the storer that also namely sets in advance with the user is identical, then carries out normal start electrifying timing sequence, start this computing machine, thereby can obtain the data message in this computing machine, otherwise continue wait for that the user inputs correct password, if user's this password not, then have no idea normally to power at all, even stolen, also can't use this computing machine, can only return the again storer of burning storage password of factory.
In addition, input in the process of password the user, whether terminal device comes the prompting user Password Input correct with the form of light or sound, for example, inputs in the process of password the user, owing to cannot see the interface when user inputs password, then can use indication lamp for computer to tell whether the user inputs correct, for example, behind the input password, if input is correct, then lamp dodges three times; If input error, lamp are gone out, then Chang Liang waits for that the user re-enters password.
In embodiments of the present invention, power in the process of deciphering terminal device being carried out mainboard, if the password of user input is identical with pre-stored password in storer, then can realize deciphering, otherwise can't start shooting, the security of data is improved in the terminal device.
One of ordinary skill in the art will appreciate that all or part of step that realizes in above-described embodiment method is to come the relevant hardware of instruction to finish by program, described program can be stored in the computer read/write memory medium, described storage medium is such as ROM/RAM, disk, CD etc.
