Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Be the problem that the data in the External memory equipment that solves the prior art portable terminal are easily revealed or are stolen, the embodiment of the invention provides a kind of data guard method and device of portable terminal.
As shown in Figure 1, the data guard method of the portable terminal that the embodiment of the invention provides comprises:
Step 101 is protected the data in the External memory equipment of portable terminal if desired, obtains the data confidentiality indication information.
In the present embodiment, the described External memory equipment of step 101 can comprise expansion card such as SD card (Secure Digital), CF card (Compact Flash), mmc card (MultiMediaCard) and memory stick (Memory Stick) etc., does not give unnecessary details one by one at this.
Step 102 according to the data confidentiality indication information, is transferred to the data that need protection in the External memory equipment in the built-in memory block of portable terminal.
Step 103, the data that need protection in the built-in memory block are transferred in protection.
In the present embodiment, step 103 pair is transferred to the process that the data that need protection in the built-in memory block are protected, can comprise: the password of the partition holding of storage inside routing information description is set, and wherein, partition holding is in the built-in memory block of portable terminal; Perhaps hide the partition holding that the storage inside routing information is described.
In the present embodiment, the data of transferring in the built-in memory block that need protection are protected, can be comprised multiple mode, do not give unnecessary details one by one at this.
In the present embodiment, the user can be saved in data in the built-in memory block of portable terminal, can also be saved in the External memory equipment of portable terminal.If the data that need protection are arranged in the External memory equipment of portable terminal, the system of portable terminal can obtain the data confidentiality indication information; According to the data confidentiality indication information; the system of portable terminal can transfer to the data that need protection in the External memory equipment in the built-in memory block of portable terminal; and the data of transferring in the built-in memory block are protected, can realize the protection of data in the External memory equipment of portable terminal.
The data guard method of the portable terminal that present embodiment provides; by the data that need protection in the External memory equipment being transferred in the built-in memory block of portable terminal; and the data in the built-in memory block of transferring to portable terminal are protected; can realize the protection of the data in the External memory equipment of portable terminal, improve security and the privacy of data in the External memory equipment of portable terminal.The embodiment of the invention has solved in the prior art, because the External memory equipment of portable terminal is easily extracted the problem that causes data to be revealed or be stolen from portable terminal by other people.
In order to make those skilled in the art can implement the data guard method of the portable terminal that the embodiment of the invention provides; in another embodiment of the present invention; the data guard method of the portable terminal that the embodiment of the invention is provided is done further restriction, and as shown in Figure 2, concrete steps can comprise:
In the present embodiment, the user can be saved in data in the built-in memory block of portable terminal, can also be saved in the External memory equipment of portable terminal.
In the present embodiment, step 201 can arrange the data protection platform at portable terminal, when making the user externally the data that need protection be arranged in the memory device, obtains the data protection authority.If can obtain the data protection authority, can carry out follow-up data protection operation.
In the present embodiment, judge whether the data that need protection are arranged in the External memory equipment, the exterior storage routing information that the system that can use system's autoscan of portable terminal to obtain portable terminal is given tacit consent to judges under the path of exterior storage information correspondence of acquiescence whether the data that need protection are arranged; Perhaps the system of portable terminal directly gets access to the exterior storage routing information that the user defines in the system of portable terminal, under the path of the exterior storage routing information correspondence of judgement definition whether the data that need protection is arranged.
In the present embodiment, after use data protection platform obtains the data protection authority, carry out the data protection of External memory equipment, obtain the data confidentiality indication information.User initiatively triggering mobile terminals obtains the data confidentiality indication information; In order to make user's normal shutdown, when leaving portable terminal, problems such as data leakage can not occur simultaneously, the system of portable terminal also can obtain the data confidentiality indication information before the flow process that normal shutdown is handled.
In the present embodiment, can protect data in the External memory equipment of portable terminal again in order to make the user, and not need the user manually to obtain the data confidentiality indication information, step 202 can arrange and make portable terminal regularly obtain the data confidentiality indication information.
In the present embodiment, the data confidentiality indication information can comprise in the step 202: the exterior storage routing information of the data that need protection in the External memory equipment, the storage inside routing information of protection etc. is implemented in built-in memory block.
Step 203 according to the data confidentiality indication information, is obtained the exterior storage routing information of the data that need protection in the External memory equipment, and the storage inside routing information of built-in memory block.
In the present embodiment, the exterior storage routing information of the data that need protection in the step 203 can be exterior storage routing information that the system of portable terminal is given tacit consent to, perhaps the exterior storage routing information that defines in the system of portable terminal of user; The storage inside routing information of built-in memory block can be storage inside routing information that the system of portable terminal is given tacit consent to, perhaps the storage inside routing information that defines in the system of portable terminal of user.
