Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and the embodiments.Should be appreciated that embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 1 is the flow chart of data guard method first embodiment of portable terminal of the present invention.As shown in Figure 1, the embodiment of the invention provides a kind of data guard method of portable terminal, comprising:
In embodiments of the present invention, determine at first whether portable terminal is in lost condition, when portable terminal is in lost condition, in two kinds of situation: a kind of is that portable terminal is stolen, be in the state of to give back, another kind is that portable terminal is picked up by the people, picks up taker and has a mind to give back, and this moment, portable terminal was in the state of can giving back.Therefore, need send by output device and give back instruction, as " this portable terminal is lost, if can give back, will be deeply grateful! Get in touch with the owner of lost property? " etc. information.Simultaneously, can export choice menus, as "Yes" and "No", for picking up taker or stealing the taker selection, then receive and pick up taker or steal the response of taker, when picking up taker or steal taker selection "Yes" this instruction by input unit, can think that this response is for agreeing to give back response, then dial the designated call number automatically, and can behind end of conversation, close this portable terminal, to prevent the person of picking up or to steal taker and steal data; When picking up taker or stealing taker and select "No" or take anyly when desiring to withdraw from the operation of this program, can think that this response gives back response for refusal, then deletion preestablishes and needs the data that delete automatically.This appointment receiving number and above-mentioned designated call number are predefined other mobile terminal number of the portable terminal owner, can be duplicate numbers, also can be different numbers.
The embodiment of the invention is by providing a kind of data guard method of portable terminal; when portable terminal is in lost condition,, data are carried out different processing according to the response of giving back that receives; strengthen safety of data in the portable terminal effectively, and reduced user's loss.
Fig. 2 is the flow chart of data guard method second embodiment of portable terminal of the present invention.As shown in Figure 2, on the basis of said method first embodiment, step 101 can comprise:
In embodiments of the present invention, can determine whether portable terminal is in lost condition by number of ways.Be replaced when detecting SIM card, and when surpassing predetermined threshold value, can determine that this portable terminal is in lost condition by the number of times that input unit receives bad password continuously; Perhaps ought detect safe digital storage (Secure Digital Memory; Hereinafter to be referred as: SD) card is replaced, and when surpassing predetermined threshold value by the number of times that input unit receives bad password continuously, can determine that this portable terminal is in lost condition; Perhaps ought receive and check the enciphered data request message, and when surpassing predetermined threshold value by the number of times that input unit receives bad password continuously, promptly steal taker and desire to check the enciphered data of storing in the portable terminal,, can determine that this portable terminal is in lost condition as address list etc.; Perhaps ought receive unlocking request message to locked input unit, and when surpassing predetermined threshold value by the number of times that input unit receives bad password continuously, promptly under the blocked situation of the input unit of portable terminal, steal taker and desire to carry out release, can determine that this portable terminal is in lost condition.
Data in the embodiment of the invention can comprise: be stored in all data such as photo in SIM card, SD card or the portable terminal, short message, address list, log, picture, audio frequency, video.
Further, when deletion preestablishes the data that need deletion, can also comprise: the locking input unit, can't operate portable terminal at this moment so that steal taker.
Further, preestablish before the data that need deletion, can also preestablish the data that need send, cause losing of significant data to avoid deleted data to specifying receiving number to send in deletion.
The step that above-mentioned deletion preestablishes the data that need deletion can comprise: according to the level of security of the data that preestablish the needs deletion, and deleted data successively from high to low.Data in the portable terminal can be provided with different level of securitys according to its significance level, as be set to that the data of high level of security need at first be sent to the appointment receiving number, and deletion immediately after transmission, follow-up processing to the data that do not need to send is also deleted successively by data from high to low.For example, can be divided into three grades to the level of security of all data, be followed successively by one-level, secondary and three grades from high to low, wherein most important one-level data need be encrypted storage, just can be accessed after promptly must the correct password of input, at first send most important one-level data to specifying receiving number, then delete this one-level data, delete important secondary data then, three grades of not too important data of last deletion again.
In technique scheme, sending the step of giving back instruction by output device can comprise: send by display screen or loud speaker and give back instruction; The step that receives the response of giving back instruction by input unit can comprise: receive giving back the response of instruction by keyboard, touch-screen or microphone.
