Embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
The invention provides a kind of data guard method, see also shown in Fig. 1,2, be applicable to (as: mobile phone, PDA etc.) on the communication electronic device 1.After communication electronic device 1 externally received a wireless signal, communication electronic device 1 was just to the computing of decoding of this wireless signal, and judged whether wireless signal is data output instruction.Communication electronic device 1 judges when wireless signal is data output instruction that 1 of communication electronic device is externally exported most default protected datas (as: photo album in the communication electronic device, connection book, calendar and short message or the like).Then, after communication electronic device 1 these default protected datas of output, communication electronic device 1 is just deleted described default protected data.
In the preferred embodiment of the present invention, also see also shown in Fig. 1,2, be provided with radio-cell 10 (as: Wireless Transmitters in the communication electronic device 1, Wireless Module), memory cell 20 (MemoryModule), power subsystem 30 (as: rechargeable batteries, Rechargeable Power Module) and central processing unit 40 (Central Processing Unit, CPU).Wherein power subsystem 30 time provides communication electronic device 1 all working powers in start, and 10 of radio-cells transmit according to the communications protocol and the external world.
Wherein, communications protocol can for example be GPRS (General Packet RadioService, GPRS), global system for mobile communications (Global System for MobileCommunication, GSM), infrared ray (Infrared Rays), radio (Radio Frequency, RF) with bluetooth (Bluetooth) one of them.
Be provided with database 201 in the memory cell 20.Database 201 is provided with most protection groups 21 (as: photo album in the communication electronic device, connection book, calendar and short message).The described group 21 that protects comprises most data 211 (as: name, phone, address, birthday, job site or bank cipher in the telephone directory) respectively.Data protection table 22 is available for users to click the data 211 of respectively protecting desire protection in the group 21, and the data 211 of desire protection are defined as default protected data at this.Central processing unit 40 is connected with radio-cell 10, power subsystem 30 and memory cell 20 respectively, and after judging wireless signal and being data output instruction, make radio-cell 10 that each data 211 is sent to outside storage device 100 (as: e-mail or another communication electronic device), delete each data 211 in the memory cell 20 again.
In the present embodiment, also see also shown in Fig. 1,2, the user can utilize the electronic installation (as: network computer or mobile device) with communication function directly or by public network (as: world-wide web, Internet, GPRS network, GSM network, personal portable telephone system (Personal Handy PhoneSystem, PHS) network or Public Switched Telephony Network (Public Switched Telephone Network, PSTN)) are sent to communication electronic device 1 with wireless signal.After the central processing unit 40 of communication electronic device 1 receives wireless signal, then handle, see also shown in Figure 3 according to the following step.
Step 301: received wireless signal is changed, make most packages that have high-frequency signal (high frequency signal) in the wireless signal (as: to separate package by a program of decoding computing, decapsulation), be converted to the fundamental frequency signal (basic frequency signal) that communication electronic device 1 can be handled;
Step 302: judge whether most positions in the fundamental frequency signal have output flag (flag), assert whether mean the foundation that described default protected data is deleted, if, then carry out step 303, otherwise, carry out step 305;
Step 303: have output flag (flag) by most the positions of judging in the fundamental frequency signal, conclude that just received wireless signal is described data output instruction;
Step 304: begin operation that described default protected data is externally exported and deleted, finish this program;
Step 305: most the positions of judging in the fundamental frequency signal do not have output flag (flag), central processing unit 40 concludes that just wireless signal is that communication electronic device 1 is when customary operation, one normal signal that can receive at ordinary times, this normal signal is generally a handshaking instruction, voice signal or letter signal, finishes this program.
Among the present invention; also see also shown in Fig. 1,2, concluding received wireless signal when central processing unit 40 is described data output instruction, and desire is deleted described default protected data; see also shown in Figure 4ly, 40 of central processing units are handled according to the following step:
Step 401: in database 201, respectively protect the data 211 of group's 21 desires protection in searching and the reading of data protection table 22, and the described data 211 of protecting group's 21 interior desires to protect are defined as default protected data at this;
Step 402: according to the data 211 of desire protection in the data protection table 22, to the default protected data of database 201 acquisition protection groups 21;
Step 403: make program that the default protected datas of respectively protecting in the group 21 carry out a coding computing to convert the wireless signal that meets the communications protocol that radio-cell 10 observed respectively to;
Step 404: make radio-cell 10 with described wireless signal directly or by a public network (as: world-wide web, Internet, GPRS network, GSM network, PHS network or Public Switched Telephony Network (Public Switched Telephone Network, PSTN)), externally be sent to storage device 100;
Step 405: according to the default protected data in the data protection table 22, the default protected data in the group 21 is respectively protected in deletion in regular turn.
After communication electronic device 1 is stolen or loses; burglar or winner usually can be with communication electronic device 1 shutdown, to avoid constantly being inquired or locate by telephone (for example being to utilize the base station to find out the position of communication electronic device 1 by police or telecommunications service dealer) by the user.Do not have in shutdown when communication electronic device 1 under the situation of any electric power supply, central processing unit 40 can't be activated.Therefore, in the present invention, also see also shown in Figure 1, communication electronic device 1 also be provided with standby power unit 55 (for example: the battery that can charge jointly with power subsystem 30) and control unit 50 (can be built-in control chip, Micro Chip), standby power unit can in communication electronic device 1 be shut down the back (being that power subsystem 30 does not provide working power) length in (as: 2～3 hours), Be Controlled unit 50 activates, control unit 50 still is provided, radio-cell 10, the work energy that memory cell 20 and central processing unit 40 are required, see also shown in Figure 5, control unit 50 provides the carrying out that receives wireless signal and subsequent step according to the following step after this communication electronic device 1 is shut down:
Step 501: detect the output electric weight of power subsystem 30, judge whether continued power of power subsystem 30, if carry out step 504, otherwise carry out step 502;
Step 502: connect the online of standby power unit 55 and control unit 50, radio-cell 10, memory cell 20 and central processing unit 40, to provide each element required work energy;
Step 503: activate radio-cell 10, memory cell 20 and central processing unit 40, but make its operate as normal;
Step 504: make radio-cell 10 receive wireless signal, and after receiving wireless signal, received wireless signal is changed (as: step 301), continue follow-up step again.
The above, only for a specific embodiment of the best of the present invention, yet data of the present invention are not limited thereto, the any inside of communication electronic device or data that external mechanism produced utilized, and any those who are familiar with this art are in field of the present invention, produce according to the present invention can think easily and variation or modification, all can be encompassed in the claim of following this case.
