Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further introduced, but not as the qualification to invention.
A kind of portable terminal comprises memory cell, warning device, information auto delete device, information back-up device and information recovery device.
Wherein: the various resource informations that store the user in the memory cell, also store the original user identification code of mobile phone (International Mobile Subscriber Identification Number:IMSI) information, store also that type of alarm that the user sets and target, information are deleted, backup and the pairing command code of recovery operation etc.
Warning device is in order to make mobile phone after losing, when new user changes SIM card and uses, can in time trigger warning function, the relevant information of neocaine is sent to the predefined target location of original subscriber, make original user know the information of using the new user of this mobile phone, take appropriate measures.With reference to shown in Figure 1, this device comprises: IMSI reading unit 11 is used for reading the IMSI of new SIM card; Condition authentication unit 12, the IMSI that is used for relatively reading and the IMSI of memory cell judge whether unanimity; Trigger alarm unit 13, be used under the inconsistent situation of the IMSI of IMSI that reads and memory cell, call predefined triggering alarm operation mode; Warning performance element 14 sends warning according to trigger message to the user.
With reference to shown in Figure 2, lose when user mobile phone, change new SIM card after, carry out following alarming step:
Step 101: the IMSI in the reading SIM card;
Step 102: the IMSI that stores in the IMSI that reads and the memory cell is compared,, then carry out next step,, then do not handle if identical if inequality;
Step 103: call predefined triggering alarm operation mode, this mode can be called etc. for sending note to setting the user, mode selected can be set priority, carry out successively, also can select one to carry out, this selection is set when the cell phone system initialization in advance;
Step 104: warning message is sent to the predefined position of user.
The information auto delete device is the active response measure in order to prevent the leakage of information on the mobile phone and to carry out in terminal.With reference to shown in Figure 3, this device comprises the trigger condition receiving element 21 that connects successively, be used to receive the extraneous command code that the mobile phone storage resources is called, this command code can be the PIN code of user's input, the information that service password or individual set in advance, different command codes is corresponding to the deletion action of different storage resources information; Data processing unit 22 is used to handle the trigger message that receives, and judges whether trigger message is consistent with predefined information, if then send triggering command to memory management unit 23; Memory management unit 23 is used for finishing the deletion to the resource information of memory cell.Because data processing unit 22 can judge whether to carry out information resources deletion, the trouble of having avoided misoperation to bring by repeatedly receiving trigger condition.
With reference to shown in Figure 4, portable terminal can be set different command codes and delete different information types respectively when carrying out information deletion, for example: the PIN code of setting input error is the deletion full detail, when calling short message, the command code of input error is the deletion short message, or the like; This command code and respective operations be arranged on the cell phone system initialization time set.Portable terminal to information deletion by following step:
Step 201: starting up of terminal, maximum three input PIN code, allowing repeatedly to import is in order to prevent that misoperation from causing the mistake of information to delete;
Step 202: whether the PIN code information of judging input is all consistent with the PIN code information of storage, and if not, then expression needs the deletion stored information, carries out next step, if then do not handle;
Step 203: according to the definite storage resources information that will delete of the PIN code of input;
Step 204: deletion chosen content.
In above-mentioned steps, also can call item to each information resources, as: note, telephone numbers etc. are setting code respectively, difference input operation sign indicating number when calling each resource, if command code is not right, the deletion corresponding informance, step is similar.
The information back-up device exports to cellphone information on the extraneous storage medium, information can be returned to new cell-phone as required.As shown in Figure 5, this device comprises the backup condition trigger element 31 that connects successively, is used for the request that the user sends data backup; Backup content choice unit 32 is used for selecting to want backed up data; DEU data encryption unit 33 is used for the needs backed up data is encrypted; Data lead-out unit 34 is used for Backup Data is derived.
With reference to shown in Figure 6, portable terminal is carried out following steps when carrying out data backup:
Step 301: the user sends data backup requests, and this request can utilize the setting operation sign indicating number to realize, different command codes is set can corresponding different information back-up requests, set when this is set in the cell phone system initialization;
Step 302: determine the various information datas that user's needs back up according to request, determine its form: address list form, messaging format, memorandum form, external memory type or the like;
Step 303: the backup content-data is encrypted, prevented to be usurped by other people;
Step 304: data encrypted is stored in the extraneous storage medium.
The information recovery device, be used for user's lost mobile phone after, lose the original information resource, utilize the outside information that has backed up to rebulid the original resource of user.With reference to shown in Figure 7, this device comprises the write operation authentication unit 41 that connects successively, is used for that the user is imported corresponding information and receives and write the permission judgement; Data decryption unit 42 is used for the data decryption on the exterior storage medium; Content choice unit 43 is used to select the resource that will import; Data importing unit 44 is used to import data.
Portable terminal is connected said apparatus earlier when carrying out the data recovery with exterior storage medium, carry out following steps:
Step 401: portable terminal receives user's legal information recovery request;
Data restoring request is determined by the input operation sign indicating number, can set different command codes and recover different information types respectively, as: note, the recovery of telephone directory can be asked by different command code inputs, recover when also can command code being set to a plurality of information of same, set when this is arranged on the cell phone system initialization.
If the request operation code of input is identical with the recovery operation sign indicating number in the memory cell, show that then portable terminal allows data to recover, this request is legal.
Step 402: the data on the exterior storage medium are carried out data processing, comprise deciphering, format conversion etc., make things convenient for data to read in;
Step 403: the information content of selecting to determine recovery according to user's information recovery request;
Step 404: with relevant position in the corresponding memory cell of data importing.
