The present invention has two kinds of tupes, the first pattern is applicable to terminal binding, user is after first time Successful login terminal software, acquisition equipment international mobile subscriber identity (InternationalMobileSubscriberIdentificationNumber, IMSI), international mobile equipment identification number (InternationalMobileEquipmentIdentificationNumber, IMEI) information being kept in SharedPreferences.According to preserving facility information and existing equipment IMEI, IMSI compare when destroying service operation, determine whether to need destruction.
Fig. 1 is the flow chart of destroying method embodiment one of the present invention, and as shown in the figure, the present embodiment specifically comprises the steps:
Step 101, an IMEI of a mobile terminal and IMSI, by after mobile terminal first Successful login, is kept at this locality by user; And the first broadcast to be added in alarm clock management AlarmManager timer and to broadcast;
Successful login variable set up is true by step 102;
Step 103, the radio receiver of mobile terminal receives the first broadcast, starts the service of destruction;
Concrete, during user's first time Successful login, IMSI, IMEI information of equipment is kept in SharedPreferences, will represents that the variable successedLogin of successfully logged software is set to true simultaneously.After the success of user's first time manual entry, first broadcast Constants.ACTION_ACTIVATE_DESTROY is added in alarm clock management AlarmManager, and constantly sending this broadcast with the interval time of 120 seconds, radio receiver starts the service of destruction after receiving this first broadcast immediately.
Step 104, after start, radio receiver receives the start self-starting broadcast that system sends;
Step 105, judges whether Successful login variable is true, then sends the second broadcast in this way;
Concrete, mobile terminal is started shooting again afterwards, radio receiver is then utilized to receive start self-starting broadcast, i.e. android.intent.action.BOOT_COMPLETED broadcast, first whether the value of judgment variable successedLogin is true, if satisfied condition, just the second broadcast and Constants.ACTION_ACTIVATE_DESTROY is added in alarm clock management AlarmManager, such as, and with very first time interval, the time of 120 seconds constantly sends this broadcast.
Step 106, when radio receiver receives the second broadcast, monitors client identification module (SubscriberIdentityModule, SIM) in mobile terminal;
Concrete, after radio receiver receives the second broadcast, start the service of destruction immediately, monitor the state of SIM card.
Step 107, if None-identified is to SIM, or the 2nd IMEI of the mobile terminal got is inconsistent with the local IMEI preserved, or the 2nd IMSI got is inconsistent with the local IMSI preserved, and mobile terminal is destroyed.
Concrete, if None-identified is to SIM card, such as, is without SIM card state, or has SIM card state, but the IMSI that the 2nd IMSI got or the 2nd IMEI information and SharedPreferences preserve or an IMEI information inconsistent, all open from destroying.
Destroying is exactly the information deletion preserved this locality, such as, information in delete database file, empty all variablees (comprising user account, password, IMEI, IMSI, setting option) that SharedPreferences preserves, then destruction mark destroy is set to true, preserves in SharedPreferences.
If network is normal, then the software time of destroying is sent to server.Kill current process, and the view layer run, service layer process.
If wished when again logging in next time, then can point out that " software is self-destruction, reinstalls after please unloading! ", cannot enter this application, software prohibits the use.
The second tupe of the present invention is applicable to server end binding: when server end typing user profile, user ID, password, IMSI, IMEI are bound, when having remote destroying request, can go to search according to IMSI, IMEI the user needing to destroy, then destroy operation accordingly.
Fig. 2 is the flow chart of destroying method embodiment two of the present invention, and as shown in the figure, the present embodiment specifically comprises the steps:
Step 201, server receives to destroy and asks and preserve in lists, and the request of destruction comprises user ID, and user ID is bound with user cipher, IMIS and IMEI phase;
Concrete, if having destruction requirement to the user of certain binding, then choose this user at dispatching desk, send and destroy request CC2SS_KILL_USR_REQ to server, destruction request is carried by destruction user ID.
After server receives the destruction request of dispatching desk, in these three tables, PTT_HEAP.ZXYongHu_Record, PTT_HEAP.YongHu_Record, PTT_DISK.YongHu_Info find this user, and arrange the destroy state of this user.
Step 202, it is no that mobile terminal judges that destruction is masked as, and sends and destroy query messages, destroy an IMSI and an IMEI that query messages comprises mobile terminal to server;
Concrete, after terminal starts the service of destruction, if destroying mark destroy is false, then with very first time interval, within such as 120 seconds, send the inquiry of destruction query messages with or without destruction requirement to server, the destruction query messages of transmission comprises the first IMSI information, and an IMEI information, the first IMSI information preferably after md5 encryption, and an IMEI information.
Step 203, server searches bound user ID according to an an IMSI and IMEI;
Concrete, after server receives and destroys query messages, by first IMSI information of carrying in message, and an IMEI Information Authentication binding relationship, after checking is legal, by the user ID that binding relationship finds terminal corresponding, and search by user ID the destruction request record whether having and destroy this user in PTT_HEAP.YongHu_Record table.
Step 204, server finds first user ID in lists, by the 2nd corresponding for the user ID of preserving in list IMSI, and the 2nd IMSI after encryption is sent to mobile terminal;
Step 205, mobile terminal judges that the 2nd IMSI after encryption is consistent with the IMSI after local encryption, then mobile terminal is destroyed.
Concrete, when mobile terminal obtains the destruction acknowledge message KILL_USR_CNF_MSG that server returns, judge second IMSI information after md5 encryption will destroying mobile phone of carrying in server return messages whether encrypt with existing equipment after an IMSI consistent, if equal and destroy flag bit be 1, then start Shredding Process.
Destroying is exactly the information deletion preserved this locality, such as, information in delete database file, empty all variablees (comprising user account, password, IMEI, IMSI, setting option) that SharedPreferences preserves, then destruction mark destroy is set to true, preserves in SharedPreferences.
If network is normal, then the software time of destroying is sent to server.Kill current process, and the view layer run, service layer process.
If wished when again logging in next time, then can point out that " software is self-destruction, reinstalls after please unloading! ", cannot enter this application, software prohibits the use.
