In practical application, IMSI (InternationalMobileSubscriberIdentificationNumber, international mobile subscriber identity) code is stored in SIM (SubscriberIdentityModule, subscriber identification module) card in, be difference mobile subscriber effective information.
Therefore, the present inventor considers, the IMSI code of the SIM card that user inserts in intelligent terminal can be utilized to be encrypted computing (such as AES encryption) as the password that double secret key user is arranged, and data computing obtained store.Compare the existing method be stored in the form of plain code by the password of user's setting in intelligent terminal; the present invention does not store password that user arranges but the data obtained after the password encryption that arranges number of users of memory IMSI code in intelligent terminal; greatly can improve and crack difficulty, be conducive to the privacy protecting intelligent terminal user.
Technical scheme of the present invention is described in detail below in conjunction with accompanying drawing.
The invention provides a kind of method protecting intelligent terminal user privacy, its idiographic flow as shown in Figure 1, can comprise the steps:
S101: obtain the password that user is arranged.
In practical application, user can take the mode locked to protect the privacy of oneself usually.Such as, by the screen of locking intelligent terminal, or the file of privacy of user can be stored to protect privacy of user in locking intelligent terminal.In fact, user can arrange the password for locking or unlocking in advance on intelligent terminal, arranges with the locking that this completes screen or file in intelligent terminal.
Therefore, in the embodiment of the present invention, before locking the screen of intelligent terminal or file, intelligent terminal can obtain user for the password set by the screen of intelligent terminal or file, so that the follow-up password that can arrange based on user carry out locking setting.Wherein, pre-set by user for the screen of intelligent terminal or the password of file, its form can be set of number or a pattern etc.
Further, the present inventor finds, in practical application; in order to carry out safeguard protection to the SIM card inserted in intelligent terminal; usually in SIM card, storing PIN, ((PersonalIdentificationNumber, PIN) code, prevents others from usurping with this.In fact, the PIN code of SIM card can be arranged by user.Therefore, in the embodiment of the present invention, the password that user is arranged can be the PIN code be stored in SIM card.
In the embodiment of the present invention, to carry out being locked as example for the screen of intelligent terminal, in practical application, PIN code screen locking can be set up in the screen locking option of intelligent terminal.Like this, after user selects PIN code screen locking, in order to the password that the PIN code of SIM card is arranged as user, first intelligent terminal can detect the state of SIM card, if SIM card is in PIN code verification state, then the PIN code that can store in reading SIM card, and the password that the PIN code of reading and user input is compared, if both are consistent, then using the PIN code of SIM card as user for intelligent terminal screen set by password.Like this, subsequent user inputs correct PIN code and can unlock.
In fact, often there is an initial password arranged by the supplier of SIM card in the PIN code due to SIM card, therefore, there is the situation that user does not know the PIN code of SIM card.Therefore, in the present invention, the object that the password that the PIN code of reading and user input is compared is to confirm that user has known PIN code accurately, avoids carrying out locking setting when user does not know the PIN code of SIM card and cause user itself also cannot unlock.
S102: utilize the IMSI code of SIM card to be encrypted computing to the password that user is arranged, the first data computing obtained store.
Particularly, based on the consideration cracking difficulty of IMSI code in SIM card, intelligent terminal is after the password being obtained user's setting by step S101, the IMSI code of SIM card can be utilized to be encrypted computing to the password that user is arranged, such as, AES (AdvancedEncryptionStandard, advanced encryption standard) encryption can be carried out.
Afterwards, cryptographic calculation can be obtained the first data and store by intelligent terminal, thus avoids the password by user is arranged to be stored in intelligent terminal with the form of plain code.Like this, make assailant from intelligent terminal, directly cannot obtain the password of user's setting, the acquisition difficulty of the password that adding users is arranged.
In practical application, user can be called the screen locking password of intelligent terminal for the locking of the screen of intelligent terminal or the password set by unlocking; The screen locking password of the intelligent terminal that user is arranged can not be stored in intelligent terminal, and the first data that the screen locking password encryption computing arranged based on user obtains are stored.
Further, based on the consideration cracking difficulty of IMSI code in SIM card, in the embodiment of the present invention, intelligent terminal, after the IMSI code of reading SIM card, can create the file of running after fame with IMSI code.Like this, after the cryptographic calculation by step S102 obtains the first data, the first data can be stored in the file of running after fame with IMSI code.
In practical application, the file of running after fame with IMSI code of establishment can also be used for storing the private data of user.Such as, under the file of running after fame with IMSI code created is mounted to data (data) catalogue of intelligent terminal, like this, user can be saved to individual privacy data in this file.
Screen locking password is stored in the document files of specifying in intelligent terminal by existing intelligent terminal based on operating system, such as, the intelligent terminal of Android (Android) system, is stored in the screen locking password that user is arranged in the file of password.key by name with the form of plain code usually.Like this, easily for assailant provides direction of attack, increase the potential safety hazard of privacy of user in intelligent terminal.
In the solution of the present invention, the password encryption arranged is obtained the first data be stored in the file of running after fame with the IMSI code of SIM card based on user.On the one hand, in order to obtain the screen locking password of user's setting to unlock, compared to the existing document files of specifying based on operating system, the difficulty that the file victim of running after fame with the IMSI code of SIM card finds is larger.On the other hand, what store in the file of running after fame with IMSI code is the first data that the password encryption arranged based on user obtains, and is not the password that user is arranged.That is, even if assailant also directly cannot obtain the password that user arranges finding the file of running after fame with IMSI code from intelligent terminal, greatly strengthen the fail safe of privacy of user in intelligent terminal.
In practical application, when the password that user is arranged is the PIN code of SIM card, after utilizing IMSI code encryption PIN code, can be stored in the file that IMSI code is run after fame in intelligent terminal by encrypting the first data of obtaining, also can not the first data of obtaining of storage encryption.
When the first data that not storage encryption obtains, if when follow-up needs unlock, intelligent terminal can obtain the PIN code stored in the IMSI code of SIM card and SIM card; Afterwards, be encrypted computing with the IMSI code obtained for the PIN code of double secret key SIM card, obtain the first data.In fact, if delete the file storing screen locking password place in existing intelligent terminal, the loss of screen locking password will be caused, thus cause the lockout failure of intelligent terminal, the safety of privacy of user cannot be ensured.And in the solution of the present invention, even if assailant deletes the file of running after fame with IMSI code, intelligent terminal also can regenerate the first data that PIN code and IMSI code based on SIM card obtain, and can't cause the lockout failure of intelligent terminal, enhance the security protection of intelligent terminal.
More preferably, in the embodiment of the present invention, when the password that user is arranged is the PIN code of SIM card, after the first data obtained by the cryptographic calculation based on PIN code store, PIN code can also be utilized the file encryption of running after fame with IMSI code, strengthen the security protection of file.
Correspondingly, before opening the file of running after fame with IMSI code user, need to be decrypted this file.Particularly, before opening the file of running after fame with IMSI code user, can the PIN code of reading SIM card, and after receiving the unlocking pin that user inputs for this file, the unlocking pin that user is inputted and the PIN code comparison of SIM card; If both are consistent, then decipher this file.
S103: after receiving the unlocking pin of user's input, reads IMSI code from SIM card, and utilizes the IMSI code read to be encrypted computing to the unlocking pin that user inputs to obtain the second data; If the first data consistent of the second data obtained and storage, then carry out unlocking operation.
In the embodiment of the present invention, after intelligent terminal is locked by the password that user is arranged, if receive the unlocking pin of user's input, then need to verify the unlocking pin of user's input, if verification succeeds, then can carry out unlocking operation.
Wherein, the unlocking pin of user's input can be the unlocking pin of screen, and correspondingly, the unlocking operation carried out is specially the unlocking operation of screen.Or the unlocking pin of user's input is specially the unlocking pin of file; Correspondingly, the unlocking operation carried out is specially the unlocking operation of file.
Although, in technical scheme of the present invention, the password arranged may be compared when the password arranged before intelligent terminal does not store user and verify before the unlocking pin of user's input and user.But, store in intelligent terminal and utilize IMSI code to be encrypted to the password that user is arranged the first data that computing obtains.
Therefore, in the embodiment of the present invention, the IMSI code that can store in reading SIM card; Afterwards, utilize the IMSI code read to be encrypted computing to the unlocking pin that user inputs and obtain the second data.Like this, the first data of the second data obtained and storage can be compared, if unanimously, then carry out unlocking operation.
Further, in the embodiment of the present invention, when the password that user is arranged is the PIN code of SIM card, although do not store the password of user's setting in intelligent terminal with the form of plain code, but intelligent terminal can read the PIN code of storage from SIM card, afterwards, the unlocking pin that the PIN code of reading and user input is compared, if consistent, then unlocking operation can be carried out.
When intelligent terminal same as multiple users share, the SIM card that intelligent terminal inserts often through each user is distinguished.Therefore, by the solution of the present invention, if user is the PIN code of SIM card for the password set by the screen of intelligent terminal or file, then for different users, the screen locking password of intelligent terminal is also different.
Screen locking password is obtained with this because intelligent terminal can read PIN code from the SIM card of user's insertion, therefore, in intelligent terminal hand-over, transfer both sides and do not need shared screen locking password, the PIN code that recipient inputs the SIM card of oneself can unlock intelligent terminal, simplifies the hand-over of intelligent terminal.And, because private data can be stored in the file of running after fame with the IMSI code of SIM card by user.Therefore, before transfer intelligent terminal, even if the file storing private data is not deleted by transfer side, recipient cannot open this file when not knowing the PIN code of SIM card of transfer side, simplify the hand-over of intelligent terminal, and substantially increase the fail safe of the privacy of user in intelligent terminal hand-over.
In technical scheme of the present invention, with the IMSI code of SIM card, computing is encrypted to the password that user is arranged, and the first data that computing obtains are stored, and do not store the password of user's setting.Like this, if user loses intelligent terminal, no matter current other users holding intelligent terminal change or do not change the SIM card of original subscriber, current other users holding intelligent terminal directly cannot obtain the password that user is arranged from intelligent terminal, and be difficult to the ISMI code of the SIM card obtaining original subscriber, thus the unblock of intelligent terminal cannot be carried out, ensure the safety of private data in the file of running after fame with the IMSI code of the SIM card of original subscriber in intelligent terminal.
