Many variations and modification in following embodiment, can also realize the application technical scheme claimed.
The first embodiment of the present invention is related to a kind of creation method of private space, and idiographic flow is as shown in Figure 1.
The creation method of private space shown in Fig. 1 can be used in the user terminal, and wherein the user terminal can be
Such as smart mobile phone, tablet personal computer, personal digital assistant etc..Specifically, the creation method of the private space that Fig. 1 is related to
Flow can include：
In a step 101, detect whether that user chooses operation to private space establishment entrance.
Specifically, user is being detected to private space when choosing operation of entrance of establishment, into step 102；Otherwise
Continue to detect whether that user chooses operation to private space establishment entrance, untill entering step 102.
Such as create and operated into confession user there is provided private space in the setting interface of terminal, when user needs
, specifically can be according to practical application by the establishment chosen operation, realize private space to the entrance when creating private space
Setting, is not limited herein.
In a step 102, the space for dividing default size is used as private space.
Specifically, the space that default size is divided from the read-only storage of terminal is used as private space.
It should be noted that when choosing operation of entrance is created to private space detecting user, from the read-only of terminal
The space of the default size divided in storage, the fixed value that can be set for system, i.e., the private space created every time is all solid
Determine size；The value that can also be arranged as required to for user, the size of the private file such as stored as needed creates suitable
The private space of size, can specifically select suitable mode to be set, is not limited herein according to the actual requirements.
Such as, needed in user to the relevant information for the designated contact being stored in mobile phone, such as telephone number, therewith
Message registration, the short message content of correlation, or during specified file progress secrecy, entrance is created by triggering private space, it would be desirable to
Private space of the content storage maintained secrecy to generation.
It is noted that user can use non-private space (general spatial not store privacy number in private space
According to the space with significant data) all application programs, the application journey for being specific to this space can also be installed in private space
Sequence.
In addition, in order to ensure that the data that user is produced under private space using application program will not be obtained in normal system
, the private space created in present embodiment, its data are independent management, that is to say, that user operates hidden in private space
The data that all data and user that private application program is produced are produced in application program of the private space using normal system
It will be stored in the privately owned internal memory of private space, user can not check this data in normal system.
In addition, it is noted that in the safety of the private space in order to further improve user's establishment, present embodiment
Private space is created by using internal memory camouflage mechanism, private space is hidden so as to reach, i.e.,：Created in present embodiment
Private space, when calculating the remaining space of read-only storage, private space is calculated within free space.Further, since
The space of the private space meeting read-only storage of occupied terminal, the consumption of memory space can expose the presence of private space, therefore, only
Read storage remaining space it is not enough when, data stored by removing in private space, and discharge the space of private space occupancy,
So as to avoid private space from being exposed.According to this establishment mode so that private space knows that other people are basic except founder
It can not know.
Such as, the read-only storage ROM of terminal space is 10G, and the data that user stores in general spatial have made
With 3G, after user creates the private space of 1G size, ROM remaining spaces are 6G, now, because 1G spaces are special
Different sign, can be calculated within free space, therefore the ROM remaining free space that system is shown remains as 7G.Work as user
When writing 6.5G data into ROM in normal system, because the data to be write are more than the remaining available skies of ROM
Between, it is now, automatic to remove the data of 0.5G in private space, and discharge the space of the 0.5G, residue used in private space
0.5G can be still calculated within free space.
Limited it should be noted that these are only for example, not constituted to technical scheme.
In actual applications, the remote server that the data timing in private space is synchronized to and specified can also be set,
The privacy server of such as special storage private data, so in user's changes terminal, or other people are deposited by malice to terminal
Storage data occupy read-only memory space, know the read-only storage real surplus space of present terminal, finally obtaining causes private space
When the data of middle storage are eliminated, the founder of private space can be reacquired to private data from privacy server, it is to avoid
The loss of user and trouble, specifically can according to actual needs set, not be limited herein.
User uses for convenience, the private space created in the terminal in present embodiment, is not limited to one, user
Can be as needed, multiple private spaces are created in the terminal, and multiple private spaces can be used simultaneously, and each privacy is empty
Between be individually present, preserve data in the inner and be independent of each other.
In addition, in order to further facilitate user, the user for creating private space using same terminal is also not limited to one,
Such as the test machine that company uses, possess each employee of access right and can be created as needed in the test machine and belong to
The private space of oneself, can specifically set according to practical application, not be limited herein.
In step 103, generation accesses the key of private space.
Specifically, key packet contains the public key for unlocking private space and the private key for verification public key.
It should be noted that the access private space generated in the security in order to ensure private space, present embodiment
Key automatically generated by system, such as by terminal inner Key generating unit generate, or by with terminal set up communicate to connect
Remote server generation.
In addition, in actual applications, user uses for convenience, the key for accessing private space can be by user certainly
Row setting, so as to facilitate user to remember the public key for unlocking private space, naturally it is also possible to which the entrance for setting public key is only provided,
The public key that private key is set according to user is allocated by system, thus further lifted key security, in be used for unlock it is hidden
The public key in private space can be by user's sets itself.
On the generating mode for the key for accessing private space, it can specifically be set, do not limited herein according to practical application
System.
At step 104, public key is informed into user, terminates the establishment operation of this private space.
Specifically, according to predetermined manner, public key is informed into user.
Can be after key generation, directly to exist it should be noted that public key to be informed to the predetermined manner of user institute foundation
The display interface of present terminal shows the public key for unlocking private space, or in order to point out security, can provide one
Account sets interface, allows user's input to receive the account of checking information, the phone number of such as founder, mailbox, QQ number code,
Wechat number etc., is then handed down to user, and for security, can also set the public affairs for being issued to user account by public key
Key information is burn-after-reading attribute, i.e., the information, or auto-destruct in the given time are automatically deleted after user checks, is closed
In burn-after-reading or the implementation of timed destroying, those skilled in the art can realize according to prior art, not make herein
Specifically repeat.
Compared with prior art, the creation method of the private space provided in present embodiment, it is independent by creating data
The private space of management, and distributed for the private space created for unlocking the key into the private space, in unblock
During public key verifications success, it can just enter private space, the data stored in private space be accessed, so as to ensure that private data
With the security of vital document.In addition, being deposited by setting the private space created to be present in the read-only of terminal in the form of hiding
Chu Zhong, i.e., when calculating the remaining space of read-only storage, private space is calculated within free space, and in read-only storage
Remaining space it is not enough when, the data stored by directly removing in private space, the space that release private space takes so that
Avoid other people and read-only memory space is occupied to terminal storage data by malice, know that the read-only storage of present terminal is actual surplus
Complementary space, finally knows there is private space in terminal, has further ensured the private data and important text being stored in terminal
The security of part.
Second embodiment of the present invention is related to a kind of creation method of private space.Present embodiment is in the first embodiment party

Private space creates when choosing operation of entrance, into step 202；Otherwise continue to have detected whether that user creates private space
Entrance chooses operation, untill entering step 202.
In step 202., the space for dividing default size is used as private space.
In step 203, generation accesses the key of private space.
It should be noted that terminal can quickly recognize the solution that user inputs when terminal is in the lock state for convenience
Lock cipher is to enter non-private space, i.e. general spatial, still enters private space, it will usually will be used to unlock private space public affairs
The first place of key is set to preset parameter, such as " 0 ", and in order to avoid unlocking the public key of private space and the solution of unblock general spatial
The first parameter of lock cipher is identical, and which space is system can not be recognized quickly into, in present embodiment, defines the position of public key
Number is more than the digit of unblock general spatial unlocking pin, and limits the digit of unblock general spatial PUK as fixed value.Separately
Outside, in order to ensure that public key has enough securities, it will usually by public key setting be 7 Arabic numerals.
In actual applications, the digit of public key is not limited to 7, is also not limited to Arabic numerals, in order to further
Ensure private space and be stored in the securities of data in private space, can be by improving the complexity of public key, such as by public key
It is set to be made up of any one in capitalization, lowercase, Arabic numerals, special symbol or any combination, and
The first place of public key can also provide authority and be set by user, specifically can according to actual needs select, not be limited herein.
, can also be by when generation accesses the key of private space in addition, the security in order to be further ensured that private space
System or user's setting unblock private space allow error number of times and more than after the errors of setting to the guarantor of private space
Protect facility.
Such as, when terminal is in the lock state, there is user to input public key, now system travels through private key from private key storehouse
Matched with public key, if the private key not matched, " key is not present " is shown in the display interface of terminal, if currently
Any key (private space is not present in present terminal) is not present in terminal, similarly " key is not present " is pointed out.Work as user
The public key errors number of input exceedes number of times set in advance, and such as 20 times, then system judgement has intrusion behavior, automatically turns on and protects
Private space pattern is protected, such as within 24 hours, any public key is inputted and all points out " key is not present ".If the private of matching
Key, the then physical address carried by private key finds corresponding private space in the ROM of terminal, reads in private space storage
Data storage reason so that do not influence user input unlocking pin on the premise of, it is to avoid unblock private space public key by him
People's Brute Force.
In step 204, public key is informed into user.
Specifically, according to predetermined manner, public key is informed into user.
It should be noted that predetermined manner can include following any one or any combination：In the display interface of terminal
Display public key, the phone number inputted with short message mode to user issue public key, the hand inputted in voice call mode to user
Machine number issues public key, specifically can select suitable mode that public key is informed into user according to practical application, not be limited specifically.
In addition, the security in order to ensure private space, can set the public key for unlocking private space and only create
Success private space, generation is accessed after the key of the control, informs user once.
Because step 201 to step 204 and the step 101 in first embodiment are to 104 roughly the same, it is intended to：In inspection
Measure user and when choosing operation of entrance is created to private space, the space that default size is divided from the read-only storage of terminal is made
For private space, and the key for accessing private space is generated, then according to predetermined manner, public key is informed into user, herein no longer
Repeat.
In step 205, the data of private space are encrypted using private key, terminate the establishment behaviour of this private space
Make.
It should be noted that being specifically included for the private key that the data to the corresponding private space of key are encrypted：Test
Card part, encryption part and storage part.
Wherein, verification portion is the data in the precalculated position extracted from public key, and such as setting is tested from rear 6 conducts of public key
Demonstrate,prove part.
