Referring to Fig. 2, Fig. 2 is the flow chart that the application realizes another embodiment of method for secret protection.Present embodiment In, realize that method for secret protection includes the following steps：

Step S201：Mobile terminal obtains the target private data of pre- protection object contact person according to user input instruction Data type.

Mobile terminal is provided with the interface for different types of data being arranged secret protection.It is inputted by the interface in user When the instruction of secret protection is arranged at least one data type, the contact person that mobile terminal chooses user is as pre- protection mesh Contact person is marked, and according to instruction input by user, obtains the data type of the target private data of the object contact person, such as Image type, text information type, audio types, video type etc..

Specifically, mobile terminal is provided with the interface for different types of data being arranged secret protection in man-machine interface, such as wraps It includes and secret protection is arranged to the communication information, image information, acoustic information, video information, all information etc..Accordingly, it is obtaining To it is input by user to object contact person setting the communication information protect instruction when, acquisition for mobile terminal message registration, short message etc. Data type of the text information type as target private data.It is input by user to object contact person setting image getting When the instruction of information protection, data type of the acquisition for mobile terminal image type as target private data.Getting user When the instruction of input protected to object contact person setting acoustic information, acquisition for mobile terminal audio types are as target privacy number According to data type.When getting the instruction input by user protected to object contact person setting video information, mobile terminal Obtain the data type of image and audio types as target private data.Input by user object contact person is set getting When setting the instruction of all information protections, i.e., to all information related with the object contact person in local, such as message registration, short Breath, memorandum, calendar, image, audio, video etc. carry out secret protection, all text informations of acquisition for mobile terminal, image, sound Data type of the frequency type as target private data.

Step S202：The characteristic of object contact person described in acquisition for mobile terminal.

Mobile terminal is provided with the interface of the characteristic of acquisition object contact person in advance, is set by the interface in user When setting advance acquisition characteristics data, mobile terminal acquires the name of object contact person, face spy from the information of object contact person Sign, voiceprint it is at least one to identify the private data of object contact person, and as characteristic be stored in it is mobile eventually In the preset path at end.Whether mobile terminal judges pre- in the preset path when obtaining user's input secret protection instruction There is the characteristic, if so, then mobile terminal directly acquires the characteristic to prestore, if it is not, mobile The characteristic of object contact person described in terminal-pair carries out instantaneous acquiring.Certainly, in other embodiments, mobile terminal also may be used It is set as, when obtaining user's input secret protection instruction, directly adopting the characteristic of the object contact person immediately Collection.

Mobile terminal is acquired the characteristic of the object contact person and is specifically described, mobile terminal acquisition The name of object contact person, face-image, voiceprint at least one as characteristic, wherein the characteristic of acquisition With target private data type matching, to identify the target private data.For example, if the data type includes word letter Type is ceased, then at least acquisition object contact person name is as characteristic, if the data type includes image class, at least The face feature of acquisition object contact person at least obtains mesh as characteristic if the data type includes audio class The voiceprint of contact person is marked as characteristic.Certainly, mobile whole if the data type is image class or audio class End can also acquire the name of object contact person as characteristic, so that it includes the object contact person name to search out title Image class or audio related data.It should be noted that in other embodiments, the feature data types of the acquisition also can be by User is configured by the interface that mobile terminal provides, therefore the application is not especially limited the acquisition of feature data types.

Further specifically, when being acquired characteristic, if the type of the characteristic of required acquisition includes surname Name, then mobile terminal acquires the name information of the object contact person as characteristic from contact list information.

If the feature data types of required acquisition include face feature, mobile terminal is obtained from contact list information It takes the personal images of object contact person and carries out Face datection, if the personal images can accurately obtain face characteristic, Characteristic of the face characteristic as object contact person is obtained from the personal images.If personal images cannot be obtained accurately The personal images of object contact person can not be got in face characteristic or contact list information, mobile terminal then prompts user Face-image failure is obtained, i.e. mobile terminal can not carry out secret protection according to face feature.In other optimal enforcement examples, move Dynamic terminal from contact list information when obtaining the failure of contact person's face feature, from the third party's communication software being locally stored In contact data, such as third party's social network services（Social Networking Services, abbreviation SNS）, microblogging, Wechat obtains the face characteristic of the object contact person.Alternatively, network acquisition, which can also be used, in mobile terminal is stored in remote service The face characteristic of object contact person in device.In addition, when mobile terminal obtains face characteristic failure through the above way, can also carry Show that user takes pictures to the object contact person using camera, or prompt user schemes the face of the object contact person As being uploaded under local preset path, mobile terminal after the completion of user uploads, go forward side by side from preset path by acquisition face image Row identification is to obtain face feature.Therefore the specific steps for acquiring face characteristic to mobile terminal at this do not define.

If the feature data types of required acquisition include voiceprint, mobile terminal monitors making a return journey for object contact person Electricity judges whether the call meets preset voiceprint extraction condition when user and object contact person converse next time, For example, call environment level of noise whether is less than default level of noise or whether the duration of call is more than preset duration value, if so, Then meet voiceprint extraction condition.The default voiceprint extraction condition can be configured by user or is arranged by system default. When the call meets preset voiceprint extraction condition, mobile terminal acquires the voiceprint of object contact person as characteristic According to, and cease listening for the incoming/sending call of object contact person.It is described call do not meet default voiceprint extraction condition when, mobile terminal after The continuous incoming/sending call for monitoring object contact person, and when user and object contact person are conversed next time, judge that the call is It is no to meet preset voiceprint extraction condition, when the call listened to meets the voiceprint extraction condition, mobile terminal acquisition The voiceprint of object contact person ceases listening for the incoming/sending call of the object contact person as characteristic.It needs to illustrate Be, before mobile terminal collects object contact person voiceprint, mobile terminal can not according to the voiceprint of contact person into Row secret protection.Certainly, in other embodiments, mobile terminal prompts user to utilize wheat in user setting secret protection The voice-input devices such as gram wind obtain the sound of object contact person, to acquire the voiceprint of object contact person.Alternatively, mobile whole End prompt user will only include that the audio file of sound of object contact person is uploaded under local preset path, mobile terminal with After the completion of family uploads, from the voiceprint obtained in preset path in audio file.

Step S203：When the name that the classification of the characteristic is object contact person, and the data type belongs to text When word info class, mobile terminal searches for the name comprising object contact person in local and belongs to the word letter of the data type Breath is used as target private data.

For example, when the target private data that user protects in advance is the communication information, i.e. acquisition for mobile terminal object contact person Name goes out in title or content the communication information for including object contact person name, Tathagata in local search as characteristic It is recorded from the message registration and short message of object contact person etc., using as target private data.

Step S204：When the face feature that the classification of the characteristic is the object contact person, and the data class When type belongs to image class, mobile terminal utilizes face recognition technology, is searched for containing the face feature in local and belongs to institute The image data of data type is stated as the target private data.

For example, when the target private data that user protects in advance is image, the face of acquisition for mobile terminal object contact person Feature is as characteristic, using face recognition technology, goes out the image of the face feature containing object contact person in local search Data, using as target private data.

Wherein, recognition of face is to compare the technology that face visual signature information carries out identity discriminating using analysis.Specifically, it moves Dynamic terminal-pair local image carries out Face datection, wherein mobile terminal is using reference template method, face rule method, sample study The one of which of method, complexion model method, sub-face of feature method etc. in summary several carries out Face datection.Mobile terminal is examined It measures using feature vector method, face line template etc. that the face detected and mobile terminal is collected after the face in image Contact person's face feature carries out face comparison, if the face detected is matched with contact person's face feature, it is determined that institute It is target private data to state image.

Above-mentioned human face detection tech is illustrated:1）Reference template method：Mobile terminal designs one or several marks first Then the template of quasi- face calculates the matching degree between the sample and standard form of test acquisition, and is judged by threshold value With the presence or absence of face；2）Face rule method：Since there is face certain structure distribution feature, mobile terminal to extract these features Corresponding rule is generated to judge whether test sample includes face；3）Sample learning method：Use artificial god in pattern-recognition Method through network, mobile terminal is by opposite as sample sets and non-face as the study of sample sets generates grader；4）Colour of skin mould Type method：Mobile terminal is distributed the rule of Relatively centralized to be detected according to the looks colour of skin in color space；5）Sub-face of feature Method：All image surface set are considered as an image surface subspace by mobile terminal, and based on detection sample and its projection between sub-aperture The distance between judge whether image surface.Since face detection is the prior art, specific implementation please refers to related face Portion's identification technology data, does not elaborate herein.

Step S205：When the voiceprint that the classification of the characteristic is the object contact person, and the data class When type belongs to audio class, mobile terminal utilizes sound groove recognition technology in e, is searched for containing the voiceprint in local and belongs to institute The audio data of data type is stated as target private data.

For example, when the target private data that user protects in advance is acoustic information, acquisition for mobile terminal object contact person Voiceprint utilizes sound groove recognition technology in e, goes out containing the object contact person in local search as characteristic, mobile terminal The audio data of voiceprint, using as target private data.

Specifically, Application on Voiceprint Recognition refers to according to human physiology is spoken in reflection in speech waveform and behavioural characteristic is that speaker is peculiar Speech parameter, speaker is identified according to the speech parameter.The sound in audio in acquisition for mobile terminal local, extraction Vocal print feature compares the vocal print feature with the contact person's voiceprint acquired before, if the vocal print feature and contact person Voiceprint matches, then using the audio data as private data.Since sound groove recognition technology in e is the prior art, specific implementation Related sound groove recognition technology in e data is please referred to, is not elaborated herein.

Step S206：Mobile terminal is encrypted, hides or is isolated to the target private data.

Mobile terminal is matched to what is searched out with the characteristic got, and the target for belonging to pre- protection data type is hidden Private data carry out data encryption, hide or be isolated, to carry out privacy secrecy setting to target private data.Optimally, mobile Terminal shows the target private data, and prompt the user whether after searching out target private data in man-machine interface Secret protection is carried out, when getting determining secret protection instruction input by user, mobile terminal selects user to carry out privacy The target private data of secrecy carries out secret protection.In present embodiment, mobile terminal uses general standard encryption algorithms, such as Target private data is encrypted in the AES128/256 realizations of international standard symmetric encipherment algorithm so that target private data is in Can not read states, and when obtaining password authentification, mobile terminal normally shows the target private data.

In another embodiment, mobile terminal carries out secret protection using concealing technology to target private data.Specifically, The target private data searched out is moved to from original storing directory in default file folder by mobile terminal, and to described pre- If permission is arranged in file or mobile terminal directly carries out the target private data searched out under original storing directory Priority assignation so that permission cannot be pressed from both sides or be directly arranged to all applications in mobile terminal to the default file of the setting permission Target private data access, and guard mode is presented on man-machine interface is shown, needs to check the target in user When private data, carry out password authentification, and password authentification by when, mobile terminal temporarily obtains permission to show the target Private data.

Alternatively, isolation technology can also be used in mobile terminal carries out secret protection to target private data.Specifically, mobile terminal Partial memory area domain is isolated, and the target private data searched out is moved to the storage of isolation from original storing directory Region, wherein the storage region of isolation is the region that cannot access of application in system, user when checking the storage region, Need password authentification.When mobile terminal is multisystem such as double OS systems, also target private data can be isolated to security level In high system environments.Mobile terminal can not access the target privacy in high-level system when in low security level system Data, when entering high security level system environments, the normal display target private data of mobile terminal.

It should be noted that mobile terminal can select above-mentioned secret protection mode by system default, privacy can be also provided Interface is arranged in protected mode, for user's selecting to secret protection mode.In addition, the application mobile terminal is hidden to target The mode that private data carry out secret protection is also not limited to above-mentioned data encryption, hides and be isolated, other protection sides also can be used Formula is not construed as limiting secret protection mode at this.

Step S207：If detecting that new deposit data match with the characteristic and belong to the data type, The data are carried out secrecy setting by mobile terminal.

Mobile terminal to target private data during carrying out secret protection, if detecting that mobile terminal is locally newly deposited Enter data, is then judged whether to match with the characteristic of object contact person to being newly stored in data, and it is hidden whether to belong to target The data type of private data, if being newly stored in data and the contact feature Data Matching and belonging to the data type, Data encryption is carried out using the data as target private data, hides or is isolated.

For example, mobile terminal hides the communication information of object contact person according to user input instruction.Mobile terminal exists During carrying out secret protection, if there is new message registration or short message record, then pass through the characteristic of object contact person Such as name, judge the message registration either short message record whether from the object contact person or the short message content whether Including object contact person name, if it is, the message registration or short message record are hidden.In addition, not fetched having If mobile terminal judges that the missed call or unread short messages are contacted from the target when electric either unread short messages People, then mobile terminal man-machine interface prompt user have missed call or unread short messages when, do not show the caller or come Letter person, and when passing through password authentification, mobile terminal shows the information of missed call or the content of unread short messages.

Step S208：If the encrypted message for receiving user is preset password information, mobile terminal shows the target Private data.
