Refer to Fig. 2, Fig. 2 is the process flow diagram that the application realizes another embodiment of method for secret protection.In present embodiment, realize method for secret protection and comprise the following steps:
Step S201: mobile terminal, according to user input instruction, obtains the data type of the target private data of pre-containment objective contact person.
Mobile terminal provides interface different types of data being arranged to secret protection.When user arranges the instruction of secret protection by described interface input at least one data type; the contact person that user chooses by mobile terminal is as pre-containment objective contact person; and according to the instruction that user inputs; obtain the data type of the target private data of described object contact person, such as image type, Word message type, audio types, video type etc.
Particularly, mobile terminal provides interface different types of data being arranged to secret protection in man-machine interface, arranges secret protection as comprised to the communication information, image information, acoustic information, video information, all information etc.Accordingly, get user input to object contact person arrange the communication information protection instruction time, the Word message types such as acquisition for mobile terminal message registration, note are as the data type of target private data.Get user input to object contact person arrange image information protection instruction time, acquisition for mobile terminal image type is as the data type of target private data.Get user input to object contact person arrange acoustic information protection instruction time, acquisition for mobile terminal audio types is as the data type of target private data.Get user's input the instruction of video information protection is arranged to object contact person time, acquisition for mobile terminal image and audio types are as the data type of target private data.Get user input the instruction of all information protection is arranged to object contact person time; namely to all information relevant with described object contact person in this locality; as message registration, short breath, p.m.entry, calendar, image, audio frequency, video etc. carry out secret protection, all Word messages of acquisition for mobile terminal, image, audio types are as the data type of target private data.
Step S202: the characteristic of object contact person described in acquisition for mobile terminal.
Mobile terminal provides the interface of the characteristic gathering object contact person in advance, user by described interface arrange in advance acquisition characteristics data time, mobile terminal gather from the information of object contact person the name of object contact person, face feature, voiceprint at least one in order to identify the private data of object contact person, and to be kept in the preset path of mobile terminal as characteristic.Mobile terminal is when obtaining user and inputting secret protection instruction; judge whether prestore described characteristic in described preset path; if had; then mobile terminal directly obtain described in the characteristic that prestores; if no, then mobile terminal carries out instantaneous acquiring to the characteristic of described object contact person.Certainly, in other embodiments, mobile terminal also can be set to, when obtaining user and inputting secret protection instruction, directly carry out instantaneous acquiring to the characteristic of described object contact person.
Carry out collection to mobile terminal to the characteristic of described object contact person to be specifically described, mobile terminal gather the name of object contact person, face-image, voiceprint at least one as characteristic, wherein, the characteristic gathered and target private data type matching, to identify described target private data.Such as, if described data type comprises Word message type, then at least gather object contact person name as characteristic, if described data type comprises image class, then at least gather the face feature of object contact person as characteristic, if described data type comprises audio class, then at least obtain the voiceprint of object contact person as characteristic.Certainly, if described data type is image class or audio class, mobile terminal also can gather the name of object contact person as characteristic, to make to search out image class or audio related data that title comprises described object contact person name.It should be noted that, in other embodiments, the interface that the feature data types of described collection also can be provided by mobile terminal by user is arranged, therefore the application does not do concrete restriction to the collection of feature data types.
Further particularly, when carrying out acquisition characteristics data, if the type of the characteristic of required collection comprises name, then mobile terminal gathers the name information of described object contact person as characteristic from contact list information.
If the feature data types of required collection comprises face feature, then mobile terminal obtains the personal images of object contact person and carries out Face datection from contact list information, if described personal images accurately can obtain face characteristic, then from described personal images, obtain the characteristic of face characteristic as object contact person.If personal images can not accurately obtain the personal images that cannot get object contact person in face characteristic or contact list information, mobile terminal then points out user to obtain face-image failure, and namely mobile terminal cannot carry out secret protection according to face feature.In other optimal enforcement examples, mobile terminal is when obtaining the failure of contact person's face feature from contact list information, from the contact data of third party's communication software of this locality storage, as third party's social network services (Social Networking Services, be called for short SNS), microblogging, micro-letter, obtain the face characteristic of described object contact person.Or mobile terminal also can utilize Network Capture to be stored in the face characteristic of the object contact person in remote server.In addition, when mobile terminal obtains face characteristic failure by the way, also user can be pointed out to utilize camera to take pictures to described object contact person, or under the face image of described object contact person is uploaded to local preset path by prompting user, mobile terminal, after user has uploaded, obtains face image and carries out identifying to obtain face feature from preset path.Therefore at this, restriction is not made to the concrete steps that mobile terminal gathers face characteristic.
If the feature data types of required collection comprises voiceprint, then mobile terminal monitors the incoming/sending call of object contact person, when user and object contact person once converse, judge whether described call meets default voiceprint extraction condition, such as, whether call environment level of noise is less than default level of noise, or whether the duration of call is greater than preset duration value, if so, then voiceprint extraction condition is met.Described default voiceprint extraction condition can be undertaken arranging or being arranged by system default by user.When described call meets default voiceprint extraction condition, mobile terminal gathers the voiceprint of object contact person as characteristic, and stops the incoming/sending call monitoring object contact person.When described call does not meet default voiceprint extraction condition, mobile terminal continues the incoming/sending call monitoring object contact person, and when once conversing on user and object contact person carry out, judge whether described call meets default voiceprint extraction condition, until when the call listened to meets described voiceprint extraction condition, mobile terminal gathers the voiceprint of object contact person as characteristic, and stops the incoming/sending call monitoring described object contact person.It should be noted that, before mobile terminal collects object contact person voiceprint, mobile terminal cannot carry out secret protection according to the voiceprint of contact person.Certainly, in other embodiments, mobile terminal is when user arranges secret protection, and prompting user utilizes the voice-input devices such as microphone to obtain the sound of object contact person, to gather the voiceprint of object contact person.Or under the audio file of the sound only comprising object contact person is uploaded to local preset path by mobile terminal prompting user, mobile terminal, after user has uploaded, obtains the voiceprint in audio file from preset path.
Step S203: when the classification of described characteristic is the name of object contact person, and described data type is when belonging to Word message class, mobile terminal in this locality search package containing the name of object contact person and the Word message belonging to described data type as target private data.
Such as; when the target private data that user protects in advance is the communication information; namely acquisition for mobile terminal object contact person name is as characteristic; go out to comprise in title or content the communication information of object contact person name at local search; as message registration and note record etc. from object contact person, using as target private data.
Step S204: when the classification of described characteristic is the face feature of described object contact person, and described data type is when belonging to image class, mobile terminal utilizes face recognition technology, in this locality search containing described face feature and the view data belonging to described data type as described target private data.
Such as; when the target private data that user protects in advance is image, the face feature of acquisition for mobile terminal object contact person, as characteristic, utilizes face recognition technology; the view data of the face feature containing object contact person is gone out, using as target private data at local search.
Wherein, recognition of face is the technology utilizing com-parison and analysis face visual signature information to carry out identity verify.Specifically, mobile terminal carries out Face datection to local image, and wherein, mobile terminal adopts the wherein a kind of of reference template method, face rule method, sample learning method, complexion model method, feature sub-face method etc. or comprehensively above-mentionedly severally carries out Face datection.Mobile terminal utilizes feature vector method, face line template etc. the face detected and mobile terminal to be collected contact person's face feature after the face in image being detected carries out face contrast, if the face detected mates with described contact person's face feature, then determine that described image is target private data.
Above-mentioned human face detection tech is described: 1) reference template method: first mobile terminal designs the template of or several standard faces, then calculate the matching degree between the sample of test collection and standard form, and judge whether to there is face by threshold value; 2) face rule method: because face has certain structure distribution feature, mobile terminal extracts these features and generates corresponding rule to judge whether test sample comprises face; 3) sample learning method: the method namely adopting artificial neural network in pattern-recognition, mobile terminal produces sorter as sample sets and non-face as the study of sample sets by opposite; 4) complexion model method: mobile terminal detects according to distribute in the color space rule of Relatively centralized of the looks colours of skin; 5) feature sub-face method: all image surface set are considered as an image surface subspace by mobile terminal, and whether there is image surface based on the Distance Judgment detected between sample and its projection between sub-aperture.Because face detection is prior art, its specific implementation please refer to relevant face detection data, does not elaborate at this.
Step S205: when the classification of described characteristic is the voiceprint of described object contact person, and described data type is when belonging to audio class, mobile terminal utilizes sound groove recognition technology in e, in this locality search containing described voiceprint and the voice data belonging to described data type as target private data.
Such as; when the target private data that user protects in advance is acoustic information; the voiceprint of acquisition for mobile terminal object contact person is as characteristic; mobile terminal utilizes sound groove recognition technology in e; the voice data containing described object contact person voiceprint is gone out, using as target private data at local search.
Specifically, Application on Voiceprint Recognition refers to that what speak human physiology and behavioural characteristic according to reflection in speech waveform is the distinctive speech parameter of speaker, identifies speaker according to described speech parameter.Sound in audio frequency in acquisition for mobile terminal this locality, extracts vocal print feature, this vocal print feature and the contact person's voiceprint gathered before is compared, if this vocal print feature is mated with contact person's voiceprint, then using this voice data as private data.Because sound groove recognition technology in e is prior art, its specific implementation please refer to relevant sound groove recognition technology in e data, does not elaborate at this.
Step S206: mobile terminal is encrypted described target private data, hiding or isolation.
