According to an example of this embodiment, when the information related to a contact includes a screenshot of a chat record with the contact, the screenshot may be associated with a corresponding private contact by:

identifying a contact in the interface of the mobile terminal when a screenshot command is received;

and when the identified contact person is a preset private contact person, judging that the intercepted picture is information related to the private contact person.

When the information related to the contact includes the received data sent by the contact, whether the sent data is the information related to the private contact can be judged by the following modes:

and when the data sent by the contact person is received, judging whether the contact person sending the data is a private contact person, if so, judging that the data is information related to the private contact person.

The secondary password may be a fingerprint password, an iris feature password, or a facial feature information password of the user.

And S303, when the primary password of the user passes the verification but the secondary password of the user does not pass the verification, acquiring the level of the contact person.

In this embodiment, the contact belongs to a hierarchy that includes a hierarchy of private contacts and a hierarchy of normal contacts.

According to an example of the embodiment, it is required to classify the contact persons as common contact persons or private contact persons in advance, in this embodiment, the user may set the private label to the contact person needing to be classified, all the contact persons with the private labels set are classified as private contact persons, and all the contact persons without the private labels set are automatically classified as common contact persons.

S304, when the obtained level is a private contact, hiding the information related to the contact.

According to an example of this embodiment, the processing manner corresponding to the information related to the private contact is not limited to hiding the corresponding information, but may also be processed in an encrypted manner, and the encrypted file is stored in a preset folder.

In one embodiment thereof, the method further comprises:

According to an example of this embodiment, the method further comprises:

when the primary password passes the verification, verifying the secondary password at preset time intervals;

According to an example of the embodiment, taking a contact displayed in an address book as an example, the time after the contact represents the time of last contact with the contact, wherein the contact "king" and "liuxia" are preset private contacts, fig. 5 is a schematic view of an interface use scenario according to another embodiment of the present invention, when the secondary password is verified, all contacts are displayed, and when the secondary password is verified again but the secondary password is not verified, the private contacts "king" and "liuxia" are automatically hidden as shown in fig. 6.

In this embodiment, the preset time period may be one minute, and the above-mentioned manner of verifying the secondary password in real time may better ensure that when a user of the mobile terminal uses the mobile terminal alternately among different users, the user can quickly identify whether the user is the owner of the mobile terminal, so as to protect the privacy contact of the user to the maximum extent.

In the embodiment, by setting the first-level password and the second-level password, when a viewing instruction of information related to the contact is received, whether the first-level password and the second-level password are verified, if the first-level password and the second-level password are verified, all information related to the contact is opened to the user, if the first-level password and the second-level password are verified, all information related to the contact is hidden in the information related to the private contact, the identity of the user is authenticated through the double passwords, when the first-level password is verified, the user is shown to have the authority of using the mobile terminal, when the second-level password is verified, the user is shown to be the owner, only when the user is determined to be the owner, the information related to all the contacts is opened, the information related to the private contact can be better protected, and the privacy of the user is better protected.

Fig. 7 is a flowchart of a method for protecting privacy of a contact according to another embodiment of the present invention, and the method for protecting privacy of a contact according to another embodiment of the present invention is described in detail below with reference to fig. 7, as shown in fig. 7, the method includes steps S301, S303, and S304, the secondary password includes biometric information of a user, and the step S302 further includes:

s701, verifying the primary password of the user.

The primary password is a password input by a user on an unlocking interface, and may be a numeric password, an alphabetic password, a combined password of numbers and letters, a fingerprint password, an iris password, a facial feature information password, and the like, when the primary password passes verification, it indicates that the user has the authority to use the mobile terminal, fig. 4 is a schematic view of an interface use scene according to an embodiment of the present invention, and a use scene for verifying the primary password is shown in fig. 4.

And S702, if the primary password passes the verification, acquiring the biological characteristic information of the user in a hidden mode.

In this embodiment, the secondary password is limited to the biometric information password of the user, and when the secondary password is also verified, it indicates that the user is the owner.

Fingerprints have become almost the pronoun of biometric identification due to their lifetime invariance, uniqueness and convenience. The fingerprint refers to lines generated by convex and concave unevenness on the front skin at the tail end of a human finger. The lines are regularly arranged to form different line types. The starting point, the ending point, the combination point and the bifurcation point of the lines are called minutiae points of the fingerprint. Fingerprint identification refers to identification by comparing minutiae of different fingerprints. Fingerprint identification technology relates to a plurality of subjects such as image processing, pattern recognition, computer vision, mathematical morphology, wavelet analysis and the like. The fingerprints of each person are different, namely the fingerprints are obviously different among the ten fingers of the same person, so that the fingerprints can be used for identity authentication. Because the directions of each time of stamping are not completely the same, different force points can bring different degrees of deformation, a large number of fuzzy fingerprints exist, and the key of the fingerprint identification technology is how to correctly extract the characteristics and realize correct matching. At present, a relatively mature technology is used for comparing fingerprints of users to judge whether the users are the users themselves.

The iris recognition technology is based on the identification of the iris in the eye, and the structure of the eye of a person consists of a sclera, the iris, a pupil lens, a retina and the like. The iris is an annular segment between the black pupil and the white sclera containing many details characteristic of interlaced spots, filaments, coronaries, stripes, crypts, etc. And the iris will remain unchanged throughout life span after it is formed during the fetal development stage. These features determine the uniqueness of the iris features and also the uniqueness of the identification. Therefore, the iris characteristics of the eyes can be used as the identification target of each person, and the iris can also be used for determining whether the person is the owner.

Facial feature information recognition, also called face recognition, is a biometric technology that performs identification based on facial feature information of a person. A series of related technologies, also commonly called face recognition and face recognition, are used to capture an image or video stream containing a face with a camera or a video camera, automatically detect and track the face in the image, and then perform face recognition on the detected face.

The current face recognition technology is a multi-light source face recognition technology based on active near-infrared images. The method can overcome the influence of light change, has excellent recognition performance, and has overall system performance exceeding that of three-dimensional image face recognition in the aspects of precision, stability and speed. The technology is rapidly developed in two or three years, and the face recognition technology gradually becomes practical.

The human face is inherent like other biological characteristics (fingerprints, irises and the like) of a human body, the uniqueness and the good characteristic that the human face is not easy to copy provide necessary premise for identity identification, and compared with other types of biological identification, the human face identification has the following characteristics:

optional characteristics: the user does not need to be specially matched with face acquisition equipment, and can almost acquire a face image in an unconscious state, and the sampling mode is not mandatory;

non-contact property: the user can obtain the face image without directly contacting with the equipment;

concurrency: the method can be used for sorting, judging and identifying a plurality of faces in an actual application scene;

in addition, the visual characteristics are also met: the characteristic of 'people can be identified by the appearance', and the characteristics of simple operation, visual result, good concealment and the like.

And S703, matching the acquired biological characteristic information with pre-stored biological characteristic information, if the matching is successful, judging that the secondary password passes the verification, otherwise, judging that the secondary password fails the verification.

Fig. 5 is a schematic view of an interface usage scenario according to another embodiment of the present invention, and fig. 6 is a schematic view of an interface usage scenario according to another embodiment of the present invention, taking a contact shown in an address book as an example, a time after the contact indicates a time of last contact with the contact, where the contact "king" and "liuxia" are preset private contacts, when the secondary password authentication is not passed, the displayed interface scenario is shown in fig. 6, the private contacts "king" and "liuxia" are automatically hidden, and when the secondary password authentication is passed, the displayed interface scenario is shown in fig. 5, and all contact information is displayed.

In this embodiment, the user may set a private tag to the contact to be kept secret, all the contacts with the private tags are classified as private contacts, and all the contacts without the private tags are automatically classified as normal contacts.

In one embodiment, a privacy tag set for a private contact by a user is not displayed in a display interface of the contact, and the privacy tag only prompts in a setting item.
