Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
According to the embodiment of the present invention, a user information delivery method applied to a client is provided, as shown in fig. 1, including step 101, step 102 and step 103.
Step 101: the first application receives a sharing request from a first user.
In some embodiments, the first application includes, but is not limited to, an application including instant messaging functionality; the sharing request includes any request for sharing information, such as a sharing request for sharing information inviting friends to participate in a vote, a sharing request for sharing a photo, and so on.
According to some embodiments of the invention, before step 101, the method further comprises: the first application receives a registration request from a first user, sends the registration request to the server, receives a registration result returned by the server, and correspondingly stores the user identification contained in the registration result and the registration information contained in the registration request; the registration information includes, but is not limited to, a user name, etc.
Further, before step 101, the method further includes: the first application receives a login request from a first user, verifies whether login information in the login request is correct or not according to the stored registration information, if yes, login is successful, and otherwise, login is failed.
Step 102: the first application generates a sharing picture which contains the user identification and is invisible to the user identification according to the sharing content corresponding to the received sharing request and the user identification of the first user, so that the server side can detect the user identification in the sharing picture. The user identifier in the shared picture is almost invisible in visual effect for an ordinary user, that is, the user identifier contained in the shared picture does not affect the visual effect of the shared picture basically. The first application can add the user identifier to the shared picture in multiple modes, and the visual effect of the shared picture is not affected basically.
According to some embodiments of the invention, step 102 comprises:
step A1: the first application generates a content picture according to the sharing content corresponding to the received sharing request;
step A2: the first application acquires a user identifier of a first user;
optionally, the first application searches a corresponding user identifier in a user database according to the login information of the first user; or the first application sends a user identification obtaining request to the server according to the login information of the first user and receives a user identification returned by the server; the login information includes, but is not limited to, a user name, etc.
It should be noted that the execution order of step a1 and step a2 may be interchanged.
Step A3: and the first application generates a sharing picture which contains the user identification and is invisible to the user identification according to the generated content picture and the acquired user identification.
According to some embodiments of the invention, step a3 comprises:
step A3-1: the first application transforms the generated content picture to obtain a first digital image;
according to some embodiments of the present application, step a3-1 may comprise: the first application carries out discrete cosine change on the generated content picture to obtain a first frequency domain matrix, and the first frequency domain matrix is used as a first digital image.
As an example, the upper right portion of the first digital image may be a high frequency sequence, the lower left portion may be a low frequency sequence, and the diagonal portion from the upper left portion to the lower right portion may be a medium frequency sequence.
According to other embodiments of the present application, step a3-1 may include: and the first application carries out color decomposition on the generated content picture to obtain an integer matrix corresponding to red, green and blue one by one, and the obtained integer matrix is used as a first digital image.
Step A3-2: and the first application replaces the preset elements in the first digital image with the acquired user identification to obtain a second digital image.
In some embodiments, the preset elements in the first digital image comprise preset eligible elements. For example, if the first digital image is a frequency domain matrix, the predetermined elements include elements in the frequency domain matrix that conform to a predetermined frequency band.
According to some embodiments of the present application, step a3-2 comprises:
step A3-2-1: and the first application encrypts the acquired user identifier to obtain a user identifier ciphertext.
Specifically, the first application encrypts the obtained user identifier according to a preset encryption algorithm by using a preset key to obtain a user identifier ciphertext.
The encryption algorithm may be set according to the requirement, such as AES, RSA, and the like.
Step A3-2-2: and the first application generates the header information in a preset form according to the length of the user identification ciphertext.
The preset form can be set according to the requirement, for example, the header information is set to be 8 bytes, the first two bytes are preset characters, and the last six bytes are used for representing the length of the user identification ciphertext.
Step A3-2-3: and the first application replaces preset elements in the first digital image with the generated header information and the user identification ciphertext according to a preset storage proportion to obtain a second digital image.
The preset storage proportion can be set according to the requirement; preferably, the preset storage ratio is such that each element in the matrix stores 8 bytes of data.
In some embodiments, when the first digital image is specifically the first frequency domain matrix, the user identification ciphertext is placed behind and next to the header information, and a part of intermediate frequency elements in the first digital image is sequentially replaced according to a mode that 8 bytes correspond to one element, so that a second frequency domain matrix is obtained and serves as the second digital image.
When the first digital image is specifically an integer matrix after color decomposition, an integer matrix corresponding to a preset color (for example, an integer matrix corresponding to red) is selected, a user identification ciphertext is placed behind and next to the header information, part of elements in the selected integer matrix are sequentially replaced according to a mode that 8 bytes correspond to one element, the replaced integer matrix and other integer matrices which are not replaced are synthesized to obtain a transformation matrix, and the transformation matrix is used as a second digital image.
Particularly, when the length of the user identification ciphertext is not an integral multiple of 8 bytes, according to the sequence from left to right, filling zero with a corresponding number after the last byte of the user identification ciphertext, and performing bit padding; for example, if the user identification ciphertext has a length of 68 bytes, then 4 zeros are padded after the last byte.
Furthermore, in the invention, the first application can automatically select the position of the header information in the first digital image according to the length of the user identification ciphertext; the location of the header information may also be preset.
Step A3-4: and the first application generates a sharing picture which contains the user identification and is invisible to the user identification according to the second digital image.
Specifically, when the first digital image is a first frequency domain matrix, the first application converts the second digital image into a time domain to obtain a shared picture which contains a user identifier and is invisible to the user identifier; when the first digital image is an integer matrix after color decomposition, the first application calculates the second digital image and a preset image layer matrix and converts the second digital image and the preset image layer matrix into a sharing image which contains a user identifier and is invisible to the user identifier.
Preferably, the shared picture contains a preset picture identifier, wherein the preset picture identifier can be set according to the requirement, for example, the preset picture identifier is a character or a pattern related to the activity.
It should be noted that, because the replacement of a part of intermediate frequency elements does not substantially affect the display of the visual effect of the picture itself, when the first digital picture is a frequency domain matrix, by replacing a part of intermediate frequency elements thereof, it is achieved that the generated shared picture contains a detectable user identifier and the user identifier is invisible.
Furthermore, partial elements in the integer matrix after color decomposition are replaced, so that the color of the corresponding position in the picture corresponding to the synthesized transformation matrix is changed, and the original color is restored by operating the transformation matrix and the preset layer matrix, and the visual effect display of the picture is basically not influenced, so that the generated shared picture contains detectable user identification and the user identification is invisible.
In the application, the generated content picture is converted to obtain the digital picture in a matrix form, so that part of elements in the digital picture are replaced by the user identification on the premise of not influencing the normal display of the picture, or other transformations are carried out after part of elements in the digital picture are replaced, so that the generated picture can be normally displayed, and the generated sharing picture contains the detectable user identification and is invisible to the user identification. It should be noted that the conversion of the content pictures is not limited to the above conversion method, and all other conversion methods applied to the conversion principle of the present application should be covered within the protection scope of the present application.
Step 103: and sharing the sharing picture to the second application and/or the second user.
Wherein the second application is an application different from the first application, and in some embodiments, the second application comprises an application with a technology communication function; in some embodiments, the second user may have a social relationship with the first user, e.g., the second user is a contact of the first user in the first application, and/or the second user is a contact of the first user in the second application.
Preferably, step 103 further comprises: and the first application receives a picture storage request from the first user and stores the generated shared picture to the album of the device where the first application is located.
Preferably, the sharing the picture to the second application in step 103 includes: the first application calls a sharing program package and shares the sharing picture to the second application; or sharing the shared pictures in the photo album to the second application through the sharing function of the photo album.
More preferably, the first application calls a corresponding sharing program package of the second application according to application information (for example, an application name) of the second application submitted by the first user, and shares the shared picture to the second application; or the first user accesses the photo album of the own device, selects the shared picture in the photo album, and shares the shared picture to the second application through the sharing function of the photo album.
According to some embodiments of the present invention, sharing the shared picture to the second user may include: the first application calls a sharing program package to share the shared picture to the second user; or accessing the album in the equipment through the second application, and sharing the shared pictures in the album to the second user; or sending the stored sharing picture to the second user through the multimedia message.
More preferably, the first application calls a sharing program package of the first application or the second application according to the user information of the second user submitted by the first user, and shares the shared picture to the second user; or the first user accesses the photo album in the second application, selects the shared pictures in the photo album and shares the shared pictures to the second user; or the first user selects the shared pictures in the album and sends the shared pictures to the second user through the multimedia messages.
Therefore, in the embodiment, the user identifier is hidden in the shared picture and can be obtained through detection, so that when the shared picture is shared, not only is the privacy of the user effectively protected, but also the possibility of the blocking of a third-party platform can be reduced.
Example two
According to the embodiment of the present invention, a method for delivering user information applied to a server is provided, as shown in fig. 2, including step 201 and step 202.
Step 201: and the server receives a joining request from the second application and/or the second user, and the server is the server of the first application.
Preferably, when the user of the second application sees the shared picture in the second application, the user sends a join request to the server through the second application; or when the second user receives the sharing picture sent by the multimedia message of the first user, the two-dimension code in the sharing picture is identified or the sharing picture is clicked to carry out page skipping, and a joining request is sent to the server side.
It should be noted that the join request is a generic term of related operations, including joining certain social networks, browsing certain information, participating in certain activities, and the like.
Step 202: the server side obtains the corresponding sharing picture, and detects the obtained sharing picture to obtain the user identification of the first user of the first application.
According to some embodiments of the present invention, when the second user receives the shared picture, the method further comprises saving the shared picture to an album of the device;
correspondingly, the server side obtains the corresponding sharing picture, including: the server returns the submitted picture information and receives the sharing picture uploaded by the second application and/or the second user; or the server accesses the photo album of the corresponding equipment to acquire the shared pictures in the photo album.
Further, the server accesses the photo album of the corresponding device to obtain the shared pictures in the photo album, which specifically includes: and the server accesses the photo album of the corresponding equipment and searches the shared picture in the photo album according to the preset picture identification.
The preset picture identification can be set according to the requirement, for example, characters or patterns related to activities.
Further, when the server obtains the corresponding shared picture, specifically, when the server receives the shared picture uploaded by the second application and/or the second user, before analyzing the obtained shared picture in step 202, the method further includes: and judging whether the received sharing picture is effective or not, if so, continuing, and otherwise, returning joining failure information.
For example, whether the received picture contains a preset picture identifier is judged, if yes, the received shared picture is judged to be valid, and if not, the received shared picture is judged to be invalid.
According to some embodiments of the present invention, detecting the obtained shared picture to obtain the user identifier of the first user of the first application includes:
step B1: and transforming the acquired sharing picture to obtain a second digital image.
Generally, the transformation performed on the acquired shared picture is an inverse transformation of a transformation method adopted when the first application transforms the second digital image into the shared picture.
For example, discrete cosine change is performed on the obtained shared picture to obtain a second frequency domain matrix, and the second frequency domain matrix is used as a digital image.
Or, the obtained shared picture and a preset layer matrix are operated to obtain a transformation matrix, and the transformation matrix is used as a second digital image.
Step B2: the second digital image is detected to obtain a user identification of the first user of the first application.
According to some embodiments of the present application, step B2 includes:
step B2-1: header information in a preset form in the second digital image is identified.
When the second digital image is a second frequency domain matrix, identifying header information in a preset form in the second digital image according to preset characters; or identifying the preset form of header information in the second digital image according to the position of the preset header information.
When the second digital image is a transformation matrix, performing color decomposition on the image corresponding to the transformation matrix to obtain an integer matrix corresponding to red, green and blue one by one, selecting an integer matrix corresponding to a preset color (for example, an integer matrix corresponding to red), and identifying header information in a preset form in the selected integer matrix according to preset characters; or, according to the preset head information position, identifying the head information in the preset form in the selected integer matrix.
Step B2-2: and analyzing the identified header information to obtain the length of the user identification ciphertext.
Specifically, according to the preset form of the header information, data on the corresponding byte in the header information is read, and the length of the user identification ciphertext is obtained.
For example, the preset header information is 8 bytes, where the first two bytes are preset characters, and the last six bytes are used to indicate the length of the user identification ciphertext, and then the data in the last six bytes of the header information are read to obtain the length of the user identification ciphertext.
Step B2-3: and reading data behind the header information to obtain the user identification ciphertext according to the length of the obtained user identification ciphertext and a preset storage proportion.
The preset storage proportion can be set according to the requirement; for example, the preset scale stores 8 bytes of data for each element in the matrix.
Particularly, when the length of the user identification ciphertext obtained by analysis is not an integral multiple of 8 bytes, discarding the padding zero on the corresponding byte in the last element for storing the user identification ciphertext; for example, if the parsed user identification ciphertext has a length of 68 bytes, zeros are discarded from the last four bytes of the last element of the user identification ciphertext.
Step B2-4: and decrypting the obtained user identification ciphertext to obtain the user identification.
Specifically, according to a preset decryption algorithm, the obtained user identifier is decrypted by using a preset secret key to obtain a user identifier ciphertext.
The preset decryption algorithm can be set according to the requirement.
In this embodiment, the server can obtain the invisible user identifier in the surface of the shared picture by detecting the obtained shared picture, so that adverse effects on business operations such as data analysis and statistics based on the user identifier are not caused.
EXAMPLE III
According to an embodiment of the present invention, a method for transferring user information is provided, as shown in fig. 3, including:
step 301: the first application receives a sharing request from a first user.
For example, a first application receives a share request from a first user inviting a friend to participate in a voting activity.
Step 302: and the first application generates a sharing picture which contains the user identification and is invisible to the user identification according to the sharing content corresponding to the received sharing request and the user identification of the first user.
The implementation method of this step is the same as the implementation method of step 102 in the first embodiment, and is not described herein again.
Preferably, step 302 is followed by: and the first application receives a picture storage request from the first user and stores the generated shared picture to the album of the device where the first application is located.
Step 303: sharing the generated sharing picture to a second application and/or a second user;
for example, a first user of a first application shares a shared picture to a second application in advance, and when the first application receives application information of the second application submitted by the first user, a sharing program package of the second application is called to share the shared picture to the second application;
for another example, a first user of a first application shares a shared picture to a second user, and the second user is a contact of the first user in the first application and a contact of the first user in the second application; the sharing program package of the first application or the second application can be called through the first application, and the shared picture is analyzed to the second user; the photo album can also be accessed in the second application, and shared pictures in the photo album are shared to the second user; and the sharing picture can be sent to a second user through the multimedia message.
Step 304: when the server receives a joining request from a second application and/or a second user, acquiring a corresponding sharing picture, and detecting the acquired sharing picture to obtain a user identifier of the first user.
For example, the second user sees a shared picture shared by the first user in the second application, and sends a join request to the server through the second application; the server returns the submitted picture information, receives the sharing picture uploaded by the second application, and detects the received sharing picture to obtain the user identification of the first user.
If the second user receives the sharing picture sent by the first user through the multimedia message, the two-dimension code in the sharing picture is identified and the second user jumps to the corresponding page, so that a joining request is sent to the server; and the server accesses the photo album of the second user equipment, searches the shared picture in the photo album according to the preset active pattern, and detects the searched shared picture to obtain the user identification of the first user.
