Referring to fig. 1, a flowchart illustrating steps of an image encryption method according to a first embodiment of the present invention is shown.
The image encryption method of the embodiment of the invention comprises the following steps:
step 101: and determining the area to be hidden in the image according to the selected operation of the user on the image.
The user can demarcate an area to be hidden in the image through fingers; the user can also select a template graph, and the area to be hidden is selected in the image through the template graph. The template image may be any suitable shape, such as triangular, rectangular, circular, etc.
Step 102: generating a bar code for the area to be hidden.
The bar code carries a unique identifier of the area to be hidden and an access link corresponding to the authentication information input interface. The unique identifier may be located to a certain hidden area in a certain image.
When generating the bar code for the area to be hidden, the user inputs authentication information, and when other subsequent users want to check the hidden area, the authentication information needs to be input for authentication, the authentication information corresponds to an authentication information input interface, and the authentication information input interface corresponds to an access link. Before the user inputs the authentication information, the authentication mode can be selected according to actual requirements, different authentication modes correspond to different authentication information input interfaces, and accordingly, the specific authenticated parameter items are different.
The authentication method may be any one of the following: answer authentication mode, payment authentication mode, biological characteristic authentication mode and real-time authentication mode. The specific authentication parameters and the specific authentication methods corresponding to the various authentication methods may refer to related technologies, which is not specifically limited in the embodiment of the present invention.
Step 103: the bar code is overlaid on the area to be concealed.
The barcode may be a one-dimensional barcode or a two-dimensional barcode. The bar code is covered on the area to be hidden, the browsing authority of the image is limited, and at the moment, no matter the image is distributed on the network or stored in the local of the mobile terminal, a browser cannot browse the complete image.
In a specific implementation process, one image is not limited to be hidden only in one region to be hidden, and two or more regions can be hidden. When two or more regions need to be hidden, the steps 101 to 103 are executed in a loop, so that multiple regions can be hidden.
The image encryption method provided by the embodiment of the invention generates the bar code carrying the unique identifier of the hidden area and the access link for the area to be hidden in the image, and covers the bar code on the area to be hidden in the image so as to realize the encryption of the image. Therefore, the image encryption method provided by the embodiment of the invention realizes the management of the browsing authority of the single image by encrypting the partial area in the single image, and has stronger flexibility.
Example two
Referring to fig. 2, a flowchart illustrating steps of an image encryption method according to a second embodiment of the present invention is shown.
The image encryption method of the embodiment of the invention specifically comprises the following steps:
step 201: and determining the area to be hidden in the image according to the selected operation of the user on the image.
For example: the image contains an object A, B, and the user can select the object a in the image because the user restricts the browsing authority of the object a in advance.
After the area to be hidden is determined, a bar code needs to be generated for the area to be hidden, and when the bar code is generated: firstly, generating a unique identifier for an area to be hidden; secondly, receiving authentication information input by a user in an authentication information input interface, and establishing a binding relationship between the authentication information and the unique identifier; and finally, generating the bar code according to the access link and the unique identifier. Specifically, the process of generating the unique identifier for the area to be hidden is shown in steps 202 to 203, the authentication information input by the user in the authentication information input interface is received, and the process of establishing the binding relationship between the authentication information and the unique identifier is shown in steps 204 to 207.
Step 202: the information of the image and/or the information of the area to be hidden is converted into a binary data stream.
The information of the image may include, but is not limited to: information such as the name of the image, the image capturing time, and the image size, and preferably, the information of the image may further include: image content information of the area to be hidden. The image content information of the hidden area is used as a part of the information of the image and converted into the binary data stream, and then the unique identifier of the area to be hidden is generated according to the binary data stream, so that the repetition probability of the unique identifier can be reduced.
The information of the region to be hidden may include, but is not limited to: size, shape, position in the image, etc. of the region to be hidden.
In a specific implementation process, only the information of the image can be converted into a binary data stream to generate a unique identifier; or only the information of the area to be hidden can be converted into binary data stream to generate a unique identifier; the two data streams can be converted into binary data streams, and the binary data streams converted by the two data streams are spliced into a binary data stream according to a preset sequence.
The hidden image content information may include, but is not limited to: hidden image grayscale, hidden image color channel histogram.
Step 203: and determining a hash value corresponding to the binary data stream, and determining the hash value as the unique identifier of the area to be hidden.
The specific way of determining the hash value corresponding to the binary data stream may be implemented by referring to related technologies, which is not specifically limited in the embodiment of the present invention. After the unique identifier of the hidden area is generated, a binding relationship between the unique identifier and the authentication information needs to be established, and a process of determining the authentication information is shown in steps 204 to 206.
Step 204: and detecting the selection operation of the user on the authentication mode.
The mobile terminal can provide different authentication mode selection interfaces for users, such as: the user can complete the selection of the authentication mode by clicking the button corresponding to the authentication mode. The authentication method includes but is not limited to: answer authentication mode, payment authentication mode, biological characteristic authentication mode and real-time authentication mode. In the embodiment of the invention, a plurality of authentication modes are provided for the user to select, and the individual requirements of the user can be met.
Step 205: and displaying an authentication information input interface corresponding to the selected authentication mode.
Different authentication modes correspond to different authentication information input interfaces, access connections of different input interfaces are different, and inputtable parameter items contained in the input interfaces are also different.
Step 206: authentication information input by a user is received.
The answer authentication mode is as follows: and filling the question and the answer in an authentication information input interface corresponding to the answer authentication mode by the user.
Biometric authentication method: the user needs to select the biological characteristic information of the person authorized to browse the hidden area, such as fingerprints, irises, faces and the like, in the authentication information input interface corresponding to the biological characteristic authentication mode. The biological characteristic information can be uploaded to a server in advance and acquired from the server when the biological characteristic information needs to be selected; biometric information of a person authorized to view the hidden area may also be obtained on-site.
And (3) payment authentication mode: and the user sets the payment mode and the amount of money in the authentication information input interface corresponding to the payment authentication mode. The payment mode can be red envelope payment, Paibao payment and the like.
A real-time authentication mode: the user inputs the contact way of the mobile terminal in the authentication information input interface corresponding to the real-time authentication way, so that when a browser scans the code during image decryption, the server sends prompt information to the mobile terminal of the user according to the contact way to prompt the user whether to authorize the browser, and the user can determine whether to authorize the browser to browse the hidden area according to the browser information provided by the server.
Step 207: and uploading the authentication information and the unique identifier to a server to establish a binding relationship between the authentication information and the unique identifier.
In the embodiment of the present invention, the binding relationship between the authentication information and the unique identifier is established by the server as an example, but the embodiment is not limited to this, and the binding relationship between the authentication information and the unique identifier may also be established by the mobile terminal, and the binding relationship between the authentication information and the unique identifier is stored at the mobile terminal side.
Step 208: the barcode is generated from the access link and the unique identifier.
The generated bar code carries an access link of the authentication information input interface and a unique identifier of the area to be hidden.
Step 209: the bar code is overlaid on the area to be concealed.
The bar code is covered on the area to be hidden, the browsing authority of the image is limited, and at the moment, no matter the image is distributed on the network or stored in the local of the mobile terminal, a browser cannot browse the complete image.
Step 201 to step 209 are processes of encrypting a region to be hidden in an image, and if other regions in the image need to be hidden in a specific implementation process, the steps 201 to step 209 may be returned to, and after all regions in the image that need to be hidden are encrypted, the encryption setting for the image may be exited.
The image encryption method provided by the embodiment of the invention generates the unique identifier for the area to be hidden in the image, binds the authentication information for the unique identifier, generates the bar code according to the access link corresponding to the authentication information and the generated unique identifier, and covers the bar code on the area to be hidden in the image so as to realize the encryption of the image. Therefore, the image encryption method provided by the embodiment of the invention realizes the management of the browsing authority of the single image by encrypting the partial area in the single image, and has stronger flexibility.
EXAMPLE III

The image decryption method of the embodiment of the invention comprises the following steps:
step 301: and scanning the bar code covered on the hidden area in the image to acquire the unique identifier and the access link.
When scanning the bar code, the bar code can be scanned by long press. Because the bar code carries the unique identifier of the hidden area and the access link of the authentication information input interface, the unique identifier and the access link can be obtained after the bar code is successfully scanned.
Wherein the unique identifier is used to locate a specific hidden area in a specific image. And after the access link is scanned, the authentication information input interface corresponding to the link can be accessed by directly accessing the link.
Step 302: and displaying an authentication information input interface corresponding to the access link.
For example, if the authentication mode adopted by the hidden area during encryption is an answer authentication mode, an authentication information input interface corresponding to the answer authentication mode is displayed.
Step 303: authentication information input by a user is received.
Step 304: and determining whether the user has the hidden area viewing permission or not according to the authentication information and the unique identifier.
When the hidden area is encrypted, the corresponding relation between the unique identifier corresponding to the hidden area and the authentication information is established, so that when the image is decrypted, if the authentication information input by the user is the same as the authentication information set during encryption, the user is determined to have the hidden area viewing permission.
For example: when the X object in the image A is encrypted, the binding relationship between the unique identifier B and the authentication information C is established. When the X object of the image A is decrypted, the obtained unique identifier is B, and if the authentication information input by the user is C, the user can be determined to have the viewing permission of the hidden area.
In a specific implementation process, the server may determine whether the user has a hidden area viewing right according to the authentication information and the access link, specifically:
the mobile terminal uploads the authentication information and the unique identifier to the server, and the server judges whether the authentication information and the unique identifier have a binding relationship; if yes, determining that the user has the hidden area viewing permission; if not, determining that the user has no hidden area viewing authority;
certainly, the present invention is not limited to this, if the image is encrypted locally at the mobile terminal, the mobile terminal may also determine whether the user has the hidden area viewing right according to the authentication information and the access link, specifically:
judging whether the mobile terminal side stores the binding relationship between the authentication information and the unique identifier; if yes, determining that the user has the hidden area viewing permission; if not, determining that the user has no hidden area viewing permission.
Step 305: and determining whether to hide the bar code according to the judgment result.
When the judgment result shows that the user has the hidden area viewing right, the hidden barcode user can browse the image part hidden in the hidden area; and when the judgment result shows that the user has no hidden area viewing right, still displaying the image part hidden by the hidden area, which cannot be browsed by the bar code user.
According to the image decryption method provided by the embodiment of the invention, when a user browses the hidden area in the image in advance aiming at the image which is encrypted independently, the bar code covered on the hidden area is scanned, the authentication information is input for authority authentication, and when the authentication is passed, the bar code covered on the hidden area can enable the hidden user to browse the complete image. Therefore, the image decryption method provided by the embodiment of the invention can decrypt the individually encrypted image, so that a user with browsing authority can browse the complete image.

Step 407: and the second mobile terminal displays an authentication information input interface corresponding to the access link.
Different access links are specifically arranged on different authentication information input interfaces, and the corresponding authentication information input interface can be opened to be displayed to a second user by accessing the corresponding access link.
Step 408: the second mobile terminal receives authentication information input by the second user.
Step 409: the second mobile terminal uploads the authentication information and the unique identifier to the server, and the server judges whether the authentication information and the unique identifier have a binding relationship.
If the binding relationship between the authentication information uploaded by the second mobile terminal and the unique identifier exists in the server, it is indicated that the authentication information input by the second user can be verified, and the second user has the right to view the hidden area. Otherwise, the second user does not have the right to view the hidden area.
Step 410: and the server determines whether to hide the bar code according to the judgment result.
