Description

Image processing methods and electronic devices

[0001] This application claims priority to Chinese Patent Application No. 202510390891.4, filed with the State Intellectual Property Office of China on March 28, 2025, entitled "Image Processing Method and Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of image processing, and more particularly to an image processing method and an electronic device. Background Technology

[0003] Image steganography refers to a technique that uses redundant parts or imperceptible changes in an image to hide the information to be transmitted, thereby achieving covert communication. When transmitting data using image steganography, the sending end uses an image steganography algorithm to hide the data to be transmitted into the image, and the receiving end decodes the steganographic data from the image using the same algorithm. Currently, upon receiving a steganographic image, the receiving end decodes the image in an attempt to obtain the steganographic data, resulting in a waste of computing resources, power consumption, and time. Summary of the Invention

[0004] This application provides an image processing method and an electronic device that enables the receiving end to determine whether to decode the received steganographic image, thereby saving the receiving end's computing resources, power consumption, and time when the receiving end determines that it does not need to decode the received steganographic image.

[0005] Firstly, this application provides an image processing method applicable to a receiving end. The method includes: after acquiring a steganographic image, the receiving end acquires the steganographic verification information in the image, and if the verification information passes verification, continues to decode the steganographic information in the steganographic image. In this way, the receiving end can first verify the verification information in the steganographic image before decoding the steganographic information, and then decode the verified steganographic image to obtain the steganographic information. In this application, the verification information enables the receiving end to determine whether to decode the received steganographic image, thereby saving the receiving end's computing resources, power consumption, and time when the receiving end determines that decoding the received steganographic image is unnecessary.

[0006] In one possible implementation, the first steganographic information is the link address information hidden in the first steganographic image. After obtaining the first steganographic information, the receiving end jumps to the link address corresponding to the link address information in the first steganographic image based on the first steganographic information. In this way, the sending end and the receiving end can transmit link address information based on the first steganographic information. For example, when the sending end needs to share a link with the receiving end, the sending end uses an image steganography algorithm to hide the link address information of the webpage in the image, and the receiving end decodes the link address information from the image and jumps to the corresponding link address, thereby completing the sharing of the webpage.

[0007] In one possible implementation, the method further includes: displaying a first prompt message if the first verification information fails, the first prompt message indicating that the first steganatical information in the first steganatical image cannot be decoded. Based on this, the decoding end can avoid continuing to decode the steganatical information in the steganatical image if the first verification information fails, saving the receiving end's computing resources, power consumption, and time. Furthermore, the decoding end can also use the first prompt message to inform the user that it cannot continue decoding the first steganatical information in the first steganatical image.

[0008] In one possible implementation, after acquiring the first steganographic image, the method further includes: locally saving the first steganographic image. Based on this, the decoder can modify the locally saved steganographic image after saving it locally.

[0009] In one possible implementation, after saving the first steganographic image locally, the method further includes: displaying a first interface, the first interface including a first option to enable / disable the decoding function, the decoding function being the function of decoding the first steganographic information in the first steganographic image; responding to a first operation on the first interface, adjusting the first verification information to second verification information, the first operation being triggering the operation to disable the decoding function in the first option, and the second verification information being verification information that cannot be verified. Based on this, after the decoding end saves the first steganographic image locally, it can display the first option to enable / disable the decoding function on the display interface, allowing the user to choose whether to decode the first steganographic image subsequently. If the user chooses to disable the decoding function, the receiving end can adjust the verification information in the first steganographic image to verification information that cannot be verified, and the receiving end will fail to verify the verification information in the first steganographic image subsequently, allowing the receiving end to stop decoding the first steganographic information in the first steganographic image.

[0010] In one possible implementation, the method further includes: in response to a second operation on the first interface, adjusting the verification information in the first steganographic image to third verification information. The second operation is triggering the operation to enable the decoding function in the first option, and the third verification information is verification information that can be verified. Based on this, if the user selects to enable the decoding function, the receiving end can adjust the verification information in the first steganographic image to verification information that can be verified. This way, the receiving end will be able to verify the verification information in the first steganographic image successfully, and then the receiving end can continue to decode the first steganographic information in the first steganographic image.

[0011] In one possible implementation, the first steganographic image is a single-channel image, and the first verification information occupies a first region in the single-channel image; the area of ​​the first region is smaller than a first preset area; the steganographic information occupies a second region in the single-channel image, and the area of ​​the second region is larger than the first preset area. Based on this, the receiving end can decode only the smaller region in the first steganographic image to obtain the steganographic verification information, and determine whether to decode the larger region to obtain the first steganographic information based on the verification information. Since the area occupied by the first verification information is small, the receiving end only needs less computing resources, power consumption, and time to obtain the verification information, thereby reducing the computing resources, power consumption, and time required for the receiving end to obtain the verification information.

[0012] In one possible implementation, the first steganographic image is a multi-channel image, the first verification information occupies a third region of the first single-channel image, and the first single-channel image is one or more single-channel images obtained by splitting the multi-channel image. The area of ​​the third region is smaller than a first preset area, and the steganographic information occupies a fourth region of the first single-channel image, the area of ​​which is larger than the first preset area. Based on this, in the multi-channel image, the first verification information can occupy only a portion of one or more single-channel images within the multi-channel image, thereby further reducing the computational resources, power consumption, and time required for the receiving end to acquire the verification information.

[0013] Secondly, this application provides an image processing method that can be applied to a sending end. The method includes: steganographically writing first verification information in an image to be sent, and steganographically writing the first steganographic information to be sent in the image to be sent to obtain a first steganographic image. The first verification information is used to trigger the receiving end to decode the first steganographic information in the first steganographic image if the verification is successful; and sending the first steganographic image.

[0014] In one possible implementation, after obtaining the first steganalyte image, the method further includes: locally saving the first decoded image.

[0015] In one possible implementation, after saving the first decoded image locally, the method further includes: displaying a second interface, the second interface including a second option to enable / disable the decoding function, the decoding function being the function of decoding the first steganographic information in the first steganographic image; in response to a third operation on the second interface, adjusting the first verification information to second verification information, the third operation being the operation of triggering the disabling of the decoding function in the second option, the second verification information being verification information that cannot be verified.

[0016] In one possible implementation, the method further includes: in response to a fourth operation on the second interface, adjusting the second verification information to the third verification information, wherein the fourth operation is an operation to trigger the decoding function in the second option, and the fourth verification information is verification information that cannot be verified.

[0017] In one possible implementation, the first steganographic image is a single-channel image, and the first verification information occupies a first region in the single-channel image; the area of ​​the first region is smaller than a first preset area; the steganographic information occupies a second region in the single-channel image, and the area of ​​the second region is larger than the first preset area.

[0018] In one possible implementation, the first steganographic image is a multi-channel image, the first verification information occupies the third region of the first single-channel image, the first single-channel image is one or more single-channel images obtained by splitting the multi-channel image, the area of ​​the third region is smaller than the first preset area, and the steganographic information occupies the fourth region of the first single-channel image, the area of ​​the fourth region is larger than the first preset area.

[0062] To facilitate understanding of the technical solutions of this application, before providing a detailed description of the method for acquiring depth images in the embodiments of this application, the technical terms mentioned in the embodiments of this application will be introduced first.

[0063] Joint Photographic Experts Group (JPEG) compression: A widely used lossy image compression standard that uses the visual characteristics of images to remove redundant information and performs frequency domain coding through discrete cosine transform (DCT) to reduce image file size.

[0064] Web picture format (WEBP) compression: A new image format that uses advanced lossy and lossless compression technologies, providing higher compression efficiency than JPEG, and supporting transparency and animation effects.

[0065] Color space: Defines a mathematical model for color representation that maps colors to a coordinate system, such as red, green, blue (RGB) or hue, saturation, and lightness (HSV), enabling digital images to express different colors.

[0066] Multichannel images: Multichannel images typically include RGB images and red-green-blue alpha (RGBA) images. An RGB image is composed of a three-dimensional array with an M×N×3 format. Alternatively, it can be understood as an RGB image consisting of three M×N two-dimensional images (grayscale images). These three images represent the R (red), G (green), and B (blue) components, respectively, with each component's pixel value ranging from [0, 255]. An RGBA image is composed of a four-dimensional array with an M×N×4 format. An RGBA image adds an A (alpha) channel to the RGB image: the alpha component.

[0067] Image steganography: A technique that hides data within an image, often used for covert communication. It utilizes redundant parts or imperceptible changes in an image to conceal information. Common image steganography algorithms include Least Significant Bit (LSB) steganography, mean-modulated steganography, Discrete Wavelet Transform (DWT) steganography, and Discrete Cosmic Transform (DCT) steganography. LSB steganography embeds secret information by modifying the least significant bit of image pixels. Because the human eye is insensitive to color changes, this method can hide data without significantly altering the image's appearance. Mean Modulation: This technique hides information by embedding data into the mean of image patches, avoiding significant changes to the image content.

[0068] Human eye concealment: refers to the degree to which the information embedded in the data steganography process is not detectable by the human eye, which is usually achieved by controlling the impact of the embedded data on image quality.

[0069] Robustness: refers to the ability of steganography to resist noise, compression and other attacks, ensuring that hidden information can still be correctly decoded after the image has been processed.

[0070] Transform domain: is a representation method in image processing. By performing mathematical transformations on the image (such as Fourier transform, DCT, or DWT), the image is transformed from the spatial domain to the frequency domain or other domains for processing.

[0071] After introducing the technical terms mentioned in the embodiments of this application, the relevant technologies will be introduced below.

[0072] Image steganography refers to a technique that uses redundant parts or imperceptible changes in an image to hide the information to be sent, thereby achieving covert communication. Taking the sending and receiving ends of a webpage link based on image steganography as an example, Figure 1 illustrates a schematic diagram of the transmission of a webpage link based on image steganography between the sending and receiving ends. As shown in Figure 1, when the sending end needs to share a webpage link with the receiving end, it steganizes the webpage link into an image and sends the webpage link to the receiving end (e.g., through a third-party application, APP). After receiving the image, the receiving end decodes the steganographic information in the image to obtain the steganized webpage link. The receiving end displays option 1, which allows the user to jump to the webpage by performing the corresponding operation. Furthermore, the receiving end or the sending end can also save the image containing the steganized webpage link locally and add option 2, enabling / disabling link jumping, to the interface.

[0073] A high-capacity steganography method based on JPEG digital images is also provided in the related technology. As shown in Figure 2, the embedding process of steganographic information includes the following steps: (1) Divide the image into several blocks of size 16*16. If a block does not meet the 16*16 requirement, it is padded with 0 to make it 16*16; (2) Perform DCT transformation on each 16*16 block; (3) Quantize each block using a 16*16 quantization table, that is, divide the value in each 16*16 block by the value on the corresponding 16*16 quantization table; (4) After quantization, embed 2 bits of steganographic information into the last two bits of each value in the upper triangular region of each 16*16 block. The steganographic information can be encrypted; (5) Perform inverse quantization and inverse discrete cosine transform on the image to generate a steganographic image containing steganographic information according to the JPEG encoding rules.

[0074] The process of extracting steganographic information includes the following steps: (1) Decode the steganographic image according to the JPEG encoding rules; (2) Divide the image into several blocks of size 16*16. If a block does not meet the 16*16 requirement, it is padded with 0 to make it 16*16; (3) Perform discrete cosine transform on each 16*16 block; (4) Quantize each block using a 16*16 quantization table, that is, divide the value in each 16*16 block by the value on the corresponding 16*16 quantization table; (5) After quantization, extract 2 bits of steganographic information from the last two bits of each value in the upper triangular region of each 16*16 block; (6) After extracting all the information, combine them into steganographic information according to the embedding order. If the steganographic information is encrypted, it is also decrypted using the encryption rules.

[0075] The aforementioned technologies perform DCT transformation on 16*16 image blocks. Since DCT itself depends on the size and spatial structure of the image, when the image undergoes size changes (enlargement or reduction) during transmission, this technology faces problems such as DCT coefficient distortion, quantization and dequantization failure, and information loss. This results in poor robustness in extracting steganographic information and may lead to decoding failure. The aforementioned technologies do not consider the case of decoding failure and will still force the decoding operation in the event of decoding failure, resulting in a waste of computing resources, power consumption, and time, and affecting overall efficiency.

[0076] Furthermore, in related technologies, the receiving end cannot quickly determine whether steganographic information exists in the received image. After receiving the image, the receiving end typically needs to attempt to decode the steganographic information, but cannot choose whether to decode it, resulting in a waste of computing resources, power consumption, and time, affecting overall efficiency. Alternatively, when the sending end transmits images, some images may require decoding of steganographic information by the receiving end, while others do not. The receiving end cannot determine which parts of the image require decoding and which do not, and can only decode the steganographic information of the entire image, resulting in a waste of computing resources, power consumption, and time, also affecting overall efficiency.

[0077] To address the aforementioned technical problems, this application provides an image processing method. When sending a steganographic image, the sending end adds not only steganographic information but also verification information. After acquiring the steganographic image, the receiving end obtains the steganographic verification information and, if the verification information passes, continues decoding the steganographic information. In this way, the receiving end can verify the verification information in the steganographic image before decoding it, and only decodes steganographic images that pass verification to obtain the steganographic information. This avoids the receiving end decoding images that do not require steganographic decoding, saving computational resources, power consumption, and time.

[0078] The image processing method provided in this application can be applied to electronic devices. For example, the sending end and receiving end mentioned above can be electronic devices. Exemplary examples of electronic devices in this application can be tablet computers, mobile phones, desktop computers, laptops, handheld computers, notebook computers, ultra-mobile personal computers (UMPCs), netbooks, as well as cellular phones, personal digital assistants (PDAs), augmented reality (AR) / virtual reality (VR) devices, in-vehicle devices, etc. This application does not impose any special limitations on the specific form of the electronic device.

[0079] The image processing method provided in this application can be executed by an image processing device, which can be the electronic device shown in FIG3. Furthermore, the execution device can also be the central processing unit (CPU) of the electronic device, or the control module for image processing within the electronic device. This application uses an electronic device executing the image processing method as an example to illustrate the image processing method provided in this application embodiment.

[0096] The mobile phone 200 implements its display function through a GPU, a display screen 294, and an application processor.

[0104] Although not shown in Figure 3, the mobile phone 200 may also include a flash, a micro-projection device, a near field communication (NFC) device, etc., which will not be described in detail here.

[0105] It is understood that the structure illustrated in this embodiment does not constitute a specific limitation on the mobile phone 200. In other embodiments, the mobile phone 200 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0106] After describing the hardware structure of the electronic device, this application uses a mobile phone 200 as an example to introduce the system architecture of the electronic device provided in this application. The system architecture of the mobile phone 200 can adopt a layered architecture, event-driven architecture, microkernel architecture, microservice architecture, or cloud architecture. This embodiment of the invention uses a layered architecture... Taking the system as an example, the software structure of mobile phone 200 is illustrated.

[0107] The methods described in the following embodiments can all be implemented in electronic devices having the above-described hardware structure and system architecture. The following embodiments use a mobile phone 200 as an example to illustrate the methods of this application.

[0108] This application provides an image processing method, as shown in FIG4, which may include steps 401-404.

[0109] Step 401: The sending end steganographically writes the first verification information in the image to be sent, and steganographically writes the first steganographic information to be sent in the image to be sent, to obtain the first steganographic image.

[0110] The first verification information is used to trigger the receiver to decode the first steganographic information in the first steganographic image if the verification is successful.

[0111] In some embodiments, the transmitting end may steganographically write first verification information in a first region of the image to be transmitted, and steganographically write first steganalytic information in a second region of the image to be transmitted. Thus, after receiving the first steganalytic image, the receiving end can decode the first region of the first steganalytic image to obtain the first verification information, and / or decode the second region to obtain the first steganalytic information in the second region.

[0112] Optionally, the sending end can steganographically write the first verification information and the first steganographic information in the image to be sent based on an image steganography algorithm. The image steganography algorithm can be LSB steganography, spatial mean steganography, DCT steganography, DWT steganography, etc., and this application does not limit this to any particular algorithm.

[0113] Optionally, the first verification information in the embodiments of this application can be a binary verification code, a digital verification code, an image verification code, a QR code, a text verification code, or other verification information, and this application does not limit it.

[0114] As an example, the first steganographic information in this embodiment can be the link information of a webpage that the sender needs to share with the receiver. The sender steganographically embeds the webpage link information into the first steganographic image so that the receiver can decode the webpage link information from the first steganographic image and then jump to the webpage shared by the sender based on the webpage link.

[0115] Step 402: The sending end sends the first steganalytic image to the receiving end. Correspondingly, the receiving end receives the first steganalytic image sent by the sending end.

[0116] Step 403: The receiving end verifies the first verification information.

[0117] In one implementation, after receiving the first steganographic image, the receiving end first decodes the first steganographic image to obtain the first verification information in the first steganographic image, and then verifies the first verification information.

[0118] Optionally, the receiving end and the sending end pre-agree on preset verification information for verifying the steganographic image, and pre-agree on a first region where the first verification code is located and a second region where the first steganographic information is located. After receiving the first steganographic image, the receiving end decodes the first verification information from the first region and compares the decoded first verification information with the preset verification information. If they match, the verification is deemed successful; otherwise, the verification fails.

[0119] As an example, the preset verification information is the binary verification code "0011001". If the first verification information decoded by the receiving end from the first region of the first steganographic image is also "0011001", then the receiving end determines that the first verification information has been verified. If the first verification information decoded by the receiving end from the first region of the first steganographic image is not "0011001", then the receiving end determines that the first verification information has failed to be verified.

[0120] Step 404: If the first verification information passes the verification, the receiving end decodes the first steganographic image to obtain the first steganographic information.

[0121] As one implementation, if the first verification information passes, the receiving end decodes the second region of the first steganographic image to obtain the first steganographic information hidden in the second region. If the first verification information fails, the receiving end stops decoding the steganographic content of the first steganographic image and exits the decoding process, thereby reducing the computing resources, power consumption, and time required for decoding by the receiving end.

[0122] As an example, Figure 5 illustrates a process of data transmission between a sender and a receiver based on image steganography provided in an embodiment of this application. As shown in Figure 5, after obtaining the webpage link address information to be shared, the sender adds the webpage link address information and first verification information to the image to be sent to obtain a steganographic image, which is then sent to the receiver. Upon receiving the steganographic image, the receiver obtains and verifies the first verification information in the steganographic image. If the verification passes, it continues to decode the first steganographic information in the steganographic image and redirects to the webpage based on the decoded webpage link address information. If the verification fails, the decoding process stops. Optionally, the sender and receiver can also locally save the steganographic image. The locally saved steganographic image may include: button 1, used to trigger redirection to the webpage link address; and button 2, used to trigger enabling or disabling the decoding function. After disabling the decoding function, the verification information can be adjusted to incorrect verification information; if enabling the decoding function, the verification information can be adjusted to correct verification information. It should be noted that Figure 5 only illustrates the example of the button function triggering a jump to a webpage link and / or triggering the opening or closing of the decoding function. In actual implementation, it can also be achieved in other ways, such as through text options, smart assistants, voice assistants, etc. This application does not limit this.

[0123] This application provides an image processing method in which, when sending a steganographic image, the sending end adds not only steganographic information but also verification information to the image. After receiving the steganographic image, the receiving end obtains the steganographic verification information in the image, and if the verification information passes the verification, it continues to decode the steganographic information in the steganographic image. In this way, the receiving end can verify the verification information in the steganographic image before decoding the steganographic information, and only decode the steganographic image that passes the verification to obtain the steganographic information. This avoids the receiving end decoding images that do not require steganographic decoding, saving the receiving end's computing resources, power consumption, and time.

[0124] In one possible implementation, the first steganographic information is the link address information to the first steganographic image. In this case, referring to Figure 4 and as shown in Figure 6, after step 404 above, the method further includes:

[0125] Step 601: The receiving end jumps to the link address corresponding to the link address information of the first steganographic image.

[0126] In one implementation, when the sending end needs to share a webpage with the receiving end, it determines the webpage's link address, hides first verification information in a first region of the image to be sent, and hides the webpage's link address to be shared in a second region of the image to be sent, thus obtaining a first steganalyte image. The sending end then sends the first steganalyte image to the receiving end. After receiving the first steganalyte image, the receiving end first decodes the first region of the first steganalyte image to obtain the first verification information in the first region, and then verifies the first verification information. If the first verification information passes verification, it continues to decode the second region of the first steganalyte image to obtain the webpage's link address in the second region. After this, the receiving end redirects to the webpage's link address and displays the page corresponding to the webpage's link address.

[0127] As one possible implementation, after decoding the image steganography information, the receiving end can display an option on the screen to navigate to a link address. As an example, as shown in Figure 7, the receiving end prompts the user to navigate to the link address via a button; if the user clicks the button, the receiving end navigates to the link address. Based on this, the sending and receiving ends can share link addresses using image steganography technology.

[0128] In one possible implementation, if the first verification information fails, the receiving end can also indicate that decoding is currently unavailable. Referring to Figure 4 and Figure 8, this process can be specifically implemented through the following steps 801:

[0129] Step 801: If the first verification information fails to pass verification, the receiving end displays the first prompt information, which is used to indicate that the first steganographic information in the first steganographic image cannot be decoded.

[0130] In one possible implementation, when the required steganographic information is absent from the image, or when the steganographic information in the image does not require decoding by the receiving end, the sending end can add verification information that the receiving end cannot verify in the first region of the image. After receiving the image, if the receiving end fails to verify the first verification information, it will stop decoding the steganographic content of the first steganographic image and exit the decoding process. At this time, the receiving end can display a first prompt message on the display interface to inform the user that the first steganographic information in the first steganographic image cannot be decoded.

[0131] As an example, the receiving end can display the first prompt information on the display interface. Figure 9 is a schematic diagram of the receiving end displaying the first prompt information on the display interface provided by this application.

[0132] In one possible implementation, after receiving the first steganographic image, the receiving end can also locally store the first steganographic image and display an interface including a first option to enable / disable the decoding function, thereby enabling or disabling the decoding function for the first steganographic image according to user operation, as shown in Figure 10. This process includes:

[0133] Step 1001: The receiving end displays a first interface, which includes a first option to enable or disable the decoding function. The decoding function is the function of decoding the first steganographic information in the first steganographic image.

[0134] In some embodiments, the receiving end stores the first stegana image locally after receiving it. Afterward, the receiving end can add a "Display First Option" to the display interface showing the first stegana image to prompt the user to select whether to enable / disable the decoding function. This allows the user to flexibly choose whether to enable or disable the decoding function of the first stegana image according to their needs.

[0135] It should be noted that the options displayed on the display interface in this application embodiment may be in the form of buttons, text prompts, smart assistant message prompts, etc., and this application does not limit them.

[0136] Step 1002: In response to the first operation on the first interface, the receiving end adjusts the first verification information to the second verification information. The first operation is to trigger the operation of disabling the decoding function in the first option, and the second verification information is the verification information that cannot be verified.

[0137] The first operation can be a touch operation, or an operation through the input / output device of the receiving end, or an operation through voice commands, action commands, etc. on the first interface. This application does not limit the specific operation.

[0138] Step 1003: In response to the second operation on the first interface, the receiving end adjusts the verification information in the first steganographic image to the third verification information. The second operation is to trigger the operation of enabling the decoding function in the first option, and the third verification information is the verification information that can be verified.

[0139] The second operation can be a touch operation, or an operation through the input / output device of the receiving end, or an operation through voice commands, action commands, etc. on the first interface. This application does not limit this.

[0140] As an example, Figures 11 and 12 show a first option in the form of a button. Based on the display interface shown in Figure 11, if the first verification information passes verification, or if the receiving end adjusts the verification information to the third verification information, the first option displays the option to disable the decoding function. If the user clicks the first option, the receiving end determines that the user has disabled the decoding function. At this time, the receiving end adjusts the verification information to the second verification information. When the receiving end detects steganographic information in the image again, it first obtains the second verification information in the first region of the image. The receiving end performs verification based on the second verification information. If the receiving end determines that there is no steganographic information in the image, or that the steganographic information in the image does not need to be decoded, the receiving end exits the decoding process.

[0141] Based on the display interface shown in Figure 12, if the first verification information fails or the receiving end adjusts the verification information to the second verification information, the first option displayed will enable the decoding function. If the user clicks the first option, the receiving end will determine that the user has enabled the decoding function. At this time, the receiving end will adjust the verification information to the third verification information. When the receiving end detects steganographic information in the image again, it first obtains the third verification information in the first region of the image. The receiving end performs verification based on the third verification information. If the receiving end determines that steganographic information exists in the image, or that the steganographic information in the image needs to be decoded, the receiving end will continue to decode the steganographic information in the second region of the image.

[0142] As another example, as shown in Figure 13, the first option can also be a text-based option. For instance, the first option could include two text options: "On" and "Off." The user can select the "On" option to enable the decoding function that decodes steganographic information in the image, or they can select the "Off" option to disable the decoding function. If the user selects the "Off" option, the receiving end determines that the user has disabled the decoding function, and in this case, the receiving end adjusts the verification information to the second verification information. If the user selects the "On" option, the receiving end determines that the user has enabled the decoding function, and in this case, the receiving end adjusts the verification information to the third verification information.

[0143] As another example, as shown in Figure 14, the first option can also be a first option in the form of a smart assistant. The smart assistant prompts the user whether to enable or disable the decoding function, and the user can enable or disable the decoding function by giving instructions to the smart assistant. If the user instructs the smart assistant to disable the decoding function, the receiving end confirms that the user has disabled the decoding function. In this case, the receiving end adjusts the verification information to the second verification information. If the user instructs the smart assistant to enable the decoding function, the receiving end confirms that the user has enabled the decoding function. In this case, the receiving end adjusts the verification information to the third verification information. The user can instruct the smart assistant using text, voice, gestures, or other commands; this application does not limit this.

[0144] In some implementations, after the sending end generates the first steganographic image, it can also display an interface with a second option to enable / disable the decoding function, thereby enabling or disabling the decoding function for the first steganographic image according to user operation, as shown in Figure 15. This process includes:

[0145] Step 1501: The sending end displays a second interface, which includes a second option to enable / disable the decoding function. The decoding function is the function of decoding the first steganographic information in the first steganographic image.

[0146] Step 1502: In response to the third operation on the second interface, the sending end adjusts the first verification information to the second verification information. The third operation is to trigger the operation of disabling the decoding function in the second option. The second verification information is the verification information that cannot be verified.

[0147] Step 1503: In response to the fourth operation on the second interface, the sending end adjusts the second verification information to the third verification information. The fourth operation is to trigger the operation of enabling the decoding function in the second option. The fourth verification information is the verification information that cannot be verified.

[0148] The sending end displays an interface including a second option to enable / disable the decoding function, and then enables or disables the decoding function for the first steganographic image according to the user's operation. This can be referred to the implementation method of the receiving end displaying an interface including a second option to enable / disable the decoding function, and then enabling or disabling the decoding function for the first steganographic image according to the user's operation in Figures 10 to 14 above. This application will not elaborate on this.

[0149] In some embodiments, the first steganographic image may be a single-channel image or a multi-channel image, wherein the first verification information may occupy a different first region in the single-channel image and the multi-channel image, as detailed below:

[0150] In one implementation, the first steganographic image is a single-channel image, and the first verification information occupies a first region in the single-channel image; the area of ​​the first region is smaller than a first preset area; the steganographic information occupies a second region in the single-channel image, and the area of ​​the second region is larger than the first preset area. In other words, in the single-channel image, the first verification information occupies a small portion of the single-channel image, and the first steganographic information occupies the majority of the single-channel image.

[0151] As an example, Figure 16 shows a schematic diagram of a first region and a second region in a single-channel image. As shown in Figure 16, the first region is located on the upper side of the single-channel image, and the second region is located on the lower side of the single-channel image.

[0152] As another implementation, the first verification information occupies the third region of the first single-channel image. The first single-channel image is one or more single-channel images obtained by splitting a multi-channel image. The area of ​​the third region is smaller than the first preset area. The steganographic information occupies the fourth region of the first single-channel image. The area of ​​the fourth region is larger than the first preset area.

[0153] As an example, taking a multi-channel image as an RGB image, Figure 17 shows that the first region occupies the upper side of the first single-channel image in the RGB image, and the second region is located on the lower side of the first single-channel image and in the other two single-channel images.

[0154] The foregoing primarily describes the solutions provided in the embodiments of this application from the perspective of electronic devices.

Whether a function is executed in hardware or by software-driven hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of this application.

[0155] This application embodiment can divide the image processing device into functional modules or functional units according to the above method examples. For example, each function can be divided into its own functional modules or functional units, or two or more functions can be integrated into one processing module. The integrated module can be implemented in hardware or in software functional modules or functional units. The module or unit division in this application embodiment is illustrative and represents only one logical functional division; other division methods may be used in actual implementation.
