[0039] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0040] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0041] The following is a brief introduction to the technical terms involved in this application.

[0042] Convolution, the essence of convolution is to use the parameters of the convolution kernel to extract the features of the original data. Through the matrix dot multiplication operation, the value consistent with the convolution kernel feature is extracted. If the convolution layer has multiple convolution kernels, the neural network will automatically learn the parameter values ​​of the convolution kernel so that each convolution kernel represents a feature.

[0043] Pooling. The main purpose of pooling is dimensionality reduction to reduce computational effort and provide some translation invariance during the initial stages of training. Two common pooling operations are average pooling and maximum pooling. Pooling involves sliding a fixed-size window over the input, aggregating each element within the window into a single value as the output.

[0044] Flattening: Flattens the data into a structure suitable for neural networks and is used in the input layer or between the convolutional layer and the fully connected layer. It is usually used between the input layer, convolutional layer, pooling layer, and fully connected layer.

[0045] The image encryption method provided in the embodiment of the present application can be applied to at least the following application scenarios, which are described below.

[0046] With the rapid development of the Internet, multimedia information such as images, videos, and audio has become an important data information on the Internet. Among them, images have become the mainstream information transmitted on the Internet due to their simplicity and visualization.

[0047] At the same time, images contain rich information. When electronic devices transmit images to each other, the text information in these images often involves information such as personal privacy and commercial secrets. Therefore, when transmitting images, the text information in the images needs to be securely encrypted.

[0048] Typically, to encrypt an image, the image is first converted into a one-dimensional array and then encrypted using a traditional encryption algorithm. This results in low encryption efficiency due to the large number of pixels and data volume in an image. Furthermore, if the key is not properly protected, its security is compromised, ultimately leading to the decryption of the encrypted content within the image.

[0049] Figure 1 This is a flowchart of an image encryption method provided in an embodiment of the present application.

[0050] like Figure 1 As shown, the image encryption method may include steps 110 to 150, and the method is applied to a first electronic device, specifically as follows:

[0051] Step 110: When the image to be sent includes text information, obtain a first image from a preset image library.

[0052] Step 120: Determine a first marked image and a first parameter based on the first image.

[0053] Step 130: Encrypt a first region image in the image to be sent according to the first mark image and the first parameter to obtain a first encrypted image, where the first region image includes text information.

[0054] Step 140: Generate a target encrypted image based on the first encrypted image and the first marked image.

[0055] Step 150: Send the target encrypted image to the second electronic device.

[0056] In an embodiment of the present application, when the image to be sent includes text information, a first image is obtained from a preset image library; based on the first image, a first marked image and a first parameter are determined; based on the first marked image and the first parameter, a first area image in the image to be sent is encrypted to obtain a first encrypted image, and the first area image includes text information. Here, compared with encrypting each pixel in the image to be sent, only the first area image where the text information is located is encrypted, which can improve the encryption efficiency, and the first marked image and the first parameter used to encrypt the first area image are difficult to crack, and the text information can be highly securely encrypted to ensure the security of the text information. Finally, based on the first encrypted image and the first marked image, a target encrypted image is generated, and the target encrypted image is sent to the second electronic device, so that the target encrypted image containing text information can be sent to the second electronic device safely and efficiently.

[0057] The contents of steps 110 to 150 are described below:

[0058] This involves step 110 .

[0059] In the case that the image to be sent includes text information, a first image is obtained from a preset image library.

[0060] When preparing to send an image, the first electronic device, acting as a transmitter, first detects whether the image includes text. If the image does not include text, it can be sent directly. If the image does include text, a first image is randomly selected from a preset image library.

[0061] Also, when the image to be sent includes text information, the image to be sent is detected by a text detection algorithm to detect the text box coordinates of the text information in the image to be sent, and the area image corresponding to the text box coordinates is marked as the first area image.

[0062] This involves step 120 .

[0063] Based on the first image, a first marker image and first parameters are determined.

[0064] In a possible embodiment, step 120 may specifically include the following steps:

[0065] Edit the first image according to the editing content input by the user for the first image to obtain a second image;

[0066] Acquire a first marked image corresponding to the edited content from the second image;

[0067] According to a preset correspondence, a first parameter corresponding to the first image is determined. The preset correspondence includes a correspondence between multiple groups of mutually corresponding parameters and images in a preset image library, and the parameters include the first parameter.

[0068] Among them, editing the first image to obtain the second image based on the editing content input by the user for the first image can specifically include: receiving the first input of the user for the first image, the first input includes the editing content; in response to the first input, editing the first image to obtain the second image.

[0069] If the text detection algorithm detects that the second image includes edited content, a first marked image corresponding to the edited content is obtained from the second image. The edited content may be a signature corresponding to the user's first input, and the edited content area is cut out according to the text box coordinates of the edited content and saved as the first marked image.

[0070] Then, a first parameter corresponding to the first image is determined based on a preset correspondence relationship, wherein the preset correspondence relationship includes a plurality of sets of corresponding parameters and correspondence relationships between images in a preset image library, for example, image A corresponds to parameter A, image B corresponds to parameter B, image C corresponds to parameter C, and so on.

[0071] This involves step 130 .

[0072] The first region image in the image to be sent is encrypted according to the first mark image and the first parameter to obtain a first encrypted image, where the first region image includes text information.

[0073] If the image to be sent includes text information, the image to be sent is detected using a text detection algorithm to detect the text box coordinates of the text information in the image to be sent, and the area image corresponding to the text box coordinates is marked as the first area image.

[0074] According to the first marked image and the first parameter, the first area image in the image to be sent is encrypted to obtain a first encrypted image. Compared with encrypting each pixel in the image to be sent, only the first area image where the text information is located is encrypted, which can improve the encryption efficiency.

[0075] In a possible embodiment, step 130 may specifically include the following steps:

[0076] processing the first marked image according to the first parameter to obtain a second marked image;

[0077] The first region image in the image to be sent is encrypted according to the second marked image to obtain a first encrypted image.

[0078] Specifically, according to the first parameter, the pixel values of the pixel points in the first marked image can be processed to obtain a second marked image, and then according to the pixel values of the pixel points in the second marked image, the first area image in the image to be sent is encrypted to obtain a first encrypted image, ensuring the security of the text information in the first area image.

[0079] Among them, the first parameter includes: convolution parameters and pooling parameters. In the above steps of processing the first marked image according to the first parameter to obtain a second marked image, the following steps can be specifically included:

[0080] Perform convolution processing on the first marked image according to the convolution parameters to obtain a third marked image;

[0081] Perform pooling processing on the third marked image according to the pooling parameters to obtain a second marked image.

[0082] Among them, the first parameter can include: convolution parameters and pooling parameters.

[0083] The convolution parameters can include the convolution kernel size and the convolution kernel content. Perform convolution processing on the first marked image according to the convolution kernel size and the convolution kernel content to obtain a third marked image.

[0084] Among them, the pooling parameters can include: the pooling layer size and the pooling method. Perform pooling processing on the third marked image according to the pooling layer size and the pooling method to obtain a second marked image.

[0085] As Figure 2 shown, first, perform convolution processing on the first marked image according to the convolution parameters to obtain a third marked image; among them, the convolution kernel corresponding to "filter" is a 2*2 convolution kernel. Since the pixel points have three channels, the convolution operation respectively performs moving convolution processing on the pixel values of the three channels of the pixel points in the first marked image to obtain a third marked image.

[0086] Then, perform pooling processing on the third marked image according to the pooling parameters to obtain a second marked image. The maximum pooling method can be used to perform pooling processing on the third marked image to obtain a second marked image.

[0087] Understanding the above steps based on the three channels of the pixel points, as Figure 2 shown, the first marked image is "Zhang San", and RGB represents the three-channel pixel values of the pixel points in the first marked image. F1, F2, F3, F4 are the third marked images obtained by performing convolution processing on the first marked image. The rectangle is used to represent the second marked image obtained by performing pooling processing on the third marked image according to the pooling parameters. The final circle is used to represent the first key obtained by flattening the second marked image.

[0088] The step of encrypting the first region image in the image to be sent according to the second marked image to obtain the first encrypted image may specifically include the following steps:

[0089] Flattening the second marked image to obtain a first key;

[0090] The first region image in the image to be sent is encrypted according to the first key to obtain a first encrypted image.

[0091] The second labeled image is flattened to convert the second labeled image into a three-dimensional vector of RGB channels, which is the first key.

[0092] like Figure 2 As shown, the second mark image is flattened to obtain the first key, namely "333".

[0093] Among them, for electronic devices other than the second electronic device, the first mark image and the first parameter are difficult to crack, that is, it is difficult to crack the first key, that is, it is difficult to crack the first area image encrypted based on the first key, and the text information in the first area image can be highly securely encrypted to ensure the security of the text information.

[0094] Encrypting the first region image in the image to be transmitted according to the first key to obtain the first encrypted image may specifically include:

[0095] An XOR operation is performed on the pixel values ​​in the first region image and the first key to encrypt and obtain a first encrypted image.

[0096] Among them, XOR is a mathematical operator. It is used in logical operations. The mathematical symbol of XOR is The computer symbol is "xor". Its operation principle is: if the values ​​of a and b are different, the XOR result is 1. If the values ​​of a and b are the same, the XOR result is 0.

[0097] This involves step 140 .

[0098] A target encrypted image is generated based on the first encrypted image and the first marked image.

[0099] The first mark image is covered on the area of ​​the image to be sent except the first encrypted image to generate a target encrypted image, and then the generated target encrypted image is sent.

[0100] This involves step 150 .

[0101] The target encrypted image is sent to the second electronic device.

[0102] In an embodiment of the present application, when the image to be sent includes text information, a first image is obtained from a preset image library; based on the first image, a first marked image and a first parameter are determined; based on the first marked image and the first parameter, a first area image in the image to be sent is encrypted to obtain a first encrypted image, and the first area image includes text information. Here, compared with encrypting each pixel in the image to be sent, only the first area image where the text information is located is encrypted, which can improve the encryption efficiency, and the first marked image and the first parameter used to encrypt the first area image are difficult to crack, and the text information can be highly securely encrypted to ensure the security of the text information. Finally, based on the first encrypted image and the first marked image, a target encrypted image is generated, and the target encrypted image is sent to the second electronic device, so that the target encrypted image containing text information can be sent to the second electronic device safely and efficiently.

[0103] Figure 1 This is a flowchart of an image encryption method provided in an embodiment of the present application.

[0104] like Figure 1 As shown, the image encryption method may include steps 310 to 350, and the method is applied to the second electronic device, as shown below:

[0105] Step 310: Receive a target encrypted image sent by a first electronic device, where the target encrypted image includes a first encrypted image.

[0106] Step 320: When it is detected that the target encrypted image includes the first marked image, a first image matching the first marked image is searched from a preset image library.

[0107] After receiving the target encrypted image, the second electronic device serving as the receiving end first detects whether the target encrypted image has a first marked image. If the first marked image is detected, the first image in the preset image library that matches the first marked image is found through image detection.

[0108] Step 330: Determine a first parameter corresponding to the first image according to a preset corresponding relationship.

[0109] Step 340: Decrypt the first encrypted image according to the first parameter and the first marked image to obtain a first decrypted image.

[0110] In a possible embodiment, step 340 may specifically include the following steps:

[0111] processing the first marked image according to the first parameter to obtain a second marked image;

[0112] Flattening the second marked image to obtain a first key;

[0113] The first encrypted image is decrypted according to the first key to obtain a first decrypted image.

[0114] Among them, the first parameter includes: a convolution parameter and a pooling parameter. The above-mentioned step of processing the first labeled image according to the first parameter to obtain the second labeled image can specifically include the following steps: performing convolution processing on the first labeled image according to the convolution parameter to obtain a third labeled image; and performing pooling processing on the third labeled image according to the pooling parameter to obtain the second labeled image.

[0115] The first labeled image is convolved and pooled to obtain a second labeled image, which is then flattened into a three-dimensional RGB array to obtain the first key. The irreversible nature of convolution and pooling operations prevents the first key from being cracked, resulting in a unique encryption method with high security.

[0116] Step 350: Generate a target decrypted image based on the first decrypted image and the first marked image.

[0117] After decryption, the first marked image in the target encrypted image is erased using image fusion technology, the original image is restored, and the reception of the target decrypted image is completed.

[0118] In an embodiment of the present application, a target encrypted image sent by a first electronic device is received, the target encrypted image includes a first encrypted image; when it is detected that the target encrypted image includes a first marked image, a first image matching the first marked image is searched from a preset image library; according to a preset correspondence, a first parameter corresponding to the first image is determined; according to the first parameter and the first marked image, the first encrypted image is decrypted to obtain a first decrypted image. Here, the first marked image and the first parameter used to decrypt the first area image can only be obtained by a pre-agreed second electronic device, which can ensure security, and the part of the target encrypted image that needs to be decrypted is only the first encrypted image, so the first encrypted image can be decrypted quickly and efficiently to obtain the first decrypted image. Finally, according to the first decrypted image and the first marked image, a target decrypted image is generated, and the target decrypted image can be obtained safely and efficiently.
