[0002] In e-commerce shopping scenarios, there are a large number of detailed pictures of products in the seller's store. In order to reduce the cost of picture production, some sellers directly steal pictures of similar products. For this purpose, there are even some automated tools on the Internet that can batch copy pictures in the seller's store, and even obtain all pictures in the seller's store, which greatly facilitates infringement.

[0003] In the related art, watermarks can be added to pictures to prevent them from being stolen, but watermarks can only be used for tracing the source and do not affect the use of pictures. In addition, too few watermarks can be easily removed, while too many watermarks reduce the user experience.

[0004] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0008] According to another aspect of an embodiment of the present application, a picture processing method is also provided, including: a client receives a target page sent by a server, wherein the target page contains an encrypted picture, a target object identifier and a target character string, the encrypted picture is obtained by encrypting pixels of the original picture using a target encryption rule, and the target character string is obtained by encrypting the target encryption rule using the target object identifier; the client decrypts the target character string using the target object identifier to obtain the target encryption rule; the client generates a target decryption rule based on the target encryption rule and a cascading style sheet; the client decrypts the encrypted picture using the target decryption rule to obtain the original picture.

[0009] According to another aspect of an embodiment of the present application, a picture processing method is also provided, including: a server receives an original picture sent by a client; the server randomly generates a target encryption rule; the server uses the target encryption rule to encrypt pixels of the original picture to obtain an encrypted picture; the server uses a target object identifier to encrypt the target encryption rule to obtain a target string; the server generates a target page based on the encrypted picture and the target string; the server sends the target page to the client.

[0010] According to another aspect of the embodiments of the present application, a computer-readable storage medium is also provided, the computer-readable storage medium including a stored program, wherein when the program is running, the device where the computer-readable storage medium is located is controlled to execute the image processing method in any one of the above embodiments.

It is easy to notice that the original image can be obtained by decrypting the encrypted image in the target web page through the cascading style sheet natively supported by the browser in the client, rather than restoring the original image in the memory through the script, which is difficult to be captured by the automated script, thereby achieving the technical effect of improving data security, and then solving the technical problem of poor security in the related technology.

[0030] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Figure 1 FIG. 1 shows a hardware structure block diagram of a computer terminal (or mobile device) for implementing the image processing method. Figure 1As shown, the computer terminal 10 (or mobile device 10) may include one or more (102a, 102b, ..., 102n are used to illustrate) processors 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA), a memory 104 for storing data, and a transmission device 106 for communication functions. In addition, it may also include: a display, an input / output interface (I / O interface), a universal serial bus (USB) port (which may be included as one of the ports of the BUS bus), a network interface, a power supply and / or a camera. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above electronic device. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

[0031] It should be noted that the one or more processors 102 and / or other data processing circuits described above may generally be referred to herein as "data processing circuits". The data processing circuits may be embodied in whole or in part as software, hardware, firmware, or any other combination thereof. In addition, the data processing circuit may be a single independent processing module, or may be incorporated in whole or in part into any of the other components in the computer terminal 10 (or mobile device). As described in the embodiments of the present application, the data processing circuit acts as a processor control (e.g., selection of a variable resistor terminal path connected to an interface).

[0032] The memory 104 can be used to store software programs and modules of application software, such as the program instructions / data storage device corresponding to the image processing method in the embodiment of the present application. The processor 102 executes various functional applications and data processing by running the software programs and modules stored in the memory 104, that is, realizing the above-mentioned image processing method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory.

[0033] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the computer terminal 10. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0034] The display may be, for example, a touch screen liquid crystal display (LCD) that enables a user to interact with a user interface of the computer terminal 10 (or mobile device).

[0035] Figure 1 The hardware structure block diagram shown can be used not only as an exemplary block diagram of the above-mentioned computer terminal 10 (or mobile device), but also as an exemplary block diagram of the above-mentioned server. In an optional embodiment, the above-mentioned server can be a locally deployed server or a cloud server, connected to one or more clients via a data network connection or electronic connection. The data network connection can be a local area network connection, a wide area network connection, an Internet connection, or other types of data network connections.

[0036] Under the above operating environment, this application provides Figure 2 The image processing method shown. Figure 2 1 is a flowchart of a method for processing an image according to Embodiment 1 of the present application. Figure 2 As shown, the method may include the following steps:

[0037] Step S202, obtaining a target page, wherein the target page includes an encrypted image, a target object identifier and a target string, the encrypted image is obtained by encrypting pixels of the original image using a target encryption rule, and the target string is obtained by encrypting the target encryption rule using the target object identifier.

[0038] The target page may be a page that the user currently wants to visit. For example, in an e-commerce scenario, the target page may be a product details page or a seller's store page that the user browses; in a social scenario, the target page may be a personal homepage that the user browses, other users' personal homepages, or a hot information page. In order to protect the images in the target page and prevent them from being stolen, the server may encrypt the original images in the target page, so that the target page sent by the server to the client contains only the encrypted images but not the original images.

[0039] The above-mentioned target object identifier can be a unique identifier of the owner of the original image, such as a user ID. The owner here can refer to the user who took the original image, the designer of the original image, and other users who own the original image. It should be noted that each web page can contain the user ID of the owner of the web page. However, if the owner of the web page is different from the owner of the original image, the user ID contained in the target page is different from the target object identifier, and the encrypted image cannot be decrypted normally later, resulting in the user still viewing the encrypted image. In the embodiment of the present application, the example of the owner of the target page being the same as the owner of the original image is used to explain in detail the detailed process of the client decrypting the encrypted image. Therefore, the target page in the embodiment of the present application contains the target object identifier.

[0040] The above-mentioned target encryption rule can be a randomly generated conversion rule for pixel-level processing of the original image. Through the conversion rule, the processed image is different from the original image. Therefore, the above-mentioned conversion rule can be considered as a target encryption rule for encrypting the original image. It should be noted that the conversion rule is reversible, and there is a corresponding CSS rule for the inverse operation. Optionally, the target encryption rule may include: an image conversion type and multiple image conversion parameters. The image conversion type may include at least one of the following: horizontal mirroring, vertical mirroring, hue rotation, channel swap and channel inversion. The image conversion parameters here may include: angle parameters in hue rotation processing, order parameters in channel swap processing and channels that have been inverted in channel inversion processing.

[0041] The target character string may be a character string obtained by encrypting the target encryption rule using the target object identifier as a key. For the convenience of transmission, the target character string may be a binary character string.

[0042] It is easy to notice that this solution only converts the pixels in the image instead of encrypting the entire image file, so the encrypted image is still an image, thus retaining the characteristics of the image itself, such as being able to display gradually while downloading (streaming mode), supporting back-end size scaling (commonly used for preview images), and other advantages.

[0043] In an optional embodiment, in order to prevent the original image in the web page from being stolen, when the user generates a web page in the server, the server can use the randomly generated target encryption rule to encrypt the original image uploaded by the user, and use the target user ID of the user to encrypt the target encryption rule to obtain the target string, so that the server can only store the web page containing the encrypted image, the target user ID and the target string as the target page for other users to access. When the user needs to access the target page, the user can send an access request to the server through the client. At this time, the server can directly send the web page containing the encrypted image, the target user ID and the target string to the client, and the client will display it to the user for viewing.

[0044] Step S204, decrypt the target character string using the target object identifier to obtain a target encryption rule.

[0045] The target object identifier may be used as a key to decrypt the target character string to obtain a target encryption rule.

[0046] It should be noted that, in the actual decryption process, the client can read the object identifier from the target page, and use the object identifier to decrypt the target string. If the owner of the target page is different from the owner of the original picture, that is, if the encrypted picture in the target page is stolen, then because the object identifier read from the target page is different from the target object identifier, it is impossible to decrypt and obtain the correct target encryption rule, and then the original picture cannot be obtained. If the owner of the target page is the same as the owner of the original picture, that is, if the encrypted picture in the target page is not stolen, then because the object identifier read from the target page is the same as the target object identifier, it can be decrypted to obtain the correct target encryption rule, and then the original picture can be obtained.

[0047] Step S206: Generate a target decryption rule based on the target encryption rule and the cascading style sheet.

[0048] Among them, in order to facilitate transmission, the target encryption rule can be a randomly generated binary number, and each bit is used to represent a different conversion rule. For example, when the image conversion type includes horizontal mirroring, vertical mirroring, hue rotation, channel swapping and channel inversion, the target encryption rule can be a 5-bit binary number T and three parameters R1, R2 and R3. The first bit indicates whether the original image is horizontally mirrored. If the original image is horizontally mirrored, the value of the first bit is 1, and the corresponding inverse operation corresponds to the CSS transform:scale(-1,1) rule; the second bit indicates whether the original image is vertically mirrored. If the original image is vertically mirrored, the value of the second bit is 1, and the corresponding inverse operation corresponds to the CSS transform:scale(1,-1) rule; the third bit indicates whether the original image is rotated by X degrees of hue. (also called hue rotation), X degrees can be a randomly generated angle parameter R1. If the original image is rotated by X degrees, the value of the third bit is 1, and the value of R1 is X. The corresponding inverse operation corresponds to the filter:hue-rotate(Xdeg) rule in CSS, where Xdeg is the angle parameter. The fourth bit indicates whether the channels of the original image are swapped, and R2 indicates the randomly generated order parameter of the swap. If the channels of the original image are swapped, the value of the fourth bit is 1, and the value of R2 is the order parameter of the swap. The fifth bit indicates whether the channels of the original image are inverted, and R3 indicates the randomly generated inverted channels. If the channels of the original image are inverted, the value of the fifth bit is 1, and the value of R3 is the inverted channels. The corresponding inverse operation corresponds to the filter:invert(1) rule in CSS.

[0049] It should be noted that the target encryption rules and CSS rules must correspond one to one, because if the image is horizontally mirrored during encryption, it should also be horizontally mirrored during decryption, so as to eliminate the changes made to the image during encryption and obtain the original image. Therefore, the target encryption rules in this application are all reversible to facilitate the subsequent corresponding decryption processing.

[0050] In an optional embodiment, the inverse operation parameters may be generated according to the target encryption rule and the CSS rule, thereby obtaining the above-mentioned target decryption rule.

[0051] Step S208, decrypt the encrypted image using the target decryption rule to obtain the original image.

[0052] The target decryption rule is used to perform the inverse operation corresponding to the target encryption rule on the encrypted image to obtain the original image.

[0053] It should be noted that the above-mentioned decryption operation can be performed in the client's browser based on CSS rules, which can achieve loading and display at the same time, and decryption is only performed through the browser when rendering in the page. There is no need to restore the original image in the script and then decrypt it. That is, the original image is not included in the memory, and it is difficult for attackers to obtain the original image. Therefore, the technical effect of improving data security can be achieved.

[0054] In an optional embodiment, before decryption, it is necessary to insert a target decryption rule into the front-end script, and pictures with encryption marks in the URL can be hidden by default, thereby preventing them from being displayed before the decryption rule is generated.

[0055] In the existing common technical solutions, the image file is usually encrypted to generate an encrypted binary file. The original image file is obtained through script encryption and rendered to the corresponding position of the web page. However, since the encrypted image is a binary file rather than an image format, it cannot be played backend, which will cause the thumbnail function to be unusable. When used on the front end, the complete binary file must be downloaded and then decrypted and displayed at one time, which makes it difficult to achieve the effect of downloading and displaying at the same time, and the original streaming mode and loading characteristics of the image are lost. In addition, after decryption in this way, the original image data exists in the memory, so the attacker can directly access the data and obtain the original image file.

[0056] In the e-commerce scenario, seller A updates the store and uploads the original image to the server. The server can randomly generate a binary number T=101, and combined with CSS rules, the first digit of T is "1", indicating that the CSS transform:scale(-1,1) rule is used to perform horizontal mirroring of the image, the second digit of T is "0", indicating that the CSS transform:scale(1,-1) rule is used to perform vertical mirroring of the image, and the third digit of T is "1", indicating that the CSS filter:hue-rotate(Xdeg) rule is used to perform hue rotation of the image. Then, the transformation rule T and the parameters involved in the above CSS rules are encoded to obtain a new binary string B, and the seller A's user ID is used as the key to encrypt the string B to obtain the target string. It should be noted that the target string can be used as the image name or page address of the encrypted image, so that the target page is bound to the seller A's user ID. When seller A visits the target page, the client can decrypt the target string based on its user ID and obtain the decryption rules, so that the browser can decrypt the encrypted image in combination with the CSS rules and display the original image after decryption.

[0057] In the embodiment of the present application, after obtaining the target page, it is necessary to use the target object identifier to decrypt the target string to obtain the target encryption rule; based on the target encryption rule and the cascading style sheet, generate the target decryption rule; use the target decryption rule to decrypt the encrypted image to obtain the original image. It is easy to notice that the original image can be obtained by decrypting the encrypted image in the target web page through the cascading style sheet natively supported by the browser, rather than restoring the original image in the memory through the script. The image data is difficult to be captured by the automated script, thereby achieving the technical effect of improving data security, thereby solving the technical problem of poor security in the related technology.

[0058] In the above embodiment of the present application, a target decryption rule is generated based on the target encryption rule and the cascading style sheet, including: based on the target encryption rule, determining the inverse operation parameters corresponding to the target encryption rule; and converting the inverse operation parameters into the target decryption rule according to the cascading style sheet.

[0059] Among them, the inverse operation parameters can be the parameters involved in the inverse operation based on the CSS rules. For example, when performing encryption processing, the R1 parameter is combined for hue rotation processing. When decrypting, the inverse operation parameters can be obtained by subtracting R1 from 360, and then the CSS rules for the user to perform the inverse operation are generated.

[0060] It should be noted that when some low-level image operations are involved, such as modifying image channels, corresponding SVG filters need to be generated for CSS filters to call.

[0061] In the above-mentioned embodiments of the present application, the target character string is stored in the page address of the target page or the file name of the encrypted image.

[0062] The target string may be used as the page address of the target page, that is, the path parameter when the encrypted image is published, or as the file name of the encrypted image.

[0063] In the above embodiment of the present application, the target image identifier corresponding to the encrypted image is stored in the page address.

[0064] The target image identifier is used to identify the file as an encrypted image, so that in the subsequent front-end decryption process, the encrypted image is defaulted to not be displayed to prevent the image from being displayed during the decryption process.

[0065] In addition, during the decryption process, the front end detects the encryption mark, extracts the target string, and encrypts the target string using the target object identifier read from the target page, restores the corresponding target encryption rule and the parameters involved in the encryption process, and then, based on the target encryption rule and the parameters involved in the encryption process, obtains the corresponding inverse operation parameters and inverse operation rules to decrypt the encrypted image.

[0066] In the above embodiment of the present application, before decrypting the encrypted image using the target decryption rule to obtain the original image, the method also includes: inserting the target decryption rule for the encrypted image in the target page.

[0067] In the above embodiments of the present application, the encrypted image is in a hidden state.

[0068] In an optional embodiment, when decrypting at the front end, a target decryption rule, that is, a CSS rule for decryption, is inserted into the page in advance, so that the image with the target image identifier in the URL is not displayed by default. For example, the following code can be added to the URL to prevent the encrypted image from being displayed:

[0069]

[0070] Among them, encrypt is the target image identifier, the first rule corresponds to the image loaded by the img tag, and the second rule corresponds to the image loaded by the CSS background.

[0071] For example, the target decryption rule could look like this:

[0072]

[0073]

[0074] In the above embodiment of the present application, the method also includes: obtaining the original image; randomly generating a target encryption rule; encrypting the original image using the target encryption rule to obtain an encrypted image; encrypting the target encryption rule using a target object identifier to obtain a target string; and generating a target page based on the encrypted image and the target string.

[0075] Among them, after receiving the original picture uploaded by the user, the backend randomly generates a number, and defines the corresponding conversion rule for each bit in the number, that is, the above-mentioned target encryption rule, and then uses the encryption rule to encrypt the pixels of the original picture to obtain an encrypted picture. Combine the encryption parameters involved in the target encryption rule and the target decryption rule to generate a binary string, and use the target object identifier as the key to encrypt the binary string to obtain the target string, which is used as the file name of the encrypted picture or the path of the encrypted picture to generate the target page.

[0076] In the above embodiment of the present application, the target encryption rule is encrypted using the target object identifier to obtain the target string, including: encoding the target encryption rule to obtain binary data; encrypting the binary data using the target object identifier to obtain encrypted data; encoding the encrypted data to generate the target string.

[0077] The above encoding of the encryption rule may be combined with the encryption parameters involved in the encryption rule. For example, in an optional embodiment, the encryption conversion rule is T, and the encryption parameters involved include R1, R2, and R3, which may be encoded and stored in the 16-bit data arr:

[0078] arr = new Uint16Array(3)

[0079] arr[0]=T

[0080] arr[1]=R1

[0081] arr[2]=R2

[0082] arr[3]=R3

[0083] Then convert the 16-bit binary array into an 8-bit binary array:

[0084] bytes=new Uint8Array(arr.buffer)

[0085] Finally, after obtaining the binary data, the target object identifier is used as the key to encrypt the target encryption rule to obtain the encrypted data, and then the encrypted result is encoded into a string, that is, the above-mentioned target string.
