[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0028] In the related art, when associating the advertisement subject with the image itself, the advertisement subject information is generally directly inserted into the advertisement image to achieve the association. However, when the advertisement image produced by this method is displayed on a web page or APP interface, the advertisement subject information will be displayed, which affects the perception of Internet users.

[0029] In view of this, a method for associating advertisement subject information with advertisement images provided in an embodiment of the present application can be applied to a server to achieve the association of advertisement subject information with advertisement images. The method provided in the present application obtains an encrypted string by structured encoding and encrypting the advertisement subject information to be associated, and writes the encrypted string into a preset name field in the file header field of the advertisement image file, thereby obtaining a target advertisement file. When the target advertisement file is subsequently displayed on a web page or other interface, it is no different from an ordinary image, does not affect the perception of Internet users, and improves the user experience.

[0030] According to an embodiment of the present invention, an embodiment of a method for associating advertising subject information with advertising images is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0031] In this embodiment, a method for associating advertisement subject information with advertisement pictures is provided, which can be used for the above-mentioned, Figure 1is a flow chart of a method for associating advertisement subject information with advertisement pictures according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0032] Step S101, obtaining information of the subject of the advertisement to be associated, the advertisement image file and a digital certificate issued by a preset platform, wherein the digital certificate includes a private key.

[0033] Exemplarily, the advertising subject information to be associated is the advertising subject information that needs to be associated with the corresponding advertising image. Advertising subject information refers to the transmitter in the advertising information dissemination activity, that is, the information of the proposer, planner, creator and implementer of the advertising activity. There are three main types of advertising subjects: advertisers, advertising operators and advertisers. In the embodiment of the present application, the advertising subject information may include but is not limited to the name of the advertisement, the name of the advertiser, the location of the advertiser, and the type of advertisement. The preset platform may include but is not limited to the Internet Advertising Monitoring Center platform. The digital certificate is an identity authentication certificate generated by the Internet Advertising Monitoring Center platform, which proves that the information signed with this certificate is information published by the person himself or the organization. The digital certificate includes a private key, which is used for subsequent encryption of the information that needs to be published. The advertising image file can be an advertising image that needs to be associated with the advertising subject information.

[0034] Step S102, structurally encoding the subject information of the advertisement to be associated to obtain target format data.

[0035] Exemplarily, in the embodiment of the present application, the purpose of performing structured encoding on the subject information of the associated advertisement is to convert natural language into data that can be understood by a computer, and the target format data is structured text data.

[0036] Step S103, encrypt the target format data using the private key to obtain a binary encrypted string.

[0037] Exemplarily, in an embodiment of the present application, the target format data can be encrypted by an asymmetric encryption algorithm, which is a secure data encryption method that uses a pair of keys: a public key and a private key. The public key can be shared publicly, while the private key must be kept confidential. If the data is encrypted with a public key, only the corresponding private key can be decrypted; vice versa. The advantage of this encryption method is high security, because even if the public key is made public, the data cannot be decrypted without the private key.

[0038] Step S104: adding a preset name field to the file header field of the advertisement image file.

[0039] Exemplarily, the advertising picture file can be a picture file in the JPG, JPEG, or PNG format. A preset name field is added to the file header field of the advertising picture file as a field to fill in the advertising subject information. In the embodiment of the present application, the picture information is a bunch of binary bytes from a binary perspective, which is divided into a picture file header part and a picture dot matrix information part. The file header field has a corresponding position in the binary byte sequence, and two bytes 0x927C can be added to the end of the picture file header information as a preset name field. The embodiment of the present application does not limit the specific content of the preset name field in the file header field, and those skilled in the art can determine it according to needs.

[0040] Step S105, writing the binary encrypted string into the preset name field of the advertisement picture file to obtain the target advertisement file.

[0041] Illustratively, in an embodiment of the present application, proprietary software of the Internet Advertising Monitoring Center is used to write a binary encrypted string into a preset name field of an advertising image file, thereby completing the association between the advertising subject information and the advertising image file. The processed image has advertising subject information that complies with Internet industry specifications and is securely authenticated by the Internet Advertising Monitoring Center to ensure information security and non-leakage.

[0042] The method for associating advertising subject information with advertising images provided in this embodiment obtains an encrypted string by structured encoding and encrypting the advertising subject information to be associated, and writes the encrypted string into a preset name field in the file header field of the advertising image file, thereby obtaining a target advertising file. When the target advertising file is subsequently displayed on a web page or other interface, it is no different from an ordinary image, does not affect the viewing experience of Internet users, and improves the user experience.

[0043] In this embodiment, a method for associating advertisement subject information with advertisement pictures is provided, which can be used in the above-mentioned server. Figure 2 is a flow chart of a method for associating advertisement subject information with advertisement pictures according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0044] Step S201, obtain the subject information of the advertisement to be associated, the advertisement image file and the digital certificate issued by the preset platform, the digital certificate includes the private key. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0045] Step S202: structurally encode the subject information of the advertisement to be associated to obtain target format data.

[0046] Specifically, the above step S202 includes:

[0047] Step S2021, organizing and encoding the advertisement subject information to be associated in the form of key-value pairs to obtain target format data.

[0048] Illustratively, in the embodiment of the present application, the advertisement subject information is organized into structured text data in the form of key-value pairs according to the requirements of the JSON format, thereby obtaining data in a target format.

[0049] Step S203: Encrypt the target format data using the private key to obtain a binary encrypted string. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0050] Step S204: Add a preset name field to the file header field of the advertisement image file. Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.

[0051] Step S205, write the binary encrypted string into the preset name field of the advertisement picture file to obtain the target advertisement file. Figure 1 Step S105 of the illustrated embodiment will not be described in detail here.

[0052] In this embodiment, a method for associating advertisement subject information with advertisement pictures is provided, which can be used in the above-mentioned server. Figure 3 is a flow chart of a method for associating advertisement subject information with advertisement pictures according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0053] Step S301, obtain the subject information of the advertisement to be associated, the advertisement image file and the digital certificate issued by the preset platform, the digital certificate includes the private key. Figure 2 Step S201 of the illustrated embodiment will not be described in detail here.

[0054] Step S302: Structured coding is performed on the subject information of the advertisement to be associated to obtain target format data. Figure 2 Step S202 of the illustrated embodiment will not be described in detail here.

[0055] Step S303: Encrypt the target format data using the private key to obtain a binary encrypted string. Figure 2 Step S203 of the illustrated embodiment will not be described in detail here.

[0056] Step S304: Add a preset name field to the file header field of the advertisement image file. Figure 1 Step S204 of the illustrated embodiment will not be described in detail here.

[0057] Step S305, write the binary encrypted string into the preset name field of the advertisement picture file to obtain the target advertisement file. Figure 2 Step S205 of the illustrated embodiment will not be described in detail here.

[0058] In some optional embodiments, the method further comprises:

[0059] Step S306: Send the target advertisement file to a preset storage location for storage.

[0060] Exemplarily, the preset storage location may be a pre-built database. The embodiment of the present application does not limit the specific content of the preset storage location, and those skilled in the art may determine it according to needs.

[0061] In some optional embodiments, the method further comprises:

[0062] Step S307: upon receiving the advertisement subject information extraction request sent by the requesting end, the target advertisement file is obtained from the preset storage location.

[0063] Exemplarily, in an embodiment of the present application, the requesting end may include but is limited to a client terminal of the advertisement owner. When receiving an advertisement subject information extraction request sent by the requesting end, the corresponding target advertisement file is extracted from a preset storage location according to the extraction request.

[0064] Step S308, sending the target advertisement file to the requesting end, so that the requesting end extracts the binary encrypted string from the preset name field of the target advertisement file, decrypts the binary encrypted string by using the public key, and obtains advertisement subject information.

[0065] Exemplarily, in an embodiment of the present application, after receiving the target advertising file, the requesting end extracts the binary encrypted string from the location of the preset name field, decrypts the binary encrypted string using the public key to obtain target format data, converts the target format data into a format, and obtains corresponding advertising subject information.

[0066] In some optional embodiments, the method further comprises:

[0067] Step S309: when a display request for a target advertisement file is received, the target advertisement file is obtained from a preset storage location.

[0068] Exemplarily, in an embodiment of the present application, the requesting end of the display request may include but is not limited to a web page or APP platform that publishes advertisements. When a display request for a target advertisement file is received, the target advertisement file is obtained from a preset storage location.

[0069] Step S310: sending the target advertisement file to a display terminal for display.

[0070] For example, in the embodiment of the present application, the target advertisement file is a bunch of binary bytes from a binary perspective, which is divided into a picture file header part and a picture dot matrix information part. The target advertisement file is sent to the display terminal for display. Since the binary encrypted string corresponding to the advertisement main information is only written to the file header position and not written to the dot matrix image, the advertisement main information will not be displayed after the terminal displays it.
