The user identification in this embodiment includes, but is not limited to, a digital wallet, etc., which may be a pre-software that provides security for transaction processing and an aggregation of information, including personal information of the user.
It should be noted that, in the present embodiment, the user data referred to or used is allowed by the user when the user usage and the usage range are explicitly notified, and is strictly used within the usage range of the notified user, so that the user privacy and the information security are ensured.
In an actual application scenario, a user generates a user identity by registering an advertisement service, and after the user registers the advertisement service, the user indicates that the user allows an advertiser to place an advertisement when the user accesses a medium, and performs advertisement exposure. After the user registers the advertisement service, a user identity of the user is generated, wherein the user identity comprises a private key of the user and is used for keeping the user identity to be unique.
The user terminal in this embodiment includes, but is not limited to, a mobile terminal, a PC, a microcomputer, a server, and the like, and the user terminal has functions of information processing, data transmission, and the like. The user terminal, the demander platform and the advertisement display media are connected with each other through the internet, a local area network and the like.
In this embodiment, the user terminal directly sends the advertisement request and the access information of the advertisement display medium to the supplier platform. The advertisement request carries the identity of the target user, and the access information comprises a media page in the advertisement display media, such as a webpage address URL. Therefore, in the embodiment, the advertisement request of the user terminal is not sent to the provider platform through the media side, and the user data is prevented from being leaked to the media side.
Optionally, in this embodiment, before generating the advertisement placement request according to the advertisement request sent by the user terminal, the method further includes, but is not limited to: receiving advertisement information and an encrypted token of an identity document sent by a user terminal, wherein the advertisement information comprises an advertisement space, and the encrypted token is obtained by encrypting according to a private key of a target user; storing the advertising information to a database of the supplier platform; the encrypted token is sent to the advertiser.
Specifically, before implementation in this embodiment, the target user registers on a preset server, and generates a user identification DID, an identification DID document, and an interest preference document. The user identification comprises an individual private key of the user, the identity information of the user can be identified or identified through the individual private key, and the identification document comprises but is not limited to encryption operation performed on the private key corresponding to the user identification. The interest preference document includes, but is not limited to, personal information of the target user, such as data of user age, gender, occupation, location, education achievement, hobbies, purchasing behavior, and the like. Data such as individual preference of the user can be obtained through the interest preference document. The user registers on a preset advertisement server to provide advertisement service, and an advertiser/data provider positions the user according to the registration information of the user to acquire the user identity and the identity document of the target user.
Then, the target user can use Verifiable expression (Verifiable presentation) to indicate the data of the user interest preference to the verifier (advertiser/data provider) through the interest preference document, so as to realize that the advertiser/data provider carries out corresponding advertisement pushing according to the user interest preference of the target user.
In this embodiment, the target user negotiates with the advertisement display medium in advance, and acquires the usage right of the advertisement slot in the advertisement display medium by purchasing or booking. The advertisement position can be a fixed position on the URL of the website, or the advertisement position corresponding to the target user dynamically appointed by the advertisement display medium when the target user accesses the URL.
And then, when the user terminal corresponding to the target user accesses the preset website corresponding to the advertisement display medium, if the target user has pre-reserved the advertisement space, feeding back the advertisement space to the user terminal corresponding to the target user. And after obtaining the advertisement position feedback of the advertisement display media, the user terminal sends an advertisement request to the supplier platform.
In this embodiment, the advertisement request sent by the user terminal carries advertisement information and an encrypted token corresponding to the identity document. The advertisement information includes, but is not limited to, an advertisement space on a preset webpage of the advertisement display medium, a receivable advertisement type preset by the target user, advertisement content, and the like.
In an actual application scenario, a user may determine whether to permit an advertiser to present an advertisement to itself based on product information provided by the advertiser. If so, the user encrypts the randomly generated license token with a private key to obtain an encrypted token, which is then sent to the advertiser/DMP. The license token may be updated periodically to revoke advertisement push licenses to advertisers/data providers. Optionally, the number of the license tokens may be one or more, and the plurality of license tokens respectively correspond to different types and different levels of advertisement push licenses.

specifically, after the user terminal sends the advertisement request to the supplier platform, the supplier platform sends the advertisement space corresponding to the target user and the user identity to the advertisement trading platform, and generates the advertisement real-time bidding in the advertisement trading platform. And the advertiser/DMP carries out real-time bidding on the advertisement trading platform through the demand party platform, and if the bidding is successful and the bidding of the target user on the advertisement position is met, the demand party platform requests the encryption token corresponding to the target user from the advertiser/DMP. The advertiser/DMP sends the encrypted token to the supplier platform through the ad exchange platform to enable verification of the target user's license token.
In an actual application scenario, a target user may determine whether to permit an advertiser to present an advertisement to itself based on product information provided by the advertiser. And if so, randomly generating a license token by the user terminal corresponding to the target user according to the identity document, and encrypting the randomly generated license token by using a private key to obtain an encrypted token. The encrypted token is then sent to the advertiser/DMP. The license token may be updated periodically to cancel the advertisement push license to the advertiser/data provider.
S206, sending the permission token to the user terminal so that the user terminal verifies the permission token;
specifically, after receiving the encrypted token sent by the demander platform, the supplier platform decrypts the encrypted token by using the public key corresponding to the target user to obtain the license token. The supplier platform then sends the license token to the user terminal of the target user to enable the user terminal to verify the license token.
If the target user does not successfully verify the permission token, it indicates that the advertiser/DMP does not obtain the advertisement push permission of the user, or the advertisement push permission of the advertiser/DMP has expired. The advertiser/DMP cannot push the advertisement to the user terminal corresponding to the target user.
S208, under the condition that the license token is successfully verified, the advertisement demand parameters corresponding to the target user are sent to the advertisement display media so as to push the advertisements to the user terminal.
If the target user successfully verifies the permission token, the verification success information is sent to the supplier platform, and then the supplier platform sends the advertisement demand parameters corresponding to the target user to the advertisement display media, so that the advertisement is displayed at the advertisement position of the advertisement display media, and the advertisement push of the user terminal is realized.
In this embodiment, the advertisement demand parameters include, but are not limited to, the URL showing the advertisement and the advertisement slot. The advertisement display media obtains the advertisement material from the advertisement media server and displays the advertisement material at the advertisement position of the URL. The advertiser pays the user according to the advertisement display times, duration, clicks and purchasing behaviors.
