It should be noted that the cloud server described above may provide basic cloud computing services by using cloud technology. Cloud technology refers to a hosting technology for unifying serial resources such as hardware, software, network and the like in a wide area network or a local area network to realize calculation, storage, processing and sharing of data.

In addition, cloud computing (cloud computing) included in the above-described basic cloud computing service refers to a delivery and use mode of IT infrastructure, and refers to obtaining required resources in an on-demand, easily-extensible manner through a network; the generalized cloud computing refers to a delivery and use mode of a service, and refers to obtaining a required service in an on-demand and easily-extensible manner through a network. Such services may be IT and software, internet related, or other services. Cloud Computing is a product of development and fusion of traditional computers and Network Technologies, such as Grid Computing (Grid Computing), distributed Computing (distributed Computing), Parallel Computing (Parallel Computing), Utility Computing (Utility Computing), Network Storage (Network Storage Technologies), Virtualization (Virtualization), Load balancing (Load Balance), and the like.

It should be noted that the computer system 200 of the electronic device shown in fig. 2 is only an example, and should not bring any limitation to the functions and the scope of use of the embodiments of the present application.

As shown in fig. 2, the computer system 200 includes a Central Processing Unit (CPU) 201 that can perform various appropriate actions and processes in accordance with a program stored in a Read Only Memory (ROM) 202 or a program loaded from a storage section 208 into a Random Access Memory (RAM) 203. In the RAM 203, various programs and data necessary for system operation are also stored. The CPU 201, ROM 202, and RAM 203 are connected to each other via a bus 204.

The computer program, when executed by a Central Processing Unit (CPU) 201, performs various functions defined in the methods and apparatus of the present application.

Generally, in the field of advertisement delivery, an advertisement conversion rate is generated by an advertiser according to advertisement revenue, and then a display fee to be paid to an advertisement platform is determined according to the advertisement conversion rate. Referring to fig. 3 in particular, fig. 3 schematically illustrates a data transmission architecture between an advertiser 301 and an advertisement platform 302 in the prior art. As shown in fig. 3, after the advertiser 301 puts the advertisement on the advertisement platform 302, the advertisement platform 302 may obtain the advertisement exposure amount and the click rate and encrypt and feed back the advertisement exposure amount and the click rate to the advertiser 301, and the advertiser 301 may calculate the advertisement display conversion rate according to the advertisement exposure amount, the click rate, and the purchase rate, and then feed back the advertisement display conversion rate to the advertisement platform 302. However, in this way, there is a risk of data tampering, e.g., advertiser 301 may get spurious data that is lower than the true conversion rate by modifying the purchase amount. In addition, in the above process, the advertisement platform 302 generally encrypts the advertisement exposure and click rate in a symmetric manner, such as Message-Digest Algorithm (MD 5). The symmetric encryption mode is easy to crack, and the security of data transmission is influenced. The applicant has therefore appreciated that the above mentioned data tampering problems and security problems of data transmission can be avoided by introducing blockchain techniques by making improvements to the prior art.

The present example embodiment provides a display result generation method. The display result generating method may be applied to the server 105, and may also be applied to one or more of the

terminal devices

101, 102, and 103, which is not particularly limited in this exemplary embodiment. Referring to fig. 4, the display result generation method may include the following steps S410 to S440:

step S410: and acquiring a type of interactive data set corresponding to the display object.

Step S420: and receiving a two-class interaction data set aiming at the display object and sent by the participant equipment, and acquiring two-class evidence storage data corresponding to the display object from the blockchain network.

Step S430: and verifying the correctness of the two types of interactive data sets according to the two types of evidence storage data.

Step S440: and if the second-class interaction data set is correct, generating a display result corresponding to the display object according to the first-class interaction data set and the second-class interaction data set.

By implementing the method shown in fig. 4, uplink data can be performed by using the characteristics of block chain distributed storage and multi-party consensus, so as to reduce the risk of data tampering. In addition, the equipment of the participant can be prevented from uploading wrong data based on contract logic contained in the block chain, so that the accuracy of the display result is guaranteed, and the confidence coefficient of the display result is improved.

The above steps of the present exemplary embodiment will be described in more detail below.

In step S410, a type of interaction data set corresponding to the display object is obtained.

Specifically, the display object may be a multimedia file such as a text, an image, an audio, a video, and the like, and the embodiment of the present application is not limited.

In addition, the step of obtaining a type of interactive data set corresponding to the display object can be executed by the display side device, when a plurality of display objects exist, the display side device can obtain a type of interactive data set corresponding to different display objects, the type of interactive data set of different display objects corresponds to different identifiers, and the identifiers are used as unique representations of the type of interactive data set; the presenter device may be the server 105 or any of the

terminal devices

101, 102, 103 shown in fig. 1.

For example, the display object may be an advertisement, the first-type interaction data set may include click data, and the second-type interaction data set may include purchase data; the click data and the purchase data respectively comprise advertisement information, an interaction timestamp and user information, and the user information comprises at least one of equipment information and account information interacting with the advertisement. In addition, the second-type interaction data set may also include user data such as activation data, registration data, browsing data, and the like, which is not limited in the embodiment of the present application.

For the above example, it should be further noted that the click data is used to represent information corresponding to a user clicking an advertisement, the purchase data is used to represent information corresponding to a user clicking to enter an advertisement and performing a purchase operation, the advertisement information may include an identifier used to represent a displayed advertisement, where the identifier may be represented by a character string, the interaction timestamp is used to represent a time when the click operation or the purchase operation occurs, the device information may include at least one of information such as a device number, a device model, and a device usage frequency, and the account information may include at least one of information such as a user account number, a historical browsing record, and a historical purchase record. In addition, the user information may also include information such as a real-time location and a real-time weather, and the embodiment of the present application is not limited.

Optionally, the manner of obtaining the type of interaction data set corresponding to the display object may specifically be: and acquiring a type of interactive data set corresponding to the display object according to the preset unit time length (such as 1 week), wherein the type of interactive data set comprises all types of interactive data in the preset unit time length. Therefore, the resource utilization rate can be optimized, and the problem of resource waste caused by real-time data acquisition is avoided.

Further, the method may further include the steps of: updating the preset unit time according to the generation frequency corresponding to the historical interactive data; the historical interaction data may be data in a previous data cycle. The method specifically comprises the following steps: if the generation frequency is lower than the preset frequency (for example, 100 times/day), prolonging the preset unit time; if the generation frequency is higher than the predetermined frequency (e.g., 100 times/day), the predetermined unit time is reduced. Therefore, the preset unit time length can be dynamically updated according to the generation frequency of the interactive data, so that the utilization rate of resources is improved.

In addition, optionally, before step S410, the following steps may also be performed: the method comprises the steps that a showing side device deploys a first preset code on a showing side trusted computing platform, wherein the first preset code is used for limiting a mode of acquiring a type of interactive data set; and the participant deploys a second preset code on the participant trusted computing platform, wherein the second preset code is used for limiting a mode of acquiring the second-class interaction data set. It should be noted that the presenter trusted computing platform and the participant trusted computing platform may be a tee (trusted Execution environment) environment, which may also be referred to as "environment". The TEE environment is a trusted computing environment protected by a hardware chip and is used for improving system security.

Further, the following steps may also be performed: the presenter device may also establish a channel with the participant-trusted computing platform through the presenter-trusted computing platform. Furthermore, the presenter trusted computing platform may transmit the remote information certificate to the participant trusted computing platform via the channel; the remote information certificate corresponding to the presenter trusted computing platform may include a hash value used for representing the first preset code and a presenter public key

. And the participant trusted computing platform may transmit the remote information attestation to the presenter trusted computing platform over the channel; the remote information certificate corresponding to the trusted computing platform of the participant can comprise a hash value used for representing the second preset code and a public key of the participant
