Description

Marketplace Server and How It Works

[0001] The present disclosure relates to a marketplace server providing advertising services.

[0002] The existing advertising market has various intermediary platforms from advertisers to publishers who post ads, and a significant amount of actual costs are spent at the distribution stage.

[0003] In other words, the current advertising market requires advertisers to use many intermediary platforms to show their ads to users, resulting in intermediary fees of approximately 50% or more.

[0004] Additionally, due to the complexity of the relay platform, fraud exists during advertising distribution, and the effectiveness of advertising cannot be confirmed in real time, so advertising costs are unconditionally spent within the contract period.

[0005] Additionally, user data is used by service providers or advertising platform companies for accurate advertising targeting, but there is virtually no profit from users.

[0006] The Personal Information Protection Act is expected to make it more difficult to use personal information for advertising targeting, and the increased complexity of using intermediary platforms makes it impossible to measure the effectiveness of advertising in real time, resulting in advertising costs being unconditionally spent even on ineffective publishers.

[0007] In this way, advertising media continues to increase due to the increase in various devices and services, but the network that distributes advertisements is very complex, resulting in high costs and pain points for all parties involved, including advertisers and publishers.

[0008] Blockchain technology is being used to solve these problems, but user participation is low.

[0009] The purpose of this disclosure is to directly register advertising areas (where advertisements can be displayed) and data within the user's device's default home screen, such as the launcher app, using blockchain technology to the marketplace.

[0010] Additionally, the present disclosure aims to enable advertisers to directly purchase advertising space from users registered in the marketplace, thereby enabling them to check advertising effectiveness in real time, save on intermediary platform costs, and prevent fraud at the source.

[0011] A marketplace server according to an embodiment of the present disclosure may include a communication interface for receiving advertisement sales information including personal information, advertisement area information, and advertisement usage information from a user device, a database for storing the advertisement sales information, and a controller for receiving an advertisement purchase request for the advertisement sales information from an advertiser service server, and transmitting advertisement purchase confirmation information including a reward to the user device according to the received advertisement purchase request.

[0012] A method of operating a marketplace server according to an embodiment of the present disclosure may include a step of receiving advertisement sales information including personal information, advertisement area information, and advertisement usage information from a user device, a step of storing the advertisement sales information, a step of receiving an advertisement purchase request for the advertisement sales information from an advertiser service server, and a step of transmitting advertisement purchase confirmation information including a reward to the user device according to the received advertisement purchase request.

[0013] According to an embodiment of the present disclosure, accurate target advertising is possible, efficient advertising cost execution is possible through real-time advertising measurement, and there is no cost loss due to fraud.

[0014] Additionally, advertising purchase contracts can be changed from the existing quarterly basis to daily / monthly / hourly basis for efficient advertising operation.

[0015] Additionally, you can check feedback from customers who have viewed your advertisements in real time to respond to follow-up marketing activities.

[0016] From a user perspective, monetization can be achieved by providing direct advertising space and data.

[0017] Operators who run marketplace servers can create new revenue streams by developing new advertising distribution platforms.

[0018] Additionally, for the sale of our own devices, we may operate a program that provides a monthly discount on the device sales cost if users agree to our advertising service.
