Blockchain-Secured Display Apparatus for Timed Advertisement Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current advertisement systems in public places, such as restaurants, lack control over display timing and security, with static ads and no assurance of actual display, and there is a need for secure and controlled advertisement delivery.
Innovation Solution
A blockchain-based system integrating a display device within a holding apparatus, utilizing a private blockchain network for secure ad management, ensuring timely and secure display of advertisements through smart contracts and a mesh Wi-Fi network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If advertisements are displayed on static billboards in public places, then the advertisement content is permanently fixed and visible, but the advertisement cannot be updated dynamically and lacks control over display timing
Solution Approach 1:
The patent transforms static billboards into dynamic display devices that can change content and timing. The system allows advertisements to be updated remotely and displayed only during specified time intervals, converting a fixed static system into a flexible dynamic one through network-connected display devices with programmable control
Solution Approach 2:
The display device is integrated into a multi-functional system that serves both as a public information kiosk and an advertisement display medium. The same device can display various types of content including advertisements, public information, and interactive elements, making it universally applicable for multiple purposes
2Reliability
If advertisements are stored in storage media without security measures, then the advertisement content is easily accessible and modifiable, but the system lacks security and tamper-proof capabilities
Solution Approach 1:
The system performs preliminary verification of advertisement authenticity through blockchain validation before display. The advertisement content is cryptographically signed and verified in advance, ensuring that only authorized and unaltered advertisements are displayed, preventing tampering and unauthorized modifications
Solution Approach 2:
A blockchain network acts as an intermediary between the advertisement source and the display device. This decentralized ledger verifies and records advertisement delivery, providing an impartial and tamper-proof mechanism that ensures reliability without requiring complex point-to-point security systems
3Measurement precision
If advertisers pay for advertisement display at specific times, then the advertisement timing is controlled, but there is no verification that the advertisement was actually displayed at the requested time
Solution Approach 1:
The system implements automatic feedback by recording and verifying advertisement display timing through smart contracts. When an advertisement is displayed, the system automatically logs the timestamp and verifies it against the scheduled time, providing precise measurement and confirmation of display compliance without manual intervention
Solution Approach 2:
The verification system operates autonomously through self-executing smart contracts on the blockchain. The system automatically verifies and records advertisement delivery timing, eliminating the need for external verification mechanisms and providing precise, trustless confirmation that advertisements were displayed as agreed

AI summary
The holding apparatus having an embedded display device that is configured to display a plurality of advertisements in a secure manner for a pre-defined time interval. The holding apparatus comprises a bottom/middle section configured to hold one or more objects, and a plurality of holder sides disposed at each lower end of the bottom/middle section. The holding space is utilized for keeping objects, such as napkins, menu card. Further, a puck connected to a virtual mesh Wi-Fi network 114 connects to a private block chain and the display device to securely display advertisements on the display device of the holding apparatus.
