Digital Content Header Public Key Embedding for Cryptocurrency Payment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital content distribution methods using cryptocurrencies like Bitcoin lack simplicity and convenience, requiring users to register accounts and expose personal information for payment, and do not effectively protect copyright holders' rights or allow for easy activation and consumption of digital content.
Innovation Solution
A method that embeds information on a public key into the header of digital content, enabling a simplified payment process using cryptocurrencies like Bitcoin, allowing users to play protected digital content without account creation and enabling content providers to receive payments through a new distribution platform.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users register accounts and provide personal information for digital currency payment, then payment security and copyright protection are improved, but user convenience and ease of operation deteriorate
Solution Approach 1:
The patent extracts personal information and account registration requirements from the payment process. By embedding only public key information in the digital content header, the system separates the authentication function from personal data collection, allowing users to pay without exposing sensitive information or creating accounts.
Solution Approach 2:
The patent introduces public key cryptography as an intermediary mechanism. Instead of direct user-authentication-server interaction requiring personal information, the public key serves as a mediator that enables secure payment verification without exposing user identity or requiring account registration.
2Reliability
If digital content is protected with copyright mechanisms, then content provider rights are improved, but content accessibility and ease of use deteriorate
Solution Approach 1:
The patent extracts the authentication mechanism from complex copyright management systems. By embedding only essential public key information in the content header rather than full authentication protocols, the system maintains protection while reducing access barriers.
Solution Approach 2:
The patent enables self-service payment where the digital content itself carries the necessary public key information for verification. Users can autonomously complete payment without requiring content providers to set up individual authentication systems or contracts.
3Reliability
If individual contracts are established between content providers and users, then payment security is improved, but system complexity and transaction time increase
Solution Approach 1:
The patent performs preliminary action by embedding public key information in the digital content header during content creation. This pre-prepared authentication data eliminates the need for real-time contract negotiation or individual authentication setup, allowing immediate payment processing.
Solution Approach 2:
The patent creates a universal payment mechanism where the embedded public key system serves all content providers and users uniformly. This eliminates the need for individual contracts between each content provider and user pair, as the same cryptographic mechanism applies universally across all transactions.

AI summary
A method for a content providing terminal providing at least one technically protected digital content is disclosed. The method includes steps of: (a) the content providing terminal providing the digital content in which information on a public key or pointing information indicating the information on the public key is embedded, wherein the information on the public key or the pointing information indicating the information on the public key is required to make a digital content provider receive digital money; and (b) the content providing terminal supporting a course of removing a state of restriction on the use of the digital content to allow a user terminal which receives the digital content to play the digital content, if the user terminal creates payment information by using the public key and its private key and the created payment information is determined to be true.
