Digital Content Access Logging via Certification Authority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to accurately quantify and record digital content access, particularly in peer-to-peer downloads, which are considered public communication and not protected under private copy royalty payments, necessitating a method to ensure secure and reliable logging of access, origin, and authenticity.
Innovation Solution
A method using coding techniques and certifications, where digital content is encapsulated in a container with a digital certificate, accessed through a main server, and each action generates a time-stamp correlated with access data, stored in a secure log file, ensuring integrity and authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If digital content is distributed through peer-to-peer systems, then accessibility and distribution speed are improved, but the ability to control and quantify access is worsened
Solution Approach 1:
The patent introduces a certification authority as an intermediary between content providers and users. This mediator issues digital certificates that enable tracking and quantification of access to digital content through peer-to-peer networks, resolving the contradiction by maintaining distribution speed while enabling reliable access control through cryptographic verification of user identities and access rights
Solution Approach 2:
The system implements feedback mechanisms where access events are recorded and reported to certification authorities. Users must present their certificates and access logs, creating a feedback loop that enables continuous monitoring and quantification of content access, thereby maintaining reliability in access control while preserving the efficiency of peer-to-peer distribution
2Ease of operation
If access to digital content is freely permitted, then ease of operation is improved, but measurement precision of access is worsened
Solution Approach 1:
Users are equipped with digital certificates and client applications that automatically perform authentication and logging functions. The system enables self-service access where users independently present their certificates and generate access records without manual intervention, maintaining ease of operation while ensuring precise measurement of access through automated cryptographic verification and logging
3Ease of manufacture
If log files are stored without encryption, then ease of manufacture is improved, but security of data is worsened
Solution Approach 1:
The patent applies different security measures to different parts of the system. Log files containing sensitive access information are encrypted using public-key cryptography, while other non-sensitive system components remain unencrypted. This selective application of encryption maintains system simplicity where possible while ensuring data security where required, resolving the contradiction between ease of manufacture and data security

AI summary
A method is described which allows determination of when and wherefrom one or several digital contents has/have been accessed, wherein said determination is performed in a certified manner, including diverse security measures relative to avoiding manipulation of the digital content and its carrier and relative to irrefutably certifying the data that determine said access.
