Server-Based Digital Content Lending with Time-Limited Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for lending or gifting copyrighted digital goods face safety hazards and loss of copyright control, as users must install or physically transfer digital content, making it difficult to manage digital rights.
Innovation Solution
A server-based method for sending and lending digital service content, which includes receiving user requests, determining label types, and generating lending labels with borrower identifiers and lending periods to control access and manage digital rights electronically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users purchase digital goods and perform installation and authorization on the device of a friend using the user's account, then the digital goods can be accessed by the friend, but safety hazards occur and copyright control is lost
Solution Approach 1:
The patent introduces a server as an intermediary between the lender and borrower. The server manages authorization tokens and lending relationships, mediating the digital goods lending process. This resolves the contradiction by enabling convenient peer-to-peer lending while maintaining centralized copyright control through the server's authentication mechanisms.
Solution Approach 2:
The patent creates a digital copy of the authorization mechanism through lending labels and tokens. Instead of transferring actual digital goods or account credentials, the system generates copyable authorization tokens that grant temporary access rights. This allows the lender to maintain copyright control while enabling the borrower to access the digital goods.
2Adaptability or versatility
If digital service content is lent to others, then the lending function is achieved, but copyright control is lost
Solution Approach 1:
The patent implements dynamic authorization through time-limited lending periods and revocable tokens. The lending label contains validity periods and conditions that dynamically control access rights. This enables versatile lending functionality while maintaining reliable copyright management through automated expiration and revocation mechanisms.
Solution Approach 2:
The system implements feedback loops where the server continuously monitors token usage and validates lending conditions. When a lending period expires or conditions are violated, the server automatically revokes access rights. This feedback mechanism ensures copyright control is maintained while allowing flexible lending operations.
3Ease of operation
If installation and authorization are performed on friend's device using user account, then digital goods access is enabled, but safety hazards occur
Solution Approach 1:
The patent extracts the authorization mechanism from the user account itself. Instead of sharing account credentials or performing direct installation authorization, the system generates separate lending labels and tokens that contain only the necessary access rights. This extraction eliminates safety hazards related to account security while maintaining convenient access for borrowers.

AI summary
The present invention provides a method and a server for sending and lending digital service content. The method for sending digital service content includes: receiving, by a server, a user request, in which the user request carries a user identifier and a label of the digital service content; determining a type of the label; if the label is a lending label of the digital service content, acquiring a borrower identifier in the lending label; and determining whether the user identifier is the same as the borrower identifier; if the user identifier is the same as the borrower identifier, acquiring a lending period matching the borrower identifier in the lending label, and determining whether the digital service content is in the lending period; if yes, sending the digital service content to a terminal used by a user and identified by the user identifier.
