Blockchain Smart Contracts for Software License Expiration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing software licensing systems face issues with unauthorized copying and distribution, revenue loss, and reliance on a single entity for validation, which can lead to security risks and lack of transparency.
Innovation Solution
Implementing smart contracts on a blockchain to manage software licenses, ensuring automatic expiration and renewal, reducing dependency on centralized authorities, and maintaining transparency and security through decentralized validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single entity is used for license validation and verification, then the licensing process is simplified and centralized, but security risks increase and transparency is reduced if that entity fails or becomes compromised
Solution Approach 1:
The patent segments the centralized validation function into distributed validation across multiple blockchain nodes. Instead of relying on a single entity, the licensing system is divided into independent validators that collectively perform verification, thereby reducing the impact of any single point of failure while maintaining system functionality.
Solution Approach 2:
The blockchain acts as an intermediary layer between software providers and users, enabling trustless validation through cryptographic proofs and smart contracts. This intermediary mechanism eliminates the need for direct trust in a single validating entity while maintaining simplified interaction through standardized protocols.
2Ease of operation
If traditional centralized licensing is used, then validation is straightforward through a single authority, but transparency and security are compromised when that authority fails
Solution Approach 1:
The blockchain-based system implements continuous feedback through immutable transaction records that transparently log all licensing operations. Each validation, issuance, and renewal event is recorded on the blockchain, providing verifiable feedback that enhances transparency while maintaining operational simplicity through automated smart contract execution.
3Adaptability or versatility
If manual license management is used, then flexibility in handling edge cases is maintained, but overhead and inefficiency increase
Solution Approach 1:
The system implements self-service through automated smart contracts that handle license issuance, validation, and renewal without manual intervention. The smart contracts autonomously execute licensing logic based on predefined conditions, eliminating manual overhead while maintaining flexibility through programmable validation rules and configurable license terms.

AI summary
Systems and methods are directed to managing access to a software instance stored on a virtual machine on a blockchain using a smart contract. The system receives, from a client device of a user, an authorization request to access the software instance. The authorization request can include a token associated with the user. In response to receiving the authorization request, the system accesses the smart contract. Based on the token, a determination is made, through the smart contract, whether the user is an owner of a license to the software instance. In response to determining that the user is the owner, a further determination is made, through the smart contract, whether the license has expired without renewal. Based on the license having expired without renewal, the smart contract autonomously triggers the virtual machine to destroy a container comprising the software instance.
