Virtual Machine Interface for Secure Cloud Service Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cloud-based services, users face challenges in preventing source code leakage when using software as a service (SaaS), as service providers can intercept and access user application sources, compromising security.
Innovation Solution
A method involving a license management server that receives a virtual machine interface from a cloud server, installs service provider software, and provides access authority to user terminals through the virtual machine interface, ensuring secure authentication and license management to prevent source code interception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a service providing company installs software directly in user terminals or cloud infrastructure, then service delivery is simplified, but source code security is compromised as the provider can intercept user sources
Solution Approach 1:
The patent introduces a virtual machine interface as an intermediary layer between the service providing company and the user terminal. The service provider installs software in the virtual machine rather than directly in user terminals, which prevents direct access to user source code while maintaining service delivery capability. The virtual machine acts as a mediator that isolates the service provider from user-sensitive data.
2Adaptability or versatility
If users contract with both cloud providing company and service providing company, then service functionality is achieved, but process complexity increases due to multiple contracts
Solution Approach 1:
The patent merges the cloud service infrastructure with the software service delivery by installing the service provider's software within the cloud provider's virtual machine interface. This combination allows users to access services through a single cloud contract while maintaining security isolation, effectively merging two separate service models (IaaS and SaaS) into one integrated solution.
3Ease of operation
If service providing company has authority to operate cloud system, then service management is simplified, but user control over infrastructure is lost
Solution Approach 1:
The patent segments the cloud system authority into two distinct layers: the cloud provider maintains operational authority over the underlying infrastructure, while the service provider gains controlled access to install and manage software within the virtual machine interface. This segmentation allows both parties to have appropriate levels of control without conflict, with the service provider able to manage software deployment while the cloud provider retains infrastructure authority.
Data Source
AI summary
A method for providing a software service of a license management server is disclosed. The method comprises the steps of: receiving a virtual machine interface from a cloud server; installing software of a service provider in the virtual machine interface; transmitting a license to the virtual machine interface; providing ID and password related authority to a user terminal; and providing a service of the software to the user terminal through the virtual machine interface when the user terminal accesses the software. Therefore, source code leakage due to static analysis can be fundamentally prevented.
