Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face frustration with smartphone technology due to small screen size and interface limitations, and existing interactive input systems lack efficient methods for user authentication and data sharing across distributed computing devices.
Innovation Solution
A method and system for profile management that involves transmitting identification information from a pointer to a mobile device, matching it with a database, and authenticating the communal device with an authentication server using login information, allowing secure access to user content and generating a workspace based on profile information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users switch from smartphones to larger interactive input devices, then user interaction quality improves, but authentication complexity increases
Solution Approach 1:
The patent introduces a pointer device as an intermediary authentication carrier between the user and the communal display system. The pointer stores user identification information and enables authentication by contacting the display surface, simplifying the authentication process while maintaining security. This mediator approach resolves the contradiction by providing a simple, intuitive authentication mechanism that works well on large displays without increasing system complexity.
Solution Approach 2:
The patent uses a pointer device that contains a copy of user identification information (such as biometric data or unique identifiers) stored in its memory. Instead of requiring complex multi-factor authentication systems, the pointer holds a simplified copy of user credentials that can be easily verified by the display system, reducing authentication complexity while enabling secure access to communal devices.
2Reliability
If multiple devices are used for user authentication, then security improves, but authentication time increases
Solution Approach 1:
The patent performs preliminary authentication actions by pre-storing user identification information in the pointer device's memory before actual use. The pointer is pre-configured with user credentials, allowing for rapid authentication when the user contacts the display surface. This eliminates the need for time-consuming real-time verification processes while maintaining security through the use of stored cryptographic data.
Solution Approach 2:
The pointer device performs self-service authentication by containing its own verification capabilities. The pointer stores user identification information and can independently verify user identity when contacting the display surface, eliminating the need for complex centralized authentication systems and reducing authentication time while maintaining security.
3Adaptability or versatility
If user profiles are stored in the cloud, then data accessibility improves, but data security risks increase
Solution Approach 1:
The patent segments user data storage by keeping sensitive identification information stored locally in the pointer device's memory rather than solely in the cloud. This segmentation approach allows the system to maintain data accessibility through cloud services while reducing security risks by storing critical authentication data in a secure, distributed location that is harder to compromise.
Solution Approach 2:
The pointer device acts as an intermediary between the user and the cloud-based data storage system. It securely stores user identification information locally and uses this local copy for authentication, while still enabling access to cloud-based profiles and content. This mediator approach allows the system to benefit from both cloud accessibility and local security.
Data Source
AI summary
The present invention relates to a method and system for managing profiles for use with touch systems. A user logs into a communal device using a pointer paired with a mobile device. The communal device is authenticated and retrieves the user's profile. The user profile is used to setup a workspace on the communal device. The workspace is granted access to the user's content on a content server. When the communal device has multiple users, each workspace may be shared or not depending on the user's requirements. Each pointer is individually identified to a particular user and workspace.
