Electronic Stylus Wireless Credential Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computing systems lack an efficient method for seamlessly transferring text and authentication credentials between devices using an electronic stylus, limiting user convenience and security.
Innovation Solution
An electronic stylus equipped with a wireless interface and a trusted platform module (TPM) that enables wireless communication and secure storage and transmission of text and credentials between computing systems, allowing for copy-paste operations and secure authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an electronic stylus stores and transmits authentication credentials wirelessly between computing systems, then user convenience and authentication speed are improved, but security risks increase due to potential credential exposure
Solution Approach 1:
The patent introduces a trusted platform module (TPM) as an intermediary security component within the stylus. The TPM securely stores authentication credentials and controls their transmission, acting as a mediator between the credential storage and the wireless communication interface. This ensures that credentials are protected even while enabling convenient wireless authentication between computing systems.
2Reliability
If the stylus includes both wireless communication interface and TPM for secure credential storage, then security is improved, but device complexity increases
Solution Approach 1:
The patent combines the wireless communication interface and the trusted platform module within a single stylus device. By merging these components into one integrated unit, the patent reduces overall system complexity compared to having separate devices for communication and security, while still maintaining both wireless functionality and secure credential storage capabilities.

AI summary
An electronic stylus may include a wireless interface, a memory, and a processor. The wireless interface may be configured to send and receive signals to and from at least a first computing system and a second computing system. The memory may be configured to store text. The processor may be configured to store, in the memory, a text string received from the first computing system via the wireless interface, and send, to the second computing system via the wireless interface, the text string received from the first computing system.
