Digital Pen Password Generation via Track Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing password generation methods leave written passwords visible, making them susceptible to unauthorized access, and previous solutions either fail to completely hide the written information or require special inks.
Innovation Solution
A system that uses a digital pen to write on a medium with a two-dimensional code, dividing the password entry area into regions, scanning the code, and converting the writing tracks into symbols, which are then arranged to generate a password that is difficult to infer from the written result.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a password is written on a form using conventional methods, then the password can be easily entered, but the written password becomes visible and susceptible to unauthorized access
Solution Approach 1:
The password entry area is divided into multiple regions, and the password is written in a specific sequence across these regions. This segmentation allows the password to be entered conveniently while the divided regions make it difficult for unauthorized persons to reconstruct the password from the written form alone.
Solution Approach 2:
The patent introduces a temporal dimension to the password entry process by requiring writing in a specific sequence across divided regions. This transforms a static visual problem into a dynamic temporal problem, where the password cannot be deduced merely by viewing the final written state, thus enhancing security while maintaining ease of operation.
2Object-affected harmful factors
If the password entry area is divided into multiple regions with specific writing sequences, then security is enhanced by making the password hard to deduce, but the operation becomes more complex
Solution Approach 1:
The system pre-divides the password entry area into multiple regions and pre-establishes the writing sequence before the user enters the password. This preliminary preparation simplifies the user's task during actual password entry, as they only need to follow the pre-defined sequence rather than figuring out the complexity themselves, thus reducing perceived operational complexity while maintaining security.
3Productivity
If conventional password writing methods are used, then the process is simple and quick, but the written password can be easily read by third parties
Solution Approach 1:
By dividing the password entry into multiple regions that must be completed in sequence, the system maintains productivity through efficient regional processing while the segmentation itself prevents third parties from easily reading the complete password from a single glance at the form.

AI summary
A password generating system includes a scanner, a coordinate obtaining unit, a writing information obtaining unit, a track obtaining unit, a dividing unit, a converter, and an output unit. The scanner includes a stylus part performing writing on a print medium with a code indicating coordinates in a password setting region. The scanner scans the code. The coordinate obtaining unit obtains the coordinates from the code. The writing information obtaining unit obtains writing information specifying the order of writing. The track obtaining unit obtains the track of writing based on the obtained coordinates and writing information. The dividing unit divides obtained tracks into units convertible to symbols. The converter converts the track in each unit into a symbol. The output unit obtains a symbol string by arranging obtained symbols in an order based on the order of writing, and outputs the symbol string as a password.
