Terminal PIN Reset via Token Binding and Clearing Code
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems face inefficiencies when customers forget their customer-specific passwords/PINs, requiring costly support or terminal return for reset, as current reset processes are cumbersome and time-consuming.
Innovation Solution
A method and system for terminals to facilitate easy password/PIN reset by using a token with a clearing code, allowing users to replace customer-specific security data with generic data, utilizing a terminal-token binding process for secure and efficient reset.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a generic password/PIN is assigned to all terminals for manufacturing efficiency, then manufacturing cost and time are reduced, but security is compromised when customers forget their customer-specific password/PIN
Solution Approach 1:
The patent applies preliminary action by pre-assigning a generic password/PIN to all terminals during manufacturing, and simultaneously providing customers with a recovery mechanism (token or email link) that enables password reset without manufacturer intervention. This preliminary setup resolves the contradiction by ensuring both manufacturing efficiency (through generic passwords) and security (through recoverable customer-specific passwords).
2Reliability
If customers are required to program their own customer-specific password/PIN, then security is improved and customer memorability is enhanced, but the process becomes more complex and time-consuming
Solution Approach 1:
The patent introduces an intermediary recovery mechanism (token or email-based verification system) that mediates between the terminal and the customer during password reset. This intermediary simplifies the complex password reset process by providing automated verification and recovery steps, reducing the need for direct customer support intervention while maintaining security.
3Reliability
If customers must return terminals to the manufacturer for password reset, then security is maintained through centralized control, but time and cost are significantly increased
Solution Approach 1:
The patent implements self-service by enabling customers to reset their own passwords through automated mechanisms (token-based or email-based verification) without requiring manufacturer intervention. This self-service capability maintains security through automated verification while dramatically reducing the time and cost associated with password resets compared to returning terminals to the manufacturer.
4Reliability
If customer support is engaged for password reset, then security issues are resolved through expert intervention, but cost and time consumption increase significantly
Solution Approach 1:
The patent enables customers to independently resolve password issues through automated recovery mechanisms, eliminating the need for customer support intervention in routine password reset cases. This self-service approach maintains security through automated verification processes while significantly improving productivity by reducing the burden on customer support teams.

AI summary
A secure password/Personal Identification Number (PIN) reset process is disclosed. The process involves replacing a transportation password/PIN of a terminal with a user-specific password/PIN. During the replacement, the user-specific password/PIN is bound with a token. The token can then be used to securely reset the password/PIN of the terminal back to the transportation password/PIN if the user-specific password/PIN is forgotten or compromised.
