Secure Personal Identification Code Delivery via Authenticated Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for supplying personal identification codes to security modules, such as chip cards, are complex and expensive, and can be easily compromised, allowing intercepted cards to be misused.
Innovation Solution
A method and system where a user accesses a server via a network to receive a personal identification code, using an authentication code transmitted as a one-time password, ensuring secure electronic transmission coupled with user authentication, preferably via SMS or internet messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the personal identification code is delivered to the user by mail in a separate letter, then the code can be delivered securely, but the process becomes complicated and expensive
Solution Approach 1:
The patent replaces the mechanical/mail-based delivery system with an electronic communication system. The personal identification code is transmitted electronically to the user's terminal device through authenticated communication channels, eliminating the need for physical mail delivery while maintaining security and reducing complexity
Solution Approach 2:
The patent introduces an intermediary authentication mechanism where the user must provide personal data that is verified against stored information before the identification code is released. This intermediary step ensures secure electronic delivery without requiring complex physical mailing procedures
2Ease of operation
If the identification code is formed from the card number or date of birth, then the user can easily remember the code, but the security is compromised as it can be easily ascertained
Solution Approach 1:
The patent introduces an intermediary authentication step where the user must provide personal data (such as card number or date of birth) that is verified against stored information in the system. The identification code is only released after successful verification, preventing unauthorized access while still allowing legitimate users to retrieve their codes
Solution Approach 2:
The patent replaces the static code generation method (deriving code directly from card number or birth date) with a dynamic authentication system. The system electronically verifies user-provided data against stored records and conditionally releases the identification code, transforming the security mechanism from passive to active verification
3Device complexity
If the personal identification code is transmitted electronically to the user, then the delivery process is simplified and cost-reduced, but security risks increase without proper authentication
Solution Approach 1:
The patent introduces an intermediary authentication mechanism where the user must provide personal data that is verified against stored information before the identification code is transmitted electronically. This ensures that only authorized users can receive the code, maintaining security while enabling simplified electronic delivery
Solution Approach 2:
The patent implements a feedback mechanism where the system verifies user-provided personal data against stored records and provides confirmation or rejection accordingly. This feedback loop ensures secure electronic transmission by confirming user identity before releasing the identification code
Data Source
AI summary
A method for providing a personal identification code of a security module, includes a personal identification code assigned to the security module and a server is provided which a user of the security module can access after an authentication. In the method, triggered by a request from the user at the server, an authentication code is transmitted to a terminal of the user by means of a first message. An authentication code input by the user is received at the server, whereupon it is verified whether the input authentication code matches the authentication code transmitted to the terminal, wherein, in the case of a match, the personal identification code is transmitted to the terminal of the user by means of a second message.
