Digital Security Token Verification Feature Server Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital security tokens are vulnerable to unauthorized copying and misuse, especially when used in data network terminals, as they lack effective protection against unauthorized access and copying, leading to potential identity theft and compromised security.
Innovation Solution
Implementing a method where a digital security token in a data network terminal includes a verification feature protected by a user code, with periodic checks by a server to ensure authorized use, exchanging the verification feature if unauthorized copying is detected, thereby limiting the use of unauthorized copies and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital security tokens are stored locally on user devices, then accessibility and convenience are improved, but vulnerability to unauthorized copying and identity theft increases
Solution Approach 1:
The security system is segmented into multiple components: the security token itself, verification features, user codes, and server-based validation. This segmentation allows the token to be easily accessible while distributing security functions across multiple elements that must work together, preventing unauthorized copying from being sufficient for compromise.
Solution Approach 2:
A server acts as an intermediary between the user device and the authentication system. The server validates verification features and manages token registration, creating an additional layer of security that prevents direct unauthorized access even if the local token is compromised.
2Reliability
If verification features are protected by user codes, then unauthorized access is reduced, but operational complexity increases
Solution Approach 1:
The system employs self-service mechanisms where the security token automatically performs verification of its own integrity and the server automatically detects unauthorized copies. This automation reduces the operational burden on users while maintaining strong security through built-in verification features and periodic server checks.
3Reliability
If periodic verification checks are implemented by the server, then detection of unauthorized copies is improved, but system overhead and processing time increase
Solution Approach 1:
The server performs periodic verification checks at predetermined intervals rather than continuously. This periodic action maintains security by regularly detecting unauthorized copies while minimizing system overhead and processing time by avoiding constant validation.

AI summary
The invention relates to a method for operating a digital security token in a data network terminal device, wherein the digital security token serves to authenticate a user using the data network terminal device and the method comprises the following steps: - Providing the digital security token in the data network terminal device, wherein the digital security token has a verification feature which is stored in the data network terminal device protected against unauthorized access by means of a user code and wherein information about the verification feature and its association with the data network terminal device is stored on a server integrated into the data network;- Verification of the verification feature by the server based on the information about the verification feature and its association with the user within the context of using the digital security token for user authentication and/or within the context of a periodic routine check, wherein the server only transmits a new verification feature necessary for the further operation of the security token to the data network terminal if the verified verification feature is correct. The invention further relates to a corresponding data network terminal with a digital security token.
