Authorization Cookie Timing Validation Against Token Fraud
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic payment systems lack effective methods to secure authentication cookies and access tokens, making them vulnerable to fraud, particularly in the face of evolving fraud schemes and increasing fraud rates.
Innovation Solution
A method and system that utilize a server to validate user information, determine network delays, initiate session timers, and manage authentication cookies or access tokens based on time differences and thresholds, including two-factor authentication processes, to enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If authentication cookies and access tokens are used to enable convenient user access, then ease of operation is improved, but security is worsened due to vulnerability to fraud and theft
Solution Approach 1:
The system performs preliminary actions by establishing session timers and time-based validation mechanisms before authentication tokens are stolen or misused. The server records the issuance time of authentication cookies and tokens, and pre-configures session duration parameters, so that when a request is made, the system can immediately validate whether the token is within its valid time window without requiring additional user verification steps.
Solution Approach 2:
The patent replaces traditional mechanical authentication verification (checking only token presence) with a time-based validation mechanism. Instead of merely verifying that an authentication cookie or token exists, the system substitutes this with a temporal check that validates the token's issuance time against the current time and session duration, adding a dynamic time dimension to the authentication process that prevents use of stolen tokens.
2Ease of operation
If traditional authentication systems are used to identify users, then ease of operation is improved, but adaptability to new fraud schemes is worsened
Solution Approach 1:
The system introduces dynamics to the authentication process by implementing time-based session validation. The authentication mechanism is no longer static (token presence alone) but dynamic (token presence plus time validation). The session timer and time difference calculations create a moving target that adapts to each authentication request, making it difficult for fraudsters to reuse stolen credentials outside their valid time window.
Solution Approach 2:
The system implements feedback mechanisms by monitoring authentication patterns and validating time stamps. When a authentication request is received, the system provides feedback by checking whether the token's issuance time is within the valid session duration, and can trigger additional verification steps or alert security systems when anomalies are detected, creating a responsive authentication system that adapts to potential fraud attempts.
3Ease of operation
If session duration is extended to improve user experience, then ease of operation is improved, but security is worsened due to increased exposure time for token theft
Solution Approach 1:
The system changes the parameter of session validation from static token presence to dynamic time-based validation. By introducing time stamps and session duration parameters, the system can control the effective window of token validity. Even if a token is stolen during a long session, the time-based validation ensures it can only be used within the calculated valid period, effectively limiting the exposure risk regardless of the overall session duration.

AI summary
Systems, methods, and computer program products: determine, a network delay equal to a server system time stamp associated with a system time of a server at which a login request from a user device is received by the server minus a first server system time stamp received in the login request; initiate a session timer from a time equal to the first user system time stamp plus the network delay; transmit, to the user device, an authentication cookie or access token; receive, from the user device, a further request including the authentication cookie or access token and a user system time stamp associated with the system time of the user device; validate, the authentication cookie or access token; determine, a time difference between the user system time stamp plus the network delay and the session timer; and authorize or deny, based on the time difference, the further request.
