Encrypted Cookie Phishing Prevention via Personal Passphrase Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods to prevent phishing attacks are inadequate, as users often fail to validate website authenticity, and attackers adapt techniques to bypass existing security measures, leading to continued trickery and information theft.
Innovation Solution
A method using a personal passphrase, where an encrypted cookie is created and validated before accessing a web page, ensuring that only legitimate websites can decrypt and present the passphrase to the user, thereby distinguishing real from spoofed sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually check website validity or security icons, then phishing prevention awareness is improved, but user complexity and ease of operation deteriorate
Solution Approach 1:
The system performs automatic phishing detection and validation without requiring user intervention. The server automatically validates the requested URL against known phishing databases, checks SSL certificates, and presents security indicators to the user automatically, eliminating the need for users to manually verify website authenticity.
Solution Approach 2:
The invention introduces an intermediary validation system between the user and the website. This intermediary automatically performs security checks, validates certificates, and provides security information to the user, simplifying the interaction while maintaining high security standards.
2Reliability
If multiple security validation methods are implemented, then phishing detection capability is improved, but device complexity increases
Solution Approach 1:
The invention combines multiple security validation methods (URL validation, SSL certificate verification, phishing database checking) into a single integrated server-side system. This consolidation maintains comprehensive security checking capability while reducing client-side complexity, as the server handles all validation operations centrally.
3Reliability
If existing phishing prevention techniques are used, then some security coverage is achieved, but adaptability to new phishing methods deteriorates
Solution Approach 1:
The system performs preliminary security validations before users interact with potentially malicious sites. By pre-validating URLs, checking certificates in advance, and comparing against phishing databases before connection is established, the system proactively prevents phishing attacks rather than reacting to them after the fact.

AI summary
The invention provides secure access to a web page using a personal pass-phrase to prevent phishing attacks. Upon requesting a web page from a user device, a determination is made as to whether or not an encrypted cookie exists for the requested web page. An encrypted cookie includes the personal pass-phrase and at least one of an identifier of the user device, an identifier of a web browser from which the web page request is initiated, and information about the network path used to establish the personal pass-phrase. If an encrypted cookie does not exist, the user is provided a capability to create the encrypted cookie including a personal pass-phrase. If the encrypted cookie exists, the user device provides the encrypted cookie with the web page request for use by the web server to validate the web page request using information included in the encrypted cookie. If the web page request is valid, the web server propagates the web page toward the user device, otherwise the user device receives an indication that the web server is invalid.
