Transaction Security via Pseudonym Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transaction methods in the financial sector are vulnerable to manipulation, particularly in online banking, due to the accessibility of transaction-limiting data, which can lead to attacks like man-in-the-middle attacks, and there is a need for enhanced security measures to protect transaction data.
Innovation Solution
A method that assigns unique pseudonyms to participants, stores transaction data on a notary server, and uses encryption to secure transaction parameters, ensuring that only authorized parties can manipulate transaction data, while preventing unauthorized changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If transaction data is stored and transmitted in accessible formats for online banking, then ease of operation is improved, but security against manipulation deteriorates
Solution Approach 1:
The patent segments transaction data into two distinct components: pseudonyms (public identifiers) and actual transaction data (sensitive information). Pseudonyms are used in public transactions while actual data remains protected on the notary server, allowing online accessibility without exposing sensitive information to manipulation.
Solution Approach 2:
The patent introduces pseudonyms as an intermediary between participants and the notary server. These pseudonyms allow transaction channels to remain accessible and operational while preventing direct access to actual transaction data, thus blocking manipulation vectors while maintaining ease of operation.
2Productivity
If transaction-limiting data is made accessible for online transactions, then productivity is improved, but reliability deteriorates
Solution Approach 1:
By segmenting data into pseudonyms (for fast public exchange) and protected transaction data (for secure verification), the system achieves both high transaction processing speed and security. The notary server can quickly verify transactions using pseudonyms without exposing sensitive data.
Solution Approach 2:
The patent creates pseudonym copies of participant identities that can be freely transmitted and verified in online transactions. These copies enable rapid transaction processing while the original transaction data remains securely stored on the notary server, maintaining reliability.
3Reliability
If pseudonyms are assigned and stored on a notary server, then security is improved, but device complexity increases
Solution Approach 1:
The notary server performs multiple functions: storing pseudonym-to-identity mappings, verifying transaction authenticity, and preventing manipulation. This multi-functionality justifies the added complexity by consolidating security operations in a single trusted component rather than distributing complexity across all participants.

AI summary
The invention relates to a method for carrying out transactions between a number of participants, wherein each of the participants is assigned a unique pseudonym, and wherein the assignment of a pseudonym to a participant, as well as the transaction data of the participant, are stored on a notary server.
