Identify patterns on Transaction
Problem
Detecting merchant, insider fraud in Crypto Payment system is difficult and identifying new types of risks in a timely manner is even harder
Solution
A Deep learning approach in Managing risk – through transaction pattern discovery to determine emerging risk in Crypto Payment behaviour
Total to date
This is the total amount allocated to Identify patterns on Transaction.
About this idea
What is this about?
Building a Machine learning Model to manage risk on Volibra -Decentralised Payment System.
One of the most critical requirements for operating a healthy and trustworthy decentralised payment system is ensuring the confidence of the merchants in the payment network, as well as their customers.
Investigating abnormal transaction activity requires a more complex analysis and significantly more time. Traditional financial systems and regulators are constantly struggling to identify anomalies and separate true from false positives. Today's DeFI players are not left out from these challenges. What happens when Crypto payment becomes mainstream?
The possibility of automating this process by extracting specific transaction activity could provide DeFI teams on Cardano with the opportunity to react faster to incidents and to identify abnormal patterns in a more precise manner.
The goal of this project is to build a model that can identify this risk in DeFi System.
The Plan: The Model ,Roadmap and Milestones
Approach: capture, analyse, visualise and Alert
Model-(Volibra Similarity Score)
A bit of context for CA/VCA with minimal knowledge with regard to Machine learning. Check Machine learning Clustering model on Google.
Volibra Similarity Score will be a machine learning clustering model that will identify patterns of disruptive or manipulative transaction behaviour.
Volibra Similarity Score will be a clustering algorithm that slices payment activity data into clusters based on time, merchant ID, transaction type and the time proximity of other payment actions etc.
As each cluster represents a time slice of payment transaction activity, the ML algorithm will classify this activity in a specific category that is a representative of the merchant's actions for that time period.
These transaction activity clusters may be thought of as packets of intent since each cluster contains a group of payment actions (payment request, refund ,modifying, or canceling) that may well be related, given the time proximity of these events.
Our clustering approach will offer a better view to investigators since the full context of the potential abnormal transaction behaviour will be captured, analysed and visualised.
Each Cluster model targets a specific category of abnormal or manipulative payment transaction activity.
The concept of the similarity score addresses this problem, by scoring each alert based on the degree of quantitative similarity to past actions. This similarity score is generated for each cluster on a scale of 0 to 100, pointing to the clusters that have the highest risk of drawing future regulatory attention and therefore are the most important for immediate review.
