Moruto Co., Ltd. (Headquarters: Yokosuka City, Kanagawa Prefecture; CEO: Jun Kojiri) has announced the launch of a privacy-preserving risk matching feature for EC merchants within 'Pitarep,' a customer support (CS) tool that integrates with Shopify.
This feature aims to mitigate risks such as fraudulent orders and malicious claims by allowing merchants to match risk signals based on anonymized data across multiple businesses. Currently provided as a beta version, the specifications and content may change or stop without notice.
### Background
With the expansion of the EC market, challenges such as repeated cancellations, unreasonable claims, payment delays, and cross-store fraudulent use have become prominent. Traditionally, this information was siloed within individual merchants, making cross-sectional measures difficult.
### Feature Overview
This feature allows risk matching using anonymized signals without directly sharing the raw information held by each merchant. Key characteristics include:
- Irreversible hashing of personal information.
- A system design that prevents individual identification at the central level.
- Statistical determination based on multiple matching elements (2-of-5 method).
- Original data remains under the management of each merchant.
This enables enhanced risk detection while respecting privacy.
### Main Functions
- Risk Matching API (Auxiliary judgment at the time of order).
- Registration and cancellation of report information.
- Shopify Order Event Integration (Automatic reflection of cancellations/refunds via Flow).
- Risk Display (Provided as reference information).
- Integration with Shopify Flow allows for automated processing and conditional branching without code.
*Note: This feature is intended to assist merchant decision-making; final judgments are made by the merchants. It is currently offered for free.
### Integration with Shopify
The feature automatically retrieves order events such as fulfillment and cancellation from Shopify. Using Flow, merchants can update risk information based on their specific transaction results.
### Compliance and Privacy
Designed in accordance with the Act on the Protection of Personal Information and related laws:
- Processing personal information into unidentifiable formats (hashing).
- Structure preventing external sharing of raw merchant data.
- Operation based on Terms of Service and Privacy Policy, including clarification of joint use purposes.
### How to Use
1. Install the 'Pitarep' Shopify app.
2. Open 'Fraud Detection Assistance' within the app, agree to the terms, and start using.
3. Set up Shopify Flow as needed.
### Future Developments
Plans include expanding supported EC platforms, refining risk determination algorithms, expanding the merchant network, and visualizing statistical data. The company aims to contribute to a healthy trading environment for the entire EC industry.
