Empower Your Fraud Defenses: Build Your Own Blocklist with Modular Identity

Proactive Fraud PreventionImplementing a 'Bring Your Own Blocklist' (BYOB) strategy allows businesses to actively combat fraud by identifying and rejecting known bad actors, preventing them from accessing services or creating new accounts, which is crucial for maintaining platform integrity and user trust.

Enhanced Security and ComplianceA custom blocklist strengthens security posture by preventing repeat offenses and helps meet compliance requirements by enforcing bans and exclusions, particularly important in regulated industries like finance and gambling where strict KYC and AML policies apply.

Flexibility and ControlModular identity platforms offer the flexibility to integrate various blocklist criteria, including documents, faces, phone numbers, and email addresses, giving businesses granular control over their fraud prevention strategies and the ability to adapt to new threats quickly.

Didit's Seamless IntegrationDidit's AI-native, modular identity platform provides robust tools to easily implement and manage a BYOB feature through its API and Business Console, offering capabilities like Face Blocklisting and Document Blocklisting, all while leveraging a Free Core KYC and a pay-per-successful-check model.

The Rising Need for Custom Blocklists in Identity Verification

In today's digital landscape, identity verification is more than just confirming who someone is; it's about protecting your platform from sophisticated fraud. While standard identity checks are essential, a 'Bring Your Own Blocklist' (BYOB) feature elevates your defenses, offering a proactive layer of security. Imagine being able to instantly flag and reject users based on past fraudulent behavior, compromised documents, or suspicious biometric data. This is precisely what a custom blocklist enables, moving beyond reactive measures to prevent fraud before it impacts your business.

Traditional identity verification solutions often provide a one-size-fits-all approach, which may not be sufficient for the unique challenges faced by every business. Fraudsters are constantly evolving their tactics, making it imperative for companies to have dynamic and customizable tools at their disposal. A BYOB strategy empowers businesses to leverage their own intelligence about malicious actors, creating a tailored defense system that adapts to their specific threat landscape.

Understanding the 'Bring Your Own Blocklist' Concept

A 'Bring Your Own Blocklist' (BYOB) feature allows businesses to maintain and utilize their own lists of entities (such as individuals, documents, phone numbers, or email addresses) that should be prevented from passing identity verification. This is distinct from a general fraud database, as it's specific to your business's history and risk profile. For instance, if a user attempts to create multiple accounts using different identities but the same phone number, blocklisting that phone number can prevent further abuse.

Key Blocklist Entity Types:

• Document Blocklisting: Prevents the reuse of specific documents identified as fraudulent, stolen, or associated with previous policy violations. Didit's ID Verification captures unique identifiers to fingerprint documents effectively.
• Face Blocklisting: Stops users whose biometric data matches previously blocklisted faces from passing verification. This is invaluable for preventing repeat fraudsters from creating new accounts. Didit's 1:1 Face Match and Face Search capabilities power this.
• Phone Number Blocklisting: Blocks verification attempts from phone numbers associated with abuse or policy violations. Didit's Phone Verification can feed into this.
• Email Blocklisting: Prevents new verifications using email addresses tied to past fraudulent activities or spam. Didit's Email Verification helps identify these.

When any of these blocklisted entities are detected during a new verification session, the system automatically declines it, providing a clear warning. This automated process significantly reduces manual review time and increases the efficiency of fraud prevention efforts.

Benefits of Integrating a Custom Blocklist with Modular Identity

The power of a BYOB feature is amplified when integrated with a modular identity platform. Modular identity solutions, like Didit, allow businesses to pick and choose the verification components they need, creating bespoke workflows. This flexibility extends to blocklisting, enabling a highly customized and effective fraud prevention strategy.

Key Benefits:

• Targeted Fraud Prevention: Focus your defenses on the specific threats your business faces, rather than relying on generic fraud rules.
• Reduced False Positives: By using your own data, you can fine-tune your blocklist to minimize legitimate users being incorrectly flagged.
• Enhanced Compliance: Meet specific regulatory requirements (e.g., AML, age verification) by ensuring known prohibited individuals or entities are blocked. For example, in gambling or alcohol sales, Age Estimation combined with a blocklist can prevent underage individuals from circumventing age gates.
• Operational Efficiency: Automate the rejection of known bad actors, freeing up your team to focus on more complex cases.
• Scalability: As your business grows, your blocklist can scale with it, continuously protecting against new and evolving threats.

Integrating a BYOB feature into your identity verification workflow is a strategic move that pays dividends in fraud reduction and operational savings.

Building Your Blocklist with a Developer-First Approach

For developers and businesses seeking fine-grained control, building a custom blocklist is most effectively done through a developer-first identity platform. Didit provides clean APIs and an instant sandbox, allowing for rapid integration and testing of blocklisting functionalities. The ability to programmatically add items to the blocklist via an API (e.g., Didit's /v3/blocklist/add/ endpoint) means that your fraud detection systems can automatically update the blocklist as new threats are identified.

This API-driven approach allows for dynamic and real-time updates to your blocklist, ensuring your defenses are always current. For example, if your internal fraud detection system identifies a new pattern of abuse linked to a specific phone number, it can instantly add that phone number to Didit's blocklist, preventing any future verification attempts from that number.

Beyond API integration, Didit's no-code Business Console offers a user-friendly interface for managing blocklisted users manually. This hybrid approach caters to both technical and non-technical users, ensuring that your fraud prevention strategy is robust and accessible.
