Advanced Fraud Prevention: The Limits of Transaction Monitoring

Fraud detection methods have traditionally focused on using personally identifying information to verify someone’s identity at the start of an interaction or identifying suspicious transactions after fraud has occurred by analyzing patterns in metadata such as transaction amounts, frequency, and destination. Identity validation techniques are getting increasingly complex and frustrating for users and yet still manage to fall behind. The transaction-based approach can work well enough after the fact, but fails to catch the warning signs to actually prevent the fraud in the first place. 

As scammers have increasingly used voice calls to perpetrate fraud, leveraging the ability to manipulate agents emotionally, using such techniques as altering their voice with AI, or evading tricky questions with subtle social cues, it’s become increasingly important to recognize warning signs in real-time. At the same time, it’s become increasingly hard for most of these transaction monitoring systems to keep up, as voice-based communications themselves include a vast amount of nuance that is impossible for traditional systems to understand. 

Current Fraud Solutions Are Not Enough

First, let’s look at what anti-fraud tactics banks, insurers, and other platforms use today:

• Retrospective analysis and subsequent blacklisting identifies fraudulent activity only after it has occurred. It helps prevent repeat offenses by blacklisting known fraudulent phone numbers or IP addresses (although digital systems like VPNs make even this benefit less than certain since the cost of getting a clean number has never been easier), but it does nothing to stop ongoing or first-time attacks.
• Pattern-based transaction analysis analyzes financial transactions (amount, location, timing), known fraudster data (IP addresses, phone numbers), and device patterns. However, much like retrospective analysis, this form of fraud detection happens after-the-fact. 
• Biometric authentication (voice and facial recognition) is intended to verify identities using voiceprints or facial scans. While valuable, these methods can still be bypassed by sophisticated deepfake technology, voice manipulation, and recorded audio playback. As detection gets better so too does the technology to evade detection leaving companies that rely on only biometrics stuck in a cat and mouse game.In addition to the risks of outright incorrect analysis, these tools also introduce serious privacy risks and tend to introduce substantial friction into the user experience. 

Closing the Gaps? Conversation-Based Fraud Detection

Given these limitations, real-time conversational analysis is a must-have in the anti-fraud toolbox. Instead of solely looking at metadata or past transactions, conversation-based fraud detection analyzes live interactions as they occur, identifying suspicious behaviors immediately, taking intervention from reactive to proactive.

Introducing VoiceVault

Modulate’s VoiceVault directly addresses the limitations of traditional fraud prevention methods by:

• Analyzing Conversations in Real-Time: VoiceVault immediately detects synthetic voices, manipulated or recorded audio playback, and emotional manipulation techniques that traditional systems miss, taking into account the full depth of the unfolding conversation including tonality, emotion, behavioral characteristics, and of course the specific content.
• Providing Immediate, Actionable Alerts: VoiceVault generates fraud alerts within seconds, enabling agents and institutions to respond instantly to threats.
• Complementing Existing Biometric and Pattern-Based Solutions: VoiceVault builds a risk score over the course of the conversation, which can be used to trigger direct actions like an account freeze, or simply activate other higher-friction prevention tools like a biometric verification.

But VoiceVault doesn’t just detect fraud—it supplies agents with critical, contextual information precisely when they need it to better mitigate fraud. Capabilities include:

• Immediate On-Call Signals: Real-time alerts directly to agents during suspicious interactions, allowing immediate escalation or fraud mitigation actions, such as terminating calls or implementing specialized fraud scripts.
• Enhanced Contextual Understanding: Provides agents with contextual annotations and concise summaries of detected fraud signals, significantly improving their ability to quickly identify and manage fraud cases.

VoiceVault Not Only Protects Individuals; It Protects Businesses

Preventing fraud is essential, because the consequences for individuals and businesses can be devastating, even with the best remediation efforts. Implementing VoiceVault can benefit organizations by:

• Reducing Financial Losses: Real-time detection and immediate intervention significantly lower fraud-related losses. This includes financial losses from the fraud itself—but also from the cost of remediation and potential lawsuits.
  Strengthening Customer Trust: Consumers are reassured knowing businesses proactively protect them against sophisticated fraud attempts, enhancing overall trust and customer satisfaction.
• Improving Compliance and Risk Management: Proactively monitoring conversations reduces regulatory risks and ensures comprehensive protection against fraud threats.
