AI Technical Summary
Current methods for detecting telecommunication fraud are often inaccurate and may lead to missed or incorrect or determinations, leaving the user vulnerable to fraudulent activity, particularly in cases where fraudsters change their phone numbers through VoIP, and existing systems fail to accurately identify fraudulent calls in real-time.
A computer-implemented method using sliding window segmentation for real-time transcription of calls, determining window and aggregate probabilities of fraud, and sending alerts when the aggregate probability exceeds a threshold, with features like speaker identification and adaptive weightings to enhance accuracy.
The method provides real-time detection of telecommunication fraud, minimizing false negatives and false positives by considering both short-term and long-term contexts, and allowing immediate user action, thus protecting users from scams.
