DeepShield by FinChat

DeepShield by FinChat is the most comprehensive Shield Agents suite—purpose-built for real-time deep-fake and forgery detection across finance, social media, enterprise security, journalism, legal, and document verification. By combining a cutting-edge, multimodal AI core with domain-specific Shield Agents, DeepShield delivers end-to-end authenticity validation, explainable insights, and scalable integrations, ensuring your organization stays one step ahead of synthetic threats.

1. Architecture & Core Technology

DeepShield’s core relies on AI architectures that FinChat customizes for enterprise needs—plus two patent-pending proprietary algorithms:

XceptionNet (FrameNet): A convolutional neural network originally released under the Apache 2.0 license. FinChat fine-tunes pre-trained ImageNet weights on public deepfake datasets (FaceForensics++, DFDC) and proprietary vertical data.
Transformer-Based Temporal Analyzer (TempoTransformer): Based on standard Transformer blocks (MIT-licensed), this network processes frame embeddings to capture temporal inconsistencies (e.g., blink patterns, head pose shifts). FinChat adjusts attention layers and trains on domain-specific sequences.
Wav2Vec2 & Spectral CNN (WaveGuard & SpectroScan): Leveraging Facebook AI’s Wav2Vec2 (MIT license) for speech encoding and lightweight 1D-CNNs for spectral anomaly detection. Custom tuning is applied using public audio deepfake corpora and client feedback.
DeepSignature™ (Proprietary, Patent Pending): An innovative feature-fusion algorithm that synthesizes temporal, spectral, and metadata signals into a unique authenticity signature per session—boosting detection accuracy and minimizing false positives.
CustomDeep™ Core (Proprietary, Patent Pending): FinChat’s from-scratch multimodal baseline model unifies video, audio, and metadata processing in a single architecture—designed for rapid inference and cross-domain consistency.
