AI DeepSign is an enterprise-grade AIGC security infrastructure designed for high-value scenarios such as finance, media, and e-commerce. Through a governance closed loop of "automatic rights confirmation - risk control - traceability forensics", it assigns tamper-proof trusted identity to each piece of AI-generated content (AIGC), addressing the challenges of authenticity verification and compliance evidence for AIGC content.
Background
In recent years, the volume of AIGC content has grown exponentially worldwide, and the abuse of deepfakes and AI-generated content has raised widespread concerns. Regulations such as the EU AI Act and China's Interim Measures for the Management of Generative Artificial Intelligence Services have been introduced, requiring clear labeling and source traceability of AI-generated content. Meanwhile, content platforms urgently need standardized technical solutions to address challenges such as fake content governance, copyright protection, and compliance evidence, and the C2PA (Coalition for Content Provenance and Authenticity) specification is becoming the de facto industry standard.
AI DeepSign is based on the C2PA industry specification and provides an end-to-end service for AIGC content that covers generation, detection, and signature verification. The system supports operations through natural language conversations, requiring no technical background, and can add traceable digital signatures to each piece of AI-generated content.
Product architecture
AI DeepSign is built on Alibaba Cloud's cloud-native capabilities with a three-layer product architecture:
Access layer: Supports two access methods: conversational commands and local file upload, with a built-in multimodal detection engine and automatic signing module.
Analysis layer: Provides AI forgery feature library and deep semantic analysis capabilities, covering the full workflow of identification, signing, and auditing.
Infrastructure layer: Provides hardware-level root of trust for digital signatures, ensuring that signatures cannot be tampered with.

Access detection and automatic signing
By entering generation commands through the natural language dialog box or uploading local files to the platform, you can trigger the automatic rights confirmation process:
Seamless integration and real-time detection: The system automatically invokes the multimodal engine to perform compliance pre-checks on generated content or uploaded files, identifying AI characteristics and sensitive information without installing plugins or configuring encryption keys.
Millisecond-level automatic signature embedding: After the detection is passed, the C2PA standard digital signature is calculated and embedded within milliseconds. The signature information includes the algorithm (ES256), issuer, and timestamp, and is automatically written into the file metadata. For generated content, the AI-generated label is added simultaneously.
Trusted delivery: After signing is completed, the compliant asset with a "digital ID card" is delivered.
Signature verification and risk assessment
When receiving an image or other file, the system performs multiple risk checks:
Signature verification for authenticity: After a file is uploaded, the system automatically verifies the signature integrity. If the signature is valid, the file is shown as untampered, and the certificate is checked for trust. Files without a signature or with tampered signatures are flagged as anomalies.
Multi-dimensional risk scanning and grading: Simultaneously performs AI generation detection, sensitive information and personal privacy screening, and presents a risk rating.
Intelligent decision recommendations and actions: Based on the comprehensive risk assessment, the system provides handling recommendations and supports compliant re-signing or high-risk interception.
Use cases
AI policy anti-counterfeiting and anti-fraud: Automatically applies digital signatures during the electronic policy underwriting process. Claims require mandatory signature verification to intercept unsigned or tampered documents and trace the generation time and responsible person.
AIGC content labeling and copyright confirmation: Automatically embeds digital signatures at the rendering output to prevent unauthorized use or malicious editing. During public opinion disputes, time-stamped proof of originality can be quickly issued.
Product image copyright protection: AI-designed product main images are automatically signed with digital signatures. When counterfeits are discovered, the platform can compare signature differences with one click and initiate the takedown process.
Benefits
Zero-barrier operation: No plugin installation or key configuration required. The entire process of detection, signing, and verification can be completed through natural language conversation, making it easy for non-technical users to get started.
Broad ecosystem compatibility: Digital signatures generated based on the C2PA open standard can interoperate with mainstream content platforms and third-party verification tools, ensuring that signatures remain verifiable during cross-platform distribution.
Precise forgery detection: Capable of identifying high-fidelity deepfakes and forged content that has been secondarily edited, reducing the false positive rate.
End-to-end compliance audit: Every operation from content generation to signature verification is traceable, and structured audit reports are automatically generated to meet regulatory compliance evidence requirements.
