2. Secure Data Processing Architecture

PDNob Document Assistant Overview

The PDNob Document Assistant relies on Azure OpenAI LLM and Retrieval-Augmented Generation (RAG) technology to provide precise responses to your requests, with prompt optimization enhancing result accuracy.

To ensure your information security and privacy:

  • Your data is not shared: Only you can access and view related Q&A content.
  • Your data is not used for generative AI training: OpenAI and DeepSeek commit to not using interface data for model training by default.
  • Secure processing: Data is encrypted during transmission and storage, with strict access control enforced.

PDNob AI document processing strictly follows the principle of “minimal data exposure + temporary processing + full encryption”, with the following steps:

2.1 File Parsing and Vectorization
  • PDF files are first uploaded to secure open-source storage for chunking, parsing, and vectorization.
  • Document content is broken into task-related segments to minimize exposure of sensitive information.
2.2 Task-Specific AI Analysis
  • Only the necessary segments are sent to the user-selected AI model (ChatGPT 4o-mini or DeepSeek V3.2).
  • The complete file is never stored or shared in external models.
2.3 Encryption and Access Control
  • Data at rest and in transit is encrypted using AES-256 and TLS 1.2/1.3.
  • The system enforces strict access control; only authorized operations can read data.
2.4 Compliance Monitoring and Auditing
  • The PDNob AI platform complies with global privacy regulations such as GDPR and CCPA.
  • System activity and data flows are fully traceable and auditable, ensuring accountability.

3. Responsible AI Principles

PDNob AI design and usage adhere to internationally recognized responsible AI standards:

  • Security and Abuse Prevention: Prevent sensitive data leaks, misuse, or fraud.
  • Comprehensive Testing: Each feature iteration undergoes rigorous security and accuracy testing.
  • Clear Functional Scope: AI tools only process PDF content and do not access unrelated system data.
  • Continuous Feedback Mechanism: Users can report issues to help optimize workflows.

PDNob embeds AI security and compliance into the Software Development Lifecycle (SSDLC), ensuring protection from design to deployment.
