The Fifth Elephant 2025 Annual Conference

About the talk:
“Life of PII in a Sea of Tokens” isn’t just a talk—it’s a real-world engineering tale.

Our hero? PII (Personally Identifiable Information).
The villain? A tangled web of global compliance laws, in-memory data traps, and cross-border chaos.

This session walks through the journey of building a geo-distributed PII Vault for a global enterprise navigating GDPR, HIPAA, India’s DPDP, and more. From horror stories of billion-dollar breaches to designing a zero-trust architecture using tokenization as an interceptor, this talk is packed with:
• Hard choices between encryption vs tokenization
• Real architectural patterns to minimize compliance scope
• Strategies to offload PII handling from developer teams
• Trade-offs around latency, complexity, and cost
• A twist: how LLMs and GenAI complicate it all

If you’re an engineer or architect building systems at scale, and you care about data security before it hits the headlines, this talk is your blueprint—and your cautionary tale.

Takeaways from the session:

• Learn a practical decision-making framework to protect PII Data
• Real-world patterns to keep PII safe without slowing down your teams
• Architecting a Zero trust solution for PII data protection and Data privacy laws compliance

Who this is for?

This session is ideal for every software engineers, architects, platform engineers, MLOps professionals, and product teams building data pipelines and working with cloud platforms —especially those working with sensitive data
