🔒 SAC 2024 Conference: Exploring Cutting-Edge Cryptography for Privacy & Security

We’re excited to share our recent participation at the 2024 Selected Areas in Cryptography (SAC) conference and its colocated summer school. This enriching experience reinforced the critical importance of cryptographic research in building a safer and more resilient digital future.

Conference Overview

SAC 2024 brought together leading researchers and practitioners in cryptography to explore the latest theoretical advances and practical applications for security and privacy. The conference covered a wide range of topics, from fundamental cryptographic primitives to real-world implementations that address pressing privacy challenges.

Key Research Areas Explored

1. Data Deletion & GDPR Compliance 🗑️

One of the critical topics discussed was how to confirm that data has been deleted upon request in accordance with regulations such as GDPR. This challenge involves:

  • Verifiable Deletion: Cryptographic proofs that data has been completely removed
  • Audit Trails: Transparent processes for data deletion verification
  • Regulatory Compliance: Meeting GDPR and other privacy regulation requirements
  • User Control: Empowering individuals to exercise their “right to be forgotten”

2. Age-Restricted Content & Privacy 🔞

The conference explored how to serve age-restricted content to the right people while ensuring their privacy. This involves:

  • Privacy-Preserving Age Verification: Proving age without revealing actual age
  • Zero-Knowledge Proofs: Demonstrating eligibility without exposing personal information
  • Content Filtering: Secure mechanisms for age-appropriate content delivery
  • User Privacy: Protecting sensitive demographic information

3. Secure Machine Learning on Secret Data 🔒

A fascinating area covered was how to run machine learning tasks (such as classification) on secret data. This includes:

  • Homomorphic Encryption: Computing on encrypted data without decryption
  • Secure Multiparty Computation: Collaborative ML without data sharing
  • Privacy-Preserving Classification: ML inference with data privacy
  • Federated Learning: Distributed ML with local data protection
