Security and Privacy
Data Security
- Encryption: Support for reading analytical data from encrypted S3 buckets.
- Sanitization: Metadata scrubbing for exported assets.
Geospatial Privacy
High-resolution imagery can reveal sensitive information.
Geometric Obfuscation
Random jittering of coordinates for anonymized public releases.
Resolution Downgrading
Automatic resampling to lower resolution for privacy-sensitive areas.
Model Security
Adversarial Defense
Models can be robustified against adversarial attacks using adversarial training.
\min_\theta \mathbb{E}_{(x,y)} \left[ \max_{\delta \in S} \mathcal{L}(f_\theta(x+\delta), y) \right]
where \(S\) is the allowed perturbation set (e.g., \(\ell_\infty\) ball).
