Informationally Compressive Anonymization: Non-Degrading Sensitive Input Protection for Privacy-Preserving Supervised Machine Learning
This paper introduces Informationally Compressive Anonymization (ICA) and the VEIL architecture, a privacy-preserving ML framework that achieves strong privacy guarantees through architectural and mathematical design rather than noise injection or cryptography. ICA transforms raw inputs into low-dimensional, task-aligned latent representations, ensuring only irreversibly anonymized vectors are exported. It rigorously proves structural non-invertibility, driving reconstruction probability to zero, and preserves predictive utility by aligning representation learning with supervised objectives. The VEIL architecture enforces strict trust boundaries, supports scalable multi-region deployment, and aligns with privacy-by-design regulatory frameworks, establishing a secure, performant, and safe foundation for enterprise ML.

Informationally Compressive Anonymization (ICA)
ICA embeds a supervised, multi-objective encoder within a trusted Source Environment to transform raw inputs into low-dimensional, task-aligned latent representations. This ensures that only irreversibly anonymized vectors are exported to untrusted training and inference environments, rigorously proven structurally non-invertible via topological and information-theoretic arguments. This design makes inversion logically impossible, even under idealized attacker assumptions, with the attacker's conditional entropy over the original data diverging to zero reconstruction probability. Unlike prior autoencoder-based approaches, ICA preserves predictive utility by aligning representation learning with downstream supervised objectives, enabling low-latency, high-performance ML without gradient clipping, noise budgets, or encryption at inference time.
VEIL Architecture
The VEIL architecture is a privacy-preserving ML framework built around a three-tier trust model: Trusted Tier (Source Environment), Semi-Trusted Tier (Training Environment), and Application Tier (Inference Environment). It enforces strict trust boundaries, ensuring sensitive data remains confined to trusted infrastructure. Only non-invertible, informationally-compressed latent representations cross these boundaries, preventing exposure of raw data, gradients, or identifiable attributes to untrusted environments. This naturally aligns with privacy-by-design regulatory frameworks like GDPR and HIPAA.
Non-Invertibility Guarantees
The paper rigorously proves the non-invertibility of ICA encodings in multiple reinforcing senses, combining architectural separation, mathematical non-invertibility, and information-theoretic guarantees. Topological non-invertibility is established via dimensionality reduction (E < D), showing that an injective function from a higher-dimensional space to a lower-dimensional space is impossible if the higher-dimensional space has a nonempty open subset. Information-theoretic arguments show that the encoder strictly reduces information about the original data (I(X;Z) < H(X)), leading to an irreducible uncertainty (H(X|Z) > 0) and a probability of error (Perr > 0) for any reconstruction attempt. In a realistic deployment, where the attacker has no knowledge of the encoder, the conditional entropy tends to infinity, and reconstruction probability collapses to 0.

Healthcare Data Sharing with VEIL
In a critical application domain like healthcare, secure data sharing across multiple facilities for enhanced model training is paramount. The VEIL architecture enables healthcare organizations to leverage large, diverse patient populations for ML model training without directly sharing sensitive patient information. Each medical facility maintains its Trusted Source Environment, where raw PII/PHI data is processed by a VEIL encoder to produce non-invertible latent representations. These anonymized vectors are then sent to a Shared Training & Inference Environment (Untrusted). Models trained on this pooled, anonymized data benefit from patterns observed across multiple facilities, vastly improving predictive capabilities for tasks like patient triage or readmission risk detection. This approach ensures GDPR and HIPAA compliance by design, as sensitive data never leaves the local trusted environment, while simultaneously boosting ML model performance and generalizability.
