😍 A heartfelt thanks to all the authors for their brilliant collaboration and insight throughout this work! I am very happy I had a chance to learn a lot and to contribute to this work!

Beyond privacy applications, the framework we propose may also prove useful in fault detection and observer design.
If you’re interested in geometric system theory, cyber-physical security, or system privacy, we hope this paper provides valuable perspectives and tools.

🔬This investigation deals with the fundamental geometric properties of output redundancy and of system invertibility, thus offering new perspectives on privacy protection in cyber-physical systems.

Our study introduces an output allocation synthesis problem motivated by privacy preservation: how can we “conceal” input information from a malicious eavesdropper, while still enabling legitimate reconstruction by an authorized user?

🔎 In this work, we explore output-redundant linear systems — systems with more outputs than inputs — through the lens of the geometric approach of Wonham and co-authors.

Formal guarantees – ensuring faults are caught before safety is compromised.
We also introduce the concept of τ-fault-tolerant sets, which guarantee a minimum buffer time between fault detection and the system entering an unsafe state—critical for real-time fault accommodation.

🔍 What’s new?
No full-state estimation required – we work directly with system outputs.
Noise-tolerant design – robust against process and measurement noise.
Safety-focused alarms – detect only faults that could lead to unsafe behavior.

This work builds on research we recently presented at ECC 2025, where we explored how barrier functions—commonly used for safety verification—can be reimagined as a powerful fault detection tool for safety-critical cyber–physical systems.
