Data Confidentiality: Ensuring data security with zero leakage of customer information

As InSAR technology transitions from research to commercial applications, data confidentiality has become an industry-critical issue - millimeter-level deformation data not only safeguards engineering integrity but also encodes digital keys to national infrastructure security and corporate core competitiveness.

InSAR Data Sensitivity: From Pixels to National Security Cryptography

  1. Geospatial Resolution:

    Modern SAR satellites (e.g., TerraSAR-X) achieve 0.25m resolution, capable of detecting airport runway cracks or oil pipeline weld displacements.

  2. Time Series Correlation:

    Continuous monitoring data can reverse-engineer construction timelines of critical facilities or strategic material reserve fluctuations.

  3. Cross-domain Information Integration:

    Atmospheric delay correction using meteorological satellites may inadvertently expose sensitive regional meteorological parameters.

Confidentiality Technologies for InSAR Data Lifecycle

  1. Storage Encryption

    Client project data encrypted with AES-256 algorithm, key management compliant with mainstream standards. Sentinel-1 satellites are suitable for rapid deformation monitoring with short temporal baselines (<84 days, e.g., earthquakes), while L-band satellites (e.g., ALOS-2) with long temporal baselines (>360 days) better suit gradual crustal movement analysis.

  2. Adversarial Data Anonymization

    Application of ±0.3mm/year Gaussian noise to sensitive area deformation data, compliant with IEEE Earth Observation Ethics Standards.

  3. Multi-layered Isolation

    Differential access controls across processing stages, data blocks stored on air-gapped internal servers.

Process Security

  1. Analysis Phase

    Implementation of 'Triple Isolation' principle: development vs production environments isolation, test vs real data isolation, internal vs external network isolation.

  2. Delivery Phase

    Secure Multi-party Computation (MPC) technology enables clients to verify results via zero-knowledge proofs without accessing raw data.

  3. Transmission Encryption

    TLS 1.2 protocol ensures data security during internet transmission.


"Data security supersedes all. We commit to never disclosing client information, contractually and procedurally enforced."

In the digital era, information protection capability has become the gold standard for valuing geospatial enterprises - it demonstrates both technical prowess and business ethics. Through our dual 'Technology-Process' security architecture, we are redefining InSAR industry safety benchmarks.
