Where DNA Shield fits
Four use cases for the small, irreplaceable information an organization cannot afford to lose, led by key custody continuity.
Key custody continuity
Critical keys are already backed up.
The challenge is whether the scheme that recovers them still works years later, after the people and vendors around it have changed. Recovery usually depends on a secret split into shares held by several custodians, where a defined number must come together to rebuild it. The mathematics is settled. The people are not: custodians leave, vendors change, records drift, and the quorum is rarely tested. DNA Shield is designed to hold one distributed, offline share along with the records and instructions needed to reconstitute the scheme, so recovery survives turnover and vendor change. It is designed to complement a certified HSM, not to replace one. Qualification is underway.
How it is deployed
Customers protect one key domain at a time under managed custody. DNA Shield is designed to safeguard a wrapped key component or a single threshold share, distributed across trusted custodians and locations, alongside the information needed for long-term recovery. It complements certified HSMs and existing key management infrastructure rather than replacing them.
Crown jewel industrial IP
Some industrial knowledge cannot simply be recreated.
Proprietary formulations, manufacturing processes, calibration data, critical design parameters and the documentation that makes them usable. Although small in size, these digital trust assets are often essential to restoring operations after a cyber incident. DNA Shield is designed to preserve an approved, offline copy under sovereign managed custody, physically separated from the production systems it supports. Rather than backing up everything, it protects the small set of information an organization cannot afford to lose. Durability and tamper evidence are design goals currently under qualification.
Deployment model
The information protected is typically measured in kilobytes or a few megabytes rather than gigabytes. Examples include master formulations, manufacturing recipes, calibration datasets, cryptographic signing information for industrial control systems, process parameters, engineering reference files and the accompanying documentation needed to interpret them correctly. DNA Shield is intended for curated recovery packages rather than complete engineering repositories or operational datasets.

Regulated integrity
Many regulated industries must preserve records that can be trusted years or even decades after they were created.
While compliant archives are designed for retention and retrieval, organizations may also need to demonstrate that critical records have not been altered since approval. DNA Shield is designed to preserve an approved integrity package offline, under sovereign managed custody and physically separated from operational systems. It complements existing archives by providing an independent source of trust rather than replacing compliance or document management platforms. Tamper evidence and long-term durability are design goals currently under qualification.
Deployment model
There are many regulatory frameworks that require organizations to preserve trusted records, far too many to list individually. Typical examples include approved clinical trial protocols and statistical analysis plans in life sciences, financial risk model artifacts in banking, engineering approval packages, audit evidence, digital forensic evidence, and critical compliance records. These integrity packages are typically small, ranging from approximately 50 KB to 500 KB.
Sovereign memory
Some records must remain trustworthy not just for years, but for generations.
National archives, constitutional documents, land registries and other golden records may outlive the organizations, systems and technologies that created them. Their combination of small size, high value and infrequent access makes them particularly well suited to DNA-based storage. DNA Shield is designed to preserve these irreplaceable digital trust assets offline, under sovereign managed custody and physically separated from operational infrastructure.
Deployment model
Examples include constitutional and treaty documents, national register indexes, cultural heritage archives, foundational scientific datasets, and other golden records that require long-term preservation and infrequent access. These information packages are typically small but irreplaceable, rarely changed or accessed, making them well suited to DNA-based storage. Biomemory's underlying technology was demonstrated in 2021 when two founding texts were preserved in DNA through research led by CNRS and Sorbonne University. This work represents the scientific foundation of the technology rather than a commercial deployment.
How it is deployed
Unlike the near-term commercial use cases, sovereign memory is expected to be adopted through institutional programs, national archives, research initiatives and public sector procurement. DNA Shield is intended to preserve carefully curated golden records that must remain authentic and recoverable over decades or centuries, complementing existing archival systems rather than replacing them.
