Prove identity
Surface and sub-surface biometric recognition.
ID4US verifies the human, not only the credential. One touch combines identity, liveness and physical presence for high-assurance authentication.

Surface and sub-surface biometric recognition.
Blood-flow sensing confirms that a living person is present.
In-depth structural analysis makes spoofing materially harder.
One integrated hardware and software platform for multiple products and security levels.
Protecting the core technology platform.
Independently assessed biometric security.
FRR below 3%
USB-C, PCIe, MIPI and more.
ID4US combines complementary biometric and physiological signals that are materially harder to reproduce than a surface pattern alone.
High-performance capture, including dry or worn fingers, with a familiar user gesture.
Structures below the skin add attack resistance that is built into the sensing physics.
Physiological activity proves that a living human is present at the moment of action.
A distinctive vascular signature extends the platform toward ultra-high-assurance workflows.

Surface identity, sub-surface anatomy, physiological liveness and microvascular signatures converge into a single trust decision. Security no longer depends on matching a fingerprint. It depends on proving the presence of a living human.
A hardware and software platform for manufacturers, integrators and trusted-device ecosystems.
Start with a working ID4US platform, validate the use case, tune the assurance level and prepare the path to embedded integration.

Use the USB-C platform to prove value quickly, then transition to an embedded module adapted to the target device and security workflow.
Compact architecture, low-power design and standard USB-C, PCIe and MIPI interfaces support integration into devices, access systems and trusted platforms.




ID4US is designed for high-value actions where impersonation, spoofing or credential sharing creates material risk.

Critical infrastructure, data centers, government, airports, industry and defense.

High-value approvals, treasury operations, multi-party authorization, wallet access and custody operations.

Secure entry, driver identity, fleets, personalization and future physiological sensing.

Laptops, terminals, access modules and embedded platforms requiring human assurance.

View eventID4US develops a 4D ultrasound biometric platform that combines surface fingerprint, sub-surface anatomy, physiological liveness and microvascular signatures into a single trust decision.
Founded in 2022 by serial entrepreneur Christophe Bernard and based in the Grenoble area and Tours, ID4US brings together 40 experts in ultrasound sensing, semiconductors, embedded systems, software, AI, materials and biometric algorithms. The company is supported by a couple of dozen patents protecting its core technology platform.
As a B2B technology provider, ID4US works with OEMs, integrators and strategic partners to move from proof of concept to embedded deployment across physical access, banking and finance, automotive and trusted digital devices.

Core facts about ID4US technology, evaluation and integration.
ID4US combines biometric identity, physiological liveness and physical presence verification in one trust decision.
The platform captures complementary surface, sub-surface tissue, blood-flow and microvascular signals rather than relying on a surface fingerprint alone.
Partners can start with the functional DeepScan USB-C hardware and software platform, validate a use case and then move toward embedded integration.
ID4US can be integrated into physical access systems, banking and financial workflows, vehicles, laptops, terminals, keyboards and other trusted digital devices.
ID4US is creating a new biometric trust architecture that combines identity, liveness and physical presence in a single embedded platform.
