Can Your Smart Lock Be Spoofed? How KAADAS Addressed Forgery Risk
Palm vein recognition is an AI-powered contactless biometric that reads sub-dermal vascular patterns — hidden beneath the skin and impossible to forge. KAADAS, a long-term Tencent Cloud partner in the smart lock ecosystem, integrates PalmAI's palm vein algorithm into its product portfolio, delivering stronger anti-spoofing protection and more stable recognition than surface-based biometrics.

Why Anti-Spoofing Matters More Than Ever for Home Locks
KAADAS is one of China's leading smart lock manufacturers, known for premium build quality and advanced biometric features. As smart locks proliferate in Chinese households, a growing concern emerges: how easy is it to fool the lock?
Security landscape for home locks:
| Threat vector | Fingerprint lock vulnerability | Face lock vulnerability |
|---|---|---|
| 3D replica / silicone mold | Can bypass many consumer sensors | Not directly applicable |
| Photograph / video | Not applicable | Can fool basic 2D face detection |
| Lifted prints from surfaces | Fingerprints left on every surface touched | Not applicable |
| Covert capture without consent | Fingerprints can be collected unknowingly | Faces photographed in public |
| Condition-dependent failure | Wet/dry/worn hands cause lockouts | Low light / strong light affects accuracy |
KAADAS identified that surface biometrics — both fingerprint and face — share a fundamental weakness: they can be observed, captured, or replicated externally. Palm vein patterns solve this by existing beneath the skin, invisible to any camera or sensor that doesn't use active near-infrared illumination at close range.

Palm Vein vs Fingerprint vs Face: Anti-Spoofing Comparison for Door Locks
| Anti-Spoofing Dimension | Fingerprint | Face Recognition | Palm Vein |
|---|---|---|---|
| Can biometric be captured without consent? | Yes — prints left on every surface | Yes — face photographable in public | No — requires active IR at 3–5cm + willing hand |
| Can biometric be replicated? | Yes — silicone/3D print replicas documented | Yes — high-res photos, 3D masks | No — sub-dermal patterns invisible to all cameras |
| Condition-dependent failure | Wet/dry/worn → lockout | Low light / sunglasses / masks → failure | None — works in all conditions |
| Privacy risk if lock hardware stolen | Stored templates potentially reversible | Stored facial data highly sensitive | Encrypted vein template; non-reversible |
| Covert enrollment possible? | Yes — sleeping person's finger | Yes — photo taken without knowledge | No — requires intentional open-hand gesture |
When fingerprint still has an edge: For households primarily concerned with cost rather than security, fingerprint locks are available at lower price points. KAADAS positions palm vein in its premium tier for users who prioritize anti-spoofing above all else.
How PalmAI Powers KAADAS's Anti-Spoofing Lock Technology
Tencent Cloud and KAADAS have worked closely for years within the smart lock ecosystem. Leveraging Tencent's long-term expertise in palm vein recognition algorithms and production-grade deployment, PalmAI provides the core biometric engine for KAADAS's smart lock lineup with palm vein recognition.
Technical implementation:
| Component | Detail |
|---|---|
| Biometric modality | Palm vein (sub-dermal near-infrared) |
| Algorithm foundation | Tencent YouTu Lab — years of palm vein research + optimization |
| Processing | On-device edge computing |
| Recognition speed | < 0.8 seconds |
| Anti-spoofing | Sub-dermal patterns — immune to photos, replicas, lifted prints |
| Privacy architecture | No facial data captured; palm data stored on-device only |
Why KAADAS chose palm vein over other modalities:
- Strongest anti-spoofing available — unlike fingerprint (surface) or face (external feature), palm veins are internal signals that require active IR illumination + willing hand presentation to read
- Superior to face recognition on privacy — no facial data collected, no photos stored, no possibility of covert capture
- Stable across conditions — unaffected by lighting, skin moisture, aging, or cosmetic changes
- Differentiation in crowded market — palm vein positions KAADAS above fingerprint-only competitors on security claims
KAADAS Results: What Palm Vein Delivers for Home Security
| Dimension | Fingerprint Lock | KAADAS Palm Vein Lock (PalmAI) |
|---|---|---|
| Spoofing resistance | Vulnerable to replicas | Sub-dermal, unforgeable |
| Covert data capture | Fingerprints left everywhere | Palm vein invisible without IR |
| Privacy concern | Moderate | No facial data, no external biometrics |
| Condition stability | Fails with wet/dry/worn skin | Stable regardless of condition |
| Family differentiation | Basic | Distinguishes all members |
| User feedback | Frequent frustration with failures | Broad positive feedback |
What's Next for KAADAS and PalmAI
As user expectations for security and privacy continue to rise, KAADAS is expanding palm vein recognition across its full product range. The shift from fingerprint to palm vein represents a broader industry movement toward sub-dermal biometrics — where the credential is invisible, non-transferable, and inherently private.

FAQ
How does KAADAS's smart lock with palm vein prevent spoofing compared to fingerprint?
KAADAS smart locks with palm vein use Tencent PalmAI's near-infrared technology to read vascular patterns beneath the skin. These patterns cannot be photographed, lifted from surfaces, or replicated with silicone — because they are invisible without active IR illumination at 3–5cm distance. A potential intruder cannot capture your palm vein pattern the way they can lift a fingerprint from a glass or door handle.
Is palm vein recognition more private than face recognition door locks?
Yes. Palm vein recognition captures only internal vascular patterns using infrared — no facial photograph is taken, no image is stored, and the biometric cannot be captured covertly in public. Unlike face recognition locks that use cameras, palm vein requires the user to intentionally present their open hand at close range, making non-consensual capture technically impossible.
How long has Tencent Cloud worked with KAADAS on palm vein technology?
Tencent Cloud and KAADAS have maintained a multi-year deep collaboration in the smart lock space. This long-term partnership means KAADAS products benefit from continuous algorithm refinement, field-tested performance optimization, and production-grade reliability that newer entrants to palm vein cannot match.
Will palm vein recognition work for elderly family members?
Palm vein patterns remain stable throughout a person's lifetime because they are internal vascular structures unaffected by skin aging, dryness, or calluses. Unlike fingerprint sensors that struggle with elderly users' worn fingerprints, PalmAI's palm vein recognition works reliably for ages 8–100.
Does the KAADAS smart lock with palm vein need internet to function?
No. PalmAI Lock processes all recognition on-device. The lock works without any network connection, and palm data never leaves the hardware — addressing both privacy concerns and connectivity reliability.
