Every year, during high school and college entrance exams, news of impersonation and cheating emerges. Some people forge IDs, some disguise themselves, and some even make silicone fingerprint covers. How can we stop these cheating methods?

Currently, many exams rely mainly on facial recognition. But faces have a natural weakness – they are almost "open-source data." Your face is everywhere: on social media, street cameras, security checkpoints – easily captured and copied. AI face-swapping and 3D-printed masks are no longer new. Relying solely on facial recognition leaves security gaps.

So what about adding fingerprints?

Fingerprints are not as publicly exposed as faces. More importantly, fingerprint technology can not only verify identity but also determine whether the finger belongs to a living person. This is the key to "detecting fakes."

Ordinary fingerprint scanners only read the pattern; they cannot tell a real finger from a silicone cover. A new generation of glass-based infrared fingerprint technology gives the scanner a "life detector." Using the light-transmitting property of glass, it integrates an infrared emitter and receiver. When a finger presses down, infrared light detects subcutaneous life signals such as blood flow. Fake fingers have no such signals, so the device rejects them immediately.

If this technology were adopted in exam halls, a single press would accomplish two things: verifying the fingerprint pattern and confirming it's a real human finger. Even if a cheater obtains a candidate's fingerprint data and customizes a silicone cover, they cannot simulate life signals – the fake would be caught on the spot.

Facial recognition works well for quick initial screening, while fingerprint serves as the ultimate confirmation. The combination adds a physical-level defense for exam fairness.

Chipsailing focuses on glass-based fingerprint recognition technology, making fake fingerprints nowhere to hide and safeguarding fairness for every student who studies hard.
