Vkansee demonstrates fingerprint spoofing with clay mold at MWC

Vkansee, a fingerprint sensor manufacturer from China, demonstrated at Mobile World Congress how a fake fingerprint can fool a smartphone’s fingerprint sensor.

In a video report by the BBC, Vkansee president Jason Chaikin showed how a clay mould was able to fool an existing fingerprint sensor on a smartphone because, according to Chaikin, the sensors weren’t high resolution enough.

Vkansee took the opportunity to discuss of how its own optical fingerprint sensors can provide a far greater performance, capturing fingerprints at a resolution of 2000 dpi.

The company recently released its VK0208 sensor, which is designed for integration with leading PC and smartphone manufacturers and can capture fingerprint images at a high resolution of 2,000 pixel-per-inch (PPI), in contrast to current industry standard sensors which only reach 500 PPI.

The new sensor has a 6.0 x 3.5 mm active area, is only 1.5 mm thin and operates under 0.4 ~ 0.8 mm cover glass. The VK0208 supports third-level feature recognition, which means it captures microscopic sweat pores, ridge textures and other micro-features of the fingerprint, in addition to the usual ridge flow patterns and minutiae in second level feature recognition.

In a recent interview with BiometricUpdate.com, Chaikin stated, “The high resolution means higher security, because there is more data to discriminate between real and spoofed fingerprints, which is a growing concern for winning consumer confidence.”
