The fingerprint image is captured, stored, and matched entirely within the secure, encapsulated sensor.
As of the current market cycle, while Synaptics has shifted some focus to optical and ultrasonic sensors (in partnership with others), the FS7605 remains in production due to high demand from security-sensitive industries. The PurePrint™ algorithm continues to receive over-the-air updates via host drivers, meaning deployed devices get smarter over time as Synaptics trains its neural network on new spoof methods.
The Synaptics FS7605 is a touch-based fingerprint sensor designed primarily for the mobile, tablet, and laptop markets. Unlike older swipe-style sensors that required a user to drag their finger across a surface, the FS7605 utilizes a static touch area. This allows for a more intuitive user experience, mimicking the natural action of pressing a button.
The FS7605 is more than a simple capture device; it is a complete security subsystem. The internal flash memory is used exclusively for storing fingerprint templates. The sensor also utilizes a hardware-accelerated encryption engine that supports TLS 1.2 and AES-256 encryption. This engine can encrypt communication between the sensor and the host system, preventing any potential interception of the biometric data. synaptics fs7605 touch fingerprint sensor with pureprint-tm-
Artificial materials like rubber, latex, or wood glue have drastically different electrical impedance profiles compared to live human tissue. PurePrint™ checks these dynamic electrical properties during the sub-second scan.
This technology addresses two critical challenges:
The standout feature of this sensor is . This isn't just a marketing buzzword; it's a sophisticated anti-spoofing layer designed to differentiate between a real human finger and a fraudulent attempt. The fingerprint image is captured, stored, and matched
Moreover, Synaptics has designed PurePrint to be a . The drivers for the FS7605 sensor are regularly updated, and the PurePrint algorithm is constantly refined with new data to identify and defend against emerging spoofing techniques and materials. This ensures that the security solution on a device featuring the FS7605 remains effective against the latest threats, providing long-term, future-proof protection for end-users.
: Uses unique artificial intelligence to analyze fingerprint images and distinguish between actual live fingers and fake or spoofed materials like silicone or plastic.
The Synaptics FS7605 operates within the Windows Biometric Framework (WBF) , acting as a secure hardware endpoint communicating over a high-speed internal USB bus link. The Synaptics FS7605 is a touch-based fingerprint sensor
Connects via the Universal Serial Bus (USB) architecture.
In an era dominated by sophisticated cyber threats and identity theft, traditional password-based authentication is no longer sufficient. Biometric authentication—specifically fingerprint scanning—has become the gold standard for securing smartphones, laptops, and enterprise endpoints. However, as biometric adoption grows, so does the sophistication of spoofing attacks, where bad actors use artificial materials like silicone, gelatin, or 3D-printed molds to bypass scanners.
The FS7605 is a system-on-chip (SoC) that includes more than just an image scanner. The sensor is built around a 192 MHz processor, which serves as the central processing unit for all internal operations. In addition to the processor, the FS7605 is equipped with:
