Time Clocks

Your Privacy is Safe with Biometric Time Clocks

Concerned about privacy with biometric technology? With Time Clock Market’s devices, you can relax.

All time clock users can rest assured that their privacy is intact. Time and attendance devices do not capture and store a full fingerprint or facial image, so it is virtually impossible to replicate. The technology utilizes a digital process that measures the distance and angles of the lines in your fingertips or the distance between your facial features.

Fingerprint and Facial Recognition for the Workplace
Unlike the technology used by Automated Fingerprint Identification Systems (AFIS) for law enforcement purposes, Time Clock Market’s devices collect only a small subset of sample data (aka minutiae points), convert it into binary data using mathematical algorithms and then store only a digital representation of the fingerprint or face (not an actual image). Having only minutia data makes it nearly impossible to recreate the original image.

Bottom line: There are no privacy issues related to biometric identification and verification.

Significant differences between AFIS devices and Time Clock Market devices include:

Image vs. Minutia Analysis
Time Clock Market devices rely upon only minutia data and not the actual image of the scanned fingerprint or face. Conversely, AFIS-type devices use facial images and the entire rolled fingerprint image containing the ridge patterns of the fingerprint.

Image size
Time Clock Market devices use small optical sensors. AFIS devices require a full measure of the fingerprint, which is typically a rolled fingerprint image. The same is true for facial images.

No fingerprint or facial image is saved
Fingerprint and facial images are converted to mathematical representations BEFORE storing.

Incompatible with AFIS technology
Because of the different resolution, fingerprint/facial size, and image enhancement processes of the two technologies, the fingerprint and facial data collected by a time clock is virtually unusable by AFIS.
