PLUS-MSL-FP Database - Download Page

This is "The Multimedia Signal Processing and Security Lab", short WaveLab, website. We are a research group at the Artificial Intelligence and Human Interfaces (AIHI) Department of the University of Salzburg led by Andreas Uhl. Our research is focused on Visual Data Processing and associated security questions. Most of our work is currently concentrated on Biometrics, Media Forensics and Media Security, Medical Image and Video Analysis, and application oriented fundamental research in digital humanities, individualised aquaculture and sustainable wood industry.
PLUS-MSL-FP Database

PLUS-MSL-FP Database

In total, the PLUS Multi-Session and Longitudinal Fingerprint Database (PLUS-MSL-FP Database) consists of 108106 fingerprint samples, acquired over a time-span of 2 years from 59 different subjects. There are 4 sessions in total, the first acquisition session took place in March 2017, the second one in September 2017, the third one in March 2018 and the last one in March 2019. Hence, the entire dataset contains 4 subsets, each one containing the samples of one acquisition session. In the first two sessions 59 volunteers participated, 58 in the third and 50 in the last one. In total, we have an overlap of 50 volunteers (30 male, 20 female) who participated in all four capturing sessions, all the others are additional subjects. The subjects' age ranges from 25 to 78 and can be partitioned into four age groups: younger than 30 years (y30),older than 30 and younger than 40 years (o30y40), older than 40 and younger than 60 years (o40y60), and older than 60 years (o60).

The PLUS-MSL-FP Database was acquired with 10 different commercial off-the-shelf fingerprint capturing devices, including optical, capacitive and one thermal scanner. All of them are depicted in the figure below. The optical ones are the Lumidigm V311 (Venus), the Lumidigm M311 (Mercury), the DigitalPersona URU5160, and the Suprema RealScan G1. The first two scanners are not only optical but multispectral devices. The capacitive ones are the Integrated Biometrics Columbo (active capacitive), the Integrated Biometrics Curve (active capacitive), the Zvetco Verifi P5000, the DigitalPersona Eikon 710 Touch, the Upek Eikon II Swipe (swipe scanner) while the thermal sensor is the Next Biometrics NB-3010-U. Samples captured with these scanners result in a resolution of 500 dpi.

Filename and Directory Structure

For the entire database the following directory structure applies:
  • Scanner_XXXX: contains the fingerprint samples of the scanner the directory is named after
    • Session_Y: fingerprint samples captured at the first, second, third or fourth acquisition time
      • User_ZZ: a subdirectory for each user contained in the data set
        • Finger_AA: a subdirectory for each finger of each user contained in the data set
The filename are encoded using the following structure:
[scanner name]_[user ID]_[session ID]_[finger ID]_[image ID].png
  • scanner name: the name of the scanner used to capture the image
  • user ID: the user ID, one or two digits, where 1 denotes the first user and 70 denotes the 70th user
  • session ID: the session ID, one digit, where e.g. 1 denotes the first session
  • finger ID: the finger ID, one or two digits, starting from the left thumb (1) till the right pinky finger (10):
    • 2: left index finger
    • 3: left middle finger
    • 4: left ring finger
    • 5: left pinky finger
    • 6: right thumb
    • 7: right index finger
    • 8: right middle finger
    • 9: right ring finger
  • image ID: the image ID, one digit, starting from 1.
An example filename is: Eikon_710_Touch_37_4_9_2.png
