A major integrative effort within the BioSecure Network of Excellence lies with the design and collection of a new multimodal database.

The BioSecure database has been designed to include data corresponding to face, voice, iris, fingerprint, palm print and signature modalities, within the framework of three datasets corresponding to real multimodal, multi-session, multi-environment situations.

Moreover, to increase the representativeness of the database, BioSecure participants agreed to collect the above mentioned data in a variety of sites (11 at the end) involving a number of countries spread over Europe. Not all the centers contributed to the acquisition of the three datasets. Nevertheless, each acquisition center completed for about 100 individuals the acquisition of the whole set of data (two sessions per person) for the datasets they were in charge.

The three datasets have the following characteristics: 

• Dataset DS1 (PC-based, on-line, Internet environment, unsupervised conditions•)

• Modalities included: voice, face;
• Donors: 971;
• The main purpose of DS1 is to have material collected over the Internet and under uncontrolled situations. In this way, a broad target population can be reached and a quite realistic database can be acquired. The first session was necessarily guided. For the second session, the donor had the opportunity to use any Internet connection (from home, work, ...).

• Dataset DS2 (PC-based, off-line, desktop environment, supervised conditions):

• Modalities included: voice, face, signature, fingerprint, hand and iris;
• Donors: 667;
• The scenario considered for the acquisition of DS2 is a PC-based offline supervised scenario. It consists of an office room, with a wide desktop for the acquisition hardware and two comfortable chairs for the supervisor and the contributor.
• The acquisition hardware includes a standard PC machine and a number of data acquisition sensors connected to the PC via USB or Bluetooth interfaces.

• Dataset DS3 (mobile device-based, indoor/outdoor environment, uncontrolled conditions):

• Modalities included: voice, face, signature and fingerprint;
• Donors: 713;
• The objective of this dataset is to have a multimodal database with several modalities acquired on current mobile platforms. For audio-video recordings two different acquisition conditions are considered: indoor and outdoor, with sources of variability for each modality. For signature and fingerprint recordings only one degraded acquisition condition is considered, because controlled quality data are recorded in DS2.
  
• Hardware devices used for the acquisition include a PDA HP iPAQ hx2790 (for fingerprint and signature) and a Mobile PC SAMSUNG Q1 + Web Cam (for face and voice).
