LUTBIO multimodal biometric database
Description
The LUTBIO multimodal biometric database includes the following key features: - The database comprises nine types of biometric data: voice, face, finger, palm_touch, ECG, opisthenar, ear, palm_touchless, and periocular. - The database includes information on 306 subjects, with a balanced gender ratio of 162 males and 143 females. The age distribution is wide-ranging, from the youngest at 8 years old to the oldest at 90 years old. - The volunteers for the database come from naturally occurring human settlements, representing a large-scale statistical population. The collected biometric data reflects various changes in real-world environments. - The LUTBIO database provides both palm print (contact-based and contactless) and fingerprint (optical photos and scans) biometric information, aiming to promote the development of multimodal biometric authentication technologies and guide the creation of future multimodal biometric databases. - The biometric data in the LUTBIO database is highly decoupled, meaning that these data can be separated and independently processed without losing their original information. This provides flexibility for analyzing and improving single or multimodal recognition technologies, while also allowing researchers to optimize or recombine different biometric features for specific application scenarios. ✅✅✅Given that the paper has not yet been published, we have decided to upload sample data from 6 individuals first. Once the paper is published, we will release the entire dataset. 🥸🥸🥸Please read the collection protocol of the LUTBIO data set carefully, which is very important to us. Thank you.

Steps to reproduce
The LUTBIO multimodal biometric database was collected over a period of four months, divided into two phases. The first phase involved collecting data from 209 individuals, and the second phase from 98 individuals. In total, more than 11,000 images and 1,000 lossless voice wav files were collected. For the collected biometric data, we performed data anonymization and naming operations. The naming format we designed is as follows: volunteer ID_gender_age group_biometric modality_file number. For example, the fingerprint image "012_male_56_finger_10.bmp" represents the 12th volunteer, male, aged between 50 and 60, fingerprint biometric modality, and is the 10th bmp format fingerprint image of this volunteer. Similarly, the voice file "074_female_78_voice_02.wav" represents the 74th volunteer, female, aged between 70 and 80, voice biometric modality, and is the 2nd wav format audio file of this volunteer. This protocol clarifies that the data collection for the LUTBIO Multimodal Biometric Database was conducted at natural residential locations within China (specific locations remain confidential). To protect the volunteers' data security, the collection sites were equipped with stringent security measures, including surveillance cameras, data encryption, and access restrictions. Only researchers who have applied and agreed to a strict confidentiality agreement can access the data. This data is solely for research purposes and must not be used for commercial or illegal activities. Furthermore, all data has been anonymized to ensure the maximum protection of volunteers' privacy. The data will be stored on secure servers with regular backups and updates. Researchers have submitted data management reports to relevant Chinese regulatory authorities to ensure legal use and fair review of the data. The multimodal biometric data presented in the paper will not be from the same individual, further protecting the volunteers' privacy. Before data collection, each participant must sign an informed consent form, detailing the use of personal information and data transfer restrictions. Participants have the right to access, correct, or delete their data. For minors, their legal guardians must also sign the consent form. Researchers will reiterate these rights during the data collection process to ensure participants fully understand and can exercise these rights at any time. Volunteers can withdraw their data usage permission at any time, and any violation of data protection principles will be severely sanctioned. Through these measures, the LUTBIO Multimodal Biometric Database will become an essential resource for biometric technology research.
