Multi-identity Information Authentication EEG Dataset

An ERP Dataset for Multi-Information Identity Authentication

This dataset contains EEG recordings collected from 32 healthy adult participants during a multi-information identity authentication experiment. The participants included 16 males and 16 females, aged between 19 and 25 years. The experiment was designed to investigate RSVP-based EEG responses to different identity-related stimuli.

Each participant completed three identity-related recognition tasks:
1. Face recognition task
2. Name recognition task
3. Verification-image recognition task

Each participant completed two independent sessions, labeled ses-01 and ses-02. Each session contains EEG recordings for the three tasks. In each task, visual stimuli were presented using a rapid serial visual presentation (RSVP) paradigm at 10 Hz. Each stimulus was presented for 100 ms.

EEG signals were recorded using a portable TiTan EEG system at a sampling rate of 1000 Hz. Eight scalp EEG channels were used:
Fpz, F3, F4, FCz, POz, O1, Oz, and O2.

The dataset is organized according to the Brain Imaging Data Structure (BIDS) format.

Each participant folder contains two session folders:

sub-XX/

eeg/
ses-02/

Each EEG folder contains BrainVision EEG files and BIDS metadata files for each task and run:

sub-XX_ses-YY_task-face_run-ZZ_eeg.vhdr
sub-XX_ses-YY_task-face_run-ZZ_eeg.vmrk
sub-XX_ses-YY_task-face_run-ZZ_eeg.eeg
sub-XX_ses-YY_task-face_run-ZZ_events.tsv
sub-XX_ses-YY_task-face_run-ZZ_channels.tsv
sub-XX_ses-YY_task-face_run-ZZ_eeg.json

The same naming structure is used for the name recognition task and the verification-image recognition task.

Task labels:
task-face: face recognition task
task-name: name recognition task
task-verification: verification-image recognition task

Session labels:
ses-01: first experimental session
ses-02: second experimental session

The EEG recordings are provided in BrainVision format. The .eeg file contains the continuous EEG signal, the .vhdr file contains header information, and the .vmrk file contains marker information. The events.tsv files provide event onset times, durations, sample indices, and event types. The channels.tsv files provide EEG channel information. JSON sidecar files provide task and recording metadata.

Target labels

For the target/non-target classification task, the target label is defined according to the task type.

For the face recognition task, the target label is 1 for all participants.

For the name recognition task, the target labels are:
sub-01: 16, sub-02: 2, sub-03: 1, sub-04: 5, sub-05: 5, sub-06: 6, sub-07: 7, sub-08: 8, sub-09: 9, sub-10: 10, sub-11: 1, sub-12: 12, sub-13: 13, sub-14: 14, sub-15: 15, sub-16: 16, sub-17: 2, sub-18: 3, sub-19: 4, sub-20: 20, sub-21: 19, sub-22: 2, sub-23: 6, sub-24: 14, sub-25: 10, sub-26: 19, sub-27: 11, sub-28: 16, sub-29: 13, sub-30: 20, sub-31: 15, sub-32: 9.

For the verification-image recognition task, the target labels are:
sub-01: 16, sub-02: 2, sub-03: 1, sub-04: 5, sub-05: 5, sub-06: 6, sub-07: 17, sub-08: 8, sub-09: 9, sub-10: 10, sub-11: 11, sub-12: 12, sub-13: 13, sub-14: 14, sub-15: 15, sub-16: 16, sub-17: 2, sub-18: 18, sub-19: 4, sub-20: 20, sub-21: 1, sub-22: 2, sub-23: 6, sub-24: 17, sub-25: 18, sub-26: 16, sub-27: 17, sub-28: 13, sub-29: 11, sub-30: 12, sub-31: 19, sub-32: 20.

All target labels are anonymized numeric labels. They do not contain real names, facial identities, or other personally identifiable information.

This dataset can support research on event-related potential (ERP) analysis, RSVP-based target detection, EEG-based identity authentication, cross-session evaluation, and machine learning or deep learning methods for brain-computer interface applications.
