The recent advancements in brain-computer interface (BCI) research have been marked by a significant shift towards enhancing both the functionality and security of these systems. A notable trend is the integration of deep learning models, which have demonstrated superior performance in tasks such as imagined speech state classification and visual stimuli decoding from EEG signals. These models, such as EEGNet, have shown enhanced ability in automatic feature extraction and representation learning, essential for capturing complex neurophysiological patterns. Additionally, there is a growing emphasis on privacy and security in BCIs, with innovative approaches like identity-unlearnable EEG data conversion and backdoor attack prevention in transfer learning models. These developments aim to protect user identity and prevent malicious attacks that could compromise the integrity of BCI systems. Furthermore, the field is witnessing advancements in multimodal data utilization, exemplified by frameworks like CognitionCapturer, which leverage cross-modal information to improve the accuracy of visual stimuli decoding. This approach not only enhances the performance of BCIs but also opens new avenues for research in integrating diverse data types. Overall, the current direction of BCI research is towards creating more robust, accurate, and secure systems that can effectively decode brain signals while safeguarding user privacy and data integrity.
