Embodiment
[0053] The present invention is realized by the following technical solutions, please refer to figure 1 , a brain-computer interface acquisition device based on blockchain, including a signal generation end, a signal encryption end, and a signal analysis end, the signal generation end is used to generate EEG signals after visual stimulation, and transmit the EEG signals to the signal encryption end The signal encryption end encrypts and compresses the EEG signal through the blockchain network, and decrypts the EEG signal according to the decryption request initiated by the signal analysis end; the signal analysis end can view the EEG signal. During the analysis, a decryption request is sent to the signal encryption terminal through the blockchain network, and the EEG signal can be analyzed after the decryption is successful.
[0054] please continue figure 1 , the signal generating end includes a user visual stimulation module, a brain-computer signal source module, and a bra...

The invention relates to a brain-computer interface acquisition device and method based on a block chain, electronic equipment and a signal generation end, and is used for generating an electroencephalogram signal after visual stimulation and transmitting the electroencephalogram signal to a signal encryption end; the signal encryption end is used for encrypting and compressing the electroencephalogram signal transmitted by the signal generation end through a block chain network, and decrypting the electroencephalogram signal according to a decryption request initiated by the signal analysis end; and the signal analysis end is used for checking the electroencephalogram signal, initiating a decryption request to the electroencephalogram signal encrypted by the signal encryption end through the block chain network, and analyzing the electroencephalogram signal after successful decryption. The signal analysis end can check the electroencephalogram signals, but when the electroencephalogram signals need to be analyzed, a decryption request needs to be initiated to the signal encryption end through the block chain network, the electroencephalogram signals can be analyzed only after decryption succeeds, and the problem of privacy leakage in the brain-computer interface data collection process is solved.
Description
technical field [0001] The invention relates to the technical field of brain-computer interfaces, and in particular, to a block chain-based brain-computer interface acquisition device, method, and electronic equipment. Background technique [0002] In the 1990s, brain-computer interface research technology achieved phased breakthroughs. Especially since 2014, many technology giants have vigorously promoted the concept of brain-computer interface. Technology giants such as IBM, Qualcomm, and Facebook have entered the brain-computer interface industry layout, making the brain-computer interface. The scale of the industry continues to expand. In a typical case, in April 2021, Musk's brain-computer interface company Neuralink demonstrated the latest research breakthrough. By implanting a brain-computer interface, a monkey can play video games with brain ideas. [0003] According to the official definition of the first BCI International Conference, a brain-computer interface (BC...
