An EEG identity authority control system and method

Abstract

Embodiments of the present invention provide an EEG identity authority control system and method. The system consists of an interconnected brain-computer Interface Device, an Authority Processor and aPeripheral Device, wherein, the Brain-computer interface device is used for acquiring the EEG signal in the process of the user manipulating the external equipment, and converting the EEG signal intothe manipulation instruction which can be recognized by the external equipment; the computer interface device is used for acquiring the EEG signal in the process of the user manipulating the externalequipment, the Authority processor is used for extracting EEG features from EEG signals and determining user manipulation privileges based on the extracted EEG features, and the Peripheral Device isused for determining whether to execute a manipulation behavior with a permission request indicated by the manipulation instruction according to the manipulation authority. Thus, the EEG features areextracted from the EEG signals obtained in the process of the user manipulating the external device to perform the identification right confirmation, thereby realizing the corresponding identificationright control for the manipulation of the external device with the permission requirement, without the need of the additional identification right confirmation time, and thereby improving the efficiency of the identification right confirmation.

Description

technical field [0001] The present invention relates to the technical field of brain-computer interface, and more specifically, to a system and method for controlling brain-electricity identity rights. Background technique [0002] Biometrics-based identification has always attracted the attention of scientists. Scientists believe that biometrics, such as fingerprints, irises, faces, and brain activities, have inter-individual specificity and long-term stability. But at the same time, the emergence of various biometric forgery methods has seriously threatened the security of the biometric system. Compared with other forms of biometrics, authentication / identification methods based on EEG signals are more secure and reliable. [0003] However, in the current method for confirming the identity and authority of the EEG signal, there are the following problems: because the signal-to-noise ratio of the EEG (Electroencephalograph, referred to as EEG) signal is generally low, it ta...

Problems solved by technology

[0003] However, in the current method for confirming the identity and authority of the EEG signal, there are the following problems: because the signal-to-noise ratio of the EEG (Electroencephalograph, referred to as EEG) signal is generally low, it takes a long time to collect the signal for accumulation to improve the SNR, thereby As a result, the identity and authority confirmation operation based on EEG signals takes a long time to complete, and it is difficult to meet the requirements for the efficiency of identity authority confirmation in practical application scenarios
