C# Based EEG Encryption System Using Chaos Algorithm

In the paper, we use Microsoft’s Visual Studio Development Kit and the C# programming language to implement chaos-based electroencephalogram (EEG) encryption system with three encryption levels. A chaos logic map, an initial value, and a bifurcation parameter for the map are used to generate level I chaosbased EEG encryption bit streams. Two encryption-level parameters are added to these elements to generate level II chaos-based EEG encryption bit streams. An additional chaotic map and a chaotic address index assignment process are added to implement level III chaos-based EEG encryption system. Eight 16-channel EEG Vue signals are tested using the encryption software. The encryption speed is the lowest, and encryption is most robust for the level III system. The test results show that the results of encryption are superior, and when the correct deciphering parameter is applied, the EEG signals are completely recovered. However, an input parameter error, for example, a 0.00001% initial point error, will cause chaotic encryption bit streams, and 16channel EEG Vue signals will not be recovered.
