Parallel Encryption Method on Brain Wave for a Person Authentication

In this paper, we proposed an efficient parallel encryption scheme on brain wave for user authentication using the chaos maps and junk data. Two different methods were proposed. The first method uses the fixed block size of brain wave and uses variable block size of junk data. The second method uses variable block size of brain wave and variable block size of junk data. Two methods are same processing phase. The only difference is the block size of brain wave. Especially, the person authentication using unstructured data requires the real-time processing. And many researchers have been developed the encryption method with fixed maps. However, it has better security that variable maps are used for generating the random number in chaos maps. And we developed a parallel encryption method using the threads. To execute two encryption schemes, two threads are created. The one manages the process that generates five phase chaos maps and another thread manages the encryption scheme. The processing phase of the encryption scheme is composed of five phase. As a result, the encrypted brain-wave signals are produced well and the processing time for authentication is reasonable in real-time.
