摘要：
Based on parameter identification, an observer is presented to identify the unknown parameter of hyperchaotic Chen system, then the useful information modulated in the parameter can be recovered successfully. In the improved scheme, an approximate observer is adopted for more security. Numerical simulations show the effectiveness of our method.
