英文摘要：

The research progress of encryption technologies based on human biometrics is reviewed in this paper. The technologies that utilize human biometrics to make information encryption and identity authentication, and the technologies which combine bio-metrics encryption with optical encryption methods are introduced in detail. The advantages and disadvantages of these encryption systems are discussed,and the obstacles in practical applications are pointed out. Finally,the prospect of the new encryption tech-nologies that are based on human biometrics are predicted.
