Abstract: The security of fingerprint technology itself is becoming increasingly prominent with its wide use in intelligent terminal device.With the security extension mechanism of ARM TrustZone,the technique and method of fingerprint identification security are put forward based on TrustZone to enhance the security of fingerprint identification for intelligent terminals.They provide trusted execution environment for the fingerprint identification program to ensure its safety in executing and prevent malicious code attacks.Meanwhile,the fingerprint data and fingerprint feature template are encrypted,the key is put into the secure area protected by TrustZone in order to prevent it from stealing.In addition,a secure channel for fingerprint data transmission is realized to further ensure the security of sensitive data transmission.At last,a prototype system is designed and implemented to verify the validity of the mentioned technique and method.The experimental results verify that the technique and method proposed in this paper are feasible.
