  • fingerprint sensors have been successfully integrated in such electronic devices, for example, thanks to their small form factor, high performance and user acceptance.
  • capacitive sensing is most commonly used, in particular in applications where size and power consumption are important.
  • Biometric systems rely on a computing environment which performs the processing of acquired images or other types of data indicative of a biometric feature of the user. Although spoofs are one concern for secure authentication using biometric systems, another concern is that the biometric authentication process itself may be subject to various attacks, such as for example physical tampering, compromising the security and integrity of the biometric system.
  • Devices that employ biometric systems for authentication of a user typically include architectural defenses to increase the difficulty of compromising the logical and physical security of the biometric authentication system.
