Apparatus and methods for content- and context-based biometric authentication are provided. The apparatus and methods may include using multiple biometric sensors and an authentication engine that decides which sensor(s) to use through a content- and/or context-based analysis. The apparatus and methods may include requesting authentication, analyzing the request to determine which sensor(s) is appropriate, prompting a user to use the sensor(s) and comparing the data received with data stored in a database to provide authentication.
