Managing latency and power in a heterogeneous distributed biometric authentication hardware

A system for authenticating a biometric input, comprising:

• a first processor executing a first processing stream configured to generate image information based on the biometric input;
• a second processor executing a second processing stream configured to:
• receive the image information from the first processing stream;
• generate authentication information based on the image information;
• generate a first set of match parameters based on the image information;
• a third processor executing a third processing stream configured to:
• receive the image information from the second processing stream;
• receive the authentication information and the first set of match parameters from the second processing stream;
• generate a second set of match parameters based on the image information and the authentication information;
• and
• authenticate the biometric input based on the first set of match parameters and the second set of match parameters, wherein at least a portion of the second processing stream and the third processing stream occur concurrently.

A computer program product, comprising:

• a first non-transitory computer-readable storage medium comprising code for a first processing stream including code for generating image information based on a biometric input;
• a second non-transitory computer-readable storage medium comprising code for a second processing stream including:
• code for receiving the image information from the first processing stream;
• code for generating authentication information based on the image information;
• code for generating a first set of match parameters based on the image information;
• a third non-transitory computer-readable storage medium comprising code for a third processing stream including:
• code for receiving the image information from the second processing stream;
• code for receiving the authentication information and the first set of match parameters from the second processing stream;
• code for generating a second set of match parameters based on the image information and the authentication information;
• and
• code for authenticating the biometric input based on the first set of match parameters and the second set of match parameters, wherein at least a portion of the second processing stream and the third processing stream occur concurrently.

An apparatus for authenticating a biometric input, comprising:

• means for receiving image capture information from a first processing stream;
• means for generating a first image and authentication information with a second processing stream based at least part on the image capture information received from the first processing stream;
• means for providing the first image and the authentication information to a third processing stream;
• means for concurrently performing a first pattern matching process based on the first image with the second processing stream and a second pattern feature extraction process with the third processing stream, wherein the second pattern feature extraction process is based on the first image and the authentication information provided by the second processing stream;
• means for providing a first set of match parameters based on the first pattern matching process to the third processing stream;
• means for determining a second set of match parameters based on a second pattern matching process performed with the third processing stream;
• means for generating a match score based on the first set of match parameters and the second set of match parameters;
• and
• means for authenticating the biometric input based on the match score.
