    Abstract: Techniques for authenticating a biometric input are disclosed. An example of a biometric authentication system is configured to receive a biometric input, perform a first authentication process on the biometric input with an application processor, such that the first authentication process generates one or more authentication parameters, provide the one or more authentication parameters to a secure processor, perform a second authentication process on the biometric input on the secure processor, such that the second authentication process utilizes the one or more authentication parameters, and output an authentication score based on the second authentication process.

    Abstract: Techniques for providing countermeasures against physical attacks on the contents of off-chip memory are provided in which a pseudo-internal memory resistant to physical attack is used. The pseudo-internal memory is mapped to an address space such that the pseudo-internal memory appears to be on-chip memory to a processor or a system on a chip (SoC). A method for protecting sensitive data according to these techniques includes presenting, by a pseudo-internal memory module of a SoC, an address space as internal memory of the SoC, where the address space comprises memory located off-chip from the system on a chip, receiving a data write request at the pseudo-internal memory module from a component of the SoC, encrypting data associated with the data write request using the pseudo-internal memory module to generate encrypted data, and writing the encrypted data to the memory located off-chip from the SoC.

    Abstract: Methods, apparatus, and computer program products for controlling access to an electronic device based on biometric input are described. An example of such a method includes receiving a current biometric input, determining template similarity scores for the current biometric input, if at least one template similarity score satisfies a template similarity score criterion, then updating a false user counter value in a first numerical direction and performing an authentication process on the current biometric input, else, determining stored biometric input similarity scores for the current biometric input, if at least one stored biometric input similarity score satisfies a stored biometric input similarity score criterion, then maintaining the false user counter value, else, replacing a previously stored biometric input with the current biometric input, and updating the false user counter value in a second numerical direction opposite to the first numerical direction.
