1. A storage disk or storage device comprising instructions that, when executed, cause a computing device to at least:

  • generate, in a first trusted execution environment (TEE), an indicator when biometric data from a biometric capture device matches a stored biometric template;

    transmit the indicator and signed data generated in the first TEE to a second TEE, the signed data to identify the first TEE, the first TEE being independent from the second TEE, the second TEE being sealed; and

    in response to determining that the indicator is from the first TEE based on the signed data, unseal the second TEE based on the indicator to facilitate access to the second TEE.
