  • Publication number: 20240161884
    Abstract: Systems and techniques are described herein for user identification. For instance, a technique can include receiving at least one biosignal from a sensor, the at least one biosignal indicative of a blood perfusion of a user. The technique can further include extracting at least one feature from the at least one biosignal, comparing the extracted at least one feature to at least one template feature associated with an enrolled user, determining, based on comparing the extracted at least one feature to the at least one template feature, whether the user matches the enrolled user, and outputting an indication of whether the user matches the enrolled user.

  • Patent number: 8862967
    Abstract: A method may be performed at a data storage device that includes a memory and a controller. The method includes providing user data to a variable-bit error correction coding (ECC) encoder. The ECC encoder generates a first set of parity bits. A first number of parity bits in the first set of parity bits is determined based on stored counts of read errors. The method also includes storing the user data and the first set of parity bits to a memory of the data storage device.
