  • Systems and methods for data synchronization
    Patent number: 10983872
    Abstract: Systems and methods for data synchronization are provided. The system may include a first Hadoop service cluster, a second Hadoop service cluster and a third service cluster. The first Hadoop service cluster may store the file metadata from a client. The second Hadoop service cluster connects to the first Hadoop service cluster. The third service cluster may back up updated data block of the first Hadoop service cluster to the second Hadoop service cluster.
    Type: Grant
    Filed: October 11, 2020
    Date of Patent: April 20, 2021

  • Methods and apparatus using human electrocardiogram to protect electronic data
    Patent number: 10853516
    Abstract: In a method for protecting electronic data, a data processing system (20, 20A, 20B) uses (a) a master electrocardiogram (ECG) identifier (44) for an authorized user of the system and (b) a secret chip key (26) for the system to encrypt data in the system. Also, before allowing the encrypted data to be decrypted, the system collects an ECG reading for a current user of the system and uses (a) the collected ECG reading for the current user and (b) at least one predetermined ECG identifier (EID) vector for the authorized user to determine whether the current user is the authorized user. In response to determining that the current user is the authorized user, the system uses the master ECG identifier (44) for the authorized user and the secret chip key (26) for the system to decrypt the data.
