  • Patent number: 11646885
    Abstract: Systems and methods for processing tokenization requests to facilitate safe storage of tokens. A tokenization request comprising sensitive data is received. A sensitive data digest is generated based on the sensitive data and a query comprising the sensitive data digest is submitted to a database. The database stores a plurality of relational elements. Each relational element being mapped to: (i) a given sensitive data digest stored in the database and (ii) a given token digest stored in the database. A token associated with the sensitive data is generated based on a response to the query received from the database.
    Type: Grant

  • Patent number: 11455422
    Abstract: Systems and methods for processing tokenization requests to facilitate safe storage of tokens. An epoch is identified as a current epoch based on a current system time of a node. A seed value is computed by the node based on a start time of the epoch and a secret. A plurality of ephemeral tokens is generated by a randomization service of the node for a set of sensitive data based on the seed value. Each ephemeral token of the plurality of ephemeral tokens has a usable life defined by the epoch. Each sensitive data instance in the set of sensitive data is associated with a particular ephemeral token of the plurality of ephemeral tokens to create a mapping structure in a main memory of the node. A tokenization service of the node is configured to process tokenization requests using the mapping structure.
