Abstract

See full text

A tokenization system includes a vector table and one or more token tables. The tokenization system accesses sensitive data and a vector from a vector table column, and modifies the sensitive data based on the accessed vector. The tokenization system then queries the one or more token tables using a portion of the modified data to identify a token mapped to the portion of the modified data. The portion of the modified data is replaced with the token to create tokenized data. The vector table can be updated by replacing a vector table column with an updated vector table column. The tokenization system can modify subsequent data using the updated vector column prior to tokenization.
