Security system utilizing vaultless tokenization and encryption

Abstract:

The present invention includes securing data using vaultless tokenization and encryption. The present invention uses static random token tables in conjunction with encryption methods in order to tokenize sensitive data for the purposes of secure transfer and storage. The present invention is configured to identify data for secure storage, split the data into two or more data segments, access one or more static random token tables containing random tokens, retrieve two or more random tokens from the one or more static random tables for each of the two or more data segments, combine the two or more random tokens into a tokenized sequence, and return the tokenized sequence. Moreover, additional encryption may occur before or after the data is split and/or before or after combining the random tokens into a tokenized sequence.
