Tokenization in distributed payment environments

A system for processing payment information, comprising:

• a payment terminal, configured to:
• receive payment information associated with a transaction;
• receive a first set of tokenization parameters from a central security system;
• tokenize the payment information based on the first set of tokenization parameters to form first tokenized payment information;
• and
• output the first tokenized payment information;
• and
• a central payment system communicatively coupled to a payment network associated with the transaction, and configured to:
• receive the first set of tokenization parameters and a second set of tokenization parameters from the central security system;
• detokenize the first tokenized payment information based on the first set of tokenization parameters;
• tokenize the detokenized payment information based on the second set of tokenization parameters to form second tokenized payment information;
• and
• output the second tokenized payment information to the payment network.

A method for processing payment information, comprising:

• receiving, at a central payment system, first tokenized payment information from a payment terminal, the payment terminal configured to:
• receive payment information;
• access a first set of token tables;
• tokenize the payment information using the first set of token tables;
• transmit the first set of token tables to a central security system;
• and
• output the tokenized payment information;
• receiving, at the central payment system, the first set of token tables from the central security system;
• detokenizing, by the central payment system, the first tokenized payment information using the first set of token tables;
• accessing, by the central payment system, a second set of token tables;
• tokenizing, by the central payment system, the detokenized payment information with the second set of tables to form second tokenized payment information;
• and
• outputting, by the central payment system, the second tokenized payment information.

A central payment system for processing payment information, configured to:

• tokenize the payment information using the first set of token tables;
• transmit the first set of token tables to a central security system;
• and
• output the tokenized payment information;
• receive the first set of token tables from the central security system;
• detokenize the first tokenized payment information using the first set of token tables;
• access a second set of token tables;
• tokenize the detokenized payment information with the second set of tables to form second tokenized payment information;
• and
• output the second tokenized payment information.
