Mobile Payment Tokenization via Intermediary Layer

The patent introduces a tokenization intermediary layer that replaces sensitive data with tokens before transmission and storage. This intermediary mechanism (tokenization service) converts actual sensitive data into token representations, which cannot be reverse-engineered even if intercepted. The tokenization process eliminates the need for traditional encryption/decryption cycles and associated audit requirements, while maintaining data security through unbreakable token mappings stored securely in token vaults.

The patent extracts the sensitive data from the storage environment entirely by replacing it with tokens at the point of capture. Instead of securing sensitive data in storage systems with complex security measures, the actual sensitive data is removed from the storage ecosystem and replaced with inert tokens. Even if unauthorized entities bypass storage security measures, they only obtain tokens that cannot be converted back to sensitive data without access to the tokenization service's secure token vaults.

The patent applies preliminary action by performing tokenization at the very first point where sensitive data is captured (e.g., at the mobile device or point-of-sale terminal) before any wireless transmission occurs. This preliminary transformation converts sensitive data into tokens upfront, so that all subsequent wireless transmissions between authorized entities involve only tokens rather than actual sensitive data. This eliminates interception vulnerability across the entire transmission chain while maintaining processing capability.
