A recently granted patent (Publication Number: US11973873B2) outlines a method for data matching to identify data content through a multi-tenant cloud-based system. The method involves providing a User Interface (UI) for customers to upload sensitive data and configure specific settings for data matching. Upon receiving customer-specific data, it is converted into tokens such as word, number, alphanumeric, and email tokens. The system then performs inline monitoring of user traffic, tokenization, and normalization of content obtained from monitoring. By detecting the presence of tokens in the monitored content, actions based on the customer's configuration are executed, which may include blocking outbound traffic or reporting the detection of matching tokens.

Furthermore, the method involves distributing tokens across enforcement nodes of the cloud-based system, allowing for the detection of tokens in content processed at these nodes. Each customer has unique sensitive data and configurations for data matching. In the event of updated customer data, the system determines the changes and distributes only the delta tokens across enforcement nodes. Additionally, the tokens are stored as hashes via a one-way hash function to protect sensitive data. Customers perform the one-way hash before providing tokens to the system, ensuring the security and confidentiality of their data throughout the data matching process. The method optimizes scanning of tokens, including looking back at characters for alphanumeric tokens, to enhance the efficiency and accuracy of data matching within the cloud-based system.
