Abstract
The present disclosure discloses a method and network device for providing anonymization of client data in a wireless local area network. Specifically, a network device adds a first client device identifier containing private personal data (e.g., a Media Access Control (MAC) address and/or an Internet Protocol (IP) address) into a large data file, and sends at least a portion of the large data file as input to a one-way hash function to generate a second client device identifier for the client device. The network device then provides to a third party client context information with the second client device identifier without providing the first client device identifier. No private personal data can be derived from the second client device identifier. Thus, the disclosed system protects wireless clients' privacy while facilitating analytics of client data by an external third party.
