Abstract: Techniques are provided herein for coordinated data obfuscation. In one example, a first network device in a network obtains, from a controller in or having communication to the network, an obfuscation parameter that is further obtained by one or more second network devices in the network. Personally Identifiable Information (PII) of the first network device has a given logical relationship to PII of the one or more second network devices. Based on the obfuscation parameter, the first network device obfuscates the PII of the first network device to generate obfuscated PII of the first network device. The obfuscated PII of the first network device has the given logical relationship to obfuscated PII of the one or more second network devices. The first network device provides the obfuscated PII of the first network device to a server configured to collect the obfuscated PII of the one or more second network devices.
