Anonymization Tier

CIMM DEFINITION:  In the process of collecting, decoding, aggregating, processing and reporting STB measurements, data may pass through multiple processing points, each of which may enforce a different level of anonymity and network access. For example, within a cable back-end a mapping between STB MAC address and subscriber information must be available for billing purposes, but network access at this level is severely restricted. This represents a low-level tier of anonymization. A processing point in a higher anonymization tier may have wider network access, but MAC address may be replaced by a unique but anonymous identifier, while billing information may be replaced by ZIP+4 or the like, providing greater anonymity.
