Abstract
A two-stage anonymization process is applied to monitored network traffic in which unique user identifiers, such as the MSISDN (Mobile Station International Subscriber Directory Number), are extracted from the traffic and anonymized to generate an ASI (anonymized subscriber identifier). A strictly random RSI (random subscriber identifier) is generated and used to replace the ASI. The RSI is generated upon a first occurrence of an ASI and stored in a lookup table for utilization upon subsequent ASI occurrences. Use of the strictly random RSI enables various studies and analysis of user behavior to be performed at a heightened level of privacy protection as compared with conventional anonymization schemes that do not utilize strictly random identifiers.
