Classification: CPC G  H | IPC G

Claim 0:
1. A method comprising:
obtaining a sequence of location events of a user over time;
analyzing the sequence of location events of the user to determine a Point Of Interest (POI) of the user;
determining that the POI is a Personally Identifiable Information (PII)-revealing POI;
obfuscating the POI, whereby generating a pseudolocation identifier of the POI, wherein the pseudolocation identifier is indicative of a semantic meaning of the POI to the user without revealing a geographic location of the POI;
generating an anonymized sequence of location events of the user based on the sequence of location events, wherein the anonymized sequence of location events comprises the pseudolocation identifier to represent location events associated with the POI, wherein the anonymized sequence of location events is absent of the geographic location of the POI;
outputting the anonymized sequence of location events of the user to a third party, whereby enabling the third party to analyze behavior of the user without divulging identity of the user;
analyzing the sequence of location events of the user to determine a second POI of the user;
determining that the second POI is a PII-revealing POI;
obfuscating the second POI, whereby generating a second pseudolocation identifier of the second POI, wherein the second pseudolocation identifier is indicative of a semantic meaning of the second POI to the user without revealing a geographic location of the second POI, wherein the second pseudolocation identifier is different from the pseudolocation identifier; and
wherein the anonymized sequence of location events comprises the pseudolocation identifier to represent location events associated with the POI and the second pseudolocation identifier to represent location events associated with the second POI, wherein the anonymized sequence of location events is absent of the geographic location of the POI and the second POI.
