Methods and systems for auto-completion of anonymized strings

Abstract:

A proxy server receives, from a client device, a partial query entered at the client device. The partial query includes a first substring of a full query. The first substring is replaced with a first anonymized string that is correlated with the first substring. The first anonymized string is forwarded to a web server. A second anonymized string stored by the web server in association with the first anonymized string is received from the web server in response to the first anonymized string. The second anonymized string is translated into a first de-anonymized string that is correlated with the second anonymized string. A first autocomplete suggestion including the first de-anonymized string is sent to the client device.
