Claim 0:
1. A method for obfuscating a request for transmitting to a recommender server, the method comprising:
presenting, by at least one processor, a first subset of a plurality of information items via an interface to a user, and receiving via the interface a first selection of at least one item by the user from the first subset of the plurality of items;
assembling, by the at least one processor, a first request containing the first selection and a selection of another subset of the plurality of items selected by the at least one processor, wherein each item of the first request defines one of a plurality of clusters;
transmitting the first request from a memory of the at least one processor to a recommender server; and
performing, by the at least one processor, recursive operations for assembling at least one subsequent request by the user containing at least one subsequent selection and selection noise indicating a superset of an actual selection history for the user; wherein the at least one processor generates the selection noise for each item in the subsequent selection at least in part by choosing from each cluster a selection noise item having a ranked measure proportional to a ranked measure of the at least one item selected by the user, and appending the selection noise item to the next subsequent request.
