MANAGING PROGRESSIVE STATISTICAL IDS

摘要

A method, system, and computer program product for managing user identification codes in an internet advertising environment. One aspect implements a system including a database engine to store a plurality of signals comprising characteristics and/or values received from a user device. A user ID generator calculates collision statistics and/or fragmentation statistics to form a first mapping function that is in turn used to generate a plurality of identification codes based at least in part a first set of selected signals. A calibration module produces measurements determined from collision quantities and/or fragmentation quantities using the first mapping function, wherein the measurements are determined by comparing the plurality of identification codes to entries in a known ID database. A sequencing module generates updated sequences of mapping functions.

1. A method for managing a progression of user identification code generators, comprising:
identifying a set of mapping functions that form a sequence of mapping functions, the sequence having a first mapping function and a last mapping function, wherein at least the first mapping function and the last mapping function generates user identification codes, wherein the first mapping function generates user identification codes based on a first set of characteristics and the last mapping function generates user identification codes based on a second set of characteristics; constructing an incremental mapping function, the incremental mapping function using at least some inputs different from the mapping function of the last mapping function, wherein constructing the incremental mapping function uses one or more new characteristics that were added to a target set of characteristics after generation of the first mapping function and after generation of the last mapping function, and wherein the first mapping function and the last mapping function do not use the one or more new characteristics, and wherein the incremental mapping function uses the one or more new characteristics; and establishing the incremental mapping function as a new last mapping function to generate a new sequence of mapping functions.
