DISTRIBUTED CONTENT IDENTIFICATION SYSTEM

摘要

A file content classification system includes a digital ID generator and an ID appearance database coupled to receive IDs from the ID generator. The system further includes a characteristic comparison routine identifying the file as having a characteristic based on ID appearance in the appearance database. In a further aspect, a method for identifying a characteristic of a data file comprises the steps of: generating a digital identifier for the data file and forwarding the identifier to a processing system; determining whether the forwarded identifier matches a characteristic of other identifiers; and processing the data file based on said step of determination.
