US 2004/0107215 A1 · Method and apparatus for identifying electronic files

Abstract

The invention provides a method and apparatus for identifying electronic files under test. According to the invention, this process of identification involves reading a master file including a master signal sequence, dividing the master signal sequence into segments, generating a reference indicator representing each master signal segment, storing the respective reference indicators as a master profile, reading a test file including a test signal sequence, dividing the test signal sequence into segments, generating respective test indicators for successive segments of the test signal sequence to form a test profile, comparing the reference indicators and the test indicators successively for respective corresponding segments of the master and the test signal sequences, determining whether the reference indicators and the test indicators match, and generating a corresponding indication.
