Abstract
A method is described. The method includes streaming subject data from a subject repository. The method also includes storing a subject length of the subject data. The method further includes executing a hash function on the subject data to produce a subject hash value. The method additionally includes executing the hash function on content data from a content stream based on the subject length to produce a content hash value. The method also includes detecting whether the content data matches the subject data based on the subject hash value and the content hash value. The method further includes reporting a match detection in response to detecting that the content data matches the subject data.
