`(57) Abstract: A method comprising receiving a plurality of signa-
`tures representing one or more proprietary files from a vendor gener-
`ated Without disclosure of the proprietary files, each signature corre—
`sponding to a segment of a proprietary file. The method further com-
`prising and validating each of the plurality of the signatures, to ensure
`that the signatures are the proprietary code of the vendor. The method
`further comprises adding the plurality ofthe signatures to a global data-
`base, the global database used to compare the proprietary data of the
`vendor to other technology data and taking various action based on the
`results of the comparison.
