The present invention relates to an optical disc authentication method and apparatus. The method, wherein each disc has a plurality of ways and a plurality of sectors in each way, includes the steps of measuring the quanti ty of sectors in each of a defined quantity of ways to provide a disc fingerpri nt comprising way sector quantity values for an original disc and a target disc and authenticating the target disc. The step of authenticating the target di sc includes the steps of comparing the target disc fingerprint to the original disc fingerprint to determine a percentage of coinciding way sector quantity valu es and classifying the target disc according to whether its determined percenta ge value is above or below a pre-defined percentage threshold value, wherein a target disc having a determined percentage value of greater than or equal to the threshold value is classified as an original disc, and a target disc having a determined percentage value of less than the threshold value is classified a s an illegally copied disc.
