I have told this earlier too, big brands on the web are not just because of the single script they use but also unique thinking behind the smallest thing they choose. Here is YouTube’s step for protecting big media companies from pirated uploads.
Recently I wrote a post about Facebook’s relation tracking algorithm. The algorithm is quite complex which detects best buddies of you from thousands of friends. Same way one unique thing I noticed in YouTube’s script is piracy protection.
Users are supposed to upload pirated videos or songs to get subscriptions to their channels. If everyone does this music companies will be in big loss as well as YouTube itself will face many legal/ Digital Millennium Copyright Act notices for number of users.
To reduce such problems, after upload of a video YouTube scans it and checks for digital signature or patterns. If the music or video is found from big industry names YouTube will ban the video for copyrighted countries. Also it warns the uploader about it.
One normal video upload site would just remove the video after complaint is received. But scanning the video, matching signature from database and restricting the video at same moment, that’s a step which is only possible from a big brand !
Below is sample screenshot of YouTube’s email upon copyright infringement upload.
