This is known as a perceptual hash. We have a perceptual audio hash in pHash, my open source software project that will tell you how similar two media files are to each other. It also features an indexing system to find the best matches from a sample audio clip, a la Shazam. These algorithms are not new by any means, although this patent goes a bit further than simply matching audio samples.

To take advantage of the change in your Firefox search bar on Linux, edit the ~/.mozilla/firefox/xxxxxx.default/search.json file and change all URL references to Google to "https" where xxxxxx is the random string created by Firefox. I assume it's similar for other operating systems.

While this is a step i nthe right direction, I believe only the results of your search are encrypted, not the search string itself. Perhaps Google should make the search a POST and not a GET. That should solve the problem of your search string appearing in the URL.

Their SHA1 hashing method will not be sufficient to detect most copyright infringements. Even one bit change in a file will result in a completely different SHA1 hash. I am the creator of pHash, which is well suited for this type of similarity search. The hashes do not need to be identical in order to detect duplicate or similar files, and similar files will have hashes that are "close" to one another. This is really what they should be using.
