Is Amazon's New Silk 'Cloud' Browser A Huge Copyright Infringement Lawsuit Waiting To Happen?

from the caching dept

There’s been plenty of fanfare over Amazon’s new Android-based e-reader, the Kindle Fire, with one interesting feature being the new Silk browser, which is differentiated by the fact that it’s built on top of Amazon’s cloud web services storage, allowing it to effectively cache and optimize content on its own servers. But this raises a big question. As Stephan Kinsella points out, technically, this may be copyright infringment. First up, here’s Amazon’s video explanation of the browser:

Based on the info in that video, Kinsella explains the legal concerns:

One smart thing Silk does to speed up web browsing as seen by the user of the Kindle Fire by ?pre-loading? content into Amazon?s ?cache? in its own ?Amazon computer cloud? (i.e. Amazon?s servers)?and to optimize them for the Kindle Fire (e.g., a 3MB image is scaled down maybe to 50k because that would look the same on the Kindle Fire as a 3MB image, but could be transmitted more quickly). But to do this Amazon?s servers have to store copies of files obtained from other websites, including images (as explicitly stated at 3:07 to 3:26) and other files which, of course, are covered by copyright. At 3:54, it?s explained that if Amazon?s computing cloud sees you looking at the New York Times home page, and it predicts, based on other user statistics, that you are somewhat likely to next click on some NY Times subpage link, then the Amazon servers will go ahead and download that next link, and cache it, in case you do click on it next, so that it can serve it up more quickly. Now this makes sense technically, but what it really means is Amazon?s servers are making copies of other people?s copyright-protected content: images, files, NYTimes web pages, and serving them up to Kindle Fire users as if the Amazon computer cloud servers are the host of those images. It is a bit like if Amazon ran a site called, and had its servers constantly copying content from and duplicating it on, and serving up the content on (which was copied from to browsers.

Of course, as he notes (and as the people in the video note), this makes tremendous technological sense. It makes for a much better experience. But copyright can and often is used to stop innovations that make tremendous technological sense, because they can upset legacy business models. Of course, one could argue that what Amazon is doing here is no different than what Google does with it’s cache — but that might not stop a potential legal fight, unfortunately.

Re: Re: What?!?!

Caching = copying from a copyright perspective.

Now, copying is not always infringement, but it might be enough grounds for some overzealous plaintiff to bring a suit.

I suspect any suit would ultimately find most of what Amazon is doing here to be noninfringing (a la the Perfect 10 lawsuits regarding what Google does), but that doesn’t mean the lawsuits won’t come.

Re: Re: What?!?!

So Caching is only copyright infringement when the dinosaurs want it to be copyright infringement.

So imagine this: what if Amazon’s system caches something that is in fact infringing copyright? If someone out of easy reach of jurisdiction has a web page with copyright infringing content, and Amazon caches it in the US, who is going to get sued?

I suspect Mike is right. This is a copyright lawsuit waiting to happen. Why? Because it is the default first action of pro-copyright people. Sue first. Don’t bother asking questions or ever thinking about anything later.

Re: Re: Re: What?!?!

I’m torn on the money question. Amazon has a lot more money so winning a judgement against them means you’ll actually get paid (because let’s be honest, if the RIAA does get what it wants from Jammie Thomas, she’ll never be able to pay them). At the same time, Amazon has a lot more money and is going to be much more willing to fight this than some poor schmoe.

What worries me...

Is how does it deal with encrypted content?

They’re using a custom closed-source browser – all of the traffic is flowing through their servers, so they can “optimize” it.

What about encrypted sessions? Is it safe to visit my bank’s website with this? How do they guarantee to me that they won’t be compromising my accounts?

Re: Re: Re:

Too bad nobody figured it out. This is the perfect example of the “enabler” middleman which, in the end, is just a middleman. If they aren’t selling you stuff of “gatekeeping”, they are selling your information, preferences, and whatnot to third parties (in aggregate, of course!).

Middlemen. You can call them something else, but they still end up between you and what you want (and have the ability to control or modify your access to it).

One browser or two?

It could be argued that Amazon’s Silk browser is just a unusual multiprocess model that runs the render half of the browser on a tablet and the network and caching half on a cloud server.

All the controversial features described are available in current desktop browsers. Amazon can also hide behind the exceptions written into copyright law for transition and service providers.

Re: One browser or two?

You are right from a technology point of view.

But technical qualifications are not enough.

You are insufficiently brain damaged to clearly see this from a pro-copyright point of view. If someone out of easy reach of US jurisdiction has a web page with copyright infringing content, and Amazon caches it on servers in the US, guess who is going to get sued?

Michael Long (profile) says:

Near as I can tell, plenty of ISPs do pretty the same thing: cache frequently requested information in servers close to the user, minimizing traffic on the backbone and reducing lag.

AOL, as I recall, did EXACTLY the same thing so that its users had a better experience.

And many dialup providers link Earthlink had software that would compress responses in order to provide a “faster” service.

In fact, I’d be more worried about patent issues in the later regard that copyright problems…

Questions I have about silk

1) Will Amazon perform Protect-IP style dns blocking of silk requests without court orders? (Their eagerness to help Senator Lieberman shut down wikileaks makes me wonder)

2) Can silk be used to bypass geographic restrictions (e.g. can Europeans obtain US-only content with silk, or vice-versa depending on where the amazon cloud servers are?)

3) Will using silk make it more difficult to track down copyright infringers (Silk’s Terms of Service indicate that they will “generally”[?] only store IP/MAC addresses for 30 days)?

Opera Mini does the ‘adjusting the content to fit the device’ thing too. You’d think that Opera would’ve been sued for this if it was problematic in any way. Of course, Opera is a lot poorer than Amazon, so they’re a less tempting target for a troll seeking to beat the money out of them with a lawyer-club.

(If Opera _has_ been sued for this, no doubt some knowledgeable person will link to it for us.)

Does Silk break HTTPS????

How does Silk work with HTTPS encrypted sessions? If Amazon is pre-rendering everything in the cloud then it will have to cheat and un-encrypt the client side of HTTPS sessions on their servers then ship it wirelessly to your tablet. Or they won’t be able to pre-render *anything* in an HTTPS session.

Pre-rendering HTTPS sessions in the cloud would be a massive security problem, privacy issue (HTTPS protects your privacy as well as providing secure financial transactions) and is a potential defacto fraud since HTTPS is supposed to be secure between the secure webserver (eg. your bank) and your web client (your browser on your computer) to insure that the information is secure the whole way along. If amazon pre-renders HTTPS then it would essentially be doing a huge equivalent of a man in the middle attack.

If google wants to be in business 5 years from now, they better do the same thing with chrome. Being able to track and apply machine learning using the browsing habits of a huge number of people, the few snippets of javascript google and tracking cookies depends on of adsense and compiling search results just won’t be enough anymore.

Being tech dirt I would think that we would be talking about the privacy concerns not weather or not it will somehow cause an infringement lawsuit.

Besides all that I love the idea. It solves the problem I’ve been thinking about of how we want everything to sparkle and depend more and more on JS and jQuery to build UI’s. How do we do this without bogging down the client device with code to execute and scripts to download.

I would take this a step further and treat your browser just like a remote desktop session where your just sending mouse and keyboard input to the cloud and getting back and image of the response.

Let me guess you are short on Amazon 😉 … Every single search engine does the same thing. To start this a legal fight and win, will force people to look at copyright, lets hope that the legacy industries win this if it becomes a legal suit. Imagine the outcry if google, bing or any other “legal” search engine were to become illegal.

As someone who’s bandwidth-challenged and not as tech-savvy as many here, does this process used by Amazon shave kb off your downloads? When you’re living with a strangulating cap — as many of we ruralites are — this could make a huge difference. Speed is nice but when you’re overcharged by the byte, every little bit helps.

Ok… and this is something that’s been going on with the Opera browser’s “Turbo” feature, and Opera Mini, Skyfire for how long? I seriously see this as a non-issue. Anyone remember the Accelerated dialup? Congrats on rehashing this shit over and over, and claiming “is this copyright infringement”. If anything there’s prior applications that already do this, and it shouldn’t be an issue at all whatsoever.

Re: Re:

“this is something that’s been going on with the Opera browser’s “Turbo” feature, and Opera Mini, Skyfire for how long”

Those companies don’t have deep pockets. As with the lawsuits against Google (did Perfect 10 ever stop suing them about their caches?), having prior art is hardly a stopping point.

“claiming “is this copyright infringement””

Re-read the headline. It’s not asking that. It’s asking “is this a copyright infringement lawsuit”. Having actual infringement has never been a prerequisite for these people to sue.

“it shouldn’t be an issue at all whatsoever”

That doesn’t mean they won’t sue.

When I’m viewing my shopping cart web page on Amazon, I wonder which link Silk will predict I’m going to press next and therefore pre-cache with a GET request: “Buy Now” or “Cancel Order”?

Or when I’m viewing my messages on Gmail: “Archive”, “Delete”, etc.? Or “Send Flirt” from

It seems like some links are a bit dangerous to pre-cache. How does Silk know which links are safe to traverse, and which aren’t?

Anonymous Coward says:

I can’t wait to hear the uproar when, a few years from now, Amazon quietly drops support for this program and leaves a bunch of people with no net access, because the “middleman” no longer wants to do the work for free.

It also brings up the most important point: If amazon is doing all of this “for free”, you have to wonder what value they are extracting. I can’t help but think there is no free lunch here, and users and making themselves beholden to another gatekeeper (who is keeping tabs on their activities and maybe inserting ads into your web pages).

This *IS* covered by the law - DMCA 512A

The DMCA provides immunity to caching servers. See 512 B (System Caching) which reads in part:

A service provider shall not be liable for monetary relief, or, except as provided in subsection (j), for injunctive or other equitable relief, for infringement of copyright by reason of the intermediate and temporary storage of material on a system or network controlled or operated by or for the service provider in a case in which
