Readium LCP DRM - Page 2

Yeah, I agree. Adobe has turned over management to Harman, which is not the same thing as phasing out ADE. This indicates that Adobe doesn't want to manage the software or backend anymore, but ADE is still so widely used that somebody has to maintain it.

The only probable issue I see is those who have been downloading older versions such as earlier versions of Adobe's ADE which are likely to disappear during the changeover.

Here's where to download ADE 2.0.1 and ADE 3.0.

It looks like Harman Connected Services was immediately sold to Wipro in December 2025.

Well, ADE and Adobe ADEPT DRM have been neglected for a very long time.

And it would be best for users if it remained so. We don't want yet another hard-to-get-rid-of DRM infestation.

We can be fairly sure that there will be some pretty bad code written that could be exploitable if they do decide to put in some changes.

BOOK☆WALKER Global, the global division of the Japanese eBook store BOOK☆WALKER (KADOKAWA Group), will migrate from the Japan and Global stores’ common proprietary DRM to Readium LCP in February.

【田中委員】　出版業界側から付け加えさせていただきますと、LCPに関しては、我々はDRMだとは思っていません。認証はされていますけれども、著作権を保護されているという認識を持っていないので、この場で付け加えさせていただきます。
　以上です。

Quote:

【田中委員】　DRMのところを追加すると、電子書店で買っていただいた段階で電子書店のビューアとコンテンツがDRMで保護されているという状態は、現状、日本でそういうのが広がっておりますので、ヨーロッパ、フランスとかで使われているReadium LCP、どのビューアでも使えるという形のものが導入されるということの可能性は低いだろうと考えております。国内の問題としてはそういうふうに考えております。

Quote:

【Committee Member Tanaka】 On behalf of the publishing industry, I would like to add that we do not consider LCP to be DRM. While it does involve authentication, we do not believe it protects copyrights, so I wanted to make that clear here.
That is all.

Quote:

【Committee Member Tanaka】 To elaborate on the DRM point, the current situation that is widespread in Japan is that when you purchase from an e-bookstore, the e-bookstore's viewer and the content are protected by DRM. Therefore, we believe it is unlikely that a system like Readium LCP, which is used in Europe and France and allows use on any viewer, will be introduced. That is our view on the domestic situation.

The reaction from Japanese publishing stakeholders regarding Readium LCP was extremely negative, and they said that Readium LCP is not DRM.

Sirtel · 01-27-2026, 05:46 AM

What did they mean, "allows use on any viewer?" It doesn't.

JSWolf · 01-27-2026, 06:27 AM

LCP is 100% DRM. It does not allow you to view your eBooks with any program that can display ePub.

BOOK☆WALKER Global needs to get thhere heads out of there backside. What they are saying is a lie.

Cactus Chef · 01-27-2026, 10:22 AM

Well there you have it. It's not "DRM"--it's "Enhanced authentication".

That's 100% BS. It's DRM plain and simple.

I'm aware. I was making an ancient "enhanced interrogation" joke. Maybe we're so far from that point that it's no longer funny...

No, the pendulum has swung all the way back, what with the new definitions of "self defense" and all.
