B-CASカード書き換え、有料放送見放題になる件について

やり方を知りたい人は、他をあたってください。
ちなみに、B-CASカード不正改造問題に関する当社見解によると、改善行為自体が、
B-CASカード使用許諾契約約款」に違反し損害賠償請求の対象になります。
だそうですよ。というわけで、実際にやるのは、お勧めしませんよっと。

B-CASカードを書き換えることで、有料放送が見放題になる方法が公開されてしまっている。
詳しい経緯は、まるも製作所辺りが詳しい。
要は、発行されている大半のB-CASカードのバックドアが公開されて、中身を書き換えられるようになったことで、有料放送を金払わず見放題ってわけだ。

たしかに、BLACKCASなどとして一部では販売されていたし、ケーブルテレビが見放題になるチューナーなんかも販売されていた。

今回の問題は、誰でも簡単にできてしまうということ。
必要なのは
・対応しているB-CASカード
・書き換えに使うスマートカードリーダー
・書き換えソフト
だけ。

これはいかんね。
B-CASカードを作っているのは大きく2社(T型とM型)なんだけど、一方はカードによって制限があるものの、一方は全カードできてしまう(それぞれ使うソフトが違う)。

Friioの黒をスマートカードリーダーとして使うとT型は(対応カードにも関わらず)エラーが出て不可だが、M型はできてしまう様子。
公開されている手順をちゃんと読みながらやれば、そこそこパソコンが使える人なら誰でもできてしまうと思う。

あー、こりゃいかんね。

挙句派生ソフトも出ている。
Friioなどのパソコンを使ったTS抜きができるチューナーなどでは、もはやB-CASカードが不要になっていた。ネットを通じてIDをやりとりしていたのだが、今やネットが無くてもOK、挙句に書き換えたB-CAS同様有料放送が無料で見られてしまうものまである。
こちらも試してみたところ、たしかに見られてしまうようだ。

CDのコピーなんて今や当たり前(ただし、SCMSって世代コピー制限がないわけでもないけど、パソコンでリップできちゃうよね)。
DVDやブルーレイディスクのコピーだって、できてしまう。
デジタル放送にしても、パソコンを使えば楽にTS抜きができる状況だ。

もちろく良くないことであるけれど、まだ自分でソフトを買っていて、自分だけで楽しんでいれば……という気がしないわけでもない。
もちろん、CDやDVDのコピーやTS抜きだって、結果としてまったく金を払わず見たり聞いたりしている人がいるのは問題だと思う。

しかしだ、有料放送が見放題というのは、良くない。言い訳がない、窃盗みたいなもんだ。

もちろん、やっていいことではない。
ただ、その一方で誰が悪いのかと問われれば、そんなシステムと言わざるをえない。タダで見られる、しかも簡単な手順となれば、やるヤツがいっぱいでてくるのは当たり前。それを法律違反だから……というのは難しい。
今回の場合、特に気軽にできてしまうし。

バックドアが解明されちゃうのも仕方がない、カギがある程度の部分まで漏れるのも仕方がない。
しかし、それでも簡単にブロックできる仕組みになっていなければいけなかったのだ。
B-CASの番号によって、使用不可にするという手もあるのだけど、それも回避の方法が示されてしまっている。

現実的には、既存の発行済みのB-CASカードを全部交換するしか手がない。
そして、新規のB-CASカードは使用期限を短くするなどの工夫が必要だろう。

有料放送だけ見られなくできるのであれば、とりあえず
・今の有料放送契約者には新規発行
・有料放送は既存カードに対して使用不可に

という手も使えるか。ただし、その場合、既存のB-CASカードを使っている人は、そのままでは有料放送が見られないという問題が出てくる。有料放送を見たい人は、改めて交換という作業が必要になってしまう。
有料放送をしている放送局からすれば、契約させるハードルが上がることになるので機会損失が生じることになるが、これはB-CASの不手際だからその損害をB-CAS社に請求するしかないかな……。

この際、無料放送はB-CAS無しのコピーフリーに。有料放送希望者はB-CASを申込みというのが自然な流れかもしれん。

I think everything wrote was actually very logical. But, think about this, suppose you were to create a killer headline? I mean, I don't wish to tell you how to run your website, but suppose you added a title that makes people want more? I mean B-CASカード書き換え、有料放送見放題になる件について: 鈴本薫平のCCCLXV is kinda boring. You might peek at Yahoo's front page and note how they write news titles to grab people interested. You might add a video or a picture or two to get people interested about everything've got to say. In my opinion, it could make your posts a little livelier.
