Description
一般ユーザにより作成された映像・音楽コンテンツであるUGC(user-generated content)は,ネットワークのブロードバンド化にともない配布と利用がさかんに行われつつある.現在,ほとんどのUGCは無料で提供されているが,今後UGCがメディアとして健全に発展していくためにはコンテンツの作成者に対して適切な収益分配を行えるようにすることが望ましい.しかし,コンテンツの質に関して玉石混淆であるUGCを従来のコンテンツ販売方法で売買することは,購入したコンテンツの質に関して購入者に大きなリスクを負わせ,「レモン市場化」と呼ばれる現象により商品であるコンテンツの質のさらなる劣化と市場全体の衰退を招く恐れがある.本稿では,上記のUGC流通における購入者のリスクを低減させる手段として,コンテンツの逐次微小課金に着目し,ICカードを用いた安全かつ実用的な実現方式を提案するとともに,その安全性と実現性について議論する.
UGC (user-generated content), also known as CGM (consumer-generated media) or UCC (user-created content), has been rapidly diffusing among the internet users and mobile phone users along with the recent spread of wired or wireless broadband internet access. Most of them are distributed free mainly because of the lack of the adequate billing scheme; the currently deployed billing schemes for content are inadequate for UGC, of which creator and quality are much more diverce than content created by professional creators, and accordingly the users have the risk to pay too much for crude or useless content. This risk may lead the UGC market to a lemon market, where most merchandises (i.e. UGC) in the market becomes inferior in quality. This paper discusses measures to address this problem and proposes a solution introducing a smartcard-based micro-billing scheme for UGC, by which a user pays for content according to how much she or he plays it, and thus the risk of the quality of content is mitigated. This paper also shows that the proposed scheme can be implemented securely and feasibly by using current smartcards.
