Derivatives also create a daisy-chain risk that is akin to the risk run by insurers or reinsurers that lay off much of their business with others. In both cases, huge receivables from many counterparties tend to build up over time.(At Gen Re Securities, we still have $6.5 billion of receivables, though we've been in a liquidation mode for nearly a year.) A participant may see himself as prudent, believing his large credit exposures to be diversified and therefore not dangerous. Under certain circumstances, though, an exogenous event that causes the receivable from Company A to go bad will also affect those from Companies B through Z. History teaches us that a crisis often causes problems to correlate in a manner undreamed of in more tranquil times.

衍生性金融商品交易也有可能造成骨牌效应的风险，这是因为许多保险业及再保业者习惯将风险分散给其它保险公司，在这类的情况下，钜额的应收款项将随着交易对象的日趋复杂而持续累积，(以通用再保证券来说，虽然已经经过将近一年的清算期，目前仍有高达65亿美元的应收款项流通在外)，交易的一方或许对于自己相当有信心，认为其钜额的信用风险已经经过适度的分散，因此不会发生任何危险，只有等到某种特殊状况下，一个外部事件导致 A 公司的应收帐款发生问题，从而影响 B 公司，乃至于一路到 Z 公司，历史教训告诉我们危机的发生往往是我们在太平盛世时所梦想不到一连串问题串连所导致的。

The need to meet this demand can then throw the company into a liquidity crisis that may, in some cases, trigger still more downgrades. It all becomes a spiral that can lead to a corporate meltdown.

In this paper, we have proposed a flexible encryption blocks selection buyer-seller watermarking protocol integrated the RSA asymmetric encryption system and homomorphism mechanism to protect the ownership of digital contents and fit real life. And consider the secondhand transaction in the real life. We also propose a buyer-reseller watermarking protocol based on the flexible encrypt blocks selection buyer-seller watermarking protocol to offer a solution of secondhand transaction. In our scheme, it's more light data transport requirement than other schemes. All roles in protocol will benefit by their participation. Our scheme can overcome various of the known attacks and security problems in the buyer-seller watermark protocol, such as buyer's right problem, unbinding problem, piracy tracing problem, conspiracy problem, buyer's participation in the dispute resolution problem, man-in-the-middle attack problem and anonymous problem. Furthermore, the seller and arbiter can verify the buyer's watermark without decrypting it in our scheme.
