Digital watermarking protocols are the one, which have combined fingerprinting technique with watermarking, for embedding digital signal or watermark into an original multimedia object. Buyer-seller watermarking protocol is fundamentally applied to continue the digital rights of both buyers and seller. We proposed an identity-based buyer-seller watermarking protocol that encounters various weak...

A brief survey of the economics of price dispersion, written for the New Palgrave Dictionary of Economics, 2nd Edition. Journal of Economic Literature classification numbers: C72, D43, D82, D83. Price dispersion occurs when different sellers offer different prices for the same good in a given market. Thus, it differs from price discrimination under which a single seller offers different prices ...

In the dual-channel supply chain, relationship between electronic direct selling channel and traditional is situated in an antagonistic game. The present study used master-slave game model to analyze chain structure, where manufacturer leader of game, seller follower Based on analysis theory, order analyzed state demand information sharing. decision each member constructed, optimal production p...

We study a buyer-seller problem in which the good is information and there are no property rights. The buyer is reluctant to pay for information whose value he does not know, but the seller cannot credibly reveal this value without disclosing the information itself. Information comes as divisible hard evidence. We show how the seller can appropriate a substantial fraction of the value through g...

A buyer wishes to purchase a good from a seller who chooses a sequence of prices over time. In each period, the buyer can also exercise an outside option such as moving onto another seller. We show there is a unique equilibrium in which the seller charges a constant price in every period equal to the monopoly price against their residual demand. This result contravenes the Coase conjecture.

Many time-consuming and arduous transactions have been greatly simplified and sped-up. In modern electronic financial markets, for example, high frequency trading has become a critical component and has resulted in a greatly increased volume of trade. Given the recent f...

the secure embedding scheme (see Section II), it is hard to generate a watermarked version of c which has a low correlation with k 0. An estimation attack usually yields a watermarked object that still correlates well with k 0 ; a judge will reject the accusation on such an object, as it can only originate from a malicious seller (k 0 is only available to the seller). • Finally, can attempt to ...
