Sample text

When the digest of a message is encrypted using the sender's private key and is appended to the original message, the result is known as the digital signature of the message. The recipient of the digital signature can be sure that the message really came from the sender by decrypting the message using the sender's public key. And, because changing Symmetric Adaptive Customer Modeling 21 even one character in the message changes the message digest in an unpredictable way, the recipient can be sure that the message was not changed after the message digest was generated.

2 Preliminaries Our goal is to choose an optimal seller's pricing algorithm for a given loss function and an interval 0 , . . , N of possible buyer's valuations (or maximum buyer's prices). Recall that, in this paper, the maximum buyer's price reflects not the actual price, but rather an additional amount, the buyer is willing to pay over a fixed minimum seller's price. The notion of "maximizing profit" is a little tricky in this case, as it often happens in many problems associated with on-line algorithms in general and on-line learning theory in particular.

1 Introduction Electronic Commerce (EC) is getting much interest as research field, due to the development and widespread usage of the Internet and the World Wide Web. The sky-rocketing increase in number of users connected to the network makes this field central and i m p o r t a n t both from the scientifical and the commercial point of view. Many enterprises are offering services and goods through the network to an always wider audience and the challenge to the researchers is to develop and study distributed systems that are able to fulfill the promises of such "revolution".
