An Efficient Fair Electronic Payment System Based upon Non-Signature Authenticated Encryption Scheme
[[abstract]]In this paper, we first propose a non-signature authenticated encryption
scheme, which accomplishes the message authentication, confidentiality, and integrity
for communications on an open channel. Compared with the related works, the proposed
scheme does not require constructing the digital signature so that the computation costs
can be reduced. Based upon the non-signature authenticated encryption scheme, we fur-
ther propose a fair electronic payment system such that the payment information can
be securely transmitted on Internet. Moreover, the proposed electronic payment system
can solve the synchronization problem between the payer and the merchant. Therefore,
the transaction fairness of the payer and the merchant can be efficiently accomplished
in off-line environments. According to the above-mentioned advantages, the proposed
electronic payment system provides an efficient and practical payment tool for electronic
transactions
Fairs for e-commerce: the benefits of aggregating buyers and sellers
In recent years, many new and interesting models of successful online
business have been developed. Many of these are based on the competition
between users, such as online auctions, where the product price is not fixed
and tends to rise. Other models, including group-buying, are based on
cooperation between users, characterized by a dynamic price of the product that
tends to go down. There is not yet a business model in which both sellers and
buyers are grouped in order to negotiate on a specific product or service. The
present study investigates a new extension of the group-buying model, called
fair, which allows aggregation of demand and supply for price optimization, in
a cooperative manner. Additionally, our system also aggregates products and
destinations for shipping optimization. We introduced the following new
relevant input parameters in order to implement a double-side aggregation: (a)
price-quantity curves provided by the seller; (b) waiting time, that is, the
longer buyers wait, the greater discount they get; (c) payment time, which
determines if the buyer pays before, during or after receiving the product; (d)
the distance between the place where products are available and the place of
shipment, provided in advance by the buyer or dynamically suggested by the
system. To analyze the proposed model we implemented a system prototype and a
simulator that allow to study effects of changing some input parameters. We
analyzed the dynamic price model in fairs having one single seller and a
combination of selected sellers. The results are very encouraging and motivate
further investigation on this topic
Lex Informatica: The Formulation of Information Policy Rules through Technology
Historically, law and government regulation have established default rules for information policy, including constitutional rules on freedom of expression and statutory rights of ownership of information. This Article will show that for network environments and the Information Society, however, law and government regulation are not the only source of rule-making. Technological capabilities and system design choices impose rules on participants. The creation and implementation of information policy are embedded in network designs and standards as well as in system configurations. Even user preferences and technical choices create overarching, local default rules. This Article argues, in essence, that the set of rules for information flows imposed by technology and communication networks form a “Lex Informatica” that policymakers must understand, consciously recognize, and encourage
