In 2004, Working Group on Electronic Commerce of the United Nations Commission on International Trade Law (UNCITRAL) had made a draft on e-commerce convention. This draft was intended to facilitate e-commerce by removing current barriers. According to the Working Group Chairman, Jeffrey Chan of Singapore, This work will benefit world trade, as it will enable and encourage the greater use of e-commerce. He further said that nowadays, more transactions are being conducted through electronic means. However, there was problem with regards to legal rules of contracts. This is because in international business, different countries have different legal rules for contracts and it creates uncertainty when the same transaction is conducted across international borders.
This is encryption for the internet that uses algorithm for authorised users. This uses public key pairs that decrypts from public and the private key pairs to encrypt and public key to decrypt. Some of the benefits for SSL are that it provides you encrypted data and provides authentication that protects against phishing, I recommend having SSL on certain part of the website e.g. the payment section of the DLT's site as it will gain customer trust more than without SSL as well as the reason stated above. Some of the drawbacks SSL are the costs as you will need a trusted infrastructure and the providers that a well-know and trusted can be very expensive. Another drawback can be the performance site as it requires a lot more CPU power from the server as it's encrypting and decrypting data.
To maximize success and achieve scale, automated bid management systems can be deployed. These systems can be used directly by the advertiser, though they are more commonly used by advertising agencies that offer PPC bid management as a service. These tools generally allow for bid management at scale, with thousands or even millions of PPC bids controlled by a highly automated system. The system generally sets each bid based on the goal that has been set for it, such as maximize profit, maximize traffic, get the very targeted customer at break even, and so forth. The system is usually tied into the advertiser's website and fed the results of each click, which then allows it to set bids. The effectiveness of these systems is directly related to the quality and quantity of the performance data that they have to work with — low-traffic ads can lead to a scarcity of data problem that renders many bid management tools useless at worst, or inefficient at best.http://www.reviewengin.com/profit-engine-review/
