E-Commerce 3

E-Commerce
Ecommerce, or Electronic Commerce is a rapidly evolving technology in the world of the internet's. Penggunaann E-Com system, it is usually abbreviated Ecommerce, may actually benefit many parties, both the consumer and the producer and the seller (retailer). In Indonesia, Ecom system is less popular, because many internet users who still doubt the security of these systems, and their lack of knowledge about what the actual E-Com.For the consumer, using the E-Com can make shopping a short time. No more to linger around the shopping center to find the desired item. In addition, the price of goods sold through E-Com is usually cheaper than the price in a store, because the distribution channel from producers of goods to the seller's shorter than the conventional stores.Online shopping provides many conveniences and advantages when compared with the conventional way of shopping. In addition to being faster, the internet has provided almost all kinds of goods are usually sold in full. In addition, most information about merchandise available in full, so even though we do not buy it on-line, we can get a lot of important information needed to select a product to be purchasedMechanism of E-CommerceBuyers who want to choose one to buy groceries can use the 'shopping cart' to store data about the items that have been selected and will be paid. The concept of 'shopping cart' mimics the shopping cart that is usually used by people to shop in supermarkets. 'Shopping cart' is usually a form in the web, and made with a combination of CGI, databases, and HTML. Items that have been incorporated into the shopping cart can still be canceled, if the purchaser intends to cancel the purchase of the goods.If the buyer wants to pay for goods that have been selected, he should fill in the form of the transaction. Usually this form to ask the identity of the buyer as well as credit card numbers. Because this information could be misused if it falls into the wrong hands, then the e-commerce service provider has arranged for delivery of the data is run safely, by using certain security standards.After the buyer enters into a transaction, the retailer will send the goods ordered by mail directly to home buyers. Some cybershop provide facilities for the buyer to check the status of goods that have been sent over the internet.Software for Making E-CommerceIn the manufacture of 'shop' on the internet (or commonly referred to as cybershop), required specific software to organize an inventory of goods and the sale and purchase of goods. In the market, there is special software to create E-Com system, such as Intershop Intershop Communications Online output, Merchant Server from Microsoft Corp., and the output iCat Electronic Commerce Suite.Special software was sold to parties who intend to build cybershop, and sold for thousands of dollars. In general, the software for the manufacturing of E-Commerce is using the database for the preparation of the catalog. Database used is usually a DB2, Oracle, or SQL.Alternative Payments for E-CommerceFor payment, e-commerce provides many alternatives. The trick is to first register as a customer on the web. Buyers who already have a credit card can use the card for payment. In addition to credit cards, the other alternative is to use e-cash. E-cash is actually a special account for payment through the internet. The account is opened by using a credit card that belongs to the previous.Customer just need to fill in your e-cashnya to use.Another alternative in the payment on the internet is by using a smartcard. In Singapore, the smartcard known as cash cards.Smartcard usage is similar to the use of ATM cards are commonly used for shopping, which at the time of the transaction, the money is directly debited from the account at the bank. For payment on the internet, the user must have a 'smart card'. In use, a special tool is connected to the serial port on the computer. At the time of the transaction, the card must be rubbed into the smart card device, so the chip embedded in the card can be read by a computer. For software, used software called 'e-wallet'. Examples of web sites that have provided smartcard for payment is http://www.discvault.com.In addition to the three ways above, there is a relatively new payment alternative and not so popular. This alternative is the use of iCheck, the method of payment by check. These payments require customer's check number. Web site that provides an explanation of how this payment is http://www.icheck.com.Security in E-CommerceIn practice, shopping on the web requires a connection to the internet and browsers that support secure electronic transactions, such as Microsoft Internet Explorer and Netscape Navigator.Microsoft and Netscape, in cooperation with the credit card companies (Visa and MasterCard), as well as internet security companies (such as VeriSign), has made a special encryption standards that make transactions via the web to be very safe. In fact, Visa and MasterCard provide 100% security guarantee to the user's credit cardnya who use e-com.Which indicates a retailer's web site is safe or not is a special mark that appears in the status bar at the bottom of the browser screen.On IE, the sign that appears is the locked padlock sign in the right corner of the status bar. While users of Netscape Navigator, will see a key in the left corner status bar. If these signs appear, it means you're ter-connect on a secure server. However, because the standard used for secure connection is relatively new, yet all cybershop using this standard.A collection of many that have been integrated cybershop called cybermall. Some cybermall will first check the legitimacy of cybershop that will go, so as to avoid any false cybershop. Some cybermall also provide additional services, such as centralized billing or claims, to make the shopping process easier and safer.SET mechanism.Encryption standards used in e-commerce at this time is SET (Secure Electronic Transaction). Besides being used for payment by credit card, SET is also used for payment with the smartcard. By using SET, the confidentiality of customer information (either the name and card number) can be maintained. SET can also keep autotentifikasi or the seller's identity and the customer, so it can not be misused by anyone.SET uses a special encryption called asymmetric cryptography to ensure the security of a transaction. Asymmetric cryptography is also referred to as the Public-key cryptography. This encryption uses two keys / key (ie code), a key used to encrypt data, and other key to decrypt the data. Both keys are mathematically linked with a specific formula, so that the data has been encrypted by one key can only be decrypted using a key partner.Each user has two keys, namely puclic key and private key. Users can freely distribute the public key. Because of the special relationship between the two keys, user and anyone who receives the public key received assurances that the data has been encrypted with a public key and sent to the user only be decrypted by the private key. Security is assured as long as the user can maintain the secrecy of private key. This key pair must be created specifically by the user. Algorithms are typically used to manufacture key algorithm is RSA (named after the initials of the author, namely: Rivest, Shamir, and Adleman).That is, the manager of an e-commerce using the SET, must make a special key partner for the web. The public key will be distributed, and this is usually done through the deployment of a web browser.Public key is included for free for every web browser, and have been available if the browser is installed. Private keys, public key pair to pair are kept by the manager of e-com.If the buyer uses a browser to send the form the transaction, the buyer will use the public key that has been available on the web browser. Others who do not have the private key partners, will not be able to decrypt the form data sent with the public key. Once the data up to the manager of e-com, the data will be decrypted using the private key. That is, only the e-com managers who can get the data in the form of the truth, and identity data as well as customer credit card numbers will not fall into unauthorized hands.E-Com in IndonesiaUntil now, the official website has hosted e-commerce in Indonesia is RisTI Shop. RisTI, the Division of Research and Information Technology of PT. Telkom, provides a prototype e-commerce services for the provision of telecommunications equipment product information and non-telecommunications. This Web page also has supported the process online transactions.RisTI Besides, it seems there is no other web e-com held in Indonesia. In fact, to make the e-com system, investments are not issued for building an actual store. In addition, the scope of marketing its products can be much broader, because it is not confined to one particular city. In addition, the cost of providing and promoting the e-com is also smaller when compared to conventional systems that store. With a lot of things that benefit, it is expected in Indonesia will have certain parties who can create and manage e-commerce, so it will benefit all parties in Indonesia, both sellers and buyers.* Onno W. Purbohttp://www.sentralweb.com/2004/08/e-commerce
