SECURED WEBPORTAL FOR ONLINE SHOPPING

ABSTRACT

An online shopping system permits a customer to submit online orders for items and/or services from a store. Usually, online shopping products are displayed and maintained on a web portal. A Web Portal is a type of Website. A Web Portal acts as a gateway to the internet. Web portals provide a single point of access to a variety of content and core services, and ideally offer a single sign-on point.

The main challenge for online shopping portals is to provide security for the transactions involved. Customers, usually need to enter their crucial information such as, credit card number, debit card number etc. to buy products. Today, most of the shopping portals make use of Secured Socket Layer (SSL) to transfer crucial data. Existing system was capable of providing a very good end-to-end security. But, it cannot encrypt only a part of information; hence a large cipher text is generated.

To, address the issues not considered by the current system, a new system is proposed here, which makes use of XML encryption to provide security. XML Encryption is intended to provide security for transactions by generating a compact cipher text, which is transferred over the net as an XML document.

In the project work  the development of secured web portal is undertaken. Online shopping portals are a new face of our real time market hence must be designed in a creative but simple manner so that it is easy for the users to transact from it. There is a need to analyze this new “player” by applying the XML encryption technique which provides end-to-end security for applications that require secure exchange of structured data.

INTRODUCTION

1.1 E-Commerce

“Commerce refers to the all activities surrounding the purchase or sale of goods or services.” The various activities include Marketing, Sales, Payment, Fulfillment and customer service these activities applies to the business done on the web. E-Commerce refers to the process of buying or selling a product or service over an electronic network i.e. an Internet.

E-Commerce encompasses three types of business transactions.

1. B2C E- Commerce: This type can occur between a business and consumer. Example: A business that engages between B2C E-Commerce is ‘Amazon’. Amazon promotes itself as the “place to find and discover anything a user wants to buy online” i.e. by selling videos, books, CDs to the consumer.

2. B2B E-Commerce: This type can occur between one business and another business. Example: a company that engages in B2B IS Cisco system. Cisco system creates much of the physical    infrastructure of the internet that allows businesses to communicate.

3. C2C E-Commerce: This type can occur between two consumers. Example: this type of   E-Commerce is eBay. eBay enables its customers to auction items to other customers. eBay collects fee from every transaction.

Database: This acts as a storage container that holds information about the items
that merchants sell (products, prices, manufacturers, etc.)

Shopping Web Site:  This is a web site that enables to modify the information in the database (update prices, add new items, delete old items, etc.)

Public Web Site:  This is the web site that displays and describes merchant’s products to the customers. From this web site merchandise can be securely purchased by anyone in the world.

Step 1:  In the diagram above, Step 1 shows the arrow flowing out of the database into a shopping web site. In other words, all of the information about the products, prices, manufacturers, etc will be displayed in easy to read lists inside the web browser. User can access these lists from anywhere in the world, not just from inside his office.

Step 2:  This step shows the arrow flowing from the shopping web site into the database. As mentioned in Step 1, products information is displayed in the form of lists inside the web browser. Each individual item, on each list is editable. That means that merchants can change prices, add new items, and delete old items, etc from anywhere in the world.  All of merchants “updates” to these lists are instantly stored in the database. This functionality empowers merchants to administer their own web site allowing them to avoid web site maintenance fees and service time when all they want to do is make a change to their product line.

Step 3:  The final step shows the information that merchants have stored in database flowing into the Public web site. With all editing complete, merchants have the confidence in knowing that their customers are seeing accurate and up to the minute products and price information.
