Tutorials XMLThe Universal Resource Identifier or the URI is used to identify the object and it uses the URI reference. The URI attributes and the XML follow the same set of characters which is called the Unicode. And the disallowed characters are converted into Octets. The URI follows a specific reference processing model.
If a certain data type has octets then the signature application will make an attempt to parse the octets. If the data type is a node set then the signature application has to attempt to convert the node sets into octets using the canonicalization method and then parse the octets.
Sometimes the reference validation may fail if the fragments processing has not been done in a standardized way. The proxies will not validate them.
On the internet the control parameters are established to recognize who can access the information and why they are accessing the information because in many cases information that is critical to a business is being divulged. The control or access control is established by two components.
The authentication component identifies the person and who is accessing the information. The authorization component establishes the reasons and what the person is allowed to do with the information. Basically both these processes ask these questions, who are you? And what are you allowed to do?
In e commerce business transactions are highly complex and they are carried out across several varied platforms and servers, information is exchanged between many servers due to which security has become very complicated. These two components of the XML security achieve the standards of keeping the data secure in a simple fashion.
What exactly does the Authorization component do? It breaks down information further into questions; one is policies and second is distribution. At the policy level it analyzes the data from different sources and looks into it carefully to declare authorizations and rules related to who can do what. At the distribution level it decides who can do what and then distributes the rights to the applications to carry out their tasks.
Credit rating: A number of authorization services which are at premium level are available and they provide information like credit ratings, approvals, rejections etc; you need certain interfaces to carry out the transactions and access this data. XML security uses the authorization here for these kinds of business services.
Exchange of business information: Exchange of information between businesses needs authorization and authentication. This exchange of information is possible using the XML security process
Data related to health Care: health care data is treated with care and needs to be extremely confidential. The health care services are common but much fragile and need to be secure too. There should be immediate accessibility also. Security can be created here even as information is being passed from one provider to another and the access can be controlled at the same time.
Another important feature in most business transactions is exchange of money. XMLPay is a web service which enables a payment gateway. It provides connectivity to major financial institutions. It is useful to both Business to consumer and Business to Business portals. XML Pay enables point to point business transactions and enabling business organizations to carry out e commerce transactions freely over the web and avoiding the need to use the legacy payment technologies.
The XML is useful especially when the buyer needs to forward an X amount to the seller and the seller needs to record that payment using a payment processor. The typical XML components involved in a payment transaction are XML pay core which has the basic data types that go into a business transaction between business operations. This function is the heart of the XML pay system. XML Pay registration captures all information that is exchanged while registration or enrollment and also configuration. XML pay reports gather all the payment information and then reports the payment so that the transaction can be carried out successfully and securely.
