An increasing amount of semi-structured data, XML has become fundamental to humans and programs. XML changed by the World Wide Web Consortium (w3c) is quickly emerging as a new standard language for semi-structured data representation and transfer on the Internet. XML documents usually hold private information that cannot be shared by all user communities. So securing XML data is becoming increasingly important and several approaches have been created to protect information in websites. Usage control has been considered as the next generation access control model with differentiating properties of decision continuity. It has been proven to be efficient to improve security administration with flexible authorization management. Usage control changes finer-grained control over usage of digital objects than that of traditional access control policies and models. XML schema defines format and contents of xml instance. Access control established on a schema will be transported to all its instances. Also, XML schema supplies a mechanism to build relationships between schemas and elements. We present a usage control model to protect information distributed on the web. As privacy becomes a major refer for consumers and enterprises, many research have been concentrated on the privacy protecting technology in recent years. In this paper, We present a comprehensive approach for usage access control established on the notion purpose. In our model, purpose information connected with a given data element specifies the intended use of the subjects and objects in the usage access control model. A key feature of our model is that it accepts when an access is required, the access purpose is checked against the intended purposes for the data item. We suggest an approach to represent purpose information to support access control established on purpose information. Finally comparisons with related works are analyzed.

This system facilitates mailing among the users of an internet, having an efficient and easy to communicate with telecommunications. The mails are transmitted and receiving by individual users registered in a mail management server. To prevent unauthorized to access the mail, message arrive in mail atleast one of them is deleted to store efficient mail using less storage space. There exits various applications Intranet/Internet services such as E-mail, Flip, news, telnet, archive the web-based internet/intranet service management to evaluate the performance.
