This article examines the basics of customer server architecture and its privacy, such as why customer-server architecture is required and superior to others. This paper discusses the problems of MCC (Mobile Country Code), privacy and the various tasks associated with online application safety. In this article, we examined the depth of the client's server architecture, where clients transmit the requests required by the users of logic modules and secure web logging against client logging in clients. With complete distribution applications which employ computer power wherever it is accessible and give information wherever it is necessary, everybody will in future be able to use inexpensive and efficient desktop technology. In future, owners and registered users will have access to information to avoid the need for expert systems developers and their complicated programming languages. Information will be captured at source and immediately made available in the future to authorized users.
