The Internet, we are all aware, has become a part of everyday life. Internet is the need for most transactions worldwide, he is one of the best means of communication is the best way to reach the masses and that is the gift that technology has made the world a small place to live. Emails are part of the Internet. They serve as communicators between friends worldwide. For me, the emails are options like the idea of penfriending of antiquity. Emails travel along the network, take the right path and reach the intended recipient. They help you stay in touch with close friends in this hectic life of today. Since e-mails are so important for people of the computer all warnings, email privacy became an issue as important. Email privacy issues when it comes out to send plain text on the Internet. Let us look at the issues of email privacy in detail.

• Email Privacy Issues

Mails contain headers and tracking e-mails includes the analysis of information in e-mail header. A header of the email contains the message source and a list of all the points along which the mail traveled. The examination of a mail header may provide information about the sender that the address as the machine’s IP sender. In addition, an e-mail travels through many computers across the network is vulnerable to gain access by intruders.

Second, spam, the question most irritable, is also a problem of email privacy. Spam mails eat huge amounts of bandwidth and frustrate receivers. unsolicited messages are often used to force users to reveal their personal information. Spam is commonly used to request information that can be used by the attackers. Trojans can attack a computer system so dangerous. They are powerful enough to give the attacker full access to the computer system of a user. Trojans are programs that log keystrokes of the user, which piracy of personal information and passwords typed through the computer system.

The backup emails from unauthorized access and inspection is known as electronic privacy. Much of the Internet is vulnerable to attacks. Emails travel through the paths unprotected Internet, thus becoming vulnerable to hacker attacks. E-mails are subject to unauthorized access, disclosure of confidential information over the network, thus violating the confidentiality of messages. E-mails are susceptible to eavesdropping. They travel through several routers and smaller networks and if not screened, are bound to be attacked. An inadequately protected router can serve as a means of unauthorized access to emails. Clever software can screen e-mail content very easily. Also email receivers tend to undermine privacy by e-mail indiscriminate transmission of emails. Indiscriminate transmission is often responsible for the disclosure of contact information and the names of all those who email in that thread.

Technology has proposed solutions to the problems of email privacy. The issues have been resolved to some extent by the successful implementation of security measures. Security measures include cryptography, digital signatures and the use of secure protocols that can ensure the confidentiality of emails to a certain extent.

PGP (Pretty Good Privacy) is a standard encryption algorithm that encrypts and decrypts the e-mail. This encryption standard is a part of most operating systems today. E-mail Encryption is another method that achieves confidentiality of messages. It is achieved through public key cryptography. Common methods for encrypting email S / MIME, OpenPGP and TLS.

Digital signatures provide us another way to ensure the confidentiality of messages. A digitally signed electronic message to the receiver confirms the identity of the sender, which allows the confidentiality of messages. An electronic document is digitally signed assurance unspoiled nature and original content e-mail. This email spoofing technique fighting, which involves manipulation of mail header to the e-mail appears to come from another source.

authentication methods are used to power electronic messages with verifiable information sufficient for the receiver to recognize the nature of incoming messages. In an effort to stop spam, identity of an e-mail address must be verified. The Transmission Control Protocol and IP address registries to help recipients of e-mails to check the IP addresses of the sender. Blacklisting attempts to separate the IP addresses that are spammers who intend to violate the confidentiality of messages. But because of the use of dynamic IP addresses, blacklisting can not be a foolproof plan to fight against the problems of email privacy.

The technology has raised questions email privacy and intelligence of man has managed to find remedies for them. But when it comes to protecting the privacy, ethics is something which matters most
