Email is a popular tool for transmitting information. The contents of email traffic can be intercepted in transit at your ISP or at Internet backbone providers such as AT&T. Email can also be intercepted as it rests on email servers. To protect the privacy of email it is necessary to encrypt it, using solutions such as PGP (Pretty Good Privacy), S/MIME (Secure Multi-Purpose Internet Message Exchange), and steganography - the hiding of information inside images. Research these different mechanisms. Armed with this background information, compare and contrast PGP, S/MIME, and steganography as mechanisms to secure email.
