Windows Forum / Outlook Express / General Topics / March 2008bcc - is it really secure?
Is sending someone a "bcc" copy really secure? I have heard it said that sophisticated software can decode "bcc". Would anyone know? I would imagine that NSA and GCHQ would have no problem. It is useful sometimes to send someone a "blind carbon copy" - an old typewriter phrase - but it may be insecure. Derek All the alphabet agencies would have no problem doing it. I have a friend that works with computers at Naval Air Station, North Island, and he can do it, but with the help of the Navy's tools at his side. The average person would not be able to do it so fast.  SignatureBruce Hagen MS-MVP Outlook Express Imperial Beach, CA > Is sending someone a "bcc" copy really secure?

Just spent 1 week cleaning up the mess WUpdate made preventing hypothetical security problems. http://microscum.com/comsense/ > Is sending someone a "bcc" copy really secure? How could a "BCC:" list be "more secure" than an ordinary list? The answer is, "No". > I have heard it said that sophisticated software can decode "bcc". You have heard wrong. BCC: is not a method of encoding information, it is a method of sending email to a list of recipients. An email sent to a BCC: list is no more secure than an email sent to a "CC:" list. > Would anyone know? If you think about what "BCC:" accomplishes, the answer is as plain as the unecoded text in an email. > I would imagine that NSA and GCHQ would have no problem.

All that BCC: does is to suppress the recipient list. No recipient knows who any of the other recipients are. Nor is there any way for any recipient to learn who any of the others is.

The object of BCC is to protect the address of the recipient from spammers and other on the mailing, not to make the email itself secure. >> Is sending someone a "bcc" copy really secure? > [quoted text clipped - 20 lines] > knows who any of the other recipients are.

I had always thought that the function of BCC was to suppress the recipient list; nothing more. I just don't see how "security" factors in to this.
