Abstract Several embodiments of computer security systems are described and which are adapted to grant an authorized individual access to a secured domain, such as a computer or data stream. In one embodiment, the security system comprises: an analyzing means for receiving first and second passwords, each of said passwords being transmitted over a first communication channel, analyzing said first password, transmitting a first signal output only if said first password is authorized, and granting access to said secured domain only if said second password is substantially identical to a code; and a random code generating means for generating said code, transmitting said code over a second communication channel upon receipt of first signal output, and transmitting said code to said analyzing means; and a notification means for receiving said code and for notifying said authorized individual of the identity of said code.
A method to securely transmit data having a plurality of bits, said method comprising the steps of: interspersing a plurality of filler data bits into said data in a certain random pattern: transmitting said data and said interspersed filler data; receiving said data and said interspersed filler data; and discarding said interspersed filler data.

A method to securely transmit data having a plurality of bits, said method comprising the steps of: interspersing a plurality of filler data bits into said data in a certain random pattern: transmitting said data and said interspersed filler data; receiving said data and said interspersed filler data; and discarding said interspersed filler data.
Claim 3
Independent Claim
54 words
A method to securely transmit data having a plurality of bits, said method comprising the steps of: interspersing a plurality of filler data bits into said data in a certain varying pattern: transmitting said data and said interspersed filler data; receiving said data and said interspersed filler data; and discarding said interspersed filler data.
Claim 4
Independent Claim
54 words
A method to securely transmit data having a plurality of bits, said method comprising the steps of: interspersing a plurality of filler data bits into said data in a certain varying pattern: transmitting said data and said interspersed filler data; receiving said data and said interspersed filler data; and discarding said interspersed filler data.
Claim 5
Independent Claim
63 words
A method to securely transmit data having a plurality of bits, said method comprising the steps of: interspersing a plurality of filler data bits into said data in a certain pattern: periodically varying said certain pattern of said filler data bits; transmitting said data and said interspersed filler data; receiving said data and said interspersed filler data; and discarding said interspersed filler data.
Claim 6
Independent Claim
63 words
A method to securely transmit data having a plurality of bits, said method comprising the steps of: interspersing a plurality of filler data bits into said data in a certain pattern: periodically varying said certain pattern of said filler data bits; transmitting said data and said interspersed filler data; receiving said data and said interspersed filler data; and discarding said interspersed filler data.
