Hiding Messages In VoIP Packets
Orome1 writes "A group of researchers from the Warsaw University of Technology have devised a relatively simple way of hiding information within VoIP packets exchanged during a phone conversation. The called the method TranSteg, and they have proved its effectiveness by creating a proof-of-concept implementation that allowed them to send 2.2MB (in each direction) during a 9-minute call. IP telephony allows users to make phone calls through data networks that use an IP protocol. The actual conversation consists of two audio streams, and the Real-Time Transport Protocol (RTP) is used to transport the voice data required for the communication to succeed. But, RTP can transport different kinds of data, and the TranSteg method takes advantage of this fact."
You can avoid your messages being intercepted using this technique simply by piggybacking it on the one protocol that large telcos in every country are trying to find ways to block. Hooray!
OK, I'm being an ass. It's a cool concept.
You are not alone. This is not normal. None of this is normal.
Women have been hiding messages in voice streams in like forever.
That's easy.
Alice is secretly a BDS&M dominatrix, into humiliation, flagellation, and golden showers. She also is president of the knitting club, and a well respected member of her local orthodox church.
Bob is secretly a masochist with a diaper fettish, and gay bestiality, and also the mayor who has openly critised alternative lifestyles to appease the conservative demographic of his constituency.
Eve is the reporter for the local tabloid, who suspects Alice and Bob of shennanigans, since they seem to spend inordinate amounts of time together, and always seem to be missing or unavailable at the same times. Hopes to gain subversive access to the private correspondences of Alice and Bob as part of her scoop. .........
That's aways the way I envisioned the "alice, bob, eve" scenario anyway...
