Ancillary data and metadata substitution.

Generation (suspicious because of the traceability of the generated carriers).

Injection (suspicious because of the content-unrelated file size increment).

Different file formats are modified in different ways, in order to covertly insert hidden data inside them. The carrier engine is the core of any steganography tool.

using a different cryptography algorithm for each carrier and choosing it with a chain-order-dependent equiprobabilistic algorithmĬhi-square image steganalysis Carrier engine.

using a different initialization vector for each carrier and storing it inside processed carriers -> CryptedIVn = Crypt( IVn, CryptedIVn-1 ).

This additional security feature usually is achieved by: Hidden data may be split among a set of files, producing a carrier chain, which has the property that all the carriers must be available, unmodified, and processed in the correct order in order to retrieve the hidden data. eBay, Facebook, spam, etc.) provides ample opportunity for covert information±. The sheer volume of modern (ca 2014) and inane high-bandwidth media (e.g.,, bittorrent sources. For instance, if the least-significant-bits of the red camera-pixel channel of an image has a Gaussian distribution given a constant colored field, simple image steganography which produces a random distribution of these bits could allow discrimination of stego images from unchanged ones.

There is a weaker requirement that the embedded message not change the carrier's statistics (or other metrics) such that the presence of a message is detectable. This is because the publicly available source data could be compared against the version with a hidden message embedded. photo) is original, not a copy of something publicly available (e.g., downloaded). It is a cryptographic requirement that the carrier (e.g.
