Research at the edge of computational social science
We use lexicography, historiography, information forensics, meta-analysis and disciplinics to study structure, dynamics and resilience of real-world systems.
The Psic Effect
The Psic Effect of linguistic steganography. The term “Psic Effect” was coined by Zhongliang Yang and Zhiwen Hu. Herein, ‘psic’ is a blend of ‘perception’ and the Latin ‘sic’ (‘in such a way’). The Psic effect, which is often linked to both perceptual-imperceptibility and statistical-imperceptibility, is a conflict phenomenon of generative steganography –– the quality of the generated carrier is gradually getting worse with the increase of the embedding rate, whereas its anti-steganalysis ability is gradually increasing. The abscissa represents the average number of bits embedded in per word (bpw). The orange line indicates the calculated mean perplexity (the smaller, the better) of these generated steganographic sentences. The size and transparency of the dots represent the average human score (the larger, the better), with the specific score at the top. The blue line represents the steganographic detection accuracy (the lower, the better) under different embedding rates.
