Reliable Information Hiding Based on Support Vector Machine

摘要

Darbe siūloma patikimo informacijos slėpimo schema, kurios pagrindą sudaro atraminių vektorių metodas ir klaidas taisantys kodai. Informacijos slėpimas modeliuojamas kaip suspausto vandenženklio vaizdas. Paslėptosios informacijos ištraukimas nagrinėjamas kaip skaitmeninio signalo perdavimo ryšio kanalu uždavinys. Siūlomos schemos patikimumas tikrinamas įvairiomis atakomis. Aprašytų straipsnyje eksperimentų rezultatai rodo gerą pasiūlyto metodo patikimumą.%In this paper, a reliable information hiding scheme based on support vector machine and error correcting codes is proposed. To extract the hidden information bits from a possibly tampered watermarked image with a lower error probability, information hiding is modeled as a digital communication problem, and both the good generalization ability of support vector machine and the error correction code BCH are applied. Due to the good learning ability of support vector machine, it can learn the relationship between the hidden information and corresponding watermarked image; when the watermarked image is attacked by some intentional or unintentional attacks, the trained support vector machine can recover the right hidden information bits. The reliability of the proposed scheme has been tested under different attacks. The experimental results show that the embedded information bits are perceptually transparent and can successfully resist common image processing, jitter attack, and geometrical distortions. When the host image is heavily distorted, the hidden information can also be extracted recognizably, while most of existing methods are defeated. We expect this approach provide an alternative way for reliable information hiding by applying machine learning technologies.
