{"title":"Improvements of StegErmelc Steganographic Method Using Hybrid Recursive Matrix Encoding","authors":"Koksheik Wong, Kiyoshi Tanaka","doi":"10.11371/IIEEJ.38.723","DOIUrl":"https://doi.org/10.11371/IIEEJ.38.723","url":null,"abstract":"> This paper proposes hybrid data representation schemes to improve the performance of a DCT-based steganographic method called StegErmelc . Even though StegErmelc simultaneously achieves scalable carrier capacity, high embedding efficiency, and low SDR (stego detectable rate), SDR of StegErmelc increases sharply when the embedding rate is increased to more than 0.10bpc. SDR of StegErmelc also varies significantly when using different parameters. To suppress the sharp increase of SDR and to reduce the performance gap when using different parameters,we propose a new algorithm that keeps as many blocks that are operating in block mode as possible, and changes their encoding modes, one at a time, to gradually and accurately increase their carrier capacities. Experimental results show that,when embedding the same amount of information,the proposed method achieves lower SDR than that of StegErmelc and the performance gap of the proposed method is also found to be smaller than that of StegErmelc. The proposed method stays undetectable when embedding up to0.125bpc. Basic performance of StegErmelc is also confirmed to be consistent regardless of the image database in use.","PeriodicalId":153591,"journal":{"name":"The Journal of the Institute of Image Electronics Engineers of Japan","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114847803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little attention has been given to the optimal position in the frequency domain for embedding watermarks. In general, there is a tradeoff between the quality of the watermarked audio and the tolerance of watermarks to signal processing methods, such as compression. In the present study, a watermarking method developed for a visual image by using a wavelet transform was applied to an audio clip. We also improved the performance of both the quality of the watermarked audio and the extraction of watermarks after compression by the MP3 technique. To accomplish this, we created a multipurpose optimization problem for deciding the positions of watermarks in the frequency domain and obtaining a near-optimum solution. The near-optimum solution is obtained by using a genetic algorithm. The experimental results show that the proposed method generates watermarked audios of good quality and high tolerance to MP3 compression. In addition, the security was improved by using the characteristic secret key to embed and extract the watermark information.","PeriodicalId":153591,"journal":{"name":"The Journal of the Institute of Image Electronics Engineers of Japan","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133285908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
