On the other hand establishing hidden communication is an important subject of discussion that has gained increasing importance nowadays with the development of the Internet. One of the methods introduced for establishing hidden communication is steganography. Therefore steganography in MMS is an interesting idea. One of the problems in steganography methods is the security of transferring password key used for steganography between sender and receiver of secure data. In this paper a new method is proposed for solving this problem using CAPTCHA method through MMS messages. In this method the password key is spoken in an audio file and the data are hidden in the image by this password key. Then the image and audio files are inserted in a MMS message and sent to the receiver. Therefore the human receiver can recognize the password from the audio file and extract the data from the image using this password, but the computer cannot recognize the spoken word from the audio file and extracting the password. By this method the user does not need to memorize any password for extracting the data. This method has been implemented in J2ME programming language.","PeriodicalId":167980,"journal":{"name":"2007 International Conference on Information and Emerging Technologies","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134482177","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}

Robustness is one of the main requirements for many watermarking applications. In this paper a blind discrete wavelet transform (DWT) based video watermarking algorithm for copyright protection is proposed. We have embedded a meaningful watermark invisibly into uncompressed video. The watermark is embedded in high frequency sub-band coefficients of the DWT to improve the invisibility of the marked video sequence. The watermark is first scrambled and then encoded to minimize the error probabilities during watermark detection. We have applied 2-D automorphic transform and BCH error correction coding on the binary image for scrambling and encoding the watermark respectively before the watermark embedding. We have applied key based pseudo random 3-D interleaving on the coefficients selected for watermark insertion. We have also embedded the frame number as the synchronization information instead of using the sliding correlation as proposed in [1, 5]. Experimental results have proved that the embedded data with the proposed scheme is visually transparent, robust against unintentional or malicious attacks such as frames deleting, frames inserting and frame statistical averaging. 3-D interleaving has significantly improved the robustness of the proposed scheme against temporal attacks. The watermark embedded in such way is high bit rate and thus more robust. The series of experiments conducted has revealed the effectiveness and usefulness of the proposed watermark generation and embedding strategy.","PeriodicalId":167980,"journal":{"name":"2007 International Conference on Information and Emerging Technologies","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132337620","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}
