Improved pixel hiding method for steganography of gray images within color images
Steganography is the process of data hiding into a host signal with three main characteristics: imperceptibility, payload and quality of the recovered data. For images, one of the pixel modication methods is the BPHM (Block Pixel Hiding Method) which has good imperceptibility and payload, but it doe...

For images, one of the pixel modication methods is the BPHM (Block Pixel Hiding Method) which has good imperceptibility and payload, but it does not ensure the good quality of the recovered secret image. In this paper, we propose an improvement of the BPHM with the purpose to obtain similar results to the well-known QIM (Quantization Index Modulation) method. According to the results, the imperceptibility of the stego image and the quality of the recovered secret image were improved, and then, our results are closer to QIM results.El proceso de ocultar datos secretos dentro de una señal huésped se conoce como esteganografía; sus parámetros de diseño son la imperceptibilidad, la capacidad de ocultamiento y la calidad de los datos recuperados. En el caso de imágenes, uno de los métodos existentes basado en la modicación de los píxeles de la imagen huésped es el denominado BPHM (Block Pixel Hiding Method), el cual presenta una buena imperceptibilidad y alta capacidad de ocultamiento, pero no garantiza la calidad de la imagen secreta recuperada. Este artículo propone un método que mejora los resultados de BPHM basado en la selección de banda y un algoritmo de búsqueda global denominado IPHM (Improved Pixel Hiding Method). De acuerdo a las simulaciones realizadas, los resultados obtenidos con IPHM son mejores a los obtenidos con BPHM y son similares a uno de los métodos más populares en esteganografía de imágenes conocido como QIM (Quantization Index Modulation).application/pdfspaUniversidad EAFIThttp://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/3096Copyright (c) 2016 Ingeniería y Ciencia | ing.cienc.http://creativecommons.org/licenses/by/4.0Acceso abiertohttp://purl.org/coar/access_right/c_abf2instname:Universidad EAFITreponame:Repositorio Institucional Universidad EAFITIngeniería y Ciencia | ing.cienc.; Vol 12, No 23 (2016); 145-162Ingeniería y Ciencia | ing.cienc.; Vol 12, No 23 (2016); 145-162Improved pixel hiding method for steganography of gray images within color imagesMétodo de ocultamiento de píxeles para esteganografía de imágenes en escala de gris sobre imágenes a colorinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionarticlepublishedVersionArtículohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1BPHMQIMsteganographyimperceptibilityquality of the recovered secret imageBPHMQIMesteganografíaimperceptibilidadcalidad de la imagen recuperada07.05.PjRenza, DiegoBallesteros L, Dora MRincón, RamiroIngeniería y Ciencia1223145162ing.ciencORIGINALdocument (36).pdfdocument (36).pdfTexto completo PDFapplication/pdf1219712https://repository.eafit.edu.co/bitstreams/4669ab77-4ce9-4f46-a38c-cf01dc2224a9/download489793b5d7cd39fd95ac5d355aa20cbcMD52articulo.htmlarticulo.htmlTexto completo HTMLtext/html374https://repository.eafit.edu.co/bitstreams/b02b0f93-482a-4a09-aac8-b8fd340bc7a3/downloade63d5b30beedc9e602cc347c41f2ab79MD54THUMBNAILminaitura-ig_Mesa de trabajo 1.jpgminaitura-ig_Mesa de trabajo 1.jpgimage/jpeg265796https://repository.eafit.edu.co/bitstreams/bf1c4ca4-9cb5-4f0a-95fd-4010f7cfeadb/downloadda9b21a5c7e00c7f1127cef8e97035e0MD5310784/11288oai:repository.eafit.edu.co:10784/112882020-03-01 18:05:51.882open.accesshttps://repository.eafit.edu.coRepositorio Institucional Universidad EAFITrepositorio@eafit.edu.co |
