Este artigo propõe um novo método de autenticação de imagem reversível que não memoriza os parâmetros para extrair dados de autenticação incorporados de uma imagem. O método proposto, uma vez que distorce uma imagem para ocultar dados para autenticação na imagem, ele recupera a imagem original da imagem distorcida, a menos que seja aplicada adulteração à imagem, ou seja, reversível. Ao comparar os dados extraídos e os dados gerados a partir da imagem restaurada, este método detecta a adulteração da imagem e localiza ainda mais as regiões adulteradas pela unidade do bloco. O método proposto extrai dados ocultos sem memorização dos parâmetros utilizados em seu algoritmo. Esta característica torna o método proposto prático. Considerando que qualquer método de memorização de parâmetros enfrenta graves problemas com armazenamento e gerenciamento de parâmetros, de acordo com o aumento no número de parâmetros memorizados que é causado pela localização precisa de adulteração e/ou pela aplicação a um grande número de coleções de imagens, por exemplo, vídeo sequências. Os resultados da simulação mostram a eficácia do método proposto.

Abstract: This paper proposes a novel reversible image authentication method that does not memorize the parameters for extracting embedded authentication data from an image. The proposed method once distorts an image to hide data for authentication into the image, it recovers the original image from the distorted image unless tamper is applied to the image, i.e., reversible. By comparing extracted data and data generated from the restored image, this method detects image tampering and further localizes tampered regions by the unit of block. The proposed method extracts hidden data without memorization of parameters used in its algorithm. This feature makes the proposed method practical. Whereas any method memorizing parameters faces severe problems with storage and management of parameters, according to the increase in the number of memorized parameters that is caused by serving accurate tamper localization and/or by applying itself to a huge number of image collection, e.g., video sequences. Simulation results show the effectiveness of the proposed method.
