“…Security can be confirmed by various encryption methods, where the key decides the degree of security. Several methods, such as chaos-based, Discrete Cosine Transform (DCT), and logistic map-based encryption techniques, have been used to ensure the security and confidentiality of the embedded watermark [24]. The security of functional magnetic resonance imaging (fMRI) images is important, as they are related to brain activities.…”

“…Their proposed method extracts the watermark by generating dynamic stochastic resonance (DSR) phenomena, ensuring imperceptibility and robustness against conventional attacks. A chaotic encryption-based blind digital image watermarking technique has been proposed, which works both for grayscale and color images [24]. The method divides the host image into 8 × 8 blocks after performing DCT operation and, then, embeds the watermark using the DCT coefficients of adjacent blocks.…”

Digital image authentication is an extremely significant concern for the digital revolution, as it is easy to tamper with any image. In the last few decades, it has been an urgent concern for researchers to ensure the authenticity of digital images. Based on the desired applications, several suitable watermarking techniques have been developed to mitigate this concern. However, it is tough to achieve a watermarking system that is simultaneously robust and secure. This paper gives details of standard watermarking system frameworks and lists some standard requirements that are used in designing watermarking techniques for several distinct applications. The current trends of digital image watermarking techniques are also reviewed in order to find the state-of-the-art methods and their limitations. Some conventional attacks are discussed, and future research directions are given.

With the invent of better signal processing operations unveiled by the research community of both communication and signal processing, the Telemedicine is becoming more and more prominent all over the world. Communicating the data captured from the patient to the clinicians in non-recognizable seconds of time is crucial in many cases so as to take a right decision at right time. Then the processing of the data sent to clinicians is the second part of telemedicine where extensive processing capabilities are required. In this paper, the first part of telemedicine is answered by devising diversified schemes using wavelet and modification of standard coding scheme embedded zero tree wavelet (EZW). First, coding by EZW and Set partitioning in Hierarchical tree (SPIHT) was implemented. Then, new wavelets and their lifting versions are designed. Finally, two variations of standard EZW scheme were proposed. The simulation results suggest that the techniques presented in this paper provide better compression performance at different levels of compression ratio (CR) and peak signal to noise ratio (PSNR). In addition to CR and PSNR, bit error rate and output bandwidths are calculated.

“…Para agregar robustez e segurançaà marca d'água há duas técnicas comumente aplicadas: a inserção aleatória de bits de marca d'água em posições da imagem ou de sua transformada; e a cifragem da marca d'água. Ambas podem ser incorporadas a um algoritmo de marca d'água com a utilização de mapas caóticos [9]- [13]. Esses mapas são caracterizados por possuírem sensibilidadeà condição inicial e comportamento pseudo-aleatório, apesar de serem determinísticos, o que se traduz em trajetórias (ou sinais) assemelhadasà ruído [14].…”

“…Esses mapas são caracterizados por possuírem sensibilidadeà condição inicial e comportamento pseudo-aleatório, apesar de serem determinísticos, o que se traduz em trajetórias (ou sinais) assemelhadasà ruído [14]. Os mapas caóticos são empregados para embaralhar os bits de marca d'água [9]- [11] (agregando segurança ao método), bem como para definir as posições na imagem em que serão inseridos estes bits [12], [13] (agregando robustez ao método). Para suportar uma distorção severa impostaà imagem, códigos corretores de erro podem ser aplicados para tornar a marca d'água mais robusta [15]- [18].…”

Resumo-Este artigo descreve um esquema de marca d'água robusto. Os bits inseridos na imagem são os bits de paridade de um código corretor de erro cuja mensagemé formada pela combinação dos bits de marca d'água com bits caóticos. Uma estratégia que propicia robustez e segurançaà marca d'água. A inserção se dá em frequências específicas da transformada discreta do cosseno da imagem. A robustez do método propostó e testada para vários ataques utilizados em processamentos de sinais e ataques geométricos. Comparações com resultados da literatura revelam que a técnica proposta apresenta maior imperceptibilidade e robustez. Palavras-Chave-Marca d'água robusta, códigos corretores de erro, mapas caóticos, ataques geométricos.
