This paper extends the watermarking method introduced in [1] in order to embed watermark data into fingerprint images, without corrupting their features. Two methods are proposed. The first method inserts watermark data after feature extraction thus prevents watermarking of regions used for fingerprint classification. The method utilizes an image adaptive strength adjustment technique which res...

The multi-resolution watermarking method for digital images proposed in this work. The multiscale ridgelet coefficients of low and high frequency bands of the watermark is embedded to the most significant coefficients at low and high frequency bands of the multiscale ridgelet of an host image, respectively. A multi-resolution nature of multiscale ridgelet transform is exploiting in the process ...

This paper presents a novel watermarking scheme able to resist geometric attacks. The proposed method performs imperceptible watermarking of images in the spatial domain. To generate resistance to scaling and rotation attacks, two generalized Radon transformations of the image are introduced, while resistance to translation is accomplished through a localization of the watermarking method based...

The copyright protection of digital content became a critical issue now-a-days. Digital image watermarking is one of the techniques used to protect digital content. A novel image watermarking approach based on quantization and back propagation neural network is proposed in this paper. The cover image is decomposed up to 3-levels using quantization and DWT. The bitmap is selected as a watermark....

This paper describes a method of hiding a copyright symbol into an print image which can survive against print-scan process. Copyright protection is a challenging problem specially for printed image document. Digital watermarking is one of the most efficient method to protect an image from unauthorized use. In this paper we propose an inexpensive hardcopy watermarking technique which can surviv...

Most work on watermarking has resulted in techniques for different types of data: image, audio, video, text/language, software, etc. In this paper we discuss the watermarking of abstract structured aggregates of multiple types of content, such as multi-type/media documents. These semi-structures can be usually represented as graphs and are characterized by value lying both in the structure and ...

Road traffic monitoring using visual-based camera and real-time image processing techniques have been actively investigated over the years. Tkaffic image sequences are important information for the purpose of traffic system control and traffic accidents surveillance, for cxamplc, the determination of offending vehicles. In this paper, a semi-fragile watermarking method for authentication of tra...

Digital watermarking has been considered as an important technique to protect the copyright of digital content. For a digital watermarking method to be effective, it is essential that a watermark embedded in a still or moving image resists against various attacks ranging from compression, filtering to cropping. As JPEG is a dominant still image compression standard for Internet applications, di...

Most of the existing robust watermarking schemes were designed to embed the watermark information into the plaintext images, which leads to a latent risk of exposing information and are vulnerable to unauthorized access. In addition, the robustness of watermarking in the encrypted domain is another issue that should be taken into account. Based on Discrete Fourier Transform (DFT) and Logistic c...

The digital watermarking provides the protection against the digital data copying, proceeding distributing among the unauthorized users using easily available software. This paper gives the comparative analysis of digital image watermarking in frequency domain. The parameters used to test the robustness and transparency of the watermarking algorithm are Normalized crosscorrelation coefficient (...
