Image-Based e-Document Authentication
نویسندگان
چکیده
Fingerprint verification is one of the most reliable personal identification methods. With the fast development of the Internet, the usage of e-documents becomes more popular. Nonetheless, the old way of putting fingerprints or stamps on a hardcopy is no longer possible for e-documents. In this paper, a document fingerprinting and de-fingerprinting system is presented. In the document fingerprinting system, a thinned fingerprint image is compressed and embedded in an edocument in the spatial domain. A conversion to image format is needed if the e-document given is in PDF format. The document defingerprinting system does the reverse operation. Our experimental results show that the distortion after embedding is almost invisible and the embedding capacity is sufficiently large to embed a compressed thinned fingerprint. The results are encouraging to make it possible in practice for document authentication.

Image authentication using LBP-based perceptual image hashing
Feature extraction is a main step in all perceptual image hashing schemes in which robust features will led to better results in perceptual robustness. Simplicity, discriminative power, computational efficiency and robustness to illumination changes are counted as distinguished properties of Local Binary Pattern features. In this paper, we investigate the use of local binary patterns for percep...

متن کاملDocument Image Dewarping Based on Text Line Detection and Surface Modeling (RESEARCH NOTE)
Document images produced by scanner or digital camera, usually suffer from geometric and photometric distortions. Both of them deteriorate the performance of OCR systems. In this paper, we present a novel method to compensate for undesirable geometric distortions aiming to improve OCR results. Our methodology is based on finding text lines by dynamic local connectivity map and then applying a l...

In this paper we present Document analysis and classification system to segment and classify contents of Arabic document images. This system includes preprocessing, document segmentation, feature extraction and document classification. A document image is enhanced in the preprocessing by removing noise, binarization, and detecting and correcting image skew. In document segmentation, an algorith...
متن کاملIntelligent scalable image watermarking robust against progressive DWT-based compression using genetic algorithms
Image watermarking refers to the process of embedding an authentication message, called watermark, into the host image to uniquely identify the ownership. In this paper a novel, intelligent, scalable, robust wavelet-based watermarking approach is proposed. The proposed approach employs a genetic algorithm to find nearly optimal positions to insert watermark. The embedding positions coded as chr...
