Due to the increasing number of electronic documents as well as the conversion of paper documents to electronic ones, the use of information and communication technology changes the way of doing work in organizations and leads to a much greater dependence on electronic records. Electronic document management helps organizations to utilize information more effectively and to support the immediate operational needs for business information. An electronic records management system should be able to manage electronic records throughout their life cycle, from recording, integrity, authenticity, deletion and availability, and at the same time, one of the problems is authentication and preservation of intellectual works for electronic files. To solve such problems, we can use new methods in this direction, one of these methods is the use of steganography and watermarking. Steganography has been widely used in the past decade. Steganography and watermarking methods are designed to embed sequences of hidden information in electronic objects for various purposes, which are used in the fields of security and protection in order to hide the original message or preserve the spiritual works. This paper first studies a common understanding of EDMS concepts and, in the next step, shows the current research in the field of information embedding methods in electronic documents.

Being stil MoreBackground and aim: Anthropogenic water scarcity is among global concerns which threats the sustainability of the world in future. Overexploiting limited blue water resources for supplying human’s growing food demand is the main root of such a scarcity. Being still in its infancy, water footprint (WF) benchmarking is a proper method to determine the inefficient fraction of water consumption. Hence, we assessed if achieving benchmark levels can limit agricultural WF to its sustainable cap in Khuzestan province, which is the agricultural backbone of Iran.Method: The research consists of three stages including WF accounting, and sustainability and efficiency assessment. First, consumptive and degradative WFs were accounted for 32 in counties of Khuzestan province over the period 1986-2016. Green and blue WFs were accounted by dividing green and blue evapotranspiration by crop’s yield, respectively. The AquaCrop model was used to simulate daily evapotranspiration, and then, seasonal values were estimated by aggregating daily values. Grey WF was estimated for the applied nitrogen fertilizer in croplands. In the next stage, the sustainability status of water consumption pattern was assessed by dividing overall blue WF by blue water availability. The latter was estimated by subtracting environmental flow requirements from natural runoff. Thereafter, WF benchmarks were extracted for 10th, 25th, and 50th level of crop production, and based on which, the inefficient fractions of blue WFs were estimated for individual crops. Finally, inefficient blue WFs were compared with unsustainable ones to know if achieving benchmark levels can limit agricultural blue water consumption to its sustainable caps in the study area. A correlation assessment was also done to determine the main roots of inefficiency in Khuzestan province.Results: Along with a 63% increase in crop production and 53 increase in unit blue WF, the overall blue WF increased by 80% over the study period. Such an increasing pattern caused groundwater overexploitation with an annual average rate of 12 million m3 y-1. The contribution of green WF in consumptive WF decreased from 60% in 1986 to 48% in 2016. Overall grey WF, however, followed a decreasing trend, with an average annual decreasing slope of 140 m3 ha-1 y-1, which mainly occurred by a considerable reduction in cash crop’s grey WF. In 2016, a total of 0.98 billion m3 of blue water was consumed unsustainably, which was roughly 85% higher than one in 1986. The number of countries with unsustainable water consumption also increased from 2 counties in 1986, to 9 counties in 2016. Stable crops had the largest contribution in unsustainable WF. Based on the results of efficiency assessment, and considering WF benchmarks developed at 25th of crop production level, inefficient blue WF varies in the range of 0.26 to 606 million m3 y-1 in different counties in 2016. Compared with 1986, the inefficiency increased by 10-3860 m3 ha-1 in 16 counties in 2016. While achieving benchmark levels can reduce blue WF to its sustainable level at provincial scale, unsustainable blue WFs in Andimeshk and Ramshir counties are still 6.8 and 340.9 million m3 higher than the inefficient blue WFs, respectively. The correlation assessment showed that inefficiency increase along with any increase in added value by agricultural production and/or export, unit blue WF, blue water scarcity level, and access to groundwater consumption; while it decreases with any increase in the number of employees per ha, crop yield, and cash crop’s harvested area.Conclusion: WF assessment showed that crop production in Khuzestan province is done at the cost of deteriorating environment, which threats the stability of agricultural system in near future. While achieving benchmark levels helps with being limited to sustainable WF caps through removing inefficient blue WF fractions, there are still the risk of unsustainability in some regions, which indicates the importance of high-resolution assessments for determining hotspots. Hence, further research is required to determine temporal hotspots as well, in order to implement a proper sustainable development plans. Manuscript profile -

The embedding process is based on decomposing of pyramidal directional filter bank and triangular matrix, while the watermark extraction process is based on Mamdani fuzzy logic. In this design, in order to obtain efficient robustness and transparency, the Harris hawks optimization algorithm is used to find the best value of embedding factor. For this purpose, in the embedding algorithm, pyramid directional filter bank decomposition is utilized and accordingly the approximation sub-bands are divided into 8*8 non-overlapping blocks. Moreover, by decomposing the triangular matrix, which embeds the watermark bits in the matrix element, the use of Mamdani implication and the product inference engine have led to an efficient watermark extraction. The simulation results show that the quality of the watermarked image is equal to 60.6dB. Furethermore, applying the proposed algorithm is strong against attacks. Manuscript profile -

In order to evaluate the effects of physiographic factors of land and road forms on timber marking for the logging, the multiple linear regression model was used in the Forestry Plan Series 2 in the seventh zone of forestry plans of Nekachoub Company, Mazandaran province. For this purpose, the location of marked trees was determined using GPS in a plot with an area of 215 hectares. Then, maps of marked trees, altitude, aspect and slope percent, soil and distance from the road were prepared in GIS environment using these points and digital elevation model of study area. To understand the relationship between factors and marked trees, the multiple linear model was used. So, maps of mentioned factors and marked tree's location were entered into the regression model as independent and dependent variables, respectively. The model results showed that the timber marking activity was done more in the areas with low altitude, gentle slope and deep soils on northern and eastern directions near the forest road as compared to the other areas. Timber marking is affected by some physiographic factors, and such elements as slope or adjacency to the road may make the timber marker to interfere in these areas and avoid working in the areas with higher slope or away from the road; it leads to an uneven interventions throughout the forest as well as an unbalanced reclamation of forest structure.

As a result, embedding information about the original producer and distributor in digital images and video attracted great attention for digital right management. Watermarking provides the facility to embed the required information in images and videos. Robust watermarking is used for embedding authentication information and hence should be robust against various attacks. On the other hand, in fragile watermarking the embedded data should be destroyed by any alteration in the watermarked image or video. Reversible digital watermarking techniques are proposed for lossless restoration of the original image from the watermarked image. Watermarking is non-blind when a copy of the signature or other related information is required for extracting the signature from the watermarked image or video and is blind when the signature can be extracted from watermarked data without any other subsidiary information. Watermarking the signature in a group of successive frames of a video file by the use of 3-D transforms attracted attention because it makes the watermarked video more robust against attacks such as frame averaging and alteration, and watermarking by 3-D transform is employed as a solution to the problems caused by independent watermarking of signature in one or several frames.Methods: Contourlet transform offers a high degree of directionality and anisotropy besides the multi-scale and time-frequency localization properties in wavelet transform. As a result, Contourlet transforms the representation of curved edges in the images with smoother contour and fewer coefficients compared to the wavelet transform. In this paper, a blind robust watermarking method based on a hybrid 3-D transform is proposed. The hybrid 3-D transform is derived by employing the 2-D Contourlet transform along with the 1-D wavelet transform. The signature will be watermarked in the low-frequency sub-band derived from the third level transform. To watermark the signature, we save a modified copy of the high energy coefficients of the even part in the odd part. For signature extraction, the watermarked region is partitioned into odd and even columns. The 3-level 3-D is applied to odd and even parts to transform coefficients. The high-energy sub-bands in odd and even parts are separated to extract the signature.Results: Experimental results indicate low degradation of the quality of the watermarked video, along with high robustness of the watermarked video against common attacks in comparison with other tested blind video watermarking methods.Discussion: A comparison of the proposed method with other methods indicates the superior performance of the proposed method in most of the attacks.

In recent years, numerous schemes were proposed that reduce the impact of such attacks. A new method has been proposed to confront cropping attack and salt and pepper noise that is carried out using two Sudoku tables. In this method, the watermark image is scattered in two Sudoku table layouts with different solutions and is watermarked in the host image with Least Significant Bit(LSB). Using this method, the watermark image is repeated 81 times in the host image, and to this effect the watermark image can be reconstructed using other segments when cropped or salt and pepper noise by the attacker. Both Sudokus used in this paper are in the classic 9x9 form and using this method, resistance to cropping attacks increases up to 98.8% and resistance to salt and pepper noise increase up to 80% Manuscript profile -

MoreNumerous methods have been introduced for digital images watermarking as well as rubosting them. In this method, with using Graph-based transform and extracts the best graph structure with genetic algorithm so that watermarking can be performed with maximum robustness. One of the common methods in watermarking robustness is the use of discrete cosine transform (DCT). In this study, we have shown that the proposed method is much more powerful than DCT. The proposed method is tested on five different color images such as Lena, Barbara, Boat, Baboon, Peppers. Watermark image (logo) is a random binary image with size 16 x 16 and 8 x 8 pixels. This simulation results show that the proposed method is more robust to similar methods such as discrete cosine transforms. Proposing Watermarking has been evaluated using Bit Error Rate (BER), Structural Similarity Index Measuring (SSIM) and Peak signal-to-noise ratio (PSNR) criteria and different strength Gaussian noise attacks, JPEG compression, median filter, bluring, rescaling, rotate and cropping attacks Manuscript profile -

In image watermarking, information of the image is inserted such that the visual quality of the image is not reduced and the receiver is able to get the required information. Some attacks such as image cropping, destroy the watermark’s information. In this article, a new watermarking scheme is proposed which is robust against tough cropping. In the proposed scheme, classic Sudoku table which is a 9*9 table, has been used. One feature of Sudoku table is that Sudoku's limitations cause uniform scattering of symbols or numbers throughout the table. In the proposed scheme, Sudoku table and both watermarking approaches based on spatial domain and transform domain such as DCT and DWT are used. Lack of using of soduko solution at the stage of extraction and finding correct solution to obtain watermark, is innovation of this scheme. Robustness of watermarking against cropping attack is up to 92%, which shows good and effective performance of the proposed scheme. Manuscript profile -

In the handling of medical images, the main priority is to secure protection for the patient’s documents against any act of tampering by unauthorized persons. Thus, the main concern of the existing electronic medical system is to develop some standard solution to preserve the authenticity and integrity of the content of medical images.Accordingly, digital image watermarking has many applications, one of its most important applications in Protection of medical images, engrave names, Signatures and Patient data on pictures, Videos etc. that are not so clear.There are several ways to digital image watermarking, but one of the most widely used methods to achieve robust watermarking to all kinds of attacks using the combination dwt and svd.We used in this research 2 level of haar wavelet transform on the host image and one level of single value decomposition on its low frequency subset and combined with a watermark coefficient and another level of singular value decomposition to embed the watermark and increase the watermark robustness in a way that when extracting a watermark can be done semi-blindly. With this method, we were able to improve the average peak signal to noise ratio of 55 and 7% improvement for the invisibility of the watermark and also the average correlation coefficient of 0.97 and 34% improvement to increase the resistance of the watermark to various attacks.
