In this paper, based on the real estate registration model in the Chinese internet environment, we propose a model for the joint business of banking collateral registration. This is to increase the efficiency and service level of the real estate mortgage registration process. And it can solve the problems that in the process of registering a mortgage loan, difficulty of data sharing between the real estate registration agency and the bank, and ordinary users and bank clerks duplicate unnecessary work. In addition, it realizes joint processing and data sharing of real estate registration work with real estate registration agencies and banks, increases the efficiency and level of government affairs services, and offers an optimized solution to realize a one-stop service for real estate security registration. The results of this study are expected to provide theoretical support for the application and innovation of the Internet environment real estate registration model.

With the development of medical imaging technology, image registration has been widely used in the field of disease diagnosis. The registration between different modal images of brain magnetic resonance (MR) is particularly important for the diagnosis of brain diseases. However, previous registration methods don't take advantage of the prior knowledge of bilateral brain symmetry. Moreover, the difference in gray scale information of different modal images increases the difficulty of registration. In this paper, a multimodal medical image registration method based on image segmentation and symmetric self-similarity is proposed. This method uses modal independent self-similar information and modal consistency information to register images. More particularly, we propose two novel symmetric self-similarity constraint operators to constrain the segmented medical images and convert each modal medical image into a unified modal for multimodal image registration. The experimental results show that the proposed method can effectively reduce the error rate of brain MR multimodal medical image registration with rotation and translation transformations (average 0.43mm and 0.60mm) respectively, whose accuracy is better compared to state-of-the-art image registration methods.

It has become the information medium that mediate between individuals of marketing with the new information media that use of the Internet in accordance with the progress of the IT industry- real estate marketing, real estate leasing, real estate auctions, etc. The real estate registration services should be disclosed to outside that include a schedule details the public book-register and problems caused by it should be reasonably resolved by handling a large amount of real estate registration work quickly, accurately handling to utilize Information Technology(IT) through the information system construction as the feature to process the information of register entries. Computerization of real estate registration will raise the efficiency of the registration as well as people can see the information related to real estate on the basis of published content without limitation the time and place and will pursue the ideal and reliability of the registration -web accessibility improving of the Internet Registry and permanent storage of preserving documents by electronic means. It is very large that impact on the real estate transaction if the accuracy of legal registration choosing formalism in the processing of real estate registration business through the Internet than written application is highly probable to occur incorrect registration. Also, It is necessary to manage it effectively -if you do not quickly and exactly respond to it, there is problems such as delays or poor registration service because real estate business activated and real estate registration services also increased sharply. In this paper, we will identify the problems of the real estate registration work and suggest improvements about it.

The Korean resident registration number has been used since 1962 as a personal identification number. The Korean government assigns this number to each korean citizen and it is not able to be changed. In 2000s, as the Internet was rapidly spreaded out, personal information such as the Korean resident registration number, name, home address, and phone number was leaked. The companies provide diverse internet service while collecting personal information. However, personal information was sometimes leaked because of hacking, poor information management and so on. As s results, some of citizens asked government and court of Korea to change the Korean resident registration number because they suffered material damage and emotional distress. The constitutional court decided to be able to change the number from 2018. In this study, the Korean resident registration number which is possible to change, serial number, public certificate, I-PIN, and My-PIN were analyzed comparatively. In addition, considerations when the Korean resident registration number was changed were discussed. The public certificate and I-PIN were appropriate to the case of on-line Korean resident registration number. The Korean resident registration number, serial number, My-PIN were appropriate to the case of off-line Korean resident registration number. Lastly, it would be efficient to manage the Korean resident registration number separately such as on-line and off-line.

For small image registration, feature-based approaches are likely to fail as feature detectors cannot detect enough feature points from low-resolution images. The classic FFT approach's prediction accuracy is high, but the registration time can be relatively long, about several seconds to register one image pair. To achieve real-time and high-precision rigid registration for small images, we apply deep neural networks for supervised rigid transformation prediction, which directly predicts the transformation parameters. We train deep registration models with rigidly transformed CIFAR-10 images and STL-10 images, and evaluate the generalization ability of deep registration models with transformed CIFAR-10 images, STL-10 images, and randomly generated images. Experimental results show that the deep registration models we propose can achieve comparable accuracy to the classic FFT approach for small CIFAR-10 images (32×32) and our LSTM registration model takes less than 1ms to register one pair of images. For moderate size STL-10 images (96×96), FFT significantly outperforms deep registration models in terms of accuracy but is also considerably slower. Our results suggest that deep registration models have competitive advantages over conventional approaches, at least for small images.

Mobile IP is a solution for mobility on the global Internet. However, it causes service delay incase of frequent movement of mobile node and mobile users. Mobile IP regional registration is Proposed to reduce the service delay. In this paper, we introduce an optimal regional location management mechanism for Mobile IP that reduces the registration delay. The movement of mobile node is described by a discrete analytical model. The proposed model explains analytically average packet rate and registration cost as the size of regional networks with mobility of mobile node.

This paper is proposed a wavelet-based MCDT(Mask Coefficient Differential and Threshold) method of image registration of Multi-images contaminated with visible image and infrared image. The method for ensure reliability of the image registration is to the increase statistical corelation as getting the common feature points between two images. The method of threshold the wavelet coefficients using derivatives of the wavelet coefficients of the detail subbands was proposed to effectively registration images with distortion. And it can define that the edge map. Particularly, in order to increase statistical corelation the method of the normalized mutual information. as similarity measure common feature between two images was selected. The proposed method is totally verified by comparing with the several other multi-image and the proposed image registration.

Personal registration number has been used as a means of personal identification on existing internet. However, its use on internet sites has become a major factor increasing danger of leaking of personal information. Presently, the government recommends i-PIN to minimize the collection of personal registration numbers and leaking of personal information on internet. Original purpose of i-PIN is to recognize persons by its virtual number of 13 digits instead of using personal registration number on internet websites. These days, i-PIN continues to be used increasingly as a form of certification. This study seeks to explore software service methodology of using i-PIN as a form of certification on internet websites and examples in which its other forms of self certification are used than existing i-PIN services.

The personal information extrusion accident(hacking, improper maintenance) by the internet has been increased rapidly during the last ten-year period. The personal information includes Korean resident registration number, name, cellphone number, home telephone number, E-mail address, home address, etc. Korean resident registration number is unchangeable from the cradle to the grave. Illegally accessed personal information can be wrongfully resoled or used at phishing scam. In this paper, we propose a alternative means of Korean resident registration number using the authorized certificate. The authorized certificate is in use safely in Internet. The authorized certificate(included Chinese name) is in used in offline service, the authorized certificate(included English name) is used in online(for government service) and the authorized certificate(not included name) is used in online(for private service). The authorized certificates are possible for discard, republication. The method can reduce the possibility of the personal information extrusion.
