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.

Korean Identification card or driver license is usually used to verify one's identity in Korea. These are also used as an adult certification. Since the form of these ID card is an analog and it needs to be checked with naked eyes, it might be used maliciously. Someone who's got someone else's ID card can do other things. Therefore, it must be reported rapidly when ID card is lost or stolen. The most serious problem might be occurred when they do not recognize and report the loss. They might suffer from pecuniary or mental damage such as opening a mobile phone service, providing loan or credit card, opening a personal checking account, etc. Thus, this study suggests and compares the ways of avoiding these problems. First, the most effective way is to send the authorization code via mobile phones in consideration of build-up period and cost. The person in charge of business processing department using ID card sends the authorization code via registered mobile phone. The owners submits it to the person and their identifications are confirmed. Next effective way is that the person in charge of business processing department using ID card sends text messages via registered mobile phone. Lastly, the most ineffective way is to introduce and implement the electronic ID card ultimately even though it is expensive and takes a long time to build up the system.

The formula contains up between the text and the structural information, as well as their mathematical symbols. Research on-line or off-line recognition formula is underway actively used in various fields, and various forms of the equation are implemented recognition system. Although many documents are included in the various formulas, it is not easy to enter a formula into the computer. Recognition of the expression is divided into two processes of symbol recognition and structural analysis. After analyzing the location information of each character is specified to recognize the effective area after each symbol, and to the structure analysis based on the proximity between the characters is recognized as an independent single formula. Furthermore, analyzing the relationship between the front and back each time a combination of the position relationship between each symbol, and then to add the symbol which was able to easily update the structure of the entire formula. In this paper, by using a scanner to scan the book formula was used to interpret the meaning of the recognized symbol has a relative size and location information of the expression symbol. An algorithm to remove the formulas for calculation of the number of formula is present at the same time is proposed. Using the proposed algorithms to scan the books in the formula in order to evaluate the performance verification as 100% separation and showed the recognition rate equation.
