【文章內(nèi)容簡介】 eople39。s demand on security and techniques mentioned in this article for the mobile phone industry and not a new verification method, but a prehensive analysis of all current methods of verification of a conclusion: when the validation and on which application for is the significance of this paper, I hope you can have a good guide for mobile phone authentication order to ensure the safety based on, as far as possible to make it easier for users to is not only mobile phone industry in the future direction of development, should also be the development trend of all other industries, could therefore be the corresponding reference to the ideas and , multilayer verification In this paper, the concept of multi tier verification is mentioned, that is, to provide different authentication level for different mobile example: for applications such as games and weather can be open to everyone, as long as you get the phone can open these applications, not on the phone owner caused economic losses。for text messages, phone, mail, involves the application of personal privacy, should be set as part of the validation for private, when need to use and need, and for bank accounts and relates to the application of security and property, should give the utmost confidentiality different authentication levels, each user39。s permission to use the phone is not the the mobile phone owner is trusted by the system, it is easy to use all or most of the mobile phone applications in the the first time using a cell phone, the system can not identify their credibility, so only use public mobile application, if you want to open a private or confidential application, you need to other verification the basis of the security of the proposed scheme, it can greatly facilitate the user39。s operation, has gone beyond the original ”Allornothing“ verification , the results of the experiment In this paper, the corresponding experiments are carried basic principle of the experiment is to install a variety of types of sensors on the phone, used to collect a variety of data trusted example: the temperature sensor can collect the user39。s temperature。the sound sensor can be used to collect the user39。s voice gradually when the user calls, the video sensor can collect the user39。s physiological characteristics and so addition, the paper also mentions a new type of verification, which is the verification of the user39。s multiple electronic devices(such as PC, Pad and mobile phones)in the establishment of a Bluetooth connection, when the phone is in use, you can automatically detect the presence of these are connected to the surrounding the system finds that it is unable to connect to other devices, it will improve the security level of the phone, users need to use mobile applications involving privacy, you will need more goal of the experiment is the following four points: 1, reduce the verification cost 2, find the security and convenience of the promise 3, the security of the model to the level of different reasoning logic 4, little energy terms of safety and convenience, the article referred to the FR(Rejection False)and FA(Authentication False)two concepts, that is, the probability of Statistics ”abandon true“ and ”false.FR indicates that a legitimate user is not required to verify the identity of the probability, while FA indicates that an illegal user does not have the probability of being the experiment, the author defines a variable R, when R is higher, indicating that the user needs more high convenience, this will also lead to more FA。when R is low, indicating that users need higher security, which will lead to more experiment proves that the verification technology can meet the needs of users39。 safety and the high level of bank accounts and security requirements of application, ratio of FA always 0 that will never e illegal users not validated using these applications。and fr ratio has been in more than 96%, namely for a legitimate user, with the increase of R, the wrong of the requirements validation probability did not significantly reduced.第三篇：學(xué)術(shù)論文參考南陽師院第十三屆“張衡杯”大學(xué)生課外學(xué)術(shù)科技作品競賽申報(bào)作品一種內(nèi)存數(shù)據(jù)庫快速日志恢復(fù)技術(shù)研究姓 名： * * * 學(xué) 號(hào)： 12345678900 專 業(yè)： 網(wǎng)絡(luò)方向 院 系： 計(jì)算機(jī)與信息技術(shù)學(xué)院 指導(dǎo)老師： * * *摘 要恢復(fù)技術(shù)是保證內(nèi)存數(shù)據(jù)庫運(yùn)行可靠的關(guān)鍵，傳統(tǒng)的基于日志的恢復(fù)技術(shù)會(huì)對(duì)系統(tǒng)性能產(chǎn)生很大的負(fù)面影響。針對(duì)此提出了內(nèi)存數(shù)據(jù)庫系統(tǒng)快速日志恢復(fù)技術(shù)，它控制日志的產(chǎn)生數(shù)量，使得在系統(tǒng)崩潰并重新啟動(dòng)時(shí)，能以最快的速度恢復(fù)到系統(tǒng)崩潰前的最近一致點(diǎn)上。關(guān)鍵字：內(nèi)存數(shù)據(jù)庫；日志恢復(fù)；檢查點(diǎn)Quickly Log Recovery Technology Of MMDBHu Hui hui( of Computer and Information Technolog
