1226778 玖、發明說明： 【發明所屬之技術領域】 本發明係關於一種具有保密（Data Security)及代理 (Proxy)功能的行動電話與電腦之間同步交換資料之系統， 尤指一種令行動電話與個人電腦之間均可即時獲取對方目 前最新資料，且能達成資料保密，不須裝置SyncML伺服 器即可由網際網路上的SyncML網路代理伺服器執行資料 同步動作之改良式系統。 【先前技術】 個人電腦與可攜式裝置如行動電話是目前消費者用來 儲存通訊錄、行事曆、待辦工作事項、與記事簿等最常使 用的個人運算設備。這兩種設備的普及率非常高，然而， 如何讓這兩種資訊設備上的通訊錄、行事曆等資訊保持同 步更新，一直是困擾消費者的問題。市面上有關於此問題 的解決方案大致分爲兩類：第一類是透過行動電話與個人 電腦的直接連線（實體連接），另一類則是由行動電話經 過無線網路連結到網際網路後，再連結到個人電腦進行同 步動作。 關於前者，係借助於電腦與行動電話之間的直接連線 (利用傳輸線、紅外線、或是無線藍芽）來達到資料交換 的目的。這種同步方式的優點是直接、便利，同時傳送資 料的保密性高也易於取得使用者的信任。然而每次進行同 步資料傳送之際，必須要行動電話、電腦、與傳輸線三者 同時倶備的前提下方能進行，對於只攜帶行動電話出門且 1226778 想要得到即時資料更新的商務人士而言，實屬不便。 至於第二類的解決方案，主要是依循開放行動聯盟 (〇MA，Open Mobile Alliance)所制定的資料同步協定 (SyncML ，相關細節可參考 SyncML 官方網站 http://www.openmobileal 1iance.org/svncml/ ) 〇 在行動 電話上僅須具備SyncML客戶端程式，就可以透過無線網 路傳輸的方式，與SyncML伺服器端做資料同步。這種同 步方式解決了第一種方式的缺點，對於一些只攜帶行動電 §舌出門且想要得到即時資料更新的商務人士而g是一^種極 爲方便的方式，且目前市面上已經有越來越多行動電話可 支援SyncML協定。目前已知的SyncML伺服器都是遵循 SyncML規格書所提及的方式，在HTTP通訊協定埠號80 等待來自SyncML用戶端（可以是行動電話）的連結，然後完 成資料的同步化動作。 惟此種同步方式於實際應用時仍是具有下述缺點： 一、 如果使用者要將行動電話的資料與電腦上的資料 同步更新，那麼勢必要在電腦上架設一 SyncML伺服器。 再者，該SyncML伺服器不僅要能進行資料同步，還必須 能夠抓取電腦上的通訊錄、行事曆之類的資料才行，同時 該SyncML伺服器須要有固定式IP位址。但考量到一般的 家庭或小型辦公室使用者時，可能是透過撥接上網或使用 非固定式IP的固網或ADSL線來上網，因此無法在個人機 器上架設一伺服器。 二、 再者，對於擁有固定IP的個人或是公司而言，即 1226778 使前述難題已加以克服，然而行動電話裡與電腦裡面的資 料傳送方式，係先由行動電話使用整體封包無線服務 (General Packet Radio Service，GPRS)連線，透過電信公司的 WAP閘道器，繞道網際網路（使用HTTP通訊協定），最 後到達SyncML伺服器來做資料同步。在此資料傳送過程 之中，由於HTTP通訊協定是明碼（plain text)傳輸，對 於資料傳輸的私密性無法保證安全無虞，對有心竊取機密 資料的駭客而言，便可利用此漏洞擷取。 【發明內容】 有鑑於現有資料同步更新方式仍存在前述缺點，本發 明之主要目的係提出一種具有保密（Data Security)及代理 (Proxy)功能改良式同步交換資料之系統。可達成使用者無 須架設專屬SyncML伺服器，且以高度資料傳輸安全性進 行同步資料交換的優點。 爲達成前述目的，本發明之同步交換資料系統包含有 一 SyncML網路代理伺服器，內含有受理來自網際網 路之個人電腦資料存取指令，資料庫以供儲存待同步資訊 ，以符合SyncML之通訊協定進行同步資料更新，並與電 信服務業者機房以專屬線路連線的作業機制； 一個人電腦，係內建一行動資訊設計介面程式以及一

路代理伺服器進行資料同步動作，據此與前述個人電腦之 內部資料完成資訊交換； 其中，前述行動電話對SyncML網路代理伺服器之存 取動作係經由專屬線路進行，無繞道網際網路，以避免資 訊曝露而導致的資料攔截。 又’本發明之同步資料交換實施方法係包含有： 第一階段，係於一個人電腦與一 SyncML網路代理伺 服器透過網際網路建立連結，令該個人電腦傳輸待交換資 訊予該SyncML網路代理伺服器，同時查詢該SyncML網路 代理伺服器是否存在可供下載之更新資訊； 第二階段，係於一具有符合資料同步協定（SyncML)之 功能之行動電話與該SyncML網路代理伺服器透過無線通 信方式建立連結，令該行動電話上傳/下載更新資訊予 SyncML網路代理伺服器，據此與前述個人電腦達成資訊交 換。 前述個人電腦更可執行一主動查詢步驟，係主動向該 SyncML網路代理伺服器查詢更新資訊是否已被該行動電話 同步完成，若是，則該個人電腦係再查詢SyncML網路代 理伺服器是否有來自行動電話之更新資訊可供下載。 1226778 又’當前述個人電腦之內部資料變動時，該個人電腦 係可僅單獨傳輸變動部分予SyncML網路代理伺服器。 又，當前述第一階段完成時，SyncML網路代理伺服器 可經由電信服務業者之簡訊中心主動發出一通知簡訊予該 行動電話使用者，令其可以立即進行資料同步。 又，當前述第二階段完成後，前述行動電話與個人電 腦即已達成資料同步，此時內存於SyncML網路代理伺服 器資料庫的同步資料即可允許刪除。如此設計可以節省 SyncML網路代理伺服器資料庫儲存空間，並且個人私密資 料只會短期儲存在外界資料庫中，也加強了資料安全性。 【實施方式】 本發明係針對使用者提出一種具有保密（Data Security) 及代理（Proxy)功能的行動電話與電腦之間同步交換資料之 系統，其應用領域涵蓋個人電腦中的通訊錄、行事曆、待 辦工作事項、記事簿與電子郵件等項目，這些項目均可完 成雙方資料即時更新、交換，其中行動電話係具有符合資 料同步協定（SyncML)之功能，可經由電信服務業者，對符 合SyncML功能的伺服器進行資料同步動作 請參閱第一圖所示，本發明之系統由三大部分組成， 各別爲： 一

)係具有符合資料同步協定 (SyncML)之功能，內部係設計有一人機介面（3 〇 1 )， 可經由電信服務業者，對符合SyncML功能的伺服器進行 資料同步動作。 前述SyncML網路代理伺服器（1 〇 〇 )內含之主伺 服器（1 0 1 )，資料庫伺服器（1 〇 3 )，SyncML同步 更新伺服器（1 0 2 )其實施方式可分別獨立，亦可將此 三種伺服器功能元件合倂裝置在同一硬體設備之中。 於電信服務業者機房（4 0 0 )內則設有一簡訊中心 (4 0 1 )及一無線應用通訊協定（wA P )閘道器（4 0 2)。 由前述架構中可看出本發明其一特徵係在個人電腦（ 20Q)端並無架設一 SyncML伺服器，而是直接藉由網 際網路連上SyncML網路代理伺服器（1 〇 〇 )，以使用 1226778 者的角度而言’即不受個人電腦無固定1 p之限制。 請參閱第一、二圖所不述系統於實際應用時，個 人電腦（2 0 0 )端係先登錄至SyncML網路代理伺服器 (1 〇 0 )，以取得該伺服器之使用權，經認證無誤後， 係向該網路主伺服器（1 〇 1 )查詢於資料庫伺服器（1 03)中是否有來自行動電話（300)之最新資料，若 有資料則將其下載並更新原先儲存的資料。反之，若是無 可供下載之資料，則向SyncML網路代理伺服器（1 〇 〇 )端上傳資料，上傳模式係包含兩種方式：首次上傳資料 時，係將全部的資料傳遞至SyncML網路代理伺服器（1 〇〇），並儲存於該資料庫伺服器（1 0 3 )內；爾後則 採行另一方式，即選擇資料變更的部份上傳即可。資料上 傳之後，網路主伺服器（1 0 1 )可透過簡訊中心（4 0 1 )發出通知訊息，告知行動電話（3 0 0 )端有同步資 料供其下載。 於前述資料上傳/下載過程之中，該行動資訊設計介

data between a mobile phone and a computer having the functions of Data Security and Proxy. The personal computer can obtain the latest information of each other in real time, and it can achieve data confidentiality. The improved SyncML network proxy server on the Internet can perform the data synchronization action without installing a SyncML server. [Prior art] Personal computers and portable devices such as mobile phones are the most commonly used personal computing devices currently used by consumers to store contacts, calendars, to-do tasks, and notebooks. The popularity of these two types of devices is very high. However, how to keep the information such as the address book and calendar on these two types of information devices keep up-to-date has always been a problem for consumers. There are two types of solutions for this problem on the market: the first type is a direct connection (physical connection) to a personal computer through a mobile phone, and the other is a mobile phone connected to the Internet through a wireless network After that, connect to the PC for synchronization. With regard to the former, the direct connection between the computer and the mobile phone (using a transmission line, infrared, or wireless Bluetooth) is used to achieve the purpose of data exchange. The advantage of this synchronization method is that it is direct and convenient. At the same time, the confidentiality of the transmitted data is high and it is easy to gain the user's trust. However, every time you synchronize data transmission, you must do it on the premise of the mobile phone, computer, and transmission line. For business people who only take mobile phones to go out and want to get real-time data updates, It is really inconvenient. As for the second type of solution, it mainly follows the data synchronization agreement (SyncML) formulated by the Open Mobile Alliance (OMA). For details, please refer to the official website of SyncML http: //www.openmobileal 1iance.org/svncml /) 〇Only a SyncML client program is required on the mobile phone to synchronize data with the SyncML server through wireless network transmission. This synchronization method solves the shortcomings of the first method. It is a very convenient way for some business people who only carry mobile phones and want to get real-time data updates, and there are currently more on the market. More and more mobile phones can support the SyncML protocol. The currently known SyncML servers follow the methods mentioned in the SyncML specification, wait for the connection from the SyncML client (which can be a mobile phone) at the HTTP protocol port 80, and then complete the data synchronization operation. However, this synchronization method still has the following disadvantages in practical applications: 1. If the user wants to synchronize the data of the mobile phone with the data on the computer, it is necessary to set up a SyncML server on the computer. In addition, the SyncML server must not only be able to synchronize data, but also be able to capture data such as contacts and calendars on the computer. At the same time, the SyncML server must have a fixed IP address. However, considering ordinary home or small office users, it may be through dial-up or using a fixed IP or ADSL line to access the Internet. Therefore, a server cannot be set up on a personal computer. Second, for individuals or companies with a fixed IP, that is, 1226778, the aforementioned problems have been overcome. However, the data transmission method between the mobile phone and the computer is first used by the mobile phone to use the overall packet wireless service (General Packet Radio Service (GPRS) connection, bypasses the Internet (using the HTTP protocol) through the telecommunications company's WAP gateway, and finally reaches the SyncML server for data synchronization. During this data transmission process, because the HTTP protocol is transmitted in plain text, the privacy of data transmission cannot be guaranteed. For hackers who are interested in stealing confidential data, they can use this vulnerability to capture . [Summary of the Invention] In view of the foregoing shortcomings of the existing data synchronization update method, the main purpose of the present invention is to propose an improved synchronous data exchange system with data security and proxy functions. It can achieve the advantages that users do not need to set up a dedicated SyncML server and perform synchronous data exchange with high data transmission security. In order to achieve the foregoing object, the synchronous exchange data system of the present invention includes a SyncML network proxy server, which contains instructions for receiving personal computer data access from the Internet, and a database for storing information to be synchronized to comply with SyncML communication. Agreement to synchronize data updates, and connect the telecommunications service provider's computer room with a dedicated line; a personal computer, a built-in mobile information design interface program and a client information agent program, the mobile information design interface program is used as a user The operating interface during the actual operation; the client information agent can perform the same 1226778 data upload / download to the SyncML network proxy server through the Internet transmission method; a mobile phone has a data synchronization agreement (SyncML) Function 'and perform a wireless communication method through a human-machine interface, and perform data synchronization action on the SyncML network proxy server through a wireless application communication protocol (WAP) gateway of a telecommunications service provider, and accordingly, the internal communication with the aforementioned personal computer Data complete information exchange; SyncML for mobile phone store to take action line of the web proxy via dedicated line, no bypass Internet, in order to avoid exposure to information resources information resulting from interception. The method of implementing the synchronous data exchange of the present invention includes: The first stage is to establish a connection between a personal computer and a SyncML network proxy server through the Internet, so that the personal computer transmits the information to be exchanged to the SyncML network. Proxy server, while querying whether there is update information available for download in the SyncML network proxy server; the second stage is between a mobile phone with a function that complies with the Data Synchronization Protocol (SyncML) and the SyncML network proxy server Establish a link through wireless communication, so that the mobile phone uploads / downloads the update information to the SyncML network proxy server, and according to this, exchanges information with the aforementioned personal computer. The aforementioned personal computer can also perform an active query step, which is to actively query the SyncML network proxy server whether the update information has been synchronized by the mobile phone. If so, the personal computer then queries whether the SyncML network proxy server has Updates from mobile phones are available for download. 1226778 Also, when the internal data of the aforementioned personal computer changes, the personal computer can transmit only the changed part to the SyncML network proxy server separately. In addition, when the aforementioned first stage is completed, the SyncML network proxy server may actively send a notification message to the mobile phone user via the SMS center of the telecommunications service provider, so that they can immediately synchronize data. In addition, after the aforementioned second stage is completed, the data synchronization between the mobile phone and the personal computer has been achieved. At this time, the synchronized data stored in the database of the SyncML network proxy server can be deleted. This design can save the storage space of the SyncML network proxy server database, and personal private information will only be stored in the external database for a short period of time, which also enhances data security. [Embodiment] The present invention proposes a system for users to synchronize data exchange between a mobile phone and a computer with the functions of Data Security and Proxy, and its application fields include contacts and calendars in personal computers. , To-do items, memo pad and e-mail, etc. These items can complete the real-time update and exchange of data between the two parties. The mobile phone has the function of complying with the data synchronization agreement (SyncML). The function server performs data synchronization. Please refer to the first figure. The system of the present invention is composed of three parts, each of which is: a SyncML network proxy server (100), which contains a network master server. (1 0 1) When receiving data access instructions from a personal computer on the Internet, the database server (103) is used to store the information to be synchronized 'SyncML synchronization update server (1 02) to comply with the SyncML communication 1226778 protocol to synchronize data update and connect with telecommunication service provider's computer room (400) on a dedicated line; (200), which has a mobile information design interface program (201) and a client information agent program (202) built in. The aforementioned mobile information design interface program (201) is actually used as a user. Operation interface when the computer is operating, and the client information agent program (200) belongs to a connection interface program, which can be resident in the personal computer (200), a mobile information design interface program (2 0 1) And the client information agent program (202) can be implemented independently, and the two program function components can also be integrated into the same software; a mobile phone (300) has a data synchronization agreement ( SyncML) function, the interior is designed with a human-machine interface (301), which can be used by telecommunications service providers to synchronize data with servers that comply with the SyncML function. The SyncML network proxy server (100) includes the main server (101), the database server (103), and the SyncML synchronization update server (102). The implementation methods can be independent of each other. You can also combine these three server functional components in the same hardware device. A telecommunication service provider's computer room (400) is provided with a short message center (401) and a wireless application communication protocol (wA P) gateway (402). It can be seen from the foregoing architecture that one of the features of the present invention is that a SyncML server is not set up on the personal computer (20Q) end, but is directly connected to the SyncML network proxy server (100) through the Internet. From the point of view of using 1,226,778, 'that is not subject to the restriction of 1 p for personal computers. Please refer to Figures 1 and 2. When the system is not described in actual application, the personal computer (200) end is first logged into the SyncML network proxy server (100) to obtain the right to use the server. After the authentication is correct, the main server (1001) of the network is asked to check whether there is the latest data from the mobile phone (300) in the database server (103), and if there is data, download it and update the original Stored data. Conversely, if there is no data available for download, upload the data to the SyncML network proxy server (100). The upload mode includes two methods: When the data is uploaded for the first time, all the data is transferred to the SyncML network. The proxy server (100) is stored in the database server (103); then another method is adopted, that is, uploading of the part where the data changes is selected. After the data is uploaded, the network main server (1 0 1) can send a notification message through the SMS center (4 0 1) to inform the mobile phone (3 0 0) that the synchronization data is available for download. During the aforementioned data upload / download process, the mobile information design interface program (201) and the client information agent program (202) exchange data via the Internet and the SyncML network proxy server (100). You can choose to adopt a secure transmission method (such as SSL secure connection mode) to prevent leakage of personal data. As far as the mobile phone (300) is concerned, the human-machine interface (300) is used to pass the wireless application communication protocol (WAP) gateway (400) in the telecommunications service room (400). Connect to the aforementioned SyncML web proxy server (100). In this connection process, 1226778 is first connected to the SyncML synchronization update server (1 0 2) via the gateway (4 0 2), and then the SyncML synchronization update server (1 0 2) is forwarded to the database server (1 0 3) Obtain data such as address book and calendar uploaded from a personal computer (200). And if there is the latest information on the mobile phone (300), the SyncML synchronization update server (102) will also execute the exchange process and record it in the database server (103) for the personal computer (2 0 0) end download. Because the aforementioned SyncML synchronization update server (1 0 2) is connected to the telecommunication service provider's machine room (4 0 0) by a dedicated line, the data transmitted by the mobile phone (3 0 0) is transmitted through the WAP gateway (4 0 2 ), The database server (103) is read directly via the SyncML synchronization update server (102). In the process, no external Internet is used and therefore the code is not exposed, which can prevent the interception of personal information that may occur due to exposure to the Internet. Another function in the aforementioned personal computer (2 0 0) is to perform an active inquiry, which means that the client information agent (2 0 2) will periodically query the network master server (1 0 1) for previously uploaded communications Whether records, calendars and other data have been downloaded and accessed by the mobile phone (300). Once it is known that the data has been accessed, the client information agent (2 0 2) will then ask the network master server (1 0 1) if there is synchronous update data from the mobile phone (3 0 0) , If any, fetch and update actions will be performed. After the synchronization between the personal computer (200) and the mobile phone (300) is completed, the synchronized data stored in the database server (103) at this time can be deleted. 1226778 By performing the aforementioned actions periodically, both ends of the personal computer and mobile phone can obtain the current data of the other party, and during the data transmission process, we also consider the security of the communication to ensure that personal privacy data is not leaked. Data Synchronization: After completion, the data can also be deleted from the SyncML network proxy server to protect the privacy of personal data, and the user's personal computer does not need to set up a dedicated SyncML server, compared to the synchronous update method of conventional data, The present invention does have a significant effect enhancement and meets the requirements of the invention patent 'love law filed.
