Description
本發明係有關於電腦資源之管理技術,尤其是有關於根據使用者位置控制電腦的技術。The present invention relates to management techniques for computer resources, and more particularly to techniques for controlling a computer based on a user's location.
多人共用一台電腦的使用型態越來越普遍,例如辦公室,學校,網咖等各種公眾場合,即便在家裡也可能是多人共用一台電腦。在多使用者共用電腦的環境下,資源分配問題隨之產生。例如,使用者離開了電腦,電腦卻一直開著,會造成電力浪費的問題。若是有人離開電腦前擅自將電腦鎖定,會影響其他使用者的使用權益,並增加管理者的工作負擔。The use of a computer to share more and more people is becoming more and more common, such as offices, schools, Internet cafes and other public places, even if at home, many people may share a computer. In an environment where multiple users share a computer, resource allocation problems arise. For example, if the user leaves the computer and the computer is always on, it will cause a waste of power. If someone arbitrarily locks the computer before leaving the computer, it will affect the use rights of other users and increase the workload of the administrator.
要解決這類資源分配的問題,傳統的方法包含增加可利用資源,或是限制資源使用條件。像學校電腦教室常用的管理辦法就是使用還原卡,只要進行強迫重開機,原本被佔用的電腦資源就可被還原釋出,以供下一個人使用。然而還原卡並不能解決電力損耗的問題,而且會強制刪除任何更新過的使用者資料。萬一使用者只是短暫離開而不是真的要惡意佔用電腦,強迫重開機的作法反而對使用者造成困擾。To address the problem of such resource allocation, traditional methods include increasing the available resources or limiting resource usage conditions. The management method commonly used in school computer classrooms is to use the restore card. As long as the forced restart is performed, the originally occupied computer resources can be restored and released for the next person to use. However, restoring the card does not solve the problem of power loss, and it will force the deletion of any updated user data. In case the user only leaves for a short time instead of actually maliciously occupying the computer, forcing the reboot is a problem for the user.
另一個問題是當我們在公眾場所使用電腦時總會遇到需要短暫離開電腦的時候,但是我們卻常常忽略要鎖定電腦。這樣的情形常常就會導致我們的電腦(資料)被暴露在危險中。Another problem is that when we use a computer in a public place, we always encounter a need to leave the computer for a short time, but we often ignore the need to lock the computer. Such situations often lead to the exposure of our computers (data) to danger.

When the mobile device enters a certain distance from a certain distance and the computer system is in a non-executive state, the controller sends a second power management signal to the power module through the power control pin to restore the computer system to the power-on or normal state. .
依照本發明又一實施例,提出一種超級輸出輸入模組,用於電腦系統中。超級輸出輸入模組控制電腦系統的序列埠、並列埠、PS/2端子、鍵盤控制模組。超級輸出輸入模組包含無線模組與控制器,此無線模組可用以偵測一行動裝置是否在該電腦系統的特定距離內。控制器電性耦接無線模組,當行動裝置離開特定距離之外,控制器使電腦系統的序列埠、並列埠、PS/2端子、鍵盤控制模組停用(disable);當行動裝置在特定距離內,控制器使該電腦系統的序列埠、並列埠、PS/2端子、鍵盤控制模組恢復正常輸入狀態。According to still another embodiment of the present invention, a super output input module is provided for use in a computer system.

本發明實施例基於「如果使用者在電腦附近,電腦就是安全的;反之就必須特別被加以保護」的概念提出一種控制電腦的方法與裝置。The embodiment of the present invention proposes a method and apparatus for controlling a computer based on the concept that "if the user is in the vicinity of the computer, the computer is safe; otherwise, it must be specially protected."
請參照第1圖,係繪示本發明實施例之一所述之電腦系統架構圖。電腦系統120基本上包含中央處理器102、北橋晶片104、南橋晶片106、主記憶體112以及韌體114等基本單元,各負責不同層次的運作。由於各方面的詳細實作方式隨著技術演進而有許多已知的做法,因此不在本實施例的討論範圍。Please refer to FIG. 1 , which is a structural diagram of a computer system according to an embodiment of the present invention. The computer system 120 basically includes basic units such as a central processing unit 102, a north bridge wafer 104, a south bridge wafer 106, a main memory 112, and a firmware 114, each of which is responsible for different levels of operation. Since the detailed implementation of various aspects has many known practices as the technology evolves, it is beyond the scope of this embodiment.
在本實施例中,電腦系統120可與一行動裝置110進行無線通訊。由於一般使用者會將行動裝置110攜帶在身上,因此可藉行動裝置110來判斷使用者是否處於電腦系統120的附近。電腦系統120中包含一無線模組140,可透過天線130收發無線訊號,與行動裝置110進入無線通訊,以偵測行動裝置110是否在電腦系統120的特定距離內。無線模組140可以是紅外線傳輸模組、一射頻識別模組(RFID)或一藍芽模組,甚至是磁卡感應器。行動裝置110可以是具備憑證資訊的無線裝置,例如藍芽手機、紅外線遙控器、射頻識別卡或磁卡。前述偵測的方式可以是無線模組140主動發出廣播beacon訊號並監聽回音,或是被動的等待行動裝置110發出無線訊號。舉例來說,藍芽就是一種廣播式的通訊協定,而射頻辨識則是一種非接觸式的感應機制。因此各種可能的偵測方式皆可應用在本實施例中。In this embodiment, computer system 120 can communicate wirelessly with a mobile device 110. Since the general user will carry the mobile device 110 on the body, the mobile device 110 can be used to determine whether the user is in the vicinity of the computer system 120. The computer system 120 includes a wireless module 140 that can transmit and receive wireless signals through the antenna 130 and wirelessly communicate with the mobile device 110 to detect whether the mobile device 110 is within a certain distance of the computer system 120. The wireless module 140 can be an infrared transmission module, a radio frequency identification module (RFID) or a Bluetooth module, or even a magnetic card sensor. The mobile device 110 can be a wireless device with credential information, such as a Bluetooth mobile phone, an infrared remote control, a radio frequency identification card, or a magnetic card. The foregoing detection may be performed by the wireless module 140 actively transmitting a broadcast beacon signal and monitoring the echo, or passively waiting for the mobile device 110 to send a wireless signal. For example, Bluetooth is a broadcast communication protocol, and RF identification is a non-contact sensing mechanism. Therefore, various possible detection methods can be applied in this embodiment.
前述無線模組140可更包含驗證器142,行動裝置110中可更包含一憑證(未繪示),此憑證可包含各種用以驗證存取權限的資訊,透過驗證器142驗證行動裝置110中的憑證,可決定行動裝置持有人存取電腦系統120的權限。前述之權限例如可為應用程式的允許/禁止執行權,或是周邊裝置例如鍵盤、滑鼠、光碟機、軟碟機等的允許/禁止使用權。The wireless module 140 may further include a verifier 142. The mobile device 110 may further include a credential (not shown). The credential may include various information for verifying access rights, and the verification device 142 verifies the mobile device 110. The credentials determine the permissions of the mobile device holder to access the computer system 120. The foregoing rights may be, for example, permission/inhibition of the application, or permission/inhibition of peripheral devices such as a keyboard, a mouse, a CD player, a floppy disk drive, and the like.
請參考圖1,在本實施例中電腦系統可包含一整合晶片如超級輸入輸出模組(Super I/O)108。超級輸入輸出模組108電性耦接無線模組140、南橋晶片106與電源模組116。更具體而言,超級輸入輸出模組108中可更包含一控制器150,無線模組140可整合至超級輸入輸出模組108中做為超級輸入輸出模組108的一個子單元。透過電性耦接無線模組140或將無線模組140-整合至超級輸入輸出模組108,超級輸入輸出模組108可依據無線模組140的偵測結果控制電腦系統120的狀態。在本發明另一實施例中,超級輸入輸出模組108亦可更包含韌體152,韌體152電性耦接控制器150。前述韌體152可用以協助控制器150改變電腦系統120的狀態。Referring to FIG. 1, in the embodiment, the computer system may include an integrated chip such as a Super I/O module 108. The super input/output module 108 is electrically coupled to the wireless module 140, the south bridge chip 106, and the power module 116. More specifically, the super input/output module 108 can further include a controller 150. The wireless module 140 can be integrated into the super input/output module 108 as a subunit of the super input/output module 108. By electrically coupling the wireless module 140 or integrating the wireless module 140- into the super input/output module 108, the super input/output module 108 can control the state of the computer system 120 according to the detection result of the wireless module 140. In another embodiment of the present invention, the super input/output module 108 may further include a firmware 152, and the firmware 152 is electrically coupled to the controller 150. The aforementioned firmware 152 can be used to assist the controller 150 in changing the state of the computer system 120.
舉例來說,當行動裝置110位於電腦系統120特定距離之外時,超級輸入輸出模組108將發出第一管理訊號,使電腦系統120進入一非執行狀態。當行動裝置110從特定距離之外進入特定距離之內時,且電腦系統120處於非執行狀態,超級輸入輸出模組108發出一第二管理訊號,使該電腦系統回復至開機或正常狀態。前述之非執行狀態例如可為休眠狀態、待命狀態或關機狀態。For example, when the mobile device 110 is outside a certain distance of the computer system 120, the super input/output module 108 will issue a first management signal to cause the computer system 120 to enter a non-executive state. When the mobile device 110 enters a certain distance from a certain distance, and the computer system 120 is in a non-executive state, the super input/output module 108 sends a second management signal to return the computer system to the power on or normal state. The aforementioned non-execution state may be, for example, a sleep state, a standby state, or a shutdown state.
在本發明一實施例中,此第一管理訊號與第二管理訊號分別為第一電源管理訊號與第二電源管理訊號。超級輸入輸出模組108透過其電源控制腳位118傳送第一或第二電源管理訊號#PWR至電源模組116,此電源模組116電性耦接電源控制腳位118。前述電源控制腳位118可為先進技術擴展(ATX)電源規範的PS-ON腳位。根據先進技術擴展(ATX)電源規範,電源模組116可受到特定的訊號控制,例如PS-ON,以控制電腦系統120的電源狀態。在此實施例中,超級輸入輸出模組108可透過其控制器150發出第一或第二電源管理訊號#PWR至電源模組116。此外,亦可透過韌體152協助控制器150的方式,使電腦系統120進入非執行狀態,或使電腦系統120回復至開機或正常狀態。In an embodiment of the invention, the first management signal and the second management signal are a first power management signal and a second power management signal, respectively. The super input/output module 108 transmits the first or second power management signal #PWR to the power module 116 through its power control pin 118. The power module 116 is electrically coupled to the power control pin 118. The aforementioned power control pin 118 can be the PS-ON pin of the Advanced Technology Extension (ATX) power specification. According to the Advanced Technology Extension (ATX) power supply specification, the power module 116 can be controlled by a specific signal, such as PS-ON, to control the power state of the computer system 120. In this embodiment, the super input/output module 108 can send the first or second power management signal #PWR to the power module 116 through its controller 150. In addition, the computer system 120 can be brought into a non-executive state by the firmware 152 to assist the controller 150, or the computer system 120 can be returned to the power-on or normal state.
前述之超級輸入輸出模組108可不受作業系統及軟體的控制而獨立運作。例如在電腦系統120關機時,電腦系統120中的中央處理器102,南橋晶片106及北橋晶片104可能因關機而停止運作,但是該超級輸入輸出模組108仍然可保持在運作狀態,持續偵測外界行動裝置110的存在與否。當行動裝置110從特定距離之外進入特定距離之內時,超級輸入輸出模組108可透過其控制器150發出第一或第二電源管理訊號#PWR至電源模組116,使電腦系統120進入開機狀態。The aforementioned super input/output module 108 can operate independently from the control of the operating system and the software. For example, when the computer system 120 is turned off, the central processing unit 102, the south bridge chip 106, and the north bridge chip 104 in the computer system 120 may be stopped due to shutdown, but the super input/output module 108 can remain in operation and continuously detected. The presence or absence of the external mobile device 110. When the mobile device 110 enters a certain distance from a certain distance, the super input/output module 108 can send the first or second power management signal #PWR to the power module 116 through its controller 150 to cause the computer system 120 to enter. Power on state.
在本發明另一實施例中,超級輸入輸出模組108所發出的第一管理訊號或第二管理訊號可透過南橋晶片106傳送至中央處理器102中。透過搭配驅動程式(未繪示),中央處理器102可依據前述第一或第二管理訊號之內容轉換電腦系統120之狀態(例如由非執行狀態轉換為開機或正常狀態,或由正常狀態轉換為非執行狀態)。In another embodiment of the present invention, the first management signal or the second management signal sent by the super input/output module 108 can be transmitted to the central processing unit 102 through the south bridge chip 106. Through the matching driver (not shown), the central processing unit 102 can convert the state of the computer system 120 according to the content of the first or second management signal (for example, from a non-executive state to a power-on or normal state, or from a normal state transition). Is not in the execution state).
在本發明另一實施例中,超級輸入輸出模組108可透過一低腳位數(LPC)或序列周邊介面(Serial Peripheral Interface Bus,SPI)連接南橋晶片106及韌體114。韌體114例如可為基本輸出輸入系統(Basic Input/Output system;BIOS)。搭配韌體114,超級輸入輸出模組108亦可透過第一或第二管理訊號,變更電腦系統120的狀態。In another embodiment of the present invention, the super input/output module 108 can connect the south bridge wafer 106 and the firmware 114 through a low pin number (LPC) or a Serial Peripheral Interface Bus (SPI). The firmware 114 can be, for example, a Basic Input/Output system (BIOS). With the firmware 114, the super input/output module 108 can also change the state of the computer system 120 through the first or second management signal.
為更詳細說明本發明,特舉下列實施例來做進一步說明。前述無線模組140可持續與行動裝置110進行通訊,若無線模組140原本偵測得到行動裝置110,後來偵測不到行動裝置110,則可判斷行動裝置110正從有效距離之內往外遠離。藉此,超級輸入輸出模組108發出管理訊號(例如電源管理訊號#PWR)至電源模組116,觸發後續相關的先進架構電源界面(ACPI)機制,使整個電腦系統120進入一種非執行狀態。假設無線通訊的有效距離是10公尺,則表示使用者只要在電腦系統120周圍10公尺之內,即可繼續保持電腦系統120的使用狀態。在有效距離之內,也可以定義更嚴謹的判斷標準,例如判斷行動裝置110離開電腦系統120一公尺或兩公尺以上就視為離開。In order to explain the present invention in more detail, the following examples are further illustrated. The wireless module 140 can continuously communicate with the mobile device 110. If the wireless module 140 originally detects the mobile device 110 and then does not detect the mobile device 110, it can be determined that the mobile device 110 is moving away from the effective distance. . Thereby, the super input/output module 108 sends a management signal (for example, power management signal #PWR) to the power module 116, triggering a subsequent related advanced architecture power interface (ACPI) mechanism, so that the entire computer system 120 enters a non-executive state. Assuming that the effective distance of the wireless communication is 10 meters, it means that the user can continue to use the computer system 120 as long as it is within 10 meters of the computer system 120. Within the effective distance, more stringent criteria can also be defined. For example, it is determined that the mobile device 110 is away from the computer system 120 by one meter or more.
相對的,如果無線模組140原本偵測不到行動裝置110,後來偵測到了行動裝置110,則可判斷行動裝置110正從遠處進入有效距離之內。此時如果電腦系統120正處於非執行狀態(例如關機狀態),則超級輸入輸出模組可再次透過電源管理訊號#PWR通知電源模組114,觸發後續相關的ACPI機制使電腦系統120回復至開機。當然,電腦系統亦可透過搭配作業系統、驅動程式或韌體來定義電源控制腳位例如PS-ON被觸發時應要進行休眠、待命還是關機。因此相關的應用方式可以視需要而有各種變化,在此不加贅述。In contrast, if the wireless module 140 does not detect the mobile device 110 and then detects the mobile device 110, it can be determined that the mobile device 110 is entering the effective distance from a distance. At this time, if the computer system 120 is in a non-executive state (for example, a shutdown state), the super input/output module can notify the power module 114 through the power management signal #PWR again, triggering the subsequent related ACPI mechanism to cause the computer system 120 to return to the boot. . Of course, the computer system can also define the power control pin by matching the operating system, driver or firmware. For example, when PS-ON is triggered, it should be dormant, standby or shut down. Therefore, the related application manners can be variously changed as needed, and will not be described herein.
當然,如上述實施例所述,超級輸入輸出模組108亦可將管理訊號傳送至中央處理器102以改變電腦系統120的狀態,在此不再贅述。Of course, as described in the foregoing embodiment, the super input/output module 108 can also transmit the management signal to the central processing unit 102 to change the state of the computer system 120, and details are not described herein again.
透過本發明上述實施例所述之超級輸入輸出模組108與無線模組140,電腦系統120可直接由例如關機狀態恢復到例如開機狀態,或在例如開機狀態變更為例如關機狀態。此外,透過無線模組140驗證行動裝置110的憑證有效性,可提供更進階的安全控管。例如輸出輸入模組108可依據驗證器142之驗證結果決定行動裝置110持有人存取電腦系統的權限(例如允許執行的應用程式與禁止執行的應用程式),亦或是當憑證驗證失敗時,超級輸入輸出模組108中的控制器150將不發出例如電源管理訊號#PWR至電源模組。除此之外,憑證亦可在多人使用電腦的公共場合提供辨識功能(例如某一憑證僅能對應到某一電腦)。Through the super input/output module 108 and the wireless module 140 described in the above embodiments of the present invention, the computer system 120 can be directly restored from, for example, a shutdown state to, for example, a power-on state, or changed to, for example, a power-off state, for example, a power-off state. In addition, verifying the validity of the credentials of the mobile device 110 via the wireless module 140 provides for more advanced security controls. For example, the output input module 108 can determine the permission of the mobile device 110 to access the computer system according to the verification result of the verification device 142 (for example, an application that is allowed to be executed and an application that is prohibited from executing), or when the verification of the certificate fails. The controller 150 in the super input/output module 108 will not issue, for example, the power management signal #PWR to the power module. In addition, the voucher can also provide identification in public places where multiple people use the computer (for example, a voucher can only correspond to a certain computer).
請再參考第1圖,超級輸入輸出模組108基本上專門控制傳統的PS/2端子、序列埠、並列埠、遊戲埠、軟碟埠、鍵盤控制模組等周邊裝置。在本發明另一實施例中,超級輸入輸出模組108同樣可依據前述之無線模組140偵測行動裝置110之結果,對這些週邊裝置中的部份或全部進行權限控制。例如,當行動裝置110離開無線模組140特定距離之外時,超級輸入輸出模組108中的控制器150可使前述PS/2端子、序列埠、並列埠、鍵盤控制模組等資料輸入輸出裝置停用(disable)。當行動裝置110在無線模組140特定距離之內-時,控制器150可使前述PS/2端子、序列埠、並列埠、鍵盤控制模組等資料輸入輸出裝置恢復正常狀態。在前述資料輸入輸出裝置停用時,電腦系統120可繼續輸出畫面或聲音。這種狀態尤其適合在展場公開展示電腦或是簡報的場合,可有效避免不特定的使用者接觸並操控電腦系統120。當然,如上述其他實施例所述,無線模組140同樣可整合至超級輸入輸出模組108中,在此不再贅述。Referring again to FIG. 1, the super input/output module 108 basically controls the peripheral devices such as the conventional PS/2 terminal, the serial port, the parallel port, the game console, the floppy disk, and the keyboard control module. In another embodiment of the present invention, the super input/output module 108 can also perform permission control on some or all of the peripheral devices according to the result of detecting the mobile device 110 by the wireless module 140. For example, when the mobile device 110 is away from the wireless module 140 by a certain distance, the controller 150 in the super input/output module 108 can input and output data such as the PS/2 terminal, the serial port, the parallel port, the keyboard control module, and the like. The device is disabled. When the mobile device 110 is within a certain distance of the wireless module 140, the controller 150 can restore the data input/output device such as the PS/2 terminal, the serial port, the parallel port, and the keyboard control module to a normal state. When the aforementioned data input/output device is deactivated, the computer system 120 can continue to output a picture or sound. This state is especially suitable for occasions where the computer or presentation is publicly displayed on the exhibition site, which can effectively prevent the unspecified user from contacting and manipulating the computer system 120. Of course, the wireless module 140 can be integrated into the super input/output module 108 as described in other embodiments, and details are not described herein.
此外,由於輸入輸出模組108控制了前述鍵盤與滑鼠等資料輸入輸出裝置,因此可進一步利用此特性來變化本發明前述實施例之態樣。例如,當行動裝置110從遠處進入特定距離之內時,則超級輸入輸出模組可透過鍵盤控制模組(未繪示)發出一串模擬鍵盤輸入,使電腦系統120由非執行狀態恢復到正常狀態,或是使電腦系統120認為收到了使用者敲打的密碼指令,進而使螢幕鎖定狀態自動解除。前述之鍵盤控制模組可直接電性耦接無線模組140,以依據無線模組140的偵測結果進行反應。模擬鍵盤輸入可以是事先設定好而儲存在韌體114中的一組解鎖定密碼。In addition, since the input/output module 108 controls the aforementioned data input/output devices such as a keyboard and a mouse, this characteristic can be further utilized to change the aspect of the foregoing embodiment of the present invention. For example, when the mobile device 110 enters a certain distance from a distance, the super input/output module can issue a series of analog keyboard inputs through a keyboard control module (not shown), so that the computer system 120 is restored from the non-executed state to The normal state, or the computer system 120 believes that the password command received by the user is received, so that the screen lock state is automatically released. The foregoing keyboard control module can be directly coupled to the wireless module 140 to react according to the detection result of the wireless module 140. The analog keyboard input can be a set of unlocked passwords stored in firmware 114 that are previously set.
上述的各種應用可以組合在一起實施。舉例來說,當行動裝置110離開一有效範圍之外時,電腦系統120並不馬上待命或關機,而是先進入一螢幕鎖定狀態或是登出作業系統。當螢幕鎖定狀態或登出狀態持續一段時間沒有回復時,超級輸入輸出模組才發出電源管理訊號#PWR使電腦系統120進一步進入休眠狀態、待命狀態或關機狀態。The various applications described above can be implemented in combination. For example, when the mobile device 110 leaves an effective range, the computer system 120 does not immediately stand by or shut down, but first enters a screen lock state or logs out of the operating system. When the screen lock state or the logout state does not reply for a period of time, the super input/output module issues the power management signal #PWR to cause the computer system 120 to further enter the sleep state, the standby state, or the shutdown state.
上述實施例可以整理成一個流程圖,如第2圖所示。在步驟201中,啟動電腦系統120。在步驟203中,由無線模組140偵測行動裝置110是否位在電腦系統120的附近。只要無線模組140感測不到行動裝置110,或是判斷行動裝置110的距離超出一特定範圍,就進行步驟205,將電腦系統120切換至非執行狀態。在此所謂的非執行狀態泛指限制使用者正常操作電腦系統120的各種狀態,包含螢幕鎖定、登出、待機或關機等。若是在步驟203中感測到行動裝置110,而且其中的憑證也被識別出具合法的權限,則進行步驟207,將電腦系統120從非執行狀態中還原至正常狀態。若是步驟203中感測到下一使用者與上一使用者為不同人,則步驟207中的回復正常狀態之步驟必須至少包含將上一使用者登出,以避免個人資料外洩。The above embodiment can be organized into a flow chart as shown in Fig. 2. In step 201, computer system 120 is booted. In step 203, the wireless module 140 detects whether the mobile device 110 is located in the vicinity of the computer system 120. As long as the wireless module 140 does not sense the mobile device 110 or determines that the distance of the mobile device 110 exceeds a certain range, step 205 is performed to switch the computer system 120 to the non-executing state. The so-called non-executive state herein generally refers to restricting various states of the user's normal operation of the computer system 120, including screen lock, logout, standby, or shutdown. If the mobile device 110 is sensed in step 203 and the credentials therein are also identified as having legitimate rights, then step 207 is performed to restore the computer system 120 from the non-executing state to the normal state. If it is detected in step 203 that the next user and the previous user are different, the step of returning to the normal state in step 207 must include at least logging out the previous user to avoid leakage of personal data.
雖然本發明以實施例說明如上,但可以理解的是本發明的範圍未必如此限定。相對的,任何基於相同精神或對本發明所屬技術領域中具有通常知識者為顯而易見的改良皆在本發明涵蓋範圍內。因此專利要求範圍必須以最廣義的方式解讀。Although the present invention has been described above by way of examples, it is to be understood that the scope of the invention is not necessarily limited. In contrast, any modifications that are obvious to those of ordinary skill in the art to which the invention pertains. Therefore, the scope of patent claims must be interpreted in the broadest sense.
