In addition, in the process of transferring the physiological data, the traditional smart care system usually uses DES encryption method for encryption to ensure the security of data transmission. However, although the encryption processing speed of DES is very fast, its security is still slightly insufficient, resulting in the traditional smart care system being easily invaded by hackers. Moreover, the time for the intelligent care system to obtain the physiological data must also be a valid time value, so that the physiological data has reference value.

因此，如何設計一個資訊安全強度較佳的智能照護系統，且該智能照護系統所取得的生理數據還具備有效的時間值，便是本領域具有通常知識者值得去思量地。 Therefore, how to design an intelligent care system with better information security strength, and the physiological data obtained by the intelligent care system also has an effective time value, is worth considering for those with ordinary knowledge in the field.

圖3所繪示為第二時間戳記、生理數據資料及加密金鑰。 Figure 3 shows the second time stamp, physiological data and encryption key.

請參閱圖1，圖1所繪示為本實施例之智能照護系統10通訊連接可攜式電子裝置7的示意圖。智能照護系統10包括至少一生理值偵測裝置12、一主伺服器13、一雲端伺服器14及一時間同步裝置15。其中，主伺服器13是通訊連接生理值偵測裝置12及雲端伺服器14，而時間同步裝置15是通訊連接主伺服器13及雲端伺服器14。生理值偵測裝置12是用於量測一被測者的生理值(請參閱圖2，圖2所繪示為生理值偵測裝置12位於該被測者的手腕或腹部的示意圖)，以產生一生理數據資料12D。詳細來說，該被測者通常為長輩或是嬰幼兒。當該被測者為長輩時，生理值偵測裝置12是適合穿戴於長輩的手腕上，而對於0~6個月的嬰兒，生理值偵測裝置12則是適用於穿戴於嬰兒的腹部上。另外，該生 理值例如為被測者的體溫值、心跳值、血壓值或血糖值(本實施例是以該被測者的體溫值作為範例)，所以生理數據資料12D便是記錄著該被測者的體溫值、心跳值、血壓值或是血糖值。此外，生理值偵測裝置12包括一訊號傳輸模組121，訊號傳輸模組12例如為藍芽通訊模組或Wi-Fi模組，訊號傳輸模組121主要是用以傳送生理數據資料12D至主伺服器13。在圖1中，智能照護系統10是只使用一個生理值偵測裝置12作為範例。然而，智能照護系統10也能具有多個生理值偵測裝置12，便能取得不同被測者的生理數據資料12D。 Please refer to FIG. 1, which is a schematic diagram of the smart care system 10 of this embodiment being connected to a portable electronic device 7 in communication. The smart care system 10 includes at least one physiological value detecting device 12, a main server 13, a cloud server 14 and a time synchronization device 15. The main server 13 is in communication with the physiological value detecting device 12 and the cloud server 14, and the time synchronization device 15 is in communication with the main server 13 and the cloud server 14. The physiological value detecting device 12 is used to measure the physiological value of a subject (please refer to FIG. 2, which is a schematic diagram of the physiological value detecting device 12 located on the wrist or abdomen of the subject), Generate a physiological data 12D. In detail, the subject is usually an elder or infant. When the subject is an elder, the physiological value detecting device 12 is suitable for being worn on the wrist of the elder, and for a baby from 0 to 6 months old, the physiological value detecting device 12 is suitable for being worn on the baby's abdomen . In addition, the student The physical value is, for example, the subject’s body temperature, heartbeat, blood pressure, or blood glucose value (this embodiment takes the subject’s body temperature as an example), so the physiological data 12D records the subject’s Body temperature, heartbeat, blood pressure, or blood sugar. In addition, the physiological value detecting device 12 includes a signal transmission module 121. The signal transmission module 12 is, for example, a Bluetooth communication module or a Wi-Fi module. The signal transmission module 121 is mainly used to transmit physiological data 12D to Main server 13. In FIG. 1, the smart care system 10 uses only one physiological value detecting device 12 as an example. However, the smart care system 10 can also have a plurality of physiological value detecting devices 12 so as to obtain the physiological data 12D of different subjects.

請再次參閱圖1，當主伺服器13接收到生理數據資料12D時，主伺服器13會依據接收到生理數據資料12D的時間形成一第一時間戳記13A。此外，主伺服器13包括一加密模組131，加密模組131是用以對生理數據資料12D進行加密，其加密的方式詳細說明如下： Please refer to FIG. 1 again. When the main server 13 receives the physiological data 12D, the main server 13 will form a first time stamp 13A according to the time when the physiological data 12D is received. In addition, the main server 13 includes an encryption module 131. The encryption module 131 is used to encrypt the physiological data 12D. The encryption method is described in detail as follows:

當形成第一時間戳記13A之後，加密模組131會立即發送一觸發訊號131S至雲端伺服器14內。並且，主伺服器13還會依據觸發訊號所發出的時間形成一個第二時間戳記13B。之後，加密模組131會以第二時間戳記13B的部分作為一加密金鑰131E對生理數據資料12D進行加密，以形成一個已加密生理數據資料131D。其中，加密金鑰131E是依照8位元(64bits)的長度編號，加密金鑰131E包括第二時間戳記13B的分鐘部分(2bytes)，秒鐘部分(2bytes)直到10-2，並添加入“00”(2bytes)，例如圖3中的「Mainkey：57582000」(請參閱圖3，圖3所繪示為第二時間戳記、生理數據資料及加密金鑰)。如此一來，隨著第二時間戳記13B的隨機性及難以捉摸的特性，也會產生無法預判的加密金鑰131E，故已加密生理數據資料131D具有極高的安全強度。 After the first time stamp 13A is formed, the encryption module 131 will immediately send a trigger signal 131S to the cloud server 14. In addition, the main server 13 also forms a second time stamp 13B according to the time when the trigger signal is sent. After that, the encryption module 131 uses the part of the second time stamp 13B as an encryption key 131E to encrypt the physiological data data 12D to form an encrypted physiological data data 131D. Among them, the encryption key 131E is numbered according to the length of 8 bits (64bits). The encryption key 131E includes the minute part (2bytes) and the second part (2bytes) of the second time stamp 13B up to 10 -2 , and adds "00" (2bytes), such as "Mainkey: 57582000" in FIG. 3 (please refer to FIG. 3, which shows the second time stamp, physiological data, and encryption key). In this way, with the randomness and elusive characteristics of the second time stamp 13B, an unpredictable encryption key 131E will also be generated, so the encrypted physiological data data 131D has extremely high security strength.

此外，時間同步裝置15例如為一GPS衛星或一時間母鐘，其主要是用以同步主伺服器13與雲端伺服器14的時間。並且，時間同步裝置15是依據PTP協 定或NTP協定來校正主伺服器13的時間及雲端伺服器14的時間，所以兩者的時間能達到高精度的同步。 In addition, the time synchronization device 15 is, for example, a GPS satellite or a time master clock, which is mainly used to synchronize the time of the main server 13 and the cloud server 14. Also, the time synchronization device 15 is based on the PTP protocol The time of the main server 13 and the time of the cloud server 14 can be adjusted according to the NTP protocol, so the time of the two can be synchronized with high precision.

另外，雲端伺服器14除了接收觸發訊號131S之外，雲端伺服器14還用以接收已加密生理數據資料131D及第一時間戳記13A。其中，第一時間戳記13A的時間便是代表取得生理數據資料12D的一個有效的時間值。此外，雲端伺服器14包括一解密模組141，解密模組141對已加密生理數據資料進行解密，其解密的方式詳細說明如下： In addition, in addition to receiving the trigger signal 131S, the cloud server 14 is also used to receive the encrypted physiological data data 131D and the first time stamp 13A. Among them, the time of the first time stamp 13A represents a valid time value for obtaining the physiological data 12D. In addition, the cloud server 14 includes a decryption module 141. The decryption module 141 decrypts the encrypted physiological data. The decryption method is described in detail as follows:

當雲端伺服器14接收到觸發訊號131S時，雲端伺服器14會依據接收到觸發訊號131S的時間形成一第三時間戳記14B。其中，由於雲端伺服器14的時間是同步於主伺服器13的時間，且加密模組131發出觸發訊號131S的時間幾乎是相同於雲端伺服器1接收到觸發訊號131S時間，所以第二時間戳記13B的部分會相同於第三時間戳記14B的部分。因此，解密模組能以第三時間戳記14B的部分作為一解密金鑰對已加密生理數據資料131D進行解密，以形成已解密生理數據資料141D。由於本系統是利用時間戳記作為加密及解密的金鑰，所以外部駭客的強力攻擊也不易破解本系統的已加密生理數據資料131D。因此，該被測者的生理數據資料12D在傳送的過程中具有更高的機密性，還能確保資料的正確性和完整性。 When the cloud server 14 receives the trigger signal 131S, the cloud server 14 will form a third time stamp 14B according to the time when the trigger signal 131S is received. Among them, since the time of the cloud server 14 is synchronized with the time of the main server 13, and the time when the encryption module 131 sends the trigger signal 131S is almost the same as the time when the cloud server 1 receives the trigger signal 131S, the second time stamp is The part of 13B will be the same as the part of the third time stamp 14B. Therefore, the decryption module can use the part of the third time stamp 14B as a decryption key to decrypt the encrypted physiological data 131D to form the decrypted physiological data 141D. Since the system uses the time stamp as the key for encryption and decryption, it is not easy to crack the encrypted physiological data 131D of the system by a powerful attack by an external hacker. Therefore, the physiological data 12D of the subject has higher confidentiality during the transmission process, and the accuracy and integrity of the data can also be ensured.

本系統是經由雲端伺服器14通訊連接外部的可攜式電子裝置7，可攜式電子裝置7例如為智慧型手機、智慧型手錶、平板電腦或筆記型電腦，且可攜式電子裝置7通常為該被測者的相關親屬所持有。之後，雲端伺服器14會將已解密生理數據資料141D及第一時間戳記13A傳送至可攜式電子裝置7內。這樣一來，可攜式電子裝置7的持有者便能在第一時間得知該被測者的生理數據資料12D及取得生理數據資料12D的正確時間。因此，當該被測者的生理數 據資料12D有異常狀態發生時，該被測者的相關親屬能立即警示或到場了解情況。 This system communicates with an external portable electronic device 7 via a cloud server 14. The portable electronic device 7 is, for example, a smart phone, a smart watch, a tablet computer or a notebook computer, and the portable electronic device 7 is usually Held by relatives of the subject. After that, the cloud server 14 sends the decrypted physiological data 141D and the first time stamp 13A to the portable electronic device 7. In this way, the holder of the portable electronic device 7 can know the physiological data 12D of the subject and the correct time to obtain the physiological data 12D at the first time. Therefore, when the subject’s physiological number According to data 12D, when an abnormal state occurs, the relatives of the subject can immediately warn or come to the scene to understand the situation.

雖然本發明已以較佳實施例揭露如上，然其並非用以限定本發明，任何所屬技術領域中具有通常知識者，在不脫離本發明之精神和範圍內，當可作些許之更動與潤飾，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。 Although the present invention has been disclosed as above in preferred embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the relevant technical field can make some changes and modifications without departing from the spirit and scope of the present invention.
