Preferably, the server further processes the user's access credentials for the door unlocking process.
Alternately, the controller couples with an electronic door system and sensors for controlling the operation of the door.
Preferably, the controller tracks and reports door status to the server.
Preferably, the mobile device application receives user's access credentials from the server to perform local authentication.
Alternately, the biometric data collecting means is in the form of fingerprint sensor, face recognition sensor, iris sensor, body posture sensor or in any combination thereof.
One skilled in the art will readily appreciate that the invention is well adapted to carry out the objects and obtain the ends and advantages mentioned, as well as those inherent therein. The embodiments described herein are not intended as limitations on the scope of the invention.
For the purpose of facilitating an understanding of the invention, there is illustrated in the accompanying drawing the preferred embodiments from an inspection of which when considered in connection with the following description, the invention, its construction and operation and many of its advantages would be readily understood and appreciated.
The invention will now be described in greater detail, by way of example, with reference to the drawings.
Preferably, the mobile device 160 includes a display unit, biometric sensors and a transceiver. The mobile application downloads user's access credential data from cloud base server 110, wherein the user's access credential data includes user's authentication data, user's door entrance accessibility, and accessible date and time. The application further processes the data and reflects the doors allow to access on handheld device's display unit to alert the user. The application installed on the handheld device 160 allows the user to send user ID, date, time and controller 140 pairing code to the controller 140 via BLUETOOTH connection 150. The controller 140 validates the data by internal memory (current date, time and user ID) as second security layer. The controller 140 then sends signal to unlock door when data is validated. All the entry-exit records will be sent to the cloud base server 110 by the controller 140 via internet connection. Preferably, the controller 140 is connected to a network router or modem 130 for internet accessibility with the cloud base server 110.
The system 100 operations in different embodiment of operation. One of the embodiment discloses the administrator operation as shown in
Another embodiment of the system 100 as illustrated in
On the other hand, the BLUETOOTH access controller 140 broadcasts its device ID via BLUETOOTH link 150 to the mobile device 160 such that the users are no longer required to activate the application in the mobile device before approaching the BLUETOOTH access controller 140. When a user with the mobile device 160 comes into the broadcasting range, the application captures the device ID and starts to compute the accessibility. The computing process can be referred in step 303 of
Furthermore, the BLUETOOTH access controller also includes security feature as shown in
On the other hand, the use of second layer of authentication in the controller 140, where the controller 140 performs checking on the user ID, date and time before the door access could be granted had minor the possibility of hijacking. In case system administrator restrict the user to access any door, but the user does not update the data in his mobile device 160. However, the changes already applied to all controllers 140, by removing the selected user ID to block access. This stops the user to access even his application in mobile device grant him access. When comes to access time control, user can change date and time of the mobile device 160. Thus, the controller 140 validates the date and time sent by the application in mobile device 160, to ensure time is synced.
