Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a tamper resistant key mouse input monitoring system, comprising: the system comprises a keyboard, a mouse, a storage module, an information acquisition module and a client, wherein the mouse and the keyboard are connected to the client; the information acquisition module acquires the input operation of the keyboard and the time of the input operation, and the time of the mouse click, the roller operation and the operation; the mouse and the keyboard share a clock module and provide the time sequence signal; the operation and operation time storage value acquired by the information acquisition module is transmitted to a server; the client acquires the operation and operation time of all mouse and keyboard input signals connected to the client and uploads the operation and operation time to the server; the server compares the operation and operation time of the keyboard and the mouse acquired by the keyboard and the mouse and the client module respectively, calculates the matching degree of the two parties, and sets a matching degree threshold, for example, the threshold may be set to be 1%. When the matching degree is lower than the threshold value, the server displays an alarm, so that the aim of rapidly detecting cheating of the external keyboard and mouse is fulfilled.
More specifically, a microphone is arranged on the server, a loudspeaker is arranged on the client, and the microphone is connected with the loudspeaker through a signal, so that a prisoner can call a designated examinee through the server.
In addition, the invention also comprises a monitoring module, wherein the monitoring module comprises a plurality of cameras; the pictures collected by the monitoring module at least comprise: a picture of the face of the examinee and the keyboard in the same frame, and a picture of the face of the examinee and the mouse in the same frame; and the monitoring module transmits the pictures to the server in the form of video stream. Therefore, the prisoner can monitor the operation of the examinee through the video, and ensure that the examinee himself operates the keyboard and the mouse.
Further, the camera is mounted on a movable or angle-adjustable support, and an examinee can adjust the camera to a proper angle according to the position and sitting posture of the examinee, so that the face and the keyboard/mouse can appear on a monitoring picture at the same time.
The invention further discloses a specific embodiment, referring to fig. 2, during the examination, the mouse and the keyboard start to record the operation of the examinee and the time of the operation.
The information acquired by the information acquisition module comprises: the left mouse button is clicked + the moment of the clock module at the moment, the right mouse button is clicked + the moment of the clock module at the moment, the mouse wheel is rolled + the moment of the clock module at the moment and the keys of the keyboard are clicked + the moment of the clock module at the moment.
In the examination process, the test taker first examination client module starts to record all the operations of the mouse and the keyboard connected to the computer, and the recorded contents are consistent with the recorded forms of the mouse component and the keyboard component sent to the test taker, namely: there is a time when the left mouse button is clicked + a time when the right mouse button is clicked + a time when the mouse wheel is scrolled + a time when the keyboard button is tapped.
In the examination process, the server displays a list of examinees who are in examination: examinees a, b, c, etc., each taking part in the remote examination in the same manner as the examinees a.
For example, if the prisoner selects to click "the test taker's nail" on the server, the data comparison display module displays the current test taker's name, i.e. "test taker's nail".
In the examination process, cameras in a keyboard component and a mouse component of the examinee's first are used for shooting videos in real time, and video code streams are transmitted to a server. At the moment, when the invigilator selects and clicks 'examinee' on the server side, the invigilator can see at least 4 video pictures in the monitoring video group module of the server side: the method comprises the steps of performing in-frame video of the hands and the keyboard of the examinee, performing in-frame video of the faces and the keyboard of the examinee, performing in-frame video of the hands and the mouse of the examinee, and performing in-frame video of the faces and the mouse of the examinee; and the prisoner judges whether to operate the key mouse for the examinee's first person by comparing the face and hand actions of the examinee's first in the video and the operation of the on-site keyboard and the mouse.
Meanwhile, for example, as shown in fig. 2, the data uploaded by the data comparison information acquisition module of the server (left area) and the data transmitted by the display examination client module (right area). For example, the examinee first clicks the left mouse button once and the right mouse button once after 10:32:03.2 (10 points 32 parts for 3.2 seconds), and then enters an English word the and a space. All the data monitored by the mouse end and the examination client end at this time are completely consistent, namely the matching degree displayed by the data comparison display module is 100%. Assuming that the matching degree threshold set by the server is 98% (the threshold is necessarily smaller than 1), and the real-time matching degree is larger than the threshold at the moment, so that the value beside the matching degree of the server is displayed as normal; if the client module records the operation record which is not from the keyboard and mouse component, and the matching degree is less than the threshold value at a certain moment, an alarm is displayed beside the matching degree value, so that the prison teacher's examinee is prompted to possibly have cheating actions input by other keyboard and mouse.
In other examples, as shown in fig. 3, a camera group is arranged in front of the keyboard, and the position of the camera group is relatively unchanged from that of the keyboard; one camera shoots the same frame picture of the keyboard, the hands of the user and the faces of the user, and the other camera shoots the key close-up picture of the keyboard; in the use process, the angle and the position of the camera are not adjustable; each key of the keyboard is provided with a key color bar; in the picture, the acquisition module judges and records which key is pressed according to the displacement of each keyboard key color bar or whether the color spot of the detected key is covered.
