Problems solved by technology
[0004] At present, there are many electronic whiteboard products on the Internet. For example, whiteboards in instant messaging tools are all one-way, that is, after editing a picture, the generated picture is sent to the other party, which cannot realize real-time whiteboard communication. ; At present, there are also many video conferencing and distance education systems that realize real-time synchronous electronic whiteboards, but these whiteboards need to download software for installation, and there are certain requirements for software, hardware, and costs. These are the limitations of current electronic whiteboard functions. insufficient
In addition, the synchronization information in the existing synchronization solutions is passively received, which cannot be effectively authenticated and controlled, and may easily cause security risks

Embodiment Construction
[0014] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0015] The present invention comprises the following steps:
[0016] Step 101: When the source user is operating on the whiteboard, when the mouse is pressed, start recording the current coordinates of the mouse on the whiteboard and start marking it into an array variable.
[0017] In the above technical solution, step 101 includes the following process:
[0018] When the source user operates on the whiteboard, when the source user presses the mouse, the coordinates of the mouse on the whiteboard and the start mark are recorded in the array variable of Flash.
[0019] Step 102: Record the coordinates of the mouse on the whiteboard into an array variable during the mouse movement.
[0020] In the ...

The invention discloses an electronic whiteboard safety synchronizing method based on a webpage, comprising the following steps of authenticating the authority of a received whiteboard synchronous information instruction sent by a source user by a communication server; after passing the authentication, subsequently authenticating the authority of a target user on receiving the whiteboard synchronous information instruction; and after passing the authentication, sending whiteboard synchronous information instructions to the target user. The invention also discloses an electronic whiteboard safety synchronous system based on the webpage. The invention realizes the aim of safely synchronizing the electronic whiteboard without downloading and installing any software.
Description
technical field [0001] The invention belongs to the field of network technology, in particular to a webpage-based electronic whiteboard security synchronization method and system. Background technique [0002] The development of Internet technology enables us to realize instant messaging, chat with friends, negotiate with partners and so on without leaving home. At present, based on the instant messaging tools that need to be downloaded and installed, such as MSN, QQ, and Netease Bubbles, they have been deeply loved by everyone. It provides a new way for people to communicate and exchange information. Another important way of information exchange; with the help of these tools, users can realize single-person or multi-person video, hold online video conferences, conduct online distance education, and greatly reduce the cost of communication between people. , and improved efficiency. [0003] Text communication, audio communication, and video communication are the three most...
