Specific embodiment
The embodiment of the present application provides a kind of record screen evidence collecting method, system and electronic equipment based on block chain.
In order to make those skilled in the art better understand the technical solutions in the application, below in conjunction with the application reality
The attached drawing in example is applied, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described implementation
Example is merely a part but not all of the embodiments of the present application.Based on the embodiment in the application, this field is common
The application protection all should belong in technical staff's every other embodiment obtained without creative efforts
Range.
Fig. 1 is record screen evidence collecting method flow chart of the one embodiment based on block chain of the application.The method of Fig. 1 can wrap
It includes:
S110 shields the call request of intelligent contract in response to the local record of block chain, obtains the local record screen intelligence and closes
About, it includes for realizing the local code for recording screen process that the local record, which is shielded in intelligent contract,.
Wherein, the local record screen process includes at least starting screen recording function, executes machine operational order, Yi Jijie
Beam screen recording is to generate record screen file.
It should be understood that generally comprise two class accounts in the block catenary system with intelligent contract, i.e., it is external to possess account
(External Owned Account, EOA) and contract account (Contract Account, CA).In the embodiment of the present application,
The call request of intelligent contract is shielded in local record, be can be and is called directly by EOA, or by EOA call other intelligent contracts with
Connect calling.It should be understood, of course, that under normal circumstances, local record is shielded intelligent contract and is called by EOA.
