It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is as follows:
in order to solve the problem that the electronic large-screen display of the current venue is easily invaded by an illegal user to control the released content, the embodiment provides a large-screen display control system based on an ether house block chain, please refer to fig. 1, which includes a control terminal 11, a display large screen and an ether house network 13; by utilizing an Ethengfang block chain signature verification mechanism, the effect that only a set control terminal can send an instruction to the large display screen to control the large display screen to display contents is realized; the safety of large-screen display is improved, the risk that the large-screen putting authority is illegally invaded is reduced, and the normal display of large-screen putting is ensured; meanwhile, the record is permanently stored through an Ethernet workshop network; therefore, the electronic large-screen display content of the venue is guaranteed to be lost.
The control terminal 11 is used for acquiring the release control information, signing the release control information, initiating a transaction, and sending the signature information and the release control information to the display large screen through the Ethenhouse public link network; the delivery control information includes delivery content and/or delivery control instructions.
The delivered content may be different based on different actual delivery requirements, for example, text content, pictures, videos, and the like may be possible. Launch control instructions include, but are not limited to, launch start, launch pause, page jump/slide up and down, sound size adjustment, play speed adjustment, and the like.
Optionally, the access application may be pre-constructed for the setting control terminal, and used to access the ethernet public link network. For example, android/ios-based mobile phone applications or Windows/mac-based computer-side applications are designed and developed, and the main functions include text, picture and video input and uploading, and accessing an Ethernet public link node, so that the method aims to upload original materials to be released in a venue, and release content and control instruction uplink preparation are realized through client-side applications.
After the original material to be released is input into the client, the control terminal performs hash operation on release control information by adopting a set hash algorithm to obtain target abstract information; and encrypting the target abstract information by using a self private key to realize signature. After encryption, initiating a transaction, submitting a client to an Ethengfang network, wherein the client comprises a receiver address, a sender signature and release control information, adding the transaction information into a transaction pool through Ethengfang block nodes, verifying the signature, and broadcasting the signature to other nodes of the Ethengfang; waiting for the spaciousness packaging process, then packaging the transaction information by the spaciousness, and synchronizing to all nodes.
In other embodiments of the present invention, the control terminal 11 is configured to obtain a public key for displaying the large screen 12 before sending the launch control information to the large display screen 12 through the ethernet public link network, and encrypt the launch control information by using the public key; the display large screen 12 is used for receiving the encrypted release control information, decrypting the release control information by using a private key of the display large screen, and performing hash operation on the decrypted release control information by using a set hash algorithm to obtain target abstract information.
