Method and system for maximizing sales profits by automatic display promotion optimization

The present invention is remotely controlled automatic optimization system for maximizing in-store net profits by customized script-generated clip promotions to thousands of individually networked retail display-nodes from central server (OptiRetailChain). The computer-based and machine-learning display system includes: an advertising optimization function for display nodes, point of sale (POS) data input, retail database mining engine (RDME), client access and management control module, and in-store networked electronic clip display apparatus. The optimization function obtains data from chain-store database, combines product bundling data, which describe the associative relationships of various product sales in stores with recorded times of sale, inventory costs, margin profits etc. Physical location of purchased products on the store floor-areas are correlated with relevant display-nodes to create optimal clip display program (playlist) configurations for that specific display location and time. Most preferred product advertising combinations will be displayed in the best time slots for each node automatically. OptiRetailChain uses two methods of promotion optimization: real time scheduling and longer-term statistical optimization. Utilizing the machine learning capabilities, actual video-clip playlists will be dynamically updated for every display-node and respond to daily sales fluctuations for that store display location. This enables the optimization system to effectively control and automatically feature target advertising to large number of display-nodes in supermarket chain networks optimizing advertising capital without necessitating outside intervention.

Electronic evidence preservation system and method based on block chain technology

The invention discloses an electronic evidence preservation system and method based on the block chain technology. The preservation system comprises an evidence storage terminal and a block chain network. The evidence storage terminal comprises a hash operation module and an electronic signature module. The electronic data are uploaded to the evidence storage terminal, the evidence storage terminal performs hash operation on the uploaded electronic data to generate unique feature data of a fixed length of original data; then private key signature is performed on the generated data by using theasymmetric encryption technology, and the generated data are sent to the block chain network; and the block chain network performs primary consensus on the uploaded data and packs the uploaded data into blocks, and synchronously sends the blocks to nodes in the network for distributed storage. By establishing an evidence storage alliance by using the block chain technology, the electronic evidence preservation system has the characteristics of digitalized encryption, centralized grading, anti-tampering, data zero loss and so on. Each node in the block chain can preserve a complete block chaindata copy and witness the chain status of the blocks, so that the centralization risk can be effectively avoided.

Multi-party trusted identity authentication method and system based on block chain

The invention discloses a multi-party trusted identity authentication method and system based on a block chain, and belongs to the field of Internet identity authentication. The technical problem to be solved is to realize identity authentication of a user in a plurality of application systems based on the block chain, securely store the user information in the identity authentication process through the block chain and really and completely verify the user identity. The method comprises the following steps: an application system generates user attribute card information according to a received registration request, encrypts the user attribute card information and issues the user attribute card information to the block chain, wherein a plurality of application systems are provided, and the encrypted user attribute card information corresponding to each application system is stored in the block chain; each application system verifies the user identity based on the block chain. The system structurally comprises a block chain network, a client authentication module configured in a client and an application server authentication module configured in the application system. By adoption of the multi-party trusted identity authentication method and system, the real name information of the user is stored in the block chain securely and reliably, and the identity authentication of the user is implemented really and completely through the block chain.

Dynamic node management method realized based on BFT consensus algorithm

The invention discloses a dynamic node management method realized based on a BFT consensus algorithm. The management method comprises the following steps: a new node obtains the admission and participation consensus qualification of a block chain network through offline certificate acquisition on the block chain network, and requests the connection to the existing node of the whole network so as to successfully join in the consensus after the verification is passed; when requesting to exit the block chain network, one node requests the exiting to the whole network, and successfully exits the block chain network after each node administrator agrees the exiting. The specific step of newly adding the node is as follows: the new node acquires the connection information of the whole network after passing the introducer node connection by taking the CA certificate, and then joins in the block chain network through the whole network consensus and the accomplishment of the synchronization of the new node. The specific step of deleting the node is as follows: the node in opt-out broadcasts the exit request to the whole network, each node administrator agrees to the exiting and broadcasts the deletion of the exiting node to the whole network; when the whole network consensus agrees to the node exiting, the respective connection is updated, and the connection with the opt-out node is interrupted, and the node is cleared from the block chain network.
