# A Novel Cryptography-Based Architecture for Secure Data Asset Sharing and Circulation Systems
## 6 System Implementation
### Security Outsourcing Storage Module  
In the security outsourcing storage function module, the visual presentation and analysis of the security protection status of data assets in the outsourced storage process are realized through components such as Amap, water wave dashboard, percentage bar chart, tree chart, data search view and scattered Gantt chart, as shown in Figure 9.  
The Amap shows the distribution of data asset storage nodes. When hovering over a node, a pop-up window containing detailed information such as storage device number, storage status, IP address, security configuration policy, data throughput, etc., is displayed. When a node is clicked, the water wave dashboard dynamically updates the currently selected node to visually display the device storage usage rate and security policy status. Through the water wave dashboard, managers can monitor the changing trend of equipment storage utilization rate in real time. When the storage utilization rate is close to the alert line, managers can expand the storage capacity or clean data in time by observing the water wave height. In addition, by comparing the storage usage rate at different time points, we can analyze the storage growth pattern, predict the future storage demand, and provide decision support for capacity planning and security configuration strategy adjustment. The percentage bar chart shows the longitudinal comparison information of the throughput of data inflow and outflow of storage devices, reflecting the overall change in data throughput. Through the percentage bar chart, managers can quickly identify storage devices with abnormal network traffic and adjust security protection policies in time. For example, when the proportion of inbound or outbound traffic of a device deviates significantly from the normal range, it may indicate network attacks or equipment failures. At this time, the corresponding security configuration policies will be re-issued and modified. The tree chart shows the distribution of security configuration policies of storage devices. The storage devices configured with the same policy are divided into groups, and each group is distinguished by different colors. Different devices in the same group are presented in slices. Through tree diagram, managers can quickly locate problem devices. For example, by analyzing the number of slices and redundancy under different policies, they can evaluate the fault tolerance of security protection. In a scatter Gantt chart, the life cycle of a secure storage policy is displayed on a time axis, including creation time, effective time, and expiration time. In the data search interface, the table displays the policy number, status, number of slices and other conditions for filtering. Through scatter Gantt chart, managers can find the rules and problems of strategy formulation by observing the time distribution of strategy creation, effectiveness and invalidation. For example, finding that a

large number of policies fail in a short period of time may indicate that there is a problem in the formulation of security configuration policies, which need to be modified in time.
