This invention discloses a method and system for managing chat logs based on a storage network, relating to the field of log management technology. The method includes the following steps: S1, constructing an interaction matrix; S2, constructing an association matrix; S3, calculating participation; S4, outputting summary text; and S5, assessing risk coefficients. This invention effectively divides different chat logs by constructing an interaction matrix and marks chat logs within the same conversation segment. After the initial construction of the interaction matrix, to further conserve storage resources, the position values ​​in the matrix are optimized: if the logical correlation between two chat logs is weak, the value at the corresponding matrix position is reset to zero, thus avoiding redundant storage; while for strongly correlated log pairs, their position value is retained as 1. This design quantifies the connection strength between chat logs, thereby reflecting the closeness of the relationship between users.

The data query method and the data query system provided by the embodiments of the present application relate to the technical field of data processing. First, a data providing end divides a database into multiple sub-databases and forms multiple mixed sub-databases, and the sub-databases and the mixed sub-databases cannot communicate with each other; then, multiple random query data vectors generated based on a query data vector are respectively sent to the multiple sub-databases and the multiple mixed sub-databases; then, the data providing end calculates a query return value based on the received multiple random query data vectors; finally, a data querying end judges whether there is to-be-queried data in the data providing end based on the query return value. Compared with the prior art, different sub-databases or mixed sub-databases cannot communicate, and any one of them can only obtain part of the random query data vectors forming the query data vector, so that the information security between the data querying end and the data providing end in the data query process can be ensured.

This invention provides a method for exchanging power market trading platform server, client, and clearing cases, comprising: the server in the operating environment compressing and encrypting power market optimization clearing data in the platform database into case information files according to data type and storing them; the client extracting the stored case information files, encrypting them to form case exchange files, and outputting them to a target location; the client in the laboratory environment reading, decrypting, decompressing, and verifying the case exchange files at the target location to form case files, which are then stored in the server; the loading module of the server extracting and decompressing the stored case information files into optimization clearing data and storing it in the platform database in the laboratory environment. The case information exchanged in this invention adopts a step-by-step encryption method to ensure the security of core data of market members in the case files, ensure that the case files can only be exchanged within the trading platform, and ensure that the multi-encrypted case exchange files cannot be decrypted offline.
