The invention provides a storage encryption system and method, and the system comprises a connection and recognition module, a data preprocessing and preliminary encryption module, a platform building module, a pseudonym building module, a secret key generation and management module, an asymmetric encryption module, and a data storage and access control module. According to the storage encryption system and method provided by the invention, the access strategy is further encrypted by combining the pseudonyms with the leaf nodes of the binary tree, the attribute information of the user is stored by using the binary tree structure, and each leaf node is associated with one pseudonym, so that the data security is enhanced, and the user experience is improved. According to the technical scheme, unauthorized access and data leakage are effectively prevented, access rules and access control are set, a user is allowed to access a data block of a specific version instead of data blocks of all versions, data safety is improved, and unnecessary loss caused by leakage of important information is avoided.

This invention provides a multi-component liquid dispensing system, relating to the field of biopharmaceutical laboratory technology. It comprises a liquid delivery system, a quantitative system, an error-prevention system, and supporting software. The liquid delivery system includes a main base, a peristaltic pump module, and an upper tube rack. The peristaltic pump module is fixedly connected to the top of the main base. A precision balance is mounted on the upper part of the main base. A side Z-shaped slide rail is symmetrically fixedly connected to the top of the main base. An upper connecting bracket is fixedly connected to the middle of the side Z-shaped slide rail. A positioning column is slidably connected to the upper end of the upper connecting bracket. A central support spring is fixedly connected between the positioning column and the upper connecting bracket. A tube rack is fixedly connected to the middle of the main base. This invention enables automatic liquid addition and quantitative dispensing, avoiding errors caused by missed additions, duplicate additions, and manual addition. It replaces most manual operations and solves the problems of high workload, inter-bottle and batch variations, and difficulty in maintaining product formula confidentiality during large-scale product preparation.
