一种电力异构移动应用平台多端离线消息存储方法
By processing permission identifiers and message index information on both the server and terminal sides, the invalidation status of offline message records is dynamically updated, solving the problem of inconsistent permission changes in multi-terminal offline messaging systems and achieving secure control and traceability of offline messages.

AI Technical Summary
Existing multi-terminal offline messaging systems cannot reliably control the invalidation of local offline messages on terminals when permissions are changed. This means that sensitive information may still be viewed and disseminated even after permissions are restricted, which violates the confidentiality and compliance requirements of the power industry.
Offline message records carrying permission identification information and message index information are generated on the server side, and a permission status table is built on the terminal side. The invalidation handling of local offline message records is dynamically updated through permission change commands. Combined with the terminal permission tracking table, consistent invalidation control of offline messages across multiple terminals is achieved.
It achieves consistent control over the failure status of offline messages in scenarios involving multiple terminals and long-term operation in weak networks, reducing the risk of sensitive information leakage and improving the controllability and traceability of permission contraction execution.
