This application relates to the field of
information security technology and discloses a method for preserving trade secrets. The method includes constructing a confidential environment to generate encrypted documents; constructing a multi-level
project management structure and permission hierarchy for managing encrypted documents; collecting all encrypted documents and corresponding operation logs based on structured orders and calculating their respective hash values; managing emails; managing meetings; and periodically and incrementally uploading the hash values of all encrypted documents, the hash values of the operation logs corresponding to all encrypted documents, and the hash values of meeting minutes to a
blockchain-based evidence preservation platform. This application, based on the construction of a multi-level
project management structure, achieves orderly organization and precise permission control of trade secrets, ensuring timely, complete, and tamper-proof data, providing a clear trajectory for infringement tracing, facilitating rights protection, preventing data leakage, and meeting judicial
confidentiality requirements.
Blockchain evidence preservation and the generation of multi-dimensional evidence packages ensure
data authenticity and evidence integrity, enabling
rapid response to infringement disputes.
