This invention relates to the field of bioengineering technology, specifically to an endogenous signal peptide element fused with the MF-αpro region and its applications. The endogenous signal peptide element is composed of an endogenous signal peptide from Pichia pastoris with the C-terminus fused with MF-αpro or with amino acids 38 to 51 of the MF-αpro region detached; the amino acid sequence of the MF-αpro region is shown in SEQ ID NO:8; the amino acid sequence of the MF-αpro region with detached amino acids 38 to 51 is shown in SEQ ID NO:10. This invention provides a complete solution from rational screening to functional verification to element optimization. The resulting highly efficient, patent-free signal peptide element is suitable for the production of industrial enzymes, pharmaceutical proteins, and diagnostic reagents.

This invention discloses an adversarial hint copyright verification method and device based on multi-model joint gradient optimization. Addressing the weaknesses of single-model fingerprint generation in terms of weak adversarial capabilities, poor transferability, and insufficient concealment, this invention constructs multiple downstream models to simulate technical variations of the original model series. It employs multi-model joint gradient optimization to generate adversarial hints with cross-model recognition capabilities as model fingerprint features. Copyright verification is achieved by detecting the specific response patterns of the test model to the adversarial hints. This invention relies on multiple downstream models to capture the most essential features of the original model. Adversarial hints optimized using these features possess stronger specificity and effectiveness, effectively addressing intellectual property risks such as model leakage and unauthorized distribution.

The application provides a blockchain-based verifiable keyword Top-K non-fuzzy query and fuzzy query method, and a scheme combines RSA accumulators, inverted indexes and prefix trees and other related technologies to construct an ADS, and realizes ranking search verification of non-fuzzy queries and fuzzy keywords. The framework of the application can enable light nodes to effectively verify the correctness of query results, and performs well in search, verification, storage and update operations, and has good practical value.
