A software package is received and unpacked into multiple components comprising plural functions. Each function is lifted from machine code into static single-assignment intermediate representation and tokenized to produce semantics-preserving embeddings. Intermediate-representation data-flow features are extracted, including detection of constant static variables on a stack, stack reaching definitions, uninitialized variables, and intra-procedural aliases. For each component, the embeddings and features are input to a machine-learning model trained on semantic properties derived from a corpus of software packages to generate a software supply chain risk level. Data characterizing the risk level is provided to a consuming application. When the risk level satisfies a remediation criterion, a remediation action is initiated, including generation of a source-code patch recommendation for an identified root-cause function, insertion of a runtime guard into the component, or issuance of a security advisory for distribution to a security operations dashboard.

The application provides a privacy record linkage method and system for semantic heterogeneous data, involving multiple linkage participants and a linkage unit. Firstly, the attribute is divided into strong and weak categories by calculating the average difference of semantic similarity of data attribute characters. For weak semantic attributes, an improved CLK-CRBF counter Bloom filter is used to generate integer encoding. For strong semantic attributes, a fine-tuning embedding model is used to generate a dense vector. Then, the integer encoding is fused as a structured disturbance with the dense vector to form a semantic-aware encoding vector and sent to the linkage unit. The linkage unit uses locally sensitive hashing in an adaptive hybrid encoding space to block, generate candidate record pairs in the group, and calculate the similarity. Finally, the matching result is determined according to the negotiated threshold. The method significantly improves the linkage effect of semantic heterogeneous data while ensuring privacy, and the greater the data difference ratio, the more obvious the advantage.

According to the multi-object video editing method based on semantic perception content alignment provided by the invention, a precise semantic-level editing effect with consistent time sequence can be realized in a multi-object video without training a diffusion model. Effective semantic alignment is realized through two core mechanisms of semantic adaptive modulation and semantic prior modeling. Specifically, coupling semantic features among multiple objects are effectively decoupled through an attention regulation and control mechanism of region perception and text perception, so that the model can accurately position the spatial position and semantic attribute of each object; meanwhile, cross-modal semantic consistency supervision is constructed based on a pre-trained visual language model, and the diffusion sampling process is guided to keep global semantic consistency with text editing prompt. Experimental results show that the method is remarkably superior to the prior art in the aspects of semantic alignment, editing precision and visual consistency, can be widely applied to the fields of film and television production, human-computer interaction, digital media creation and the like, and has excellent practical value.
