Abstract: The embodiments of the disclosure disclose a method and system for cross-chain transfer of data based on decentralized identifiers. According to the disclosure, after receiving a data transfer transaction sent by a terminal of an original holder, a source chain reads a public key of the original holder in a corresponding first BID document according to a first BID carried by the data transfer transaction, and verifies a signature carried by the data transfer transaction. After the signature passes verification, the source chain initiates a cross-chain transaction. In response to the cross-chain transaction, a target chain deploys a second BID document in the target chain, and a public key of a new holder and data to be transferred are recorded in the second BID document. Further, the source chain replaces the public key of the original holder in the first BID document with the public key of the new holder.

Abstract: According to a present invention embodiment, software is analyzed for security vulnerabilities. Information from a security scan of code is analyzed to identify a security issue pertaining to a code portion. A machine learning model determines an initial risk factor score for the security issue based on a history of information pertaining to one or more prior security scans. The initial risk factor score is refined to produce an overall risk factor score for the security issue based on a confidence of the initial risk factor score. The initial risk factor score is refined based on one or more risk factor scores for operations within the code applied to a variable of the code portion. A classification of the security issue is determined as one of a valid security issue and a false positive based on the overall risk factor score.
