AI Technical Summary
The electronic signature process for civil aviation scheduled maintenance work cards suffers from problems such as complex signatures, long cycles, and frequent record modifications. This leads to reliance on traditional paper records and difficulty in ensuring the legality of electronic records, hindering the improvement of civil aviation operational efficiency and safety.
The system uses hash algorithms based on OID, CID, and PID to generate unique identifiers for work cards and processes. Combined with the SM2 electronic signature algorithm, it achieves the independence and relevance of processes, supports multi-person collaborative signing and frequent modifications, and generates structured PDF records to ensure the non-repudiation and traceability of electronic signatures.
It achieves non-repudiation and independence of electronic signatures for scheduled maintenance work cards, solves the problem of overlapping signature ranges in multi-person collaborative signing, meets the requirements of legality and credibility of electronic records, and supports frequent modification and traceability of records.
