为确保电子签署文档的真实性、完整性与法律可靠性，SIGN.GL 采用多层安全与验证机制，并尽量与广泛采用的行业标准保持一致。
Audit Trail & Traceability
Each signed document is associated with a detailed audit trail recording signing events, timestamps, and technical metadata related to the signing process.
审计轨迹与可追溯性
每一份已签文档都会对应一条详细的审计轨迹，用于记录签署事件、时间戳以及与签署过程相关的技术元数据。
Document Integrity Protection
SIGN.GL generates a SHA-256 cryptographic hash for every signed document. Any modification to the document after signing will change the hash value and immediately invalidate the integrity verification.
文档完整性保护
SIGN.GL 会为每一份已签文档生成 SHA-256 加密哈希。签署后对文档的任何修改都会改变哈希值，并立即导致完整性校验失效。
Trusted Digital Certificate Framework
Digital signatures are backed by a trusted certificate infrastructure and follow verification standards supported by major PDF readers and digital signature validation systems.
