Why sign with ABSign
Instead of affixing a signature to a picture, a verifiable record of the signature is generated.
Tamper Resistance and Timestamps
After each contract is signed, a hash certificate and a trusted timestamp are generated. Once the contract content is modified, the verification will fail.
Verifiable in multiple jurisdictions
The signing record contains the signer’s identity, IP, time and device information, which can be independently verified and does not rely on any single party.
Data encryption and isolation
Transmission and storage are fully encrypted, contract content is isolated by tenant, and complies with ESIGN, eIDAS and PIPL requirements.
