Netrust nSeal ensures the data integrity of a physical document with the use of digital signatures.
nSeal preserves data integrity and assures authenticity of physical documents like contracts, share certificates, academic certificates, product authentication statement, etc. This is achieved by the use of digital signature, a digital code generated and authenticated by public key encryption, which is attached to the document to verify its content and the signer's identity.
nSeal embeds the digital signature as a QR code onto the document and protects your originals from forgery and from tampering. This QR code can then be read by a standard QR code scanner or a custom built mobile application on a smart device to provide immediate access and verification of the untampered original data and identity of the issuer of the document.
