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.
