In 1976, Whitfield Diffie and Martin Hellman worked the first time on a digital signature scheme. At this point in time, they only conjectured that such schemes existed based on functions that are trapdoor one-way permutations.

In 1982, Adobe was founded by John Warnock and Charles Geschke, who established the company after leaving Xerox PARC in order to develop and sell the PostScript page description language. When they presented the PostScript idea to Xerox the management team was not convinced. They named the company after the Adobe Greek which runs in Los Altos, California right behind Warnock’s house.

In 1991, Adobe co-founder John Warnock launched the paper-to-digital revolution with an idea he called, The Camelot Project. The goal was to enable anyone to capture documents from any application, send electronic versions of these documents anywhere, and view and print them on any system. One year later Camelot had developed into PDF.

Today, PDF format is standardized and owned by the ISO and trusted by businesses around the world as a document format.

In 1999, Adobe introduced the first digital signatures in the PDF tools Adobe Acrobat and Adobe Acrobat Reader. Adobe worked with experts and certificate providers across the industry to turn it into an open standard.

Adopted by ETSI, the international standard known as PAdES (PDF Advanced Electronic Signatures) is now the basis for billions of signature transactions every year.

Digital signatures use a certificate-based digital ID issued by an accredited Certificate Authority (CA) or Trust Service Provider (TSP) so when you digitally sign a document, your identity is uniquely linked to you, the signature is bound to the document with encryption, and everything can be verified using underlying technology known as Public Key Infrastructure (PKI).

What is a Digital Signature?

With an electronic signature or e-signature, you can legally sign documents or participate in approval workflows or forms. They are legal, tested, secure, auditable, and verifiable. Digital Signatures are offering extended security like encryption and Digital IDs.

Digital signatures are the most advanced, compliant, and secure type of e-signature. When you need the highest level of assurance of each signer’s identity and document authenticity, opt for digital signatures.
