From traditional handwritten signatures, we have moved towards advanced digital security technologies. It is time to look into the history and each poignant moment of development of eSignatures.
The Origins: Signatures on Paper
Signatures have long been used to verify identity and show agreement. Initially, people used handwritten signatures on paper documents, such as contracts, letters, and legal papers. This laid the foundation for developing more secure and efficient methods to sign documents.
3500 BC: The Birth of Signatures
Seals were the earliest form of signatures and were in use with the Sumerians circa 3500 BC. Mostly mounted on small round cylinders, they were pressed into wet clay to leave a distinctive impression. Seals served as an identification mark and authentication means for official documents, business transactions, and personal belongings.
AD 57: Hanko Seal in Japan
In AD 57, the Hanko seal emerged in Japan as a signature of authority and ownership. Indeed, Hankos are still in use in Japanese culture for legal and personal purposes today. The Hanko seal is almost a singular, very personal mark that is etched in Japanese tradition and society.
1600s: Signatures on Paper
The move from seals to paper happened in the 17th century. The more people learned to read and write, the more complicated and distinctive signatures became, reflecting the person who was signing. Written signatures became common since they provided much more convenient way of approval. During the Renaissance and the Industrial Age, handwritten signatures became crucial for business. Contracts and agreements needed signatures to be legally binding, ensuring that both parties were in agreement. In 1677, the Parliament of England made it a law that certain contracts must include a signature to be legally valid, highlighting the importance of signatures on paper documents.
1867: Statute of Frauds
In the year 1867, the enactment of the Statute of Frauds legalized other forms of signature that could fulfill the legal requirement of having written agreements. This paved the way for innovations like the telegraphed signature in 1918, audio recordings in 1972, and finally, the fax machine in 1988. These alternative methods were major breakthroughs, making it easier and more efficient to sign documents.
20th Century: The Rise and Fall of Fax Machines
The 20th century saw the rise of fax machines as a popular way to send documents with legally constitutional signatures. Invented in the mid-19th century, fax machines became widely used in the 1980s.
The Digital Age: Birth of Digital Signatures
The late 20th century brought the digital age, introducing digital security technology. One of the key developments was the introduction of Public Key Infrastructure (PKI), which made digital signatures possible. Unlike handwritten signatures, digital signatures use cryptographic algorithms to ensure that the document hasn’t been altered since it was signed and to verify the identity of the signer. This marked a significant milestone in the evolution of electronic signatures.
1976: The Concept of Digital Signatures
The concept of a digital signature scheme was first described in 1976 by Whitfield Diffie and Martin Hellman. They assumed the existence of such schemes based on functions that are trapdoor one-way permutations.
“The first recorded use of an electronic signature dates back to the early 1970s. Dr. Whitfield Diffie, a professor at Stanford University, used a teletype machine to sign a contract electronically. This early form of eSignature was a precursor to the advanced digital signatures we use today.”
1977: RSA Algorithm
In 1977, Ronald Rivest, Adi Shamir, and Len Adleman invented the RSA algorithm, which is still the most pervasive digital signature algorithm. Initially, it was used for generating simple digital signatures only as a proof of concept. Their company, RSA Security, was formed in 1982 and later contributed to the formation of VeriSign in 1995.
1988: Security Requirements for Digital Signatures
In 1988, Shafi Goldwasser, Silvio Micali, and Ronald Rivest defined the security requirements of digital signature schemes. They detailed different attack models on signature schemes and thereby helped make eSignatures more secure.
1989: Lotus Notes
Lotus Notes 1.0, launched in 1989, was the first software to use digital signatures with the RSA algorithm.
1996: European Commission Framework
In 1996, the European Commission laid the foundation for consistent measures across its member states in ensuring the integrity and authenticity of electronic documents in transmission.
1997: Digital Signature Laws
In 1997, Italy and Germany were among the first countries to issue digital signature laws based on the use of registered public keys.
1999: Adobe’s Digital Signatures
In 1999, Adobe introduced digital signatures in its PDF tools, Adobe Acrobat and Adobe Acrobat Reader, with encryption registered with ESTI. The international standard known as PAdES (PDF Advanced Electronic Signatures) now underpins billions of signature transactions every year.
How Digital Signatures Work
The digital signature is a form of electronic signature enabled through cryptographic technology. They have two keys: one private, known to the person who will sign, and one public, available to all correspondents. Digital signing involves uniquely hashing the document, which is then encrypted using the signer’s private key. This encrypted hash combined with the signer’s public key constitutes the digital signature. If the signed document is modified, then the signature becomes invalid, thus ensuring the document is integral and authentic.
Legal Recognition: E-SIGN Act and eIDAS Regulation
The early 2000s saw the legal recognition of electronic signatures. In the United States, the Electronic Signatures in Global and National Commerce Act (E-SIGN) Act came in the year 2000 and stated that electronically placed signatures would be treated as valid as handwritten ones. In Europe, the eIDAS Regulation in 2016 created a single market framework for electronic signatures in the Member States of the EU. These laws provided the necessary legal impetus for the general adoption of electronic signatures.
The Impact of Legal Recognition
The E-SIGN Act and the eIDAS Regulation were crucial to the digital push towards electronic signatures, as they eliminated legal barriers and introduced clear regulations regarding the validity and enforceability of eSignatures, therefore allowing businesses to begin using them. As such, the general acceptance of eSignatures across multiple sectors like finance, real estate, health, and government led to more widespread use.
2008: PDF Becomes an Open Standard
In 2008, Adobe’s format of the PDF document became an open standard under ISO 32000. Digital signatures are part of this and allow new software solutions to make use of the PDF standard.
2011: Adobe Sign
In 2011, Adobe announced Adobe Sign, the successor to EchoSign’s cloud-based electronic signature service. With Adobe Sign, one can efficiently prepare and send documents for eSignatures. Anyone can sign on any device—desktops or mobile phones—and the person issuing the document can follow every step from start to finish.
