In this blog post, Abhiraj Thakur, student NALSAR University of Law writes about e-signatures. These digital signatures have become very common nowadays and with ever-increasing connectivity in the country, they are sure to rise. He tries to explain through this blog post how Indian Law has dealt with it.


The use of signs, symbols and words to represent one’s identity has been the part of human history from a long time. Being unknown to words in the stone age, mankind drew pictures on the cave walls and later to express his identity he started writing his name or depicting it through symbols. These signs and symbols were often unique to an individual. Kings all over the world used coins, seals and stamps to assert their authority, this practice of representing one’s identity continues till today and widely known as a signature. eSignature-Digital-Signature

In most simplistic terms, a signature is a representation in form of mark or symbol specific to an individual that represents his identity.

Today, signatures have assumed much importance, we sign numerous times in the course of our daily life. For illiterate people, their thumbprint becomes their signature as it is unique for every individual.

E-Signature In Law

A signature being representative of one’s identity holds a very significant place in the legal arena. Under the law, when a person puts his/her signature on a document it signifies knowledge, approval, acceptance or obligation on his/her part. Signature holds a very important place under the Contract Law in India, as it is considered to be an acceptance of an offer. With the advent of technology, signatures have transformed greatly. With ever increasing online transactions, e-signatures have assumed an important place in cyberspace.

International Law dealing with E-signatures

global-law-firmThe United Nations in 1998 made an observation that increasing transactions in cyberspace over the recent years made it very necessary to have a legal framework dealing with e-signatures. Also, there existed much ambiguity regarding the legal effect of such authorizations from concerned individuals and the courts in various countries regularly tussled with the issue. Thus, a uniform legislative approach was adopted to deal with the problem.

As a result, the UNCITRAL Model Law on electronic signatures, 2001 was adopted. This comprehensive document inter alia laid down certain basic guidelines and procedures to be followed by member nations while formulating the law on e-signatures in their respective parliaments.


imagesThere are certain requisites of an electronic signature which every nation needs to ensure in their local laws, these are enshrined under Article 6 of the UNCITRAL Model law:

  1. Reliability: The first requisite is that the E-signature has to be reliable, for being reliable as well there are certain criteria. An E-signature can only be considered reliable if it has following:
  1. Retraceable: The technique used in making the technology is such that it can be easily linked to the original source(creator) the message whenever necessary.
  2. Controllable: The technique used must be such that it is under the control of the source.

Further, the technology should be such that any unwarranted alteration of the important data can be easily detected even after the signature has been affixed. Today, The UNCITRAL Model law on electronic signatures is the most comprehensive document dealing with e-signatures at length.

E-Signature in India

22736556_mlTaking cognizance of the UN observation in 1998, the Indian government took up the initiative to deal with e-signatures in the country. The Information Technology Act of 2000 is an act through which the concept of e-signatures was introduced in India for the first time. Prior to 2000, no statute or judicial pronouncement recognised e-signature. The e-signature enshrined in the IT Act is in compliance with the UNCITRAL Model Law of 2001.

Section 2(a) of the IT Act goes on to define what an e-signature is. It defines an electronic record to be electronically signed when it is authenticated by the subscriber by means of an electronic technique that is specified in the second schedule of the act and involves digital signature. The central government of the country by the virtue of the IT Act has the authority to declare a particular technique to be reliable or not, and it must satisfy the UNCITRAL model code.

Techniques to make E-Signatures

There are numerous techniques employed all over the world to make e-signatures, UNCITRAL model prescribes a list of valid techniques. The basic technology at work in designing e-signatures is of cryptography. Cryptography is the widely used phenomena to secure important messages and has been in use for a long time. Under cryptography, the message that needs to be preserved is encrypted or codified into a format which is unreadable for the ordinary people and only the individual having the requisite know-how of decrypting the code can read it.E-signature_regulation_coming_to_Europe

The Public Key Infrastructure Technique(PKI)

The PKI method is the most prevalent and one of the legal techniques of designing E-signatures today and is widely followed in various countries of the world including USA and Germany. The key technique makes use of two distinct keys in the formation of e-signatures. These are public and the private keys.

Symmetric Cryptography Method

The symmetric cryptography method also makes use of two keys to preserve the messages. The sender and the receiver both have same keys and so only two parties can read the message. This method is widely used in business contracts that take place online, where there are only two parties concerned.

Asymmetric Cryptography Method

This method also makes use of two keys, the public and the private key and both the parties have both the keys. The public key is accessible to the public at large while the private key is accessible only to the concerned user. This technique is used in government welfare programmes and company schemes with customers where a single party deals with many different people. India uses this method as it is prescribed by the IT Act.

Advantages of E-Signatures

  1. Identity: Electronic signatures help an individual to gain identity in the digital world. It signifies an approval from him/her which is unique in nature and can’t be misused.
  2. Secure: Electronic signatures being digital in nature and made by cryptographic technology cannot be validated by ordinary authentication procedures. Thus, the chances of tampering with it are minimal.
  3. Swift: It being digital based, makes the work fast and hassle free. Due to this e-signatures are today widely used in the corporate arena where companies want the work to be fast and secure. In most cases, the complete approval of documents is done in a matter of minutes, unlike days or hours in usual paperwork.
  4. Record-keeping: E-signatures help in better maintenance of personal records of an individual. Many nation-wide entrance exams in our country today make use of e-signatures for upload of individual documents.
  5. Green: Lastly, E-signatures can, in the long run, be very beneficial for our environment. As it is a paper saving method. Today when thousands of trees every year are cut down to make paper, use of e-signatures can prove to be a noble step in the direction of saving the environment.

Offences in case of Electronic Signatures

handcuffgavel_istockphoto_thinkstock_8This is the greatest limitation of the digital world, every day a new technology comes and the very next day comes another technology that can manipulate the former one. As e-signatures are representative of one’s identity, most the crimes associated with it are identity-based. Certain specific offences that can be committed with e-signatures are:

Identity Theft

It involves making false electronic signatures with fraudulent purposes etc. Identity theft is a punishable offence under Section 66C of the IT Act. The section prescribes the punishment of fine or imprisonment up to three years for the offence.


 In simplistic terms, Misrepresentation refers to suppression of vital facts in order to obtain assent to a contract in this case electronic record. When a person suppresses vital facts from the person giving assent to an electronic deed, it is the misrepresentation. Section 71 of the IT Act makes misrepresentation in case of e-signatures a punishable offence.

Publication of False e-signatures

Section 73 of the IT Act makes it a punishable offence. It can happen in either of the cases when a person publishes e-signatures which are not authorised by the source or when there is publication of e-signature which was revoked prior.

Creation of False e-signatures

There are a lot of unscrupulous programmers nowadays that illegally gain access to personal documents of people and further create false e-signatures. Section 74 of the IT Act makes creation or publication of false e-signatures a punishable offence for which punishment may range from two-year imprisonment or fine up to rupees 1 lakh.

New Updates

Recently, the Government of India launched the E(Sign) Programme which is one of the biggest initiative of its kind in the world. The programme aims to provide e-signing facility to Aadhar card holders in the country. The facility will be helpful in various purposes such as in opening bank accounts and availing other services where documents are required. It is thus clear that the prospect of e-signatures in India is bright. With more spreading of internet facilities in the country, there will be an increase in e-signatures. Though the technology boasts of being trustworthy and reliable but new challenges with the advent of new technologies are inevitable.


  1. E-signature or E-verification is really a great thing. No hassle, no queues. It should be applied for everything which requires signature.
