Evolution from seal signature to e-signature

The digital signature is a digital method of ensuring the correctness of the identity of people by saving time and cost to a great extent. The digital signature method uses public-key cryptography. This method is also known as asymmetric cryptography. Using the public key encryption algorithm, one can generate two keys which are known as the public key and private key. The digital signature works with the help of these two mutually authenticated keys. Here the person who is creating the digital signature uses the private key to encrypt the document which is to be signed and this document can only be decrypted using the public key of the signer. This way is used to do the authentication of digital signatures . The digital signature method makes all the parties believe that the created digital signature by the individual is kept secret and does not make the fraudulent mechanisms by the private key holder. A one-way hash of digital data to be signed is generated when one tries

Digital Signature ensures the identity of the person with the help of digital media which is an innovation over traditional human signature method. It has many benefits over the conventional methods of signature, which improves the day to day life of the people. The very first benefit of the digital signature is to save the time of individuals. Businesses can save time and cost by the use of digital signature as the signing of documents and contracts can be done in just one click. By the use of digital signature , one need not wait for the authorities to be there in their office for getting the documents signed. Documents can get signed instantly from any geographical location. The electronic gadgets like mobile phone, tablet, desktop or laptop systems can be used to implement the digital signature method, which reduces the tedious work in seconds. The next benefit is the ability to save the cost of businesses by avoiding the expenses of ink, paper, printing, scanning, shipp

Digital Signature provides assurance to the proof about your origin, transactions, identity and using this one can acknowledge consent by the signer. This technique, to an extend helps to prevent impersonation in digital world and also helps to avoid tampering of handwritten signature and stamped seal. So, as a result digital signature is a method to confirm integrity and authenticity of software, digital documents and messages. Nowadays all around the world adopts the concept of digital signature instead of conventional handwritten signatures. The US government now legally accepts the electronic representation of their budgets, congressional bills and their laws using digital signature. A digital signature can be used with either encrypted or unencrypted messages, and the receiver can ensure the genuinity of the sender’s message. The digital signature is always distinctive for the signer and the document. This process is called non-repudiation. This makes the signer not to d

Centuries back the way of reaching to a mutual agreement was by signing contracts using several physical seal methods. As technology evolved the signing agreements become digital, this made the process more secure and safe. The idea of digital signature was a contribution by Ronald Rivest, Len Adleman and Adi Shamir by their invention of RSA algorithm on 1977 which was the earliest digital signature method. The method of digital signatures were accepted legally up in court and have equal acceptance as same as that of a normal signature in a document. A digital signature certificate is represented using a digital key. This digital key is provided by the certifying authority which helps to verify the credentials of a person which helps to identify that particular person. These signatures are generated using public key encryption method. The major details included in a digital signature certificate is the user’s name, email, pin code, country and the date in which certificate issue
