Foundation of Digital Signature uses

A digital signature is precisely an electronic form of signature used to authenticate any digital document and identity of the signer. It is important and in vogue because it is safer and secure than traditional pen-paper signatures. The electronic signature is complicated to falsify because it operates through mathematical algorithms. Due to its easy nature, encryption capabilities it can be adapted by different businesses. In the 21st century, there are several digital signature uses, important for restructuring and revamping any business model.

Digital signatures are available for a long time but the passing of The Electronic Signatures in Global and National Commerce Act or ESIGN in the year 2000, gave the process a greater legal standing.

Since then, it has been adapted by several organizations throughout the world due to its promise of enhanced security and additional safety for signed documents. The digital signature process is a complex one. It uses a cryptographic method where a pair of keys are used for the verification and protection of a document. The private key encrypts the document and it is accessible only by the signer.

The public key is used for the decryption process by the receiver. But in order to use this process, both the signer and the receiver must have a digital certificate that is issued by the Certificate Authority.

Due to the booming potential of digital signature, organizations and industries have started its implementation in different sectors.

The digital signature works as an electronic fingerprint. With a electronic signature, an individual is capable of signing a document digitally. The process protects the document from falsification and provides verification of the deed.
