How does a digital signature protect against document tampering in India?

A digital signature protects against document tampering in India by using cryptographic algorithms. When a document is digitally signed, a unique hash value is generated based on the document’s content. This hash value is then encrypted using the signer’s private key, creating the digital signature. If any alteration is made to the signed document, the hash value will change, rendering the signature invalid. Therefore, a digital signature provides assurance that the document has not been tampered with after it was signed.
