Which technology is often used to ensure the security and authenticity of digital documents in e-governance ?

The correct answer is Digital signatures.

Key Points

• Digital signatures are often used to ensure the security and authenticity of digital documents in e-governance.
• They are a mathematical technique that allows the sender of a digital message to sign the message in such a way that it can be verified by the recipient.
• This ensures that the message has not been tampered with since it was sent, and that it was indeed sent by the person who claims to have sent it.

Additional Information

• Virtual Private Networks (VPNs) are used to create a secure connection between two or more computers over the internet. They can be used to protect the privacy of data that is being transmitted, but they do not provide any authentication or integrity guarantees.
• Distributed Ledger Technology (DLT) is a type of database that is shared across multiple computers. It can be used to store digital records in a secure and tamper-proof way. However, DLT is not yet widely used in e-governance, and it is not yet clear how it will be used to ensure the security and authenticity of digital documents.
• Cloud computing is a way of storing and accessing data and applications over the internet. It can be used to store digital documents, but it does not provide any security or authentication guarantees.
