A Tamper-Proof Digital Signing Solution based on a Digital Signature Certificate (DSC) ensures secure, legally recognized electronic signing. Using PKI encryption, the DSC verifies the signer’s identity and locks the document against any unauthorized changes after signing. It guarantees authenticity, data integrity, and non-repudiation, making it ideal for e-tendering, GST, MCA, income tax filings, and other government and business compliance processes under the IT Act.
