4. Why Mobile Users Need PDF SignCheck
Most citizens in Karnataka download and view their Seva Sindhu certificates on Android and iOS mobile devices. However, mobile web browsers (like Chrome or Safari) and built-in PDF viewers completely ignore embedded digital signatures, showing no signature status at all. PDF SignCheck runs completely in your mobile browser, executing checks in-memory with zero file storage, providing Karnataka mobile users with instant verified stamps.
5. Legal Validity of Digital Signatures under the IT Act, 2000
According to Section 5 of the Information Technology Act, 2000, electronic signatures validated against a licensed Certifying Authority (like those under the CCA India root) hold the same legal status as traditional handwritten signatures. They are legally binding and accepted by all government offices, courts, and banks. In Karnataka, certificates issued through Seva Sindhu and signed by NIC Karnataka CA are fully valid once cryptographically verified. Karnataka certificates use NIC Karnataka CA credentials, which are licensed under the CCA India trust root.
