Consider the following statements : A digital signature is 1. an electronic record that identifies the certifying authority issuing it 2. used to serve as a proof of identity of an individual to access information or server on Internet 3. an electronic method of signing an electronic document and ensuring that the original content is unchanged Which of the statements given above is/are correct?
Explanation
The correct answer is option C (Statement 3 only).
A digital signature is an electronic method of signing an electronic document[1], and authenticated digital signatures provide cryptographic proof that a stated entity signed a document and that the document hasn't been altered[2]. This confirms that statement 3 is correct.
Statement 1 is incorrect because it confuses a digital signature with a Digital Signature Certificate (DSC). A digital signature is an electronic method of signing an electronic document whereas a Digital Signature Certificate is a computer based record[3], and it is the certificate, not the signature itself, that Certifying Authorities (CAs) issue for electronic authentication of users in cyber world[4].
Statement 2 is also incorrect as it describes the function of digital certificates or authentication credentials used for identity verification and access control, rather than the primary purpose of a digital signature, which is to sign documents and ensure their integrity. Therefore, only statement 3 accurately describes what a digital signature is.

PROVENANCE & STUDY PATTERN
Full viewThis is a classic 'Definitional Precision' trap. UPSC exploits the colloquial confusion between a 'Digital Signature' (the mathematical process) and a 'Digital Signature Certificate' (the identity record). The question is fair but demands strict technical clarity over loose usage.
This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.
- Statement 1: Is a digital signature an electronic record that identifies the certifying authority that issued it?
- Statement 2: Is a digital signature used as proof of an individual's identity to access information or servers on the Internet?
- Statement 3: Is a digital signature an electronic method of signing an electronic document and ensuring that the original content has not been altered?
- Explicitly differentiates a digital signature from a Digital Signature Certificate (DSC), showing the DSC is a computer-based record while the digital signature is a signing method.
- Implies that identification information (the computer-based record) is associated with the certificate, not the signature method itself.
- States that Certifying Authorities (CAs) issue digital signature certificates, linking identification of issuing authority to the certificate.
- Supports the view that the CA identification is part of the certificate issuance process rather than the signature mechanism.
- Describes Digital Signature Certificates as being endorsed by a trusted Certifying Authority (CA), indicating the CA's role in certifying the certificate.
- Reinforces that the certificate (not the signature) carries the endorsement/identification from the CA.
Lists 'digital signature' among digital public goods alongside e-KYC and digital repositories, implying digital signatures function as part of official digital identification/verification systems.
A student could infer that, like other digital ID tools, a digital signature might carry metadata linking it to an issuing/ certifying authority and then check technical/legal sources for certificate contents.
Explains that an MICR code is a numeric identifier that uniquely denotes a bank and branch β an example of how digital/encoded data can explicitly identify an issuing authority.
By analogy, a student could reason that digital signatures might similarly include an identifier for the certifying authority (as MICR does for banks) and then verify whether certificate formats embed such identifiers.
Describes a central authority (UIDAI) that collects data and issues unique identity numbers, showing the pattern of a central body certifying/issuing digital identity artefacts.
A student could compare the role of UIDAI in issuing Aadhaar to the role of a certifying authority for digital signatures and look for legal/technical descriptions of issuer fields in digital certificates.
Defines 'public record' as an official register made by a public servant, illustrating that authoritative records commonly carry source/issuer information.
One could extend this idea to digital records: expect authoritative digital artefacts (like certificates) to record their issuer; then inspect standards or statutes for confirmation.
Discusses digitisation of land records under a central programme, illustrating a general pattern that digitised official records are designed to improve accessibility and traceability of ownership/issuance.
A student might infer that digital signatures, as part of digitised official workflows, are likely to include traceable issuer information and then consult relevant technical/legal specifications.
- Explicitly lists 'digital signature' alongside digital verification (e-KYC) and other digital public goods, linking it to identity-related digital infrastructure.
- Connects digital signature/verification to improved access to formal services and trust-based governance, implying an authentication role online.
- Describes Aadhaar as a tool for identity mapping with a centralized database and a unique identity number used to access services.
- Provides an example of a digital identity system that is used to authenticate individuals for access to services, analogous to authentication functions of digital signatures.
- Describes the Internet as the primary medium for accessing information and carrying out transactions, the context where digital authentication is applied.
- Implies a need for secure mechanisms to access online information and services, which motivates use of digital verification tools.
- Explicitly defines a digital signature as an electronic method of signing an electronic document.
- Directly contrasts digital signature (method of signing) with a digital signature certificate, confirming the signing role.
- States that a digital signature only authenticates if the signed document is unchanged, linking signatures to integrity.
- Notes that authenticated digital signatures provide cryptographic proof that an entity signed a document and that it hasn't been altered.
- Defines a digital signature as proving who signed the document (signing function).
- Clearly confirms that it also confirms the document hasnβt been altered since it was signed (integrity function).
Describes VVPAT as a paper record that lets voters verify that an electronic vote was cast correctly β showing electronic systems can include mechanisms to verify integrity of electronic records.
A student could infer that electronic systems often include verification/back-up mechanisms and therefore seek whether digital signatures serve a similar verification role for documents.
Explains the e-way bill as a digital interface replacing a physical document to ensure compliance and to track movement β an example of digitized documents serving legal/official functions.
One can extend this to ask whether digital records used for legal compliance (like e-way bills) require mechanisms (e.g., signatures) to guarantee authenticity and unaltered content.
Discusses digitization of land records reducing fraud and removing need for physical authentication β implying digital records need alternate means to establish authenticity.
A student might reason that to prevent fraud in digitized records, an electronic signing/verification tool (such as a digital signature) would be needed to ensure documents aren't altered.
Notes transactions occurring in electronic form (digital money, UPI, net banking) β showing increasing use of electronic methods in place of physical instruments.
From this pattern, one could look for electronic equivalents of traditional safeguards (signatures) for documents and transactions, suggesting a role for digital signatures.
Defines cyberspace as the electronic computerized world for communicating and accessing information β establishing the domain where electronic signing and verification would operate.
A student could use this to frame the question: within cyberspace, what technical methods (e.g., digital signatures) are used to guarantee authenticity and integrity of electronic documents?
- [THE VERDICT]: Trap (Terminological Swap). Statement 1 defines a 'Digital Certificate', not a 'Digital Signature'.
- [THE CONCEPTUAL TRIGGER]: Science & Tech > ICT > Public Key Infrastructure (PKI) & IT Act, 2000.
- [THE HORIZONTAL EXPANSION]: 1. Asymmetric Crypto (Private Key signs, Public Key verifies). 2. Role of CCA (Controller of Certifying Authorities). 3. Electronic Signature vs. Digital Signature (Legal distinction in India). 4. Hashing (ensures integrity). 5. Non-repudiation (signer cannot deny).
- [THE STRATEGIC METACOGNITION]: When studying tech terms, distinguish the 'Container' from the 'Content'. The USB token is the Container (Certificate); the mathematical encryption applied to the document is the Content (Signature).
Digital signature is named alongside e-KYC, Digilocker and UPI as a component of digital public infrastructure.

The 'Root Certifying Authority of India' (RCAI) is operated by the CCA (Controller of Certifying Authorities). While CAs issue certificates to public, the CCA regulates the CAs. This hierarchy is a potential future statement.
Apply the 'Noun vs. Verb' test. Statement 1 calls a signature an 'electronic record'. A signature is an 'act' or 'method' (Statement 3) applied TO a record. The 'record' that identifies the issuer is an ID card (Certificate). This category mismatch eliminates Statement 1.
Mains GS-2 (e-Governance): Digital Signatures provide 'Non-repudiation'. This is the legal backbone of initiatives like e-Office and GeM (Government e-Marketplace), ensuring officials cannot deny approving a file later.
