IT Act and Cyber Laws in India: Sections and PYQs — GK24 title card

When a contract is signed on a screen, when a bank transfer is made from a phone, when an obscene image is forwarded on a messaging app, the law that applies in India is the Information Technology Act, 2000. It is the country's principal cyber law. Before it there was no way to treat an electronic record as evidence or an electronic signature as a signature, and no offence described in terms of a computer. The Act gave electronic records legal recognition, created the machinery for digital signatures, listed the offences that can be committed with a computer, and set up the agencies that watch over the network. This note covers its history, its structure, the sections that are asked, and the other laws and agencies that sit beside it.

How the Act came about

The Information Technology Act was passed by Parliament in 2000, received assent on 9 June 2000 and came into force on 17 October 2000. It is modelled on the UNCITRAL Model Law on Electronic Commerce of 1996, which the General Assembly of the United Nations recommended to member states, so the Act's language on electronic records follows an international template. As first enacted it had 94 sections arranged in 13 chapters, with four schedules, and it also amended the Indian Penal Code, the Indian Evidence Act, the Bankers' Books Evidence Act and the Reserve Bank of India Act so that electronic records would be recognised there too.

The Act was substantially rewritten by the Information Technology (Amendment) Act, 2008, which came into force on 27 October 2009. That amendment made the law technology neutral by adding electronic signatures alongside digital signatures, inserted the whole family of computer-related offences in sections 66A to 66F and 67A to 67C, added compensation for failure to protect personal data, gave statutory footing to CERT-In and to the protection of critical information infrastructure, and recast the safe harbour available to intermediaries.

What the Act does not cover

Section 1 and the First Schedule exclude certain documents from electronic form. A negotiable instrument other than a cheque, a power of attorney, a trust deed, a will or any other testamentary disposition, and a contract for the sale or conveyance of immovable property cannot be executed electronically under this Act. This exclusion list is a favourite one-line question. Section 75 works the other way: the Act applies to an offence committed outside India as well, if the act involves a computer or network located in India.

The sections most often asked

70A and 70BNational Critical Information Infrastructure Protection Centre; CERT-In as national nodal agencyInstitutional machinery for cyber security
79Safe harbour for intermediaries that observe due diligenceExemption from liability for third party content

Section 66A and the Shreya Singhal case

Section 66A, inserted by the 2008 amendment, punished the sending of offensive or menacing messages through a communication service. In Shreya Singhal versus Union of India, decided in 2015, the Supreme Court struck the section down in its entirety as a violation of the freedom of speech and expression guaranteed by Article 19(1)(a), holding its terms to be vague and overbroad. The same judgment upheld section 69A, which permits the blocking of content, and read down section 79 so that an intermediary need act only on a court order or a government direction. Any question assuming that section 66A is still in force is testing exactly this point.

The agencies and the newer laws

CERT-In, the Indian Computer Emergency Response Team, functions under section 70B as the national nodal agency for computer security incidents and works under the Ministry of Electronics and Information Technology; it was set up in 2004 and given statutory backing in 2008. The Controller of Certifying Authorities, also under that ministry, licenses the certifying authorities that issue digital signature certificates. The Indian Cyber Crime Coordination Centre under the Ministry of Home Affairs runs the national cyber crime reporting portal and the helpline number 1930. Appeals under the Act went first to a Cyber Appellate Tribunal, whose functions were transferred to the Telecom Disputes Settlement and Appellate Tribunal by the Finance Act, 2017; an adjudicating officer under section 46 decides claims up to five crore rupees.

Two later developments complete the picture. In Justice K. S. Puttaswamy versus Union of India, decided in 2017, a nine judge bench of the Supreme Court held that the right to privacy is a fundamental right under Article 21, which is the constitutional foundation of data protection in India. The Digital Personal Data Protection Act, 2023 then created a statutory framework for the processing of digital personal data, with consent, the duties of a data fiduciary and the rights of the data principal at its centre. Rules made under the IT Act, particularly the Intermediary Guidelines and Digital Media Ethics Code Rules of 2021, govern social media platforms, grievance officers and the taking down of content.

Exam Point of View

Questions are of three kinds. First, dates and origins: 2000 for the Act, 17 October 2000 for commencement, 2008 for the amendment and the UNCITRAL Model Law as its model. Second, section numbers paired with offences: 65 for source code tampering, 66 for hacking, 66C for identity theft, 66D for personation, 66E for privacy, 66F for cyber terrorism, 67 and 67A and 67B for obscene material, 69 and 69A for interception and blocking, 70B for CERT-In and 79 for intermediary safe harbour. Third, the case law: section 66A struck down in Shreya Singhal in 2015, and privacy made a fundamental right in Puttaswamy in 2017. The standard trap is a question that assumes section 66A is still enforceable; another is swapping the two judgments, since both are recent and both concern digital rights. Banking papers add the 1930 helpline and the data protection Act of 2023.

Practice MCQs on this topic

Q1.Computer AwarenessEasy

The Information Technology Act of India came into force in which year?

  1. A.1998
  2. B.2000
  3. C.2005
  4. D.2008
Show answer
Correct answer: B. 2000

Explanation

The correct answer is B, 2000. The Information Technology Act was passed by Parliament in 2000, received assent on 9 June 2000 and came into force on 17 October 2000; it is therefore cited as the Information Technology Act, 2000. Option A is wrong because 1998 precedes the Act, though the UNCITRAL Model Law on Electronic Commerce on which it is modelled dates from 1996. Option C is wrong because 2005 is the year of the Right to Information Act, which is often confused with it in lists of early twenty-first century legislation. Option D is wrong because 2008 is the year of the Information Technology (Amendment) Act, which substantially rewrote the parent Act and came into force on 27 October 2009; that amendment year is the commonest distractor in this question.

Q2.Computer AwarenessMedium

Section 66A of the Information Technology Act was struck down by the Supreme Court in which case?

  1. A.Shreya Singhal v. Union of India
  2. B.K. S. Puttaswamy v. Union of India
  3. C.Kesavananda Bharati v. State of Kerala
  4. D.Vishaka v. State of Rajasthan
Show answer
Correct answer: A. Shreya Singhal v. Union of India

Explanation

The correct answer is A, Shreya Singhal v. Union of India. In 2015 the Supreme Court struck down section 66A, which punished the sending of offensive messages, holding it vague and overbroad and therefore a violation of the freedom of speech and expression under Article 19(1)(a). Option B is wrong because the Puttaswamy case of 2017 declared the right to privacy a fundamental right under Article 21; it is related in subject but is a different judgment. Option C is wrong because Kesavananda Bharati, decided in 1973, laid down the basic structure doctrine. Option D is wrong because the Vishaka judgment of 1997 laid down guidelines against sexual harassment at the workplace, later replaced by legislation in 2013. Note that the same judgment upheld section 69A on the blocking of content and read down section 79, so it did not sweep away the whole chapter of offences.

Q3.Computer AwarenessMedium

Which section of the Information Technology Act, 2000 deals with the offence of cyber terrorism?

  1. A.Section 65
  2. B.Section 66E
  3. C.Section 66F
  4. D.Section 67B
Show answer
Correct answer: C. Section 66F

Explanation

The correct answer is C, section 66F. Section 66F, inserted by the amendment of 2008, defines cyber terrorism and is the most severely punished offence in the Act, carrying imprisonment which may extend to life. Option A is wrong because section 65 deals with tampering with computer source documents and carries up to three years or a fine up to two lakh rupees. Option B is wrong because section 66E punishes violation of privacy by capturing or publishing an image of a private area of a person without consent. Option D is wrong because section 67B punishes publishing or transmitting material depicting children in a sexually explicit act, the most severely punished of the obscenity provisions but not cyber terrorism. The order of sections 66A to 66F is worth memorising.

Q4.Computer AwarenessHard

CERT-In, the national nodal agency for computer security incidents, functions under which section of the Information Technology Act?

  1. A.Section 43A
  2. B.Section 69A
  3. C.Section 70B
  4. D.Section 79
Show answer
Correct answer: C. Section 70B

Explanation

The correct answer is C, section 70B. Section 70B, inserted in 2008, appoints the Indian Computer Emergency Response Team as the national nodal agency for collecting, analysing and circulating information on cyber incidents and for issuing advisories; it works under the Ministry of Electronics and Information Technology and was set up in 2004. Option A is wrong because section 43A provides compensation where a body corporate fails to protect sensitive personal data. Option B is wrong because section 69A empowers the government to block public access to information, a power upheld in the Shreya Singhal judgment. Option D is wrong because section 79 gives intermediaries a safe harbour from liability for third party content provided they observe due diligence. The Controller of Certifying Authorities, which licenses the issuers of digital signature certificates, works under the same ministry but is created by section 17.

Q5.Computer AwarenessHard

The Information Technology Act, 2000 is based on which international instrument?

  1. A.The Budapest Convention on Cybercrime
  2. B.The UNCITRAL Model Law on Electronic Commerce
  3. C.The General Data Protection Regulation
  4. D.The Berne Convention
Show answer
Correct answer: B. The UNCITRAL Model Law on Electronic Commerce

Explanation

The correct answer is B, the UNCITRAL Model Law on Electronic Commerce. The model law was adopted by the United Nations Commission on International Trade Law in 1996 and recommended to member states by the General Assembly, and India's Act follows its scheme for giving legal recognition to electronic records and signatures. Option A is wrong because the Budapest Convention on Cybercrime of 2001 is a Council of Europe treaty to which India is not a party. Option C is wrong because the General Data Protection Regulation is a European Union law of 2016 that came much later and concerns data protection, not electronic commerce. Option D is wrong because the Berne Convention of 1886 deals with copyright in literary and artistic works. The model law was adopted to let member states give electronic records the same standing as paper, and India's sections 4, 5 and 10A follow it almost directly.

Q6.Computer AwarenessMedium

Which of the following documents cannot be executed in electronic form under the Information Technology Act, 2000?

  1. A.A cheque
  2. B.An electronic mail contract for the sale of goods
  3. C.A will
  4. D.A purchase order sent online
Show answer
Correct answer: C. A will

Explanation

The correct answer is C, a will. The First Schedule to the Act excludes certain documents from electronic form: a negotiable instrument other than a cheque, a power of attorney, a trust deed, a will or other testamentary disposition, and any contract for the sale or conveyance of immovable property. Option A is wrong because a cheque is specifically carved out of the exclusion of negotiable instruments. Option B is wrong because a contract for the sale of goods may be made electronically, and section 10A expressly confirms the validity of contracts formed by electronic means. Option D is wrong for the same reason; purchase orders and similar commercial communications are exactly the transactions the Act was passed to facilitate. Section 10A, added in 2008, puts the matter beyond doubt by providing that a contract formed through electronic means is not unenforceable merely on that ground.

Q7.Computer AwarenessHard

A digital signature under the Information Technology Act is created using:

  1. A.a symmetric key and a cipher block
  2. B.an asymmetric crypto system and a hash function
  3. C.a biometric scan alone
  4. D.a one time password
Show answer
Correct answer: B. an asymmetric crypto system and a hash function

Explanation

The correct answer is B, an asymmetric crypto system and a hash function. Section 3 provides that an electronic record is authenticated by affixing a digital signature created by use of an asymmetric crypto system and a hash function; the hash function reduces the record to a message digest and the signer's private key encrypts it, while anyone can verify it with the matching public key. Option A is wrong because a symmetric system uses one shared key and cannot establish who signed. Option C is wrong because a biometric scan by itself is not what the section describes, though electronic signatures added in 2008 allow other reliable techniques. Option D is wrong because a one time password authenticates a transaction, not the record itself.

Q8.Computer AwarenessEasy

The national cyber crime helpline number for reporting financial fraud in India is:

  1. A.1930
  2. B.1098
  3. C.1800
  4. D.112
Show answer
Correct answer: A. 1930

Explanation

The correct answer is A, 1930. The helpline 1930 is run with the national cyber crime reporting portal by the Indian Cyber Crime Coordination Centre under the Ministry of Home Affairs, and is meant for the quick reporting of online financial fraud so that the transfer of money can be stopped. Option B is wrong because 1098 is Childline, the helpline for children in distress. Option C is wrong because 1800 is the prefix of toll free numbers in India and is not a helpline by itself. Option D is wrong because 112 is the single emergency response number for police, fire and ambulance services, and although a cyber complaint may be passed on from it, it is not the dedicated cyber fraud line. Complaints may also be filed on the national cyber crime reporting portal, and after the 2008 amendment an offence under the Act is investigated by an officer not below the rank of inspector.

Q9.Computer AwarenessMedium

Which amendment to the Information Technology Act inserted sections 66A to 66F and gave statutory recognition to electronic signatures?

  1. A.The amendment of 2006
  2. B.The amendment of 2008
  3. C.The amendment of 2015
  4. D.The amendment of 2021
Show answer
Correct answer: B. The amendment of 2008

Explanation

The correct answer is B, the amendment of 2008. The Information Technology (Amendment) Act, 2008 came into force on 27 October 2009 and made the most important changes to the parent Act: it added section 3A on electronic signatures, inserted the computer-related offences of sections 66A to 66F and 67A to 67C, added section 43A on compensation for failure to protect personal data, and created sections 70A and 70B. Option A is wrong because no amendment of this kind was made in 2006. Option C is wrong because 2015 is the year of the Shreya Singhal judgment, which struck down a section rather than inserting any. Option D is wrong because 2021 is the year of the Intermediary Guidelines and Digital Media Ethics Code Rules, which are rules made under the Act, not an amendment to it.

Q10.Computer AwarenessMedium

In which case did the Supreme Court hold that the right to privacy is a fundamental right under Article 21?

  1. A.Shreya Singhal v. Union of India
  2. B.K. S. Puttaswamy v. Union of India
  3. C.M. C. Mehta v. Union of India
  4. D.Maneka Gandhi v. Union of India
Show answer
Correct answer: B. K. S. Puttaswamy v. Union of India

Explanation

The correct answer is B, K. S. Puttaswamy v. Union of India. A bench of nine judges held in 2017 that the right to privacy is intrinsic to the right to life and personal liberty under Article 21, which became the constitutional basis for India's data protection framework and for the Digital Personal Data Protection Act, 2023. Option A is wrong because Shreya Singhal, decided in 2015, concerned freedom of speech and struck down section 66A of the Information Technology Act. Option C is wrong because the M. C. Mehta cases concern environmental law and the absolute liability principle. Option D is wrong because Maneka Gandhi, decided in 1978, widened the meaning of personal liberty and due process but did not declare a right to privacy.

Q11.Computer AwarenessHard

Section 79 of the Information Technology Act, 2000 relates to:

  1. A.exemption of intermediaries from liability for third party information
  2. B.punishment for identity theft
  3. C.the power to intercept and monitor information
  4. D.compensation for damage to a computer system
Show answer
Correct answer: A. exemption of intermediaries from liability for third party information

Explanation

The correct answer is A, exemption of intermediaries from liability for third party information. Section 79 gives an intermediary such as a network service provider or a social media platform a safe harbour, provided it merely transmits or hosts the content, does not initiate or modify it, and observes the due diligence prescribed by the rules; the Shreya Singhal judgment read the section down so that an intermediary need act only on a court order or a government direction. Option B is wrong because identity theft is punished by section 66C. Option C is wrong because the power to intercept, monitor and decrypt is given by section 69. Option D is wrong because compensation for damage to a computer system is provided by section 43.

Frequently Asked Questions

Is Section 66A of the IT Act still in force?

No. The Supreme Court struck it down in its entirety in Shreya Singhal v. Union of India in 2015, holding that it punished speech in vague and overbroad terms and so violated the freedom of speech and expression under Article 19(1)(a). Any case registered under section 66A after that judgment is without legal basis. The same judgment upheld section 69A, which allows the blocking of online content under a prescribed procedure, and read down section 79 so that intermediaries need act only on a court order or a government direction.

What did the 2008 amendment change?

It rewrote much of the Act and came into force on 27 October 2009. It made the law technology neutral by adding electronic signatures in section 3A alongside digital signatures, inserted the family of computer-related offences in sections 66A to 66F and 67A to 67C, added section 43A giving compensation where a company fails to protect sensitive personal data, created section 70A for critical information infrastructure and section 70B for CERT-In, added section 10A on the validity of electronic contracts, and recast the intermediary safe harbour in section 79.

Which documents cannot be executed in electronic form?

The First Schedule to the Act excludes five categories: a negotiable instrument other than a cheque, a power of attorney, a trust deed, a will or any other testamentary disposition, and any contract for the sale or conveyance of immovable property. These remain paper transactions. Everything else, including ordinary commercial contracts, purchase orders and cheques, may be in electronic form, and section 10A confirms that a contract made by electronic means is not unenforceable merely for that reason.

How does a digital signature work under the Act?

Section 3 provides that an electronic record is authenticated by a digital signature created with an asymmetric crypto system and a hash function. The hash function converts the record into a short message digest; the signer encrypts that digest with a private key known only to them, and any recipient can verify it with the corresponding public key, which is certified by a certifying authority licensed by the Controller of Certifying Authorities. Any change to the record alters the digest, so tampering is detectable.

Where is a cyber crime reported in India?

Complaints may be filed on the national cyber crime reporting portal run by the Indian Cyber Crime Coordination Centre under the Ministry of Home Affairs, and financial fraud should be reported at once on the helpline 1930 so that the movement of money can be stopped. A complaint may also be made at any police station, and after the amendment of 2008 an offence under the Act is investigated by a police officer not below the rank of inspector.
