Professional Ethics and Cyber Law
— Unit - 3 —
1. The Information Technology Act, 2000
Before the year 2000, India had no legislation to deal with cybercrimes or electronic commerce. If someone stole data or sent a forged email, police had to forcefully map these actions to physical laws in the Indian Penal Code (IPC) designed in 1860, which often failed in court.
The IT Act, 2000 was enacted based on the UNCITRAL Model Law. It serves two massive purposes:
E-Commerce Facilitation: It grants legal recognition to electronic records and digital signatures, making online banking, e-contracts, and e-governance legally valid.
Cybercrime Prosecution: It defines specific cyber offences and their penalties.

2. The IT (Amendment) Act, 2008
Technology evolved rapidly. By 2008, smartphones, social media, and broadband gave rise to new threats like cyber terrorism, voyeurism, and identity theft. The 2008 amendment drastically expanded the scope of the Act.
⇒2.1 Section 66A Controversy
The 2008 amendment introduced Section 66A, penalizing the sending of 'offensive' messages through communication services. It was heavily criticized for being overly broad and violating the fundamental right to free speech (Article 19). In a landmark 2015 judgment (Shreya Singhal v. Union of India), the Supreme Court of India struck down Section 66A entirely as unconstitutional.

5. Obscenity and Intermediary Liability
⇒5.1 Publishing Obscene Material (Section 67)
Publishing or transmitting material in electronic form which is lascivious or appeals to the prurient interest. Section 67A specifically targets sexually explicit acts, and 67B targets child pornography.
⇒5.2 Safe Harbor for Intermediaries (Section 79)
If a user posts defamatory or illegal content on Facebook, is Facebook legally liable? Section 79 provides a 'Safe Harbor'. An intermediary (ISP, social media platform) is not liable for third-party data hosted by them IF they merely act as a conduit, observe due diligence, and expeditiously remove the content upon receiving a court or government order.

6. Unit Summary and Exam Priorities
This unit requires rote memorization of the IT Act Sections.
Section 43 vs 66: Understand that 43 is civil (paying damages for hacking) and 66 is criminal (going to jail for hacking with fraudulent intent).
Specific Crimes: Memorize Sections 66C (Identity Theft), 66D (Phishing), and 66F (Cyber Terrorism). Examiners frequently ask 'Under which section is Phishing penalized?'
Safe Harbor (Sec 79): Highly relevant for modern tech platforms. Understand the conditions under which an ISP or platform is protected from the crimes committed by its users.
