compelled by police authorities or investigative tribunals to unlock an encrypted electronic device, either by disclosing a knowledge-based passcode or by submitting to forced biometric authentication such as fingerprint recognition or facial scanning?<\/p>\n\n\n\n<h2 id=\"h-constitutional-conflict-between-investigation-and-digital-privacy\" class=\"wp-block-heading\"><span class=\"ez-toc-section\"

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This contentious doctrine sits squarely at the crossroads of the non-incrimination guarantee enshrined in Article 20(3) of the Constitution of India\u00b9 and the elevated right to informational privacy recognised as an intrinsic component of personal liberty under Article 21.\u00b2<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">While statutory provisions under the newly enacted Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) and the legacy Code of Criminal Procedure, 1973 (CrPC) confer sweeping search and seizure powers upon investigating officers,\u00b3 such statutory mandates are strictly subordinate to non-negotiable constitutional safeguards.<\/p>\n\n\n\n<h2

This paper submits that such a distinction is functionally untenable and legally arbitrary in the context of modern encryption standards.<\/p>\n\n\n\n<h3 id=\"h-identical-cryptographic-function\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Identical_Cryptographic_Function\"><\/span>Identical Cryptographic Function<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In software architecture, a passcode and a registered biometric template perform the identical cryptographic purpose: they unlock access to symmetric key storage mechanisms within the hardware&#8217;s secure enclave (such as Apple&#8217;s Secure Enclave or Android&#8217;s Trusted Execution Environment).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Treating biometrics as physical evidence while treating passcodes as testimonial mind-content ignores the reality that biometric authentication is simply a user-convenience wrapper over an underlying cryptographic master key.<\/p>\n\n\n\n<h3 id=\"h-legal-consequences-of-compelled-biometric-unlock\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Legal_Consequences_of_Compelled_Biometric_Unlock\"><\/span>Legal Consequences of Compelled Biometric Unlock<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Furthermore, forcibly compelling a biometric unlock forces the accused person to perform an affirmative act that establishes two vital incriminating legal facts that the prosecution is otherwise burdened to prove independently:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Exclusive Possession and Control:<\/strong> The successful decryption of the device via the accused&#8217;s fingerprint or face immediately proves that the accused exercises exclusive control and dominion over the device and its internal data repositories.<\/li>\n\n\n\n<li><strong>Authentication of Stored Records:<\/strong> The compelled unlock directly links the physical persona of the accused to specific files, messaging threads, and metadata contained within the device, relieving the prosecution of proving file authorship or device ownership.<\/li>\n<\/ul>\n\n\n\n<h3 id=\"h-constitutional-implications\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Constitutional_Implications\"><\/span>Constitutional Implications<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, compelling a biometric device unlock is far from a passive bodily inspection like taking a blood sample; it is an forced act of self-authentication that supplies a crucial link in the chain of incriminating evidence, directly offending the core mandate of Article 20(3).<\/p>\n\n\n\n<h2 id=\"h-key-takeaways\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Key_Takeaways\"><\/span>Key Takeaways<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Indian courts remain divided on whether compelled digital device access violates Article 20(3).<\/li>\n\n\n\n<li><em>Virendra Khanna<\/em> treats compelled unlocking as a procedural investigative step rather than testimonial compulsion.<\/li>\n\n\n\n<li>Critics argue the judgment conflicts with established Supreme Court precedent and misunderstands modern digital technology.<\/li>\n\n\n\n<li><em>CBI v.
