As Smart Glasses Gain Popularity, Privacy and Surveillance Concerns Rise

Smart glasses are rapidly transitioning from niche novelty gadgets to mainstream consumer technology, combining cameras, speakers, and artificial intelligence assistants into a hands-free form factor. However, as these devices grow in popularity, their ability to discretely record individuals who are not wearing them is sparking concerns over consent, surveillance, and privacy limits in public spaces.

Shaili Lodariya, a public relations professional from Gujarat, noted that discovering she had been recorded without consent felt deeply invasive. She pointed out that while tech-literate individuals might spot recording indicators, children and elderly people often miss the tiny lights, making them vulnerable to unconsented capture.

The issue is also surfacing at the street level. In Bengaluru, an activist group named St. Broseph issued a public service announcement warning about reports of men wearing camera-equipped glasses in crowded areas, engaging people in conversation and allegedly recording the interactions without their knowledge.

Industry experts emphasize that the problem extends beyond the visibility of indicator lights. Once footage is captured, questions arise regarding data storage, AI analysis, facial identification, and behavioral profiling. Atul Rai, CEO and co-founder of Staqu Technologies, stated that the technology industry has approached privacy reactively, prioritizing consumer excitement, hardware improvements, and smaller form factors over safeguards.

Siddhant Aggarwal, founder of Luxid Tech, argued that unrestricted visual capture should not be treated as an inevitable feature of augmented reality devices. He explained that intrusive surveillance begins when devices capture identifiable people or private spaces without consent, particularly when footage is transmitted for AI training.

Legal experts are also examining whether existing frameworks are adequate to address continuous, discrete visual capture. Lagna Panda, a partner at AP and Partners, noted that smart-glass recording can sometimes be treated similarly to mobile phone cameras under the personal-use exemption of India's Digital Personal Data Protection (DPDP) Act. However, she added that recordings processed for AI raise distinct regulatory questions depending on how they are obtained and used.

Aggarwal noted that while frameworks like the GDPR and India's DPDP Act provide baseline principles on consent and data minimisation, wearable cameras present significant practical enforcement challenges. He suggested that clearer sector-specific guidance, mandatory recording indicators, and stricter rules on human review of user-generated video would strengthen the regulatory regime.

Technology companies could mitigate these risks through product design rather than relying solely on post-deployment privacy policies. Rai advocated for on-device video processing, limited data retention, and strict controls over facial recognition capabilities. He advised engineering teams to question whether captured information needs to leave the device and to actively test how features could potentially be misused as stalking or identification tools.

Aggarwal similarly recommended that cameras should default to an off state or require clear, visible activation indicators, with data remaining local or under enterprise control wherever possible.

"The mainstream adoption of smart glasses presents a critical design and compliance challenge for the technology sector. As hardware becomes more discreet, hardware manufacturers and software developers must prioritize privacy-by-design principles, such as local data processing and clear activation indicators. Businesses operating in the wearable technology space need to address bystander consent proactively to build long-term consumer trust and navigate emerging data protection regulations effectively." — Dr. Shishir Gupta, Founder & CEO, StartupLanes
