Balancing Security and Privacy in Residential Societies: An Expert Opinion

By Amit Khetariya — 2026-08-10

In our view, security and privacy in housing societies are not opposites.

In short: in our view, security and privacy in housing societies are not opposites. Good security records only what it needs, shows it only to those who need it and keeps it only as long as needed. This article looks at current practices, the privacy concerns they raise, how to find the balance, technology's role, an example, common mistakes and how to build a privacy-conscious security plan.

What do current security practices look like?

• Visitor registers with names, phone numbers and sometimes ID numbers.
• CCTV in common areas.
• Records of domestic workers, sometimes with ID copies.
• Gate logs of residents' comings and goings.
• WhatsApp groups where residents share photos of "suspicious" people.

What privacy concerns do they raise?

• Full Aadhaar or licence numbers written in open registers.
• Visitor logs anyone at the gate can read.
• Photos of people shared widely without cause.
• Data kept for years with no purpose.
• Residents' movements visible to staff who don't need them.

Finding the balance: our view

1. Collect less: record what security actually needs.
2. Restrict access: show records only to people whose role requires it.
3. Keep data for a purpose: remove what is no longer needed.
4. Be open: tell residents, staff and visitors what is recorded and why.
5. Follow the law: the DPDP Act, 2023 sets out consent, purpose and retention duties.

How can technology help harmonise security and privacy?

• Partial ID storage: myKutir stores only the last four characters of an ID number, never the full number.
• Role-based access: guards see what the gate needs, and the committee sees more.
• Private incident register: guard reports about suspicious people are seen by the committee, not residents.
• Opt-in family alerts: families choose which members' gate exits they want to hear about.
• Consent for face data: regular staff are enrolled for face recognition with their consent.

Case study

An illustrative example. A 350-flat society replaced its open visitor register, which listed full ID numbers, with a digital system storing only the last four characters. Suspicious-person reports moved from the residents' WhatsApp group to the guard incident register. Security improved, because records were complete and searchable, while far less personal data was exposed.

Common mistakes to avoid

• Photocopying ID cards of every visitor.
• Sharing CCTV stills in resident groups.
• Shared logins for gate devices.
• Keeping records of former staff and residents indefinitely.

Creating a privacy-conscious security plan

1. List what security data you collect and why.
2. Stop collecting anything without a clear purpose.
3. Set access by role.
4. Decide how long each record is kept.
5. Publish a short privacy note for residents, staff and visitors.
6. Review the plan once a year.

Frequently asked questions

Do we need full ID numbers for visitors?

Usually not. Recording the ID type and last four characters is enough to identify a visitor later if needed.

Who should see the visitor log?

Security staff and the committee, as their roles require. Residents see visitors to their own flat.

Key takeaways

• Security and privacy can work together.
• Collect less, restrict access and keep data only for a purpose.
• Store partial IDs and keep incident reports private.
• Follow the DPDP Act, 2023.
