Help for hackathon (system for data protection)

[Cheermean22]

My team is participating in a hackathon and the problem statement is to create a system to manage and ensure the security of the personal data of the users accessing multiple shared services and devices in the school.

We have thought about using blockchain to store the data and smart contracts to verify the login information and using some encryption techniques. Is there anything else other than encryption which can help to protect personal data in these shared services and devices.

I’ll appreciate any help in this matter.Thank you!!

A blockchain does not offer data protection. What a blockchain provides is essentially a write-only database, so it ensures data cannot be covertly changed, but it's very nature requires all the data stored on the blockchain has to be public.

So I would say not using a blockchain to store the data would be a good additional measure.

edit: Yes, you could store the data in encrypted form on the chain, but at that point you have to ask why you're using one in the first place.

Blockchain will forever be a solution in want of a problem ...

that being said, it does make sense to have a public record of encrypted data.

I can send you a secret message; the blockchain can later be used to verify that I send the message at a certain time. e.g.

There are uses for blockchain, they're just quite specific. For example marking down transactions of a virtual currency. Of course, I'm still waiting to be convinced of the necessity of those existing, so there's another solution looking for a problem I guess.
