Why are third parties are not using bitcoin biockchian or blockchain to store customers data?
If they use it to store customers data, information will not be leaked? Like bitcoin I assumed YES.
Or are the third parties affraid because they want to be always centralized?
What is the remedy to customer data leakage?
1. It's expensive and frowned upon. There are actual data storage networks anyway and blockchains like storj.
Internal blockchains may be useful but you only really need a mirror system (RAiD0).
2. Data is publicly accessible on the blockchain, therefore theyd have to encrypt this information before it is stored and what encryption do you use to publicly broadcast secret information so it's not decryptable (the short answer is you don't broadcast it because you can't gaurentee this)?
3. This has nothing to do with companies wanting to be centralised, because they don't. Facebook store information for most worldwide customers in at least 3 different places - although there are areas like Europe where data has to be stored locally so local backups will occur in the same place).
4. Get better security. Properly encrypt stuff and don't store unnecessary data online (even if it's not pii).
