Thank you for participating in the Samsung Developer Forum. However, this is not the correct forum for end concerns. I would recommend you post at https://www.samsung.com -> Click on Explore Tab -> Click on Community.
Not because of your accusation but because end user questions disrupt developer discussion this thread will be removed soon, but I’ll leave it open for a short time in case others wish to explain how a blockchain Keystore works.
