Decentralized information protection for confidentiality and tamper-proofing on distributed database

One or more non-transitory computer-readable storage media storing one or more sequences of program instructions which, when executed by one or more computing devices, cause:

• using a first computing device, generating a plurality of encrypted shares from a plurality of shares of hidden security service data by using a separate public key from a plurality of public keys that correspond to a plurality of second computing devices;
• using a requesting second computing device, accessing and decrypting a first encrypted share of the plurality of encrypted shares using a first private key corresponding to the requesting second computing device to generate a first portion of the hidden security service data;
• using an available second computing device, decrypting a second encrypted share of the plurality of encrypted shares using a second private key corresponding to the available second computing device to generate a decrypted share;
• using the available second computing device, re-encrypting the decrypted share using a public key corresponding to the requesting second computing device to generate a re-encrypted share and sending the re-encrypted share to the requesting second computing device;
• using the requesting second computing device, decrypting the re-encrypted share using the first private key to generate a second portion of the hidden security service data;
• using the first portion and second portion of the hidden security service data, forming and using a readable copy of the hidden security service data to perform authentications.

A computer system providing an improvement in data security, the system comprising:

• a distributed blockchain data repository;
• a first computing device that is communicatively coupled to the distributed blockchain data repository and comprising a first non-transitory data storage medium storing instructions which, when executed by the first computing device, cause:
• generating a plurality of encrypted shares from a plurality of shares of hidden security service data by using a separate public key from a plurality of public keys that correspond to a plurality of second computing devices;
• at least two second computing devices of the plurality of second computing devices that are communicatively coupled to the distributed blockchain data repository and each comprising a second non-transitory data storage medium, storing instructions which, when executed by the plurality of second computing devices, cause:
• using a requesting second computing device, accessing and decrypting a first encrypted share of the plurality of encrypted shares using a first private key corresponding to the requesting second computing device to generate a first portion of the hidden security service data;
• using an available second computing device, decrypting a second encrypted share of the plurality of encrypted shares using a second private key corresponding to the available second computing device to generate a decrypted share;
• using the available second computing device, re-encrypting the decrypted share using a public key corresponding to the requesting second computing device to generate a re-encrypted share and sending the re-encrypted share to the requesting second computing device;
• using the requesting second computing device, decrypting the re-encrypted share using the first private key to generate a second portion of the hidden security service data;
• using the first portion and second portion of the hidden security service data, forming and using a readable copy of the hidden security service data to perform authentications.
