We combine an FDA approved DNA kit with NuChyper and Blockchain to enable an anonymous and encrypted way to interact with the World’s Genomic ecosystem with privacy & control.

Suppose Bob is uploader and Alice is DNA consumer:

First Bob will create an account by providing the email (Used only for communication purpose for now) and password (a password for generating the blockchain address).

Now bob will get the following values and needs only the accountAddress and password for using the platform services.

accountAddress (Ethereum address) publicKey (Nucypher public key) privateKey (Nucypher private key) Now Bob will upload the data by filling the folloing values (Since system is anonymous there is no login and all)

accountAddress password publicKey privateKey detail about the DNA file (blob) Once bob uploads the data. It will be encrypyted and hosted to IPFS. For encryption Bob’s (publicKey, privateKey) will be used and following will be generated

capsule (capsule object which be stored against a capsuleId[uuid]) ciphettext Now these two values (capsuleId, ciphertext) will stored on blockchain by calling our solidty contract and transaction hash will be generated.

Bob will get the capsuleId (aka salivaId) and transactionHash of the blockchain transaction

The capsuleId and deatils of DNA data (like whose DNA is this and all) will be visible to everyone.

Suppose alice wants to access the DNA data after looking and DNA details

Now alice will create an account by providing the email (Used only for communication purpose for now) and password (a password for generating the blockchain address).

Alice will create a “Request access” by providing the following details

accountAddress (alice’s) Nucypher publicKey (alice’s) for creating the policy where kfrags are attached capsuleId password (alice’s) A mail will be sent to Bob’s email address for the consent. Bob can give his consent by clicking the link in email.

Once bob give the concent a policyId will be generated and for Alice and alice will get an email containing a secret code to access the policyId and transaction will be made on blockchain with following values

policyId capsuleId pubKey singingPubKey Now alice will go to the “decode page” and paste the received secret code.

Upon decode request the kfrags will be extracted and attached to the capsule (fetched from capsule map using capsuleId). And decrypted IPFS file link will be shared with the Alice
