Algorithm 2 Ring Signature and Public Key Sharing.

1:functionSignature ($data\_file$) 2:    if user chose anonymity over blockchain then 3:        Generate an asymmetric public-private key pair $s{k}_{s_{pub}},s{k}_{s_{priv}}$ 4:        $has{h}_p\leftarrow$ calculate hash of the $data\_file$ 5:        Create the Digital Signature using $has{h}_p$ and signers private key $s{k}_{s_{priv}}$ 6:        Share the public key $s{k}_{s_{pub}}$ to the receiver using Diffie–Hellman key exchange 7:        Mix the signature with another network group to form a ring 8:    end if 9:end function
