    \textrm{Slightly more formally, we define blind signatures as a quadruple 
of algorithms:}
    \begin{itemize}
      \item $ KeyGen(1^\lambda)$: Generates a verification/signing key pair 
$(K^{\pub}, K^{\priv})$.
-     \item $Blind(m,  b, K_x^{\pub})$: Takes a message $m$, blinding factor 
$b$, and verification key $K_x^{\pub}$ of the signer $X$ and computes the 
blinded message $\overline{m}$.
-     \item $BlindSign(K_x^{\priv}, \overline{m})$: Takes secret signing key 
$K_x^{\priv}$ and blinded message $\overline{m}$ and computes the blind 
signature $\overline{\sigma}$.
-     \item $Unblind(\overline{\sigma}, b, K_x^{\pub})$: Takes blind signature 
$\overline{\sigma}$, blinding factor $b$ and verification key $K_x^{\pub}$ of 
the signer $X$, and returns the unblinded signature $\sigma$ (or $\bot$).
+     \item $Blind(m,  b, K^{\pub})$: Takes a message $m$, blinding factor $b$, 
and verification key $K^{\pub}$ of the signer and computes the blinded message 
$\overline{m}$.

$K^{\priv}$ and blinded message $\overline{m}$ and computes the blind signature 
$\overline{\sigma}$.
+     \item $Unblind(\overline{\sigma}, b, K^{\pub})$: Takes blind signature 
$\overline{\sigma}$, blinding factor $b$ and verification key $K^{\pub}$ of the 
signer, and returns the unblinded signature $\sigma$ on message $m$ (or $\bot$).
