Write a simple protocol that allows a client to privately retrieve the i

th record of the database. Now, assume that one of the servers is malicious and can tamper with the database. Would the above protocol still

work? Why$/$Why not? Now, Modify the above protocol so that we can detect any foul play from the malicious database holder. $($Hint: Along

with the shares of a standard basis vector the client sends the shares of a standard$-$basis vector scaled with a random

$\backslash$alpha $.).$ Prove the correctness.
