Quantum error correcting code is a useful tool to combat noise in quantum computation. It is also an important ingredient in a number of unconditionally secure quantum key distribution schemes. Here, I am going to show that quantum code can also be used to seal a quantum message. Specifically, every one can still read the content of the sealed quantum message. But, any such attempt can be detected by an authorized verifier with an exponentially close to one probability
