    "abstract": "Sealing information means making it publicly available, but with the\npossibility of knowing if it has been read. Commenting on [1], we will show\nthat perfect quantum sealing is not possible for perfectly retrievable\ninformation, due to the possibility of performing a perfect measurement without\ndisturbance, even on unknown states. The measurement is a collective one, and\nthis makes the protocol of quantum sealing very interesting as the only example\nof the power of collective measurements in breaking security.",
