1. A method comprising:
creating a first group of users by computing first transform keys from the first group of users to each user in the first group of users;
enabling the users in the first group of users to access data of a first user by computing a second transform key from the first user to the first group of users;
creating a second group of users by computing third transform keys from the second group of users to each user in the second group of users;
enabling the users in the second group of users to access the data of the first user by computing a fourth transform key from the first user to the second group of users; and then
disabling the users in the first group of users from accessing the data of the first user by removing the second transform key;
wherein the second transform key constitutes a transform from a private key of the first user to a public key of the first group of users.
