Limiting access to a digital item
Abstract:
In a method for limiting access to a digital item, a count for the digital item is stored, wherein the count is a number of accesses permitted for the digital item. A password for accessing the digital item is received. A one-way hash function is performed on the password based on the number of accesses of the count to generate a password hash based on the count. The password hash is stored as the stored password hash.
