Abstract:
1. A computer-implemented method for limiting access to a digital item, the method comprising: storing a count for the digital item in an access count file by a computer, where the count is a number of accesses permitted for the digital item by a user; receiving a password of the user for accessing the digital item by the computer; performing a one-way hash function by the computer on the password based on the number of accesses of the count, to generate a password hash based on the count; storing the password hash as a stored password hash by the computer; receiving a request to access the digital item at the computer, the request comprising the password; accessing the count for the digital item by the computer from the access count file; performing the one-way hash function on the password based on the number of accesses of the count, to generate an access password hash based on the count; validating the request by comparing the stored password hash to the access password hash, provided the stored password hash matches the access password hash, granting access to the digital item; and decrementing the count and updating the stored password hash.
