Claim:
A method for controlling access to text information on a device on a network, the method comprising: receiving text information at the device, the text information including one or more protected features; in response to an attempt to access the one or more protected features, generating at the device an identifier of the one or more protected features, the identifier being based at least in part on a context of the text information to which access to the one or more protected features is linked; utilizing the identifier, at the device, to validate a password accessible to the device by determining that the identifier is a result of a pseudo random number generation of a candidate seed, which is a value contained in the password, the password controlling access to the one or more protected features; enabling access to the one or more protected features if the password is validated; wherein the password is generated at a remote licensing system, and the device is configured to validate the password while also being unable to generate the password; and wherein the context of the text information is a hardware characteristic of the device.
