Abstract:
1. A method of securing stored data on a computer system, the method comprising: receiving one of several different password data at the computer system; transforming key data with one of the several different password data in a reversible fashion to produce encoded key data such that the one of the several different password data is required in order to perform a reverse transform and extract the key data from the encoded key data; and storing the encoded key data such that the one of the several different password data and one of a plurality of user authorization processes, in combination, provide access to the key data, wherein the key data is encoded with each of the several different password data to provide different encoded key data for each user authorization process such that a combination of one of the user authorization processes and a respective password data of the several different password data allows for retrieval and decoding of the key data, and wherein the key data is for performing at least one of encrypting and decrypting the stored data on the computer system.
