A method of accessing a shareable computer file includes receiving a request to access the shareable computer file, retrieving a file ID from a stub file corresponding to the shareable computer file, retrieving a file name from a database corresponding to the file ID, accessing the shareable computer file if a user has not modified the shareable computer file, and accessing a modified copy of the shareable file stored in the stub file if the user has modified the shareable computer file. A database is generated in operating system space or accessed using the operating system, and includes file IDs and their corresponding file names for shareable computer files. The stub file is generated locally to correspond to the shareable computer file, and includes a modified copy of the shareable computer file if the shareable computer file has been modified, and a link to the shareable computer file if the shareable computer file has not been modified. If the shareable computer file has not been modified, a read-only operation retrieves any of file contents, file position and file size from the shareable computer file. File attributes relating to the shareable computer file can be retrieved from the stub file. The database is provided by the operating system for use by a Virtual Private Server.

A method of secure biometric authentication is disclosed that shuffles arrays of biometric data in a sequence determined by user's secret input. The user is authenticated by comparing arrays of biometric data shuffled on the client side with the arrays of biometric data stored on the server side and shuffled in the very same sequence. Additional layer of security is provided by second shuffling in accordance with a number generated on the server and transmitted to the client after encoding with the user's public key / string retained on the server during enrollment. Real biometric data and sequences of shuffling are neither stored not transmitted anywhere; therefore, the privacy of the user is guaranteed. Security of the data transmitted to the server is not relevant because an attacker does not know the user's private key which is repeatedly recreated on the client from the real biometric data of the user.

Reversible and self reversing multi-value scrambling functions created by applying multi-value inverters are disclosed. The generation of possible multi-value inverters is also presented. Corresponding multi-value descrambling functions are also disclosed. The multi-value functions are used in circuits that scramble and descramble multi-value signals. The multi-value functions can also be used in signal generators. Such signal generators do not require the use of multipliers. The auto-correlation of the signals generated by the signal generators is also presented. Electronic circuits that implement the multi-value functions are also described.
