Abstract: A system for providing security for a personal password during an authentication process. The system combines the use of representative characters to disguise the characters of the password and the use of a separate verification code sent to the user for use in the authentication process. A server generates and sends both a set of representative characters and a verification code to a client device. The user then inputs a mixed string having the password and verification code interspersed in order using the representative characters in place of the characters of the password and verification code. The server then receives the input and determines whether the string of representative characters includes the password and verification code characters in the proper order.

Abstract: A system and method for modifying material related to computer software. The system receives an original disclosure for a software system. A masquerading algorithm is applied to the original disclosure to generate a new disclosure. The subject matter of the new disclosure is different from the original disclosure but has the same functionality. The system also receives original source code for the software system and applies a camouflaging algorithm to the original source code to generate modified source code and conversion data for converting between the modified source code and the original source code.
