Abstract:
1. A system for secure communication across a communication network comprising: a personal code generation means having an identification code and an encryption code, the identification code and the encryption code being arranged to change randomly at predetermined intervals of time; and a code server including the identification code and the encryption code, the code server being synchronised with the personal code generation means such that the identification code of the code server and the encryption code of the code server change independently of and in synchronisation with the identification code of the personal code generation means and the encryption code of the personal code generation means respectively, such that the code server is able to independently determine the identification code and the encryption code of the personal code generation means at any instant of time; wherein, in use, a user transmits across the communication network, only the identification code of the personal code generation means together with data encrypted with the current encryption code of the personal code generation means and wherein the code server matches the identification code of the personal code generation means with the corresponding identification code of the code server to authenticate the user and uses the corresponding encryption code in the code server to decrypt the transmitted data.
