IPC: G06F12/14
Filed: 1998-07-29
Abstract: In a method for checking the authenticity of a data medium, in particular a smart card, the encrypted form of a physical feature of the data medium is stored in the data medium. The encrypted form of the feature is transmitted to a terminal, which also measures the physical feature itself. The physical feature is encrypted using a secret key, and is decrypted in the terminal using a public key. Authenticity is confirmed if a comparison of the decrypted feature and the measured feature match. Since the secret key is not contained in either the data medium or the terminal, a high level of security is provided.

Abstract: PURPOSE: A method for verifying the functions of a fax in a WLL(Wireless Local Loop) terminal is provided to simply carry out message formatting and to sufficiently verify the function without system support by connecting a local fax and a remote fax in accordance with IS-707A.7 standards in an end-to-end method using a fax emulator. CONSTITUTION: If a user inputs a fax test mode approach code "##6941*" after an off-hook at a telephone or a local fax attached to a WLL terminal(S101), the WLL terminal judges whether the fax test mode approach code has been inputted(S103). If the fax test mode approach code has been inputted, the WLL terminal disconnects an air interface(S107) and allocates a serial port to a fax processing unit(S108). The WLL terminal executes hook sensing for 10 seconds and judges whether an on-hook is detected within 10 seconds(S111). If the on-hook is not detected within 10 seconds, the WLL terminal approaches a fax processing unit hardware test mode(S115). However, in case that the on-hook is detected within 10 seconds, the WLL terminal approaches an IS-707A.7 fax call emulation mode, initializes the fax processing unit, and waits for the next event(S113).

Abstract: PURPOSE: A high density optical data storage medium is provided to enable high density write and read by forming a fine focus light having the size less than diffraction limit and maintaining the size in the range of laser power. CONSTITUTION: A high density optical data storage medium includes an incident layer(1) to which a light transmitting a lens and focused is irradiated, a first super resolution layer(3) controlling spot size of the irradiated focus light, a second super resolution layer(2) controlling spot size of the irradiated focus light, and a record layer(4) recordable optical data, wherein the first super resolution layer and the second resolution layer change the spot size of the transmitting light by changing transmittance according to power of an incident light, and change the spot size of the transmitting light complementarily because the first super resolution layer and the second resolution layer are different from each other in threshold strength starting transmittance change.
