ABSTRACT:
A compact disc (10) for a computer incorporates a security device for preventing non-authorized reading of data carried by the disc. The security device includes an LCD laser blocker (16) which is activated or deactivated by means of a microchip (13) powered by a cell (14) and/or solar panel (15). Authorized reading of the data is possible by a fingerprint scanner (12) linked to the microchip and causing it to deactivate the blocker (16), when the scanner recognizes a user's fingerprint which the microchip matches to a programmed authorized fingerprint. Also disclosed is a data carrying compact disc (20) which incorporates security means to allow a first reading of the data of the disc, but to prevent such reading thereafter. An area (21) of the disc, such as a FAT file, can be arranged to be destroyed or blocked, to prevent subsequent reading thereof by the disc reading means.
