A recognition system which obtains and analyzes images of at least one object in a scene comprising a wide field of view (WFOV) imager which is used to capture an image of the scene and to locate the object and a narrow field of view (NFOV) imager which is responsive to the location information provided by the WFOV imager and which is used to capture an image of the object, the image of the object having a higher resolution than the image captured by the WFOV imager is disclosed. In one embodiment, a system that obtains and analyzes images of the irises of eyes of a human or animal in an image with little or no active involvement by the human or animal is disclosed. A method for obtaining and analyzing images of at least one object in a scene comprising capturing a wide field of view image of the object to locate the object in the scene; and then using a narrow field of view imager responsive to the location information provided in the capturing step to obtain higher resolution image of the object is also disclosed.

A system as claimed in claim 1 in which the access control unit is incorporated in a discrete module insertable in the recording device to permit decryption and descrambling of the recorded data upon playback. 3. A system as claimed in claim 1 further comprising a separate receiver/decoder adapted to receive the transmitted digital data and encrypted code word and to communicate this information to the recording device for subsequent recordal. 4. A system as claimed in claim 1 in which the transmission means is adapted to repetitively transmit the scrambled digital data and encrypted code word. 5. A system as claimed in claim 1 in which the control word for the data is encrypted by a first key associated with the identity of the data being transmitted. 6. A system as claimed in claim 5 in which the first key is encrypted by a second key before communication to the access control unit. 7. A system as claimed in claim 5 further comprising a key encryption apparatus adapted to encrypt the equivalent first key by a second key before communication to recording device, the access control unit possessing an equivalent of the second key so as to permit the decryption of the first key and, thereafter, the decryption of the control word and subsequent descrambling of the transmitted data. 8. A system as claimed in claim 7, further comprising a receiver/decoder unit adapted to request a first key from the key encryption apparatus, the key encryption apparatus thereafter communicating the encrypted first key to the receiver/decoder for subsequent communication to the recording device and access control module. 9. A system as claimed in claim 1, the access control module comprising a credit unit for controlling the number of times a recording is played. 10. A system as claimed in claim 1 in which the same first key is used to encrypt the control word or words associated with a plurality of sets of data. 11. A system as claimed in claim 1 in which the first key is repetitively transmitted by the transmission means in a message encrypted by a second key. 12. A system as claimed in claim 11, in which the message sent by the transmission means containing the encrypted first key also contains credit information intended for a credit unit within the access control module. 13. A system as claimed in claim 1 in which the transmission means responds to a real-time request to transmit the scrambled digital data and encrypted control word. 14. A system as claimed in claim 13 in which the control word is directly encrypted by a first key associated with the identity of the access control unit, the access control unit possessing an equivalent of the key to permit the decryption of the control word and subsequent descrambling of the data. 15. A system as claimed in claim 1 in which the transmission means is adapted to transmit audio data. 16. A system as claimed in claim 15 in which the recording device comprises a mini disc recorder adapted to include access control means. 17. A recording device for use in the system as claimed in claim 1, adapted to record scrambled data and an associated encrypted control word and comprising an access control means adapted to decrypt the recorded control word and descramble data upon playback. 18. A system for transmission and recording of di
