Abstract:
A method for the decryption of an incoming encrypted signal sequence, wherein encryption can be performed through inserting analog identification signals prior to, in between, and/or after a partitioned analog signal segments, said method preclude encryption by rearrangement of sequential order, said method directing incoming encrypted signal sequence for decryption through deletion of all identification signals and determining and locating the identification signals within said incoming encrypted signal sequence through recognizing those signal segments which can conform with or satisfy digital representation requirement, comprising the following steps:(i) storing or receiving digital representation requirement;(ii) receiving an incoming encrypted signal sequence;(iii) determining and locating single or plurality of identification signals within said incoming encrypted signal sequence through recognizing those signal segments which can conform with or satisfy said digital representation requirement;and(iv) directing said incoming encrypted signal sequence for decryption through deletion of all identification signals without rearrangement of sequential order, and reconstruction of said incoming signal sequence to its original form.
