  • the second method utilizes encryption. After the server computer receives the consumer' s unique machine and/or software identification code, the music is encrypted. The server first generates an encryption/decryption algorithm that is unique to the consumer' s machine and/or software identification codes. The music may then be compressed. After compression, the music is encrypted in stage 915 using the unique machine and/or software identification code. In some embodiments, the encryption ' is performed at a few select locations in the recording to reduce the amount of time required to decrypt the music. Since the music must be decrypted each time the music is played, limiting the amount of decryption necessary allows optimal playback on average and low-end computer systems.

Stage 940 then compares the extracted identification code with the unique machine and/or software identification code embedded in the consumer's music player software/hardware. If the identification codes are the same, the music player proceeds to decrypting (stage 955) and playing (stage 960) the recording. If the identification codes are not the same, the music player may issue a prompt in stage 945 to the consumer to input the unique machine and/or software identification code that is embedded in the music.
