The BIS Audio Guard is a small Java™ application based on the BIS Antidecompiler. It encrypts the audio files in the same manner as the BIS Antidecompiler encrypts Java™ classes and then compresses the encrypted audio collection into .jar file together with a tiny Java™ player. The BIS Audio Player decrypt the audio content and plays it back according to license conditions or during a trial period etc. In addition to audio content you can add an HTML page to the encrypted content. This page will be displayed with the BIS Audio Player when it will play the corresponding audio item. Thus the BIS Audio Guard prepares the protected parcel for the musical clips to send them to customers for a "preview".

 

The BIS Audio Guard 2009 is built as a wizard, and on the second screen the implementation target is selected - it may be the Audio Player for PC, i.e. simply executable jar file (multi-platform application), or files for the Mobile Devices: .jar, jad, and .wml. Depending on it the crypto method will be selected also: for the PC the standard JCE is used, and for the Mobile Devices - the crypto algorithm based on IDEA.

 

With the file dialog you can select audio files for encoding, and this dialog allows also to add comments (additionally to mp3 metatags) (author, album, title, and the like) to the audio files. This information is stored in the manifest file and is accessible for the audio player.

 

The view screen has two tabs - the audio collection content, being editable and with the possibility to add a time lock, and the second tab contains the preview of an html page attached to the adio item.

 

The preview of the attached page in the built-in browser.

 

You can save the protected jar (or jar/jad/wml) to a local directory for the further uploading, or send it directly to customer by email.

 

BIS Audio Player 2009

The Audio Player for PC plays back audio files containing in the jar. The simplest GUI provides the basic player functions, and the right pane displays the "attached" html files.

The protected audio's can be played back both on Java ME emulators and on "real" cellular phones. The audio collection "for preview" is placed on the web and can be reached via internet connection, or can be downloaded to the memory card for playing during "trial period".

N.B. The BIS Technology equally easily uses standard protocols and formats, such as TCP/IP, HTTP so others like a real time protocols - RTSP/RTP/RTCP.
