Demonstration

Technology Apache ( mod_deflate is adoptedhttp://httpd.apache.org/ PHP ( MySQL ( amp The MP3 watermarking is based on amp, which is a Unix command line MP3 player. PayPal Instant Payment Notification (IPN) ( bin/webscr?cmd=p/xcl/rec/ipn-intro-outside) bin/webscr?cmd=p/xcl/rec/ipn-intro-outside

Compressing HTTP contents HTTP contents can be compressed using Content- Encoding 85% of web hits are text only, and compress them will reduce 71% bandwidth Currently there’re two most widely adopted modules: mod_deflate (built-in Apache2 module) mod_gzip ziped content

MP3 Streaming The MP3 streaming technology is used to serve as online trial listening The MP3 streaming is achieved with WinAmp via HTTP protocol. When receiving user’s request, the server returns a play-list with proper content-type so that the client WinAmp can handle this play-list and do the streaming work. Theoretically, only 16 KB/s bandwidth is required to hear a 128 kBits MP3 music.

MP3 Watermarking A string with 128 bytes can be embedded in each MP3 file downloaded by user We “signed” the target MP3 with user’s address, and it’s embedded real-time. If any illegal copy is found, we can check the watermark to find out who has distributed this MP3. We claim that the watermark is not easy for common end- user to remove it, and since its real-time embedding approach, we can change the algorithm frequently. And the watermarked MP3 do not need specific player, its general acceptable. User has his right to choose his player. (It’s very important since changing can be painful)

PayPal IPN Instant Payment Notification (IPN) is PayPal's interface for handling real-time purchase confirmation and server-to-server communications.

Viewpoint (1/2) In our opinion, with the IT technology growth, the traditional way of music selling in this industry should be changed to stay in profit. Apple iTune has proved that selling music online is possible. Through the dynamic property of Internet, the dynamic ranking / pricing is easy to achieve comparing to the traditional way. The content provider may have better interaction with their customers through the online community.

Viewpoint (2/2) The basic unit of music is changed from CD title to single entity and consumers have more freedom to choose. They’re not forced to buy those songs they don’t like now. Users should pay more respect for the Intellectual Property Rights (IPR related issues remain critical).

What we made? In our term project we've made an E- Commerce website with: Member system to register and update profile Payment system via PayPalR Search and browse for music content Purchase and download music content Ranking for our download hits and to include foreign rankings

What’s different? Our system is different to others with these features: Dynamic pricing, even feedback Pay once download anytime Online preview without charging Digital signature (i.e., Watermarking) System available to all W3C HTML compatible platforms Content available to all MP3 compatible players
