Because of limited server and network capacities for streaming applications, multimedia proxies are commonly used to cache multimedia objects such that, by accessing nearby proxies, clients can enjoy a smaller start-up latency and receive a better quality-of-service (QoS) guarantee-for example, reduced packet loss and delay jitters for their requests. However, the use of multimedia proxies increases the risk that multimedia data are exposed to unauthorized access by intruders. In this paper, we present a framework for implementing a secure multimedia proxy system for audio and video streaming applications. The framework employs a notion of asymmetric reversible parametric sequence (ARPS) to provide the following security properties: i) data confidentiality during transmission, ii) end-to-end data confidentiality, iii) data confidentiality against proxy intruders, and iv) data confidentiality against member collusion. Our framework is grounded on a multikey RSA technique such that system resilience against attacks is provably strong given standard computability assumptions. One important feature of our proposed scheme is that clients only need to perform a single decryption operation to recover the original data even though the data packets may have been encrypted by multiple proxies along the delivery path. We also propose the use of a set of encryption configuration parameters (ECP) to trade off proxy encryption throughput against the presentation quality of audio/video obtained by unauthorized parties. Implementation results show that we can simultaneously achieve high encryption throughput and extremely low video quality (in terms of peak signal-to-noise ratio and visual quality of decoded video frames) for unauthorized access.

A simple Google search and you'll find dozens of really good PHP scripts on the Internet to help you create proxy servers in minutes for free. The only limitation with PHP based proxies is that you require a web server to host the proxy scripts and second, you also need a domain name to act as an address for your proxy site.
If you don't own a domain or server space, you can still create a personal proxy server for free and that too without requiring any technical knowledge.

Create a Free Proxy Server with Google App Engine Here's one such proxy site that you can build for your friends in China or even for your personal use (say for accessing blocked sites from office). This is created using Google App Engine and, contrary to what you assume, the process is quite simple.
Step 1: Go to and sign-in using your Google Account.
Step 2: Click the "Create an Application" button. Since this is your first time, Google will send a verification code via SMS to your mobile phone number. Type the code and you're all set to create apps with Google App Engine.
Step 3: Choose a sub-domain* that will host your proxy server. Make sure the domain is available, agree to the Google Terms and click save. The sub-domain is also your App ID that will uniquely identify your proxy application.
For this example, we'll use labnol-proxy-server as the App ID though you are free to choose any other unique name.
Step 4: OK, now that we have reserved the ID, it's time to create and upload the proxy server application to Google App Engine. Go to, download the 2.6.4 MSI Installer and install Python.

Even though Java is installed in my computer, it's having issues because it can't proceed w/ the current internet connections. I tried the website instructions to fix it, but nothing worked. Now, internet...

It sounds like you activated a firewall somewhere in there. Calm down and go find out about your proxy server if you were using one in the first place.

Also, what website instructions do you think you followed, anyhow? Lots of websites, lots of've given no indication which one you chose.

How can i connect the data base during my project

That seems fine.

I cant assume your level of confidence in programming, however, following are some simple steps you can follow to achieve (for complex implementations, much more time and details will be needed, i can help u with them as well)

1. Create a database in Access ( i assume u r using Access 2003)
2. Create a System DSN (if aren't clear, how to create then goto administrative tools under control panel and you'll find Data Sources (ODBC), here u need to create System level DSN for Access driver (may be Jet 4.0+)
3. In java, you need to import java core libraries for sql (javax.sql package specially)
4. you are almost done, just google for database code in java, simple code will be around 5-10 lines (just for your reference, search with these keywords, ClassName(""), jdbc:odbc:YourDSN)
5. Open a connection using Connection object
6. Fetch the records (select query) using Recordset object
7. You're done.

How to play audio clip in java

  • Create an AudioClip object
  • Load .au sound file into AudioClip
  • Play sounds once or loop continuously
  • Stop playback

Here's how the code for these steps looks:
import java.applet.*;
AudioClip ac = getAudioClip(getCodeBase(), soundFile);; //play once
ac.stop(); //stop playing
ac.loop(); //play continuously

It would seem logical to use this same code to play audio clips in a Java application. Unfortunately, if you do that you will get errors from the compiler. Why? Because the AudioClip object and the getAudioClip() method are part of the java.applet package -- and are not part of applications. The good news is we can dive down and make things work ourselves.
The trick to solving this problem is to use some undocumented features that are provided by Sun in its JDK. Taking a peek inside the file from the Sun JDK (using any of the various zipfile utilities), we find not only the standard Java packages such as java.applet but also (These are in the directory sun/audio.)
The package contains everything we need to be able to play audio clips! Here's the code:
import*; //import the package
//** add this into your application code as appropriate
// Open an input stream to the audio file.
InputStream in = new FileInputStream(Filename);
// Create an AudioStream object from the input stream.
AudioStream as = new AudioStream(in);
// Use the static class member "player" from class AudioPlayer to play
// clip.
// Similarly, to stop the audio.

To use a URL as the audio stream source, substitute the following for the input stream and audio stream setup:
AudioStream as = new AudioStream (url.openStream());

Playing the audio stream continuously adds a bit more complexity:
// Create audio stream as discussed previously.
// Create AudioData source.
AudioData data = as.getData();
// Create ContinuousAudioDataStream.
ContinuousAudioDataStream cas = new ContinuousAudioDataStream (data);
// Play audio. (cas);
// Similarly, to stop the audio.
AudioPlayer.player.stop (cas);
