I want to create an audio-book application using Laravel.
Is it possible to protect from downloading an audio from a site ?
Is right click disable does the trick OR
What security measures will I take to prevent any audio files download ?
Meanwhile I have decided to use HTML5-Audio Player.
This question is complicated, and depending on how you deliver the audio, the answer will changes. I would recommend to look at how protected content are delivered on certain platform.
Let take a look at Spotify, they are using Widevine:
Widevine is a proprietary digital rights management (DRM) technology from Google used by the Google Chrome, Brave and Firefox web browsers (including some derivatives), Android MediaDRM, Android TV, and other consumer electronics devices.
Wikipedia
Simply disabling the download is only a frontend feature removed, that can be easily bypass. For protected content, more complicated solution are required like a DRM.

i am creating small application using webRTC and Nodejs.
After many R&D i found that webRTC seems to Work only in Chrome and Firefox and may be in opera higher versions.
and also webRTC is only technology which enables media using browser.
if is it so then what technology hangout is using , which also works well in safari?
WebRTC is already out there. Companies are using it for point-to-point and multipoint voice and video.
Google Hangout it doesn't use WebRTC, Google's VP8 codec, or even the standard H.264 codec. It uses an H.264/SVC (Scalable Video Coding) variant of it.
Google Hangouts uses Vidyo. Vidyo has a proprietary plugin which they likely re-brand for Google. I know because I had about a 1-2 hour call with Vidyo in May and they mentioned Google Hangouts among their customers.
http://info.vidyo.com/VidyoH2O-for-Google-Hangouts-ga.html
Vidyo has reasonably high priced servers which they offer for medical applications, but we needed their API which we found out was priced at $100,000+.
The conclusion: stay with WebRTC and restrict your user's browser. Safari is expected by some to offer support next year and there are signs that they are porting code from Google Chrome. http://bloggeek.me/webrtc-apple-or-microsoft/
Limited IE support is offered by various plugins if you have the time and/or money for that. ex. OpenTok
I see a lot of applications in the Mac App store, such as MiniTube and CloudPlay, which appear to stream high quality video directly from YouTube, without using any sort of embedded player.
However, I don't see any means of doing this through the documented API. Is their scraping (e.g. http://gitorious.org/minitube/minitube/blobs/master/src/video.cpp) illegal/against the TOS, or merely undocumented and unsupported? Is there a better way of doing it?
(In particular, the so-called "chromeless" iframe player actually has a significant amount of chrome/user interaction, which is more suitable for a website than for a native application.)
EDIT: I suppose my question is primarily for the official YouTube developer support: is scraping the page for the stream against the TOS? If it is, why are these apps allowed to remain on the app store, and if it isn't, what is the best way of doing so?
Never tried this, but according to this discussion here it's against the TOS to access the native streams. They also mention that you are free to access the rstp streams made for mobile devices through the api.
So I think scraping the page is the only way to get the higher quality videos without using an embedded player in your application. If you're okay with lower quality then use the rstp way.
Another discussion about the same subject.
Any scraping would violate YouTube's TOS. There are no undocumented APIs available either. For iOS the best provide option is to use the YouTube iframe embed, but that will be within a webview. For Android, YouTube is building a library to do playback without a webview. Here's a video of the announcement http://www.youtube.com/watch?v=3WFsx-u-q3Y&feature=player_embedded. It's not launched yet, but I know they've been working very hard on it and it should be available soon.
I want to make a project like the Symptoms checker like WebMD did it
WebMD Symptom Checker
i want not logged in user to interact with it.
I dont want to make it in FLASH like webmd did it, i want to make it using JQuery and Ajax,
What is the Advantages and Disadvantages of doing a project like this using Jquery and Ajax , well, i will be implementing it using Zend framework
Does Ajax Requests on a Project like this and its on a public page affect on website security ? Does it affect on SEO ? What the disadvantage for using Ajax on this project
Well I don't know what you mean exactly by advantages and disadvantages but I think you mean that you want it implemented in HTML5 instead of Flash.
Flash strengths:
Flash is more ubiquitous (most of desktop users).
The Flash developer community is large and mature.
The developer tools are strong and well supported.
Designers are more comfortable in working in flash.
The 2D and 3D APIs are more mature and usable than Canvas.
Flash gives you better access to web cam and and audio recording.
Flash better supports streaming, secure and live
video.
Flash weaknesses:
Information embedded in Flash is often invisible to search engines.
Website reporting on Flash navigation is problematic and cumbersome.
Flash breaks web usability standards.
Lack of consistent cross platform support (not all devices have the same version installed).
Code embedding Flash objects doesn’t pass w3c validation.
Some users disable Flash to avoid flash based advertising.
Website updates continually require Flash skills.
Flash breaks Search Engine Site Previews.
Flash doesn’t work well with Mac OSX, and Apple’s mobile devices do
not support Flash content.
HTML5 strengths:
Better suited for mobile devices (lower battery consumption).
HTML5 uses DOM and HTML support, so plug-ins and 3rd party programs
are unnecessary for video and audio embedding.
Websites with HTML5 elements have greater consistency in terms of the
HTML used to code a page on one site compared to another.
More descriptive semantics
Richer Media Elements
HTML5 is the future.
HTML5 weaknesses
Only modern browsers support it.
The language itself is considered a work in progress
Rich media has to be compressed in multiple formats in order to be
compatible with most browsers.
You have to work with JavaScript
Of course you will find many libraries to aid you will using html5. There are great libraries out there other than JQuery such as Modernizer
The only problem I think that Zend framework might cause will working with HTML5 is that it still doesn't support the new HTML5 inputs.
UPDATE:
AJAX has no difference when it comes to security than the normal http request. Almost all security risks that can be expoited through normal http requests can be done using AJAX, so the ways to mitigate these vulnerabilities are the same.
As a general rule, search engines do not crawl content generated by JavaScript or Ajax. The most notable exception being Google's crawlable Ajax. But that only applies to Google and even then that's a bad idea.
To make your game more search engine friendly you will need to make content available via static links. Without these you essentially have a one page website which is very difficult to rank well. But it can if you obtain enough incoming links which is possible if your game is very good.
I have a requirement where I need to store various bits of browser information such as Brand (eg IE, Chrome..), Model (eg IE, Chrome), Browser Version (eg 7.0.0.0), OS Version (eg Windows 7, OSX, Linux), Flash version info ect. For mobile detection, I'm using WURFL which uses the user agent string and has great support for mobile devices, but not so much for desktop web browsers. I'm using the web patch with WURFL, but to make it useful I would have to add my own override patch to provide some of the items listed above. Is this the best way to do this? Or has anyone found a library out there more suited to this kind of task. If WURFL is the best way to do this, is there an updated and maintained web patch that's more comprehensive than the one provided on the WURFL site?
Based on information received directly from ScientiaMobile the next minor release (estimated at a couple of weeks from the date of this post) of the API will improve the quality of web browser detection and that they are considering including the web patch within the main repository removing the need for a separate patch file.
We are developing a social website and looking to implement video/audio chat for users (people a user is friends with). Most of the talk from the tech team was to use flash. But I don't want users to install anything. Can video/audio/conferencing be done purely in AJAX? Either develop it from scratch or use open source frameworks if any?
Flash is already installed on practically ever browser out there -- except iPhones, iPads, etc. which will likely never support Flash.
AJAX and HTML and CSS currently have no access to video and audio input hardware, so that's a non-starter. In the future this may change.
For now Flash is (for better or for worse) the best way to go.
No, unfortunately you can only do this with a plugin (ie Flash).
I don't believe you have access to video or audio input devices from just the browser.
HTML5 will be the answer in the near future (Work in progress): Link1 and Link2
But for now the only option is Flash
