DRM protection: what is it, how to remove it?

DRM stands for Digital Right Management, which translates as Digital Rights Management. Thus, the answer to the question: “DRM protection - what is it” will be like this: “This is a class of technologies that publishers use to control content.” This can be expressed as follows: an audio book that was digitally purchased on the site will play normally on the computer with which the purchase was made. But if you copy it to another computer, it will become an unnecessary file that cannot be opened by any player.

drm protection what is it

These examples of DRM technology can be much more complex.

DRM has been designed from the very beginning to prevent the copying of digital products. But the next generation of technology has provided tools to limit viewing, printing, and editing.

In an attempt to protect the interests of copyright holders, DRM protection has caused a considerable number of complaints from users purchasing digital products. The inability to use purchased music through various devices negatively affected customer demand. As a result, publishers realized that it was possible to sell music digitally without imposing DRM protection. It will be even more successful. In other words, DRM protection even negatively affected the sales of various digital products.

DRM protection - what is it?

These technologies over time have been able to gain support in the law. For example, in a large number of countries there are norms in laws that prohibit circumvention of copy protection. In these states, disputes about whether DRM protection is needed, how to remove it, etc., are essentially illegal.

But DRM also has another complication because such technologies can become an obstacle for users to exercise their legal rights. That is why, in order to understand DRM protection - what it is, it is necessary to realize that it is not possible to create backup copies of the purchased work with it.

drm protection how to remove

Without going deeper into legislative practices on the application of various laws in everyday life, it is possible to propose a scheme for removing DRM protection, which will be completely legal in most states. The only exception is Australia. It is possible to create several copies for your needs or for a reserve, but not for sale or distribution. It should be noted that the process of creating copies of more than 10 pieces can be regarded as commercial use. Therefore, you must avoid copying more than the norm. There are no clear restrictions on making copies. For this reason, it is technically possible to lose DRM somewhere in the process of obtaining mp3 copies that are not protected. But using a program that is designed to disable copy protection can be a violation of the law. Thus, when talking about how to bypass DRM protection, you should remember that you can only do this for your personal purposes.

How to do this?

But it’s good that this technology can be removed with the help of programs for general use that are not covered by DRM protection. How to take it off? The best example in this case is mp3Recorder Studio. To do this, you need to enable playback of the purchased audio file with protection when using the program required for this (WMP, iTunes or another). Next, you need to capture audio using mp3Recorder Studio and then save the audio directly to mp3. With this process, the built-in sound card function will be used, which allows you to capture sound already in the middle of the device. Most sound cards have a recording device called a “Stereo Mix”. However, different names are used. This device allows you to capture everything that is reproduced by a sound card. For this, you may need to install the latest driver from the official website of the card manufacturer. Typically, drivers that Windows automatically installs most often disable and hide such a device.

Digital copyright management (or, more simply, copy protection systems) should, in its meaning, protect copyright. But in reality it, not only does not fulfill its main function, but also makes PCs accessible to crackers. How and for what reason is this happening?

Why do you need to remove DRM protection?

DRM systems can be unsafe. With the wrong options for implementing copy protection, it is possible to open holes in the computer security system, which, in turn, would have remained closed if there were no DRM. The point here is that in order to block ordinary copying functions in the OS, rights management software packages need the broadest access rights to system files, and in fact take control of such functions.

A good example of the unsafe implementation of this technology is the Sony BMG copy protection system for audio discs. This rootkit was placed on a large number of audio discs at a music label, which is one of the most famous in the world. When a similar disk was loaded into the computer’s CD-ROM, the installation of the XCP program for WINDOWS automatically began. She was supposed to protect against copying an entire album or the process of theft of tracks from disk.

The XCP rootkit penetrated deep into the OS, and at the same time it was installed completely independently. The ability to uninstall using conventional methods was not possible. Also, during operation, it occupied most of the memory and could be the cause of failures. But the most important thing - absolutely nothing was written about this rootkit and its functioning in the user agreement (EULA). This is despite the fact that almost no one reads such agreements.

But most importantly, the XCP rootkit posed a real threat to the entire system. For example, after installing it, all files that start with $ sys $ acquired the “hidden” mode. It was immediately used by the creators of the viruses. For example, the Breplibot Trojan, which was sent as an attachment to E-mails, was detected only by antiviruses and programs. Such unsafe files were completely invisible to users.

How protection is disconnected

DRM protection on WMV and WMA files is done in stages.

Today, most downloaded audio and video files that are protected (WMP, iTunes, Rhapsody, Napster, Bearshare, Spiral Frog) are DRM files.

The process of writing a file is not complicated. There is a free technique for removing DRM protection from WMV and WMA files. This is done in two steps.

1. You need to write a DRM WMA file to a CD or DRM WMV to a DVD.

2. You need to remove WMV and WMA with protection on the PC itself, after which DRM protection will be disabled.

Rewrite method

This method is the most popular and affordable. It consists in recording DRM WMA and DRM WMV files with a conventional converter that converts recorded and unprotected files. Due to the fact that this technology is easy to use, formats that differ from DRM WMA and DRM WMV will also be supported by converters such as SoundTaxi, NoteBurner and others. But here there are minuses.

New technology

Hook Hook is an advanced technology with which EPUB DRM protection can be disabled. When comparing these programs with rewriting programs, this particular type has a noticeably quick conversion. At the same time, it will not be easy to get to work with some of the DRM formats, which have new high-quality encryption techniques.

After testing, the result was that the protection of DRM WMA and DRM WMV is simply removed using Digital Music Converter. This program can extract audio content from WMV DRM files. Also, this program supports other unprotected formats, such as: mp3, M4b, M4A, WAV, AC3, AAC.

Recommendations

Conversion Steps:

1. First you need to add DRM WMA, DRM WMV or other files that are not protected.

2. You need to select the desired outgoing format.

3. Then click on “Start” and enter the license number.

What is DRM? Why do I need to remove DRM from WMA WMV files?

Speaking about the meaning of the term "DRM protection" (what it is - we have generally discussed above), you need to know: these are programs that protect against copying and complicate actions that are associated with video and audio files. For example, if WMA or WMV files downloaded from WMP are protected using DRM, then it is possible to play them only using compatible devices. If each song was with DRM, then the user would have to purchase this track on disk to listen to it using a player or car radio. For example, if tunes were purchased on iTunes and they are listened to on iPOd, then because they have already been purchased, the user will not need to perform this action again and again. You just need to remove the DRM file, and you will be able to play it on iPod, Zune, PSP, CD-player, PC and other devices.

Warnings

This method is not quite suitable, sometimes it can even cause damage to CD-Roma. WMP has the ability to record only DRM WMA and DRM WMV files. Other formats will require DVD-Ripper.

Due to the long recording process, the conversion speed will not be better. During the recording process, most of the quality of the video or audio may be lost.
