SecuROM is a Digital Rights Management (DRM) system for content distributed via CD-ROM,
DVD-ROM or electronically. It was developed and is maintained by Sony DADC Austria.
SecuROM uses two components for disc-based copy control:
1) Software, in the form of strong encryption, and
2) Hardware, in the form of a special signature applied to the disc during
manufacturing. The protected executable of a CD-ROM/DVD-ROM title is tied to the signature on the
disc by an authentication routine executed at program launch (this can be customized as
described under item 6.3 below). If the original disc is detected, the program
launches properly. If an illegally copied disc is detected in the local disc drive, the program will
not launch and the end-user will receive an error message.
SecuROM Product Activation (DRM for online activation and digital distribution) works in much the
same way. The application is protected with strong encryption and an authentication license is placed
on the end user’s machine via an online activation. If the authentication license is detected on the enduser’s
machine, the program launches properly.
SecuROM technology suppresses CD-ROM to CD-R copying, DVD-ROM to DVD-R
copying, Internet image distribution, and professional piracy.
SecuROM offers many different configurations, including different distribution options (on
disc or digital download) and different authentication methods (original disc check, online
authentication, control of usage rights, etc.).
Any software developer or publisher who has content subject to illegitimate
copying can benefit from the use of SecuROM copy control.
SecuROM is available in two formats: disc-based and online activation-based. The disc
version does not use any Internet connectivity for operation. The online activation-based
system, SecuROM Product Activation, uses an Internet connection to request a license for the
desired application. No personal information is collected, stored, or transmitted during this or
any SecuROM process.
Both the disc-based system and SecuROM Product Activation technologies can be combined.
Different configuration options are available to the publisher.
SecuROM is a DRM system used by software publishers to protect their intellectual property. In the
course of applying the solution, certain files are placed onto the computer for the system to work properly.
No, SecuROM does not install any components or perform any processes at the kernel or ring 0 level.
All SecuROM components and processes occur at ring 3, the normal application level.
No, SecuROM does not damage a computer in any way. Great care has been taken to make sure
the SecuROM system is sound and compatible.
No,SecuROM does not influence PC performance. SecuROM is a library integrated into the protected application,
and recent versions of SecuROM do not contain any stand alone applications.
Some older versions of SecuROM install the “User Access Service”, which allows a user to share
DRM licenses among multiple Operating System user accounts. The User Access Service consumes
very little memory (a few hundred kBytes) and virtually no CPU power. This service does not cause a
No, SecuROM makes no setting changes to any anti-virus program(s), or any software for that matter.
No, SecuROM makes no setting changes to any firewall program(s), or any software for that
If a SecuROM protected application is configured to require an online authentication,
firewalls will notice this process and will inform the user that an internet connection is being
Such standard firewall messages do not mean that SecuROM is opening a network port on
the user’s PC for incoming network connections.
No, SecuROM does not open any ports. SecuROM online activation connects to the license server with regular, outgoing,
encrypted HTTP connections. No backdoor or network port is opened on your PC.
No, SecuROM does not automatically disable any burning or emulation programs. Since some
emulation programs can be used to circumvent SecuROM, it may be necessary for the user to
manually disable such programs before a software title protected with SecuROM can be successfully launched.
No, SecuROM will never disable any application. It does, however, look for applications which can
be used for malicious or hacking purposes. If it identifies such applications on the PC, it will be
necessary for the user to disable them before using the product protected by SecuROM.
No, SecuROM does not damage any optical drives.
No, SecuROM does not disable any printers or scanners and does not change any settings.
No, SecuROM does not change a PC’s ability to recognize a camera or camcorder
A "rootkit" can be described as software or a set of software tools intended to conceal running processes,
files or system data from the operating system and which can open ports to allow remote access to the system.
A "rootkit" makes it possible for viruses or other malicious programs ("malware") to hide content on a user's PC.
In this way, a virus or other malware may remain undetected, even if updated anti-virus software is installed. SecuROM
does not use any rootkit technology.
There is no rootkit in SecuROM. Our understanding is that there is one rootkit detector that
incorrectly flags SecuROM as containing a rootkit. This is an incorrect detection by one software
program. To our knowledge, no other rootkit detectors do so.
No, SecuROM does not collect any personal information.
The Windows registry is a directory which stores settings and options for the operating system for
Microsoft Windows. It contains information and settings for all the hardware, operating system software,
most non-operating system software, users, preferences of the PC, etc. As part of the SecuROM DRM
system, certain license information is stored within this "!CAUTION! NEVER DELETE OR CHANGE
ANY KEY" registry key, contained in HKEY_CURRENT_USER\Software\SecuROM and/or
The reason for naming this key in this way is to prevent users from inadvertently deleting keys/values
stored beneath that key, which would prevent SecuROM from working properly.
Newer SecuROM versions store the license information in a registry key named “License information”, similarly contained
in HKEY_CURRENT_USER\Software\SecuROM and/or HKEY_LOCAL_MACHINE\Software\SecuROM.

SecuROM itself is a library, integrated into the actual application, and not a standalone application. In
this sense, SecuROM is similar to other software libraries, like 3D engines or spell checkers, which
are integrated into other applications. SecuROM does, however, use data storage and libraries which
are required to fullfil its purpose, much like other libraries also use their own data (e.g., spellcheck
dictionaries) and libraries (e.g., 3D graphics calculation or game physics libraries).
Since SecuROM is not a standalone application, no executable SecuROM “application” remains on
the system after deinstallation. However, DRM license information remains stored on the PC, as
described in section 4.4.
By default, SecuROM does not install any permanently active applications, services, or drivers.
Some older versions of SecuROM protected applications use a special configuration which will install
a Windows Service called “User Access Service”. This service allows a user to share DRM licenses
among multiple users of the same PC.
This service is only used during the initial SecuROM authentication upon the start of the application.
At all other times, the service runs in the “idle” mode. This means that it is passively waiting for a
SecuROM protected application to perform the respective DRM authentication during the startup of
that protected application.
SecuROM supports an activation “revoke” process which makes your previous license available to another user. However,
each publisher must decide whether or not to include the “revoke” feature in its application.
We should distinguish between
(a) the online request for a license and the retrieval of such a license during the online activation process, and
(b) the verification of the license at each application start.
Typically, step (a) is performed only once, while step (b) happens at every start. However, publishers can configure SecuROM
to request an online license periodically. This would mean that after the online activation, you can use the application for the
time period selected by the publisher. If you start the application after that period, you would be requested to re-obtain the
license. SecuROM itself is configurable and supports both cases (initial activation only or periodic re-activation).
SecuROM has built in tolerances to allow for changes in the system configuration. Typically, you should be able to use
your activated applications after some system changes. The default setting in SecuROM allows you to use your activated applications
upon system changes like a replaced graphics card, upgraded Windows version, or a faster CPU.
However, SecuROM can be configured by the publisher to be more lenient or more strict with regards to changes to the system
configuration. This means that publishers can configure the tolerance threshold at their own discretion, so there might be
applications which do not tolerate a single change and there might be other applications which tolerate many major changes.
DRM license information stores the usage rights of DRM protected applications. License information is not executable code.
SecuROM does not install or invoke any other code, EXE, DLL, service, or driver along with this license information. License
information does not contain any information related to the execution of additional code. It only contains relevant usage rights
configuration information (e.g., how many days are left for a free trial period of an application) so
that SecuROM can accomplish its DRM functionality.
The stored information depends on the respective protection settings used for a specific application. SecuROM supports many different configurations.
Some typical examples follow.
Note: All values (number of launches, minutes of playtime, etc.) given below are mere example
values. These values can be configured in the SecuROM protection tool by the publisher.
Information stored in the DRM license information
Online activation required
Unlock code received after online activation. If SecuROM finds that information, it knows that
the application has already been successfully activated.
Further information stored here is the serial code as input by the user.
Allow only a certain number of launches
Launch counter. SecuROM will refuse to launch the application if the launch counter has
exceeded the maximum number of launches as configured in the application (EXE) during
protection by the publisher.
Time Limit (for example, the publisher can set the application to run for only 60 minutes)
SecuROM stores the minutes of playtime that have passed. Once the time limit, has been reached, the application will stop running.
Day Limit (for example, the publisher can set the application to to run for only 10 days after the first launch)
SecuROM stores the date and time of the first launch. In each subsequent launch (e.g., some
days later), SecuROM will verify whether this launch is still within the allowed timeframe.
Other protection options supported by SecuROM are to check for an original disc only the first
time, every nth launch, every nth day, etc. Other similar protection options are also available.
Launch count information, activation information, consumed playtime information, allowed
timeframe, etc. are all stored within these registry keys. Note that this information is stored in an
encrypted manner for obvious reasons, as otherwise it would be easily possible to cheat the DRM system.
Why is this information protected against deletion?
Allowing for the easy deletion of this information would essentially remove the copy protection
from the application, allowing easy copying of the publisher’s intellectual property. Deleting this
information also impacts SecuROM’s DRM functionality. Some examples to illustrate this:
Consequence if DRM license information is deleted
Online activation required
Imagine that someone first correctly activates (unlocks) an application and then deletes the
DRM license information.
SecuROM would then believe that the application has not yet been unlocked and would
ask for a new activation. This would result in the user “losing” an activation.
Allow up to only 10 launches of an application
Imagine that someone launches such an application 10 times, and then deletes the DRM license information.
SecuROM would then believe that the application has not yet been launched and would
again permit 10 additional launches.
Obviously, this is not in the interest of the rights owner.
SecuROM supports 32-bit executables for Windows written in C, C++,
Pascal, and Macromedia Director as well as software in Macintosh format.

Historically, SecuROM offers the highest CD/DVD drive compatibility of
any DRM system on the market. Incompatibility occurrences are usually resolved in a short
period of time.
Yes. All of the content of a SecuROM-protected title can be installed to a hard disk. In fact, most protected titles
use a full hard drive installation. However, in order for the title to launch properly, the genuine SecuROM CD-ROM/DVD-ROM must
be present in a local drive. Once authentication takes place, the title can run solely from the hard disk.
Financial models show that an investment in SecuROM reaches a break-even
point at piracy rates as low as 1%. Higher piracy rates yield a greater return. Please
contact our sales group through our Online Inquiry section for more details.

Yes. SecuROMs Advanced Programming Interface (SecuROM API)
allows custom copy control. This requires that some additional code be placed in the
program code to work hand-in-hand with the SecuROM encryption engine. The
use of this feature allows for "programmer-placed" authentication checks for original CD,
valid licenses, and executable modifications (e.g. checksums). Contact
support@SecuROM.com for more details.
Yes. A typical application of a multi-disc set consists of multiple install discs and
one disc which is designated as the "play" disc. The SecuROM authentication
signature can be applied to any and all discs. The signature does not have to be on the
same disc as the protected executable. Please contact support@SecuROM.com for additional
Yes. Depending on the configuration options chosen by the publisher, each participant will require an
original SecuROM protected disc in their local drive, and/or a valid SecuROM Product Activation license.
Yes. There is no limit to the number of applications that can be protected on a single
SecuROM- protected disc. If this is a desired option, please contact
support@SecuROM.com for details on how to best encrypt multiple titles.
Yes. If you wish to release a patch of a protected title, updated executables can be
encrypted using the same project on the SecuROM server that was used with
the original release. The patch can be tested and then released. The authentication
routine for the patch will be the same as for the original. An added benefit to
re-encryption of an executable for patch release is the ability to take advantage of any
updates to the security or compatibility of SecuROM made since the original
Yes. Care should be taken to avoid release of any unprotected versions of a title. It
is fairly simple for hackers to swap out an unprotected executable for a protected one
and burn unprotected copies, defeating the intent of copy control.
Yes. If the beta version contains an executable that can be easily modified to run the
protected title, once again, pirated duplicates may appear. The unprotected executable
may even find its way onto the Internet and impact sales. One strategy for beta or press
release versions is to distribute a protected title on CD-R and link the executable to a
title-specific SecuROM disc. Contact support@SecuROM.com for more
SecuROM offers the highest level of security against one-to-one copies and other
The SecuROM DRM system is under continuous improvement. Security and
compatibility issue improvements require upgrades to the SecuROM encryption
engine. Upgrades, as they become available, are loaded on the server side. No upgrade to
the local encryption software is necessary. All SecuROM customers are
notified of updates with corresponding release notes.
An executable is protected using a 128 bit, SSL Internet connection and is received during the same
session. The SecuROM server is available 24/7. Consequently, unlike other protection technologies, SecuROM offers virtually instant encryption.
There is no charge for doing multiple encryptions of software. Consequently, an
executable can be protected and tested throughout the development phase. Pre-production
testing is accomplished by using a publisher-unique Universal Key Disc (UKD). UKDs are
supplied to the publisher at no charge and are included with the software CD shipment.
Charges apply only upon replication of the actual title.
No. The master CD or DVD is sent to an approved SecuROM enabled
replicator without any additional steps (other than inclusion of the protected
executable). The publisher should notify the replicator as to the location and name of
the protected executable(s). Also, if the executable is embedded in an installer, a
method for extracting it should be supplied. Please contact our sales group through our
Online Inquiry section for a complete listing of SecuROM enabled
