Today, we received an inquiry from a user, and the content of his letter is as follows:
Hello. I used the free version of the program. But I can’t test it. I couldn’t add my Powerpoint (PPTX) files to the program. I want to test them? Does the pptx work smoothly after protection (encryption)? Animations work smoothly? How can I test the full version of the program? I want to buy the program after testing. Can you help me?
I want to do the following:
- Upload my Powerpoint files to a USB
- The owner of the USB should only use this file on the flash drive.
- He can’t copy, print or save it.
- He can’t share the contents of the flash drive with anyone else.
- The animations, videos, and music in Powerpoint should work smoothly.
From the user’s letter, we can clearly sort out his core needs and possible usage scenarios, which are also common problems encountered by many users who have the need to protect PPT files, such as how to realize PowerPoint USB encryption, PPT anti-copy and anti-print, and protect the smooth playback of PPT animations.
First, looking at the core needs, the user wants to store PowerPoint files on a USB, and the file can only be used on that USB. It is not allowed to be copied, printed, saved, or shared with others. At the same time, it is necessary to ensure that the animations, videos, and music in the file can run smoothly. In addition, because the free version cannot add PPTX files for testing, the user wants to know how to test the full version and plans to buy it after testing, which also reflects his emphasis on the practicality and adaptability of the software.
Then, analyzing the possible usage scenarios, such needs are likely to appear in business cooperation, academic exchanges, or internal data sharing. For example, a company’s salesperson needs to carry a PPT containing the core product plan to visit customers. In order to prevent the plan from being obtained by competitors, it is necessary to restrict the file to be used only on a specific USB and not to be copied and spread. When researchers share PPTs of their research results at academic conferences, they will also have similar restrictive needs to protect the confidentiality and originality of their research. In these scenarios, the security of the file is the primary consideration, and at the same time, it must not affect the normal display effect of the PPT, otherwise, it will affect the quality of communication.
In the field of PowerPoint file protection, there are many competitors in the market, and different products have their own characteristics in PPT encryption, anti-screen recording, and animation retention.
StarForce PPT Copy Protection can convert PPT or PPTX files into applications for protection, prevent files from being copied, edited and modified, block screen capture, and control file distribution. The protected presentation runs in demo mode and supports binding files to CD, DVD, USB storage devices, etc. However, there may be room for optimization in the perfect presentation of animation effects, which may not be ideal for users who need high-fidelity display of PPT animations.
Dingling Class, as a PPT encryption distribution authorization and sharing platform, performs well in anti-screen recording. As long as you enable courseware encryption with one click, the corresponding content can only be played in its client. No matter in local or remote sharing, or screen projection, it is impossible to take screenshots and record screens, which fully protects intellectual property rights. Moreover, it can perfectly reproduce the animation effects and audio-visual effects of complex PPTs. However, in terms of the flexibility of restricting the use of devices for files, compared with some software specially designed for device binding, it may be slightly insufficient, and it is difficult to meet the needs of strictly binding PPT to a specific USB.
There are also some specific USB anti-copy and anti-copy software, which have the functions of file anti-copy, anti-screenshot, and anti-screen recording, and can prevent virus damage. Put courseware PPT and other files on a protected USB flash drive or mobile hard disk, and others can open and view them but cannot copy them. However, such software often focuses more on the protection at the storage device level. For the DRM (Digital Rights Management) function of the PPT file itself, in terms of retaining details such as animations, it may not be precise enough, and animation freezes or distortions are prone to occur.
Adobe Acrobat Pro DC also has certain file protection capabilities. It can merge PPT and other different format files into PDF, and set “document protection” to prevent others from copying, printing, and editing the information. But it mainly focuses on PDF files, and is not specialized in device restrictions and animation DRM for original PPT files, so it cannot well meet the user’s needs for using PPT on USB and retaining animations.
Boxcryptor, as an outstanding document encryption tool, adopts high-intensity encryption algorithms such as AES-256 and RSA. Its encryption ability is excellent, but it lacks targeted optimization in PPT file playback scenarios, such as anti-screen recording and ensuring animation fluency, so it has limited practicality for users focusing on PPT protection.
Cryptomator is a cross-platform open-source software that uses client encryption technology and AES-256 encryption algorithm to encrypt and obfuscate file names and folder structures, and provides a virtual drive interface to make encryption operations transparent. However, it has no outstanding performance in the specific protection of PPT files, such as restricting the use of devices, preventing screen recording, and ensuring DRM for PPT animations, so it is difficult to meet the personalized needs of users.
AxCrypt is easy to operate. You can encrypt files with a right click, and it can also automatically encrypt and upload to the network disk to achieve cross-device synchronization. However, it has no special functional design in protecting PPT files for use on specific devices, preventing unauthorized screen recording, and maintaining the integrity of PPT animations, so it cannot cope with complex PPT protection scenarios.
NordLocker provides end-to-end encryption. After files are encrypted, they are transmitted to the cloud, and only users know the key. However, its advantages are more reflected in cloud file transmission encryption. It does not provide effective solutions for restricting the use of PPT files on local devices, preventing screen recording, and ensuring the normal operation of animations, so it is not suitable for scenarios where PPT needs to be used on USB.
If you want to find a more comprehensive solution to meet the above needs, Gilisoft will be an excellent choice. Gilisoft DRM Protection can securely encrypt PowerPoint files. It uses the Advanced Encryption Standard (AES), the same encryption algorithm used by the National Security Agency (NSA) for “top-secret” documents, which can provide government-level security and is a reliable PPT encryption tool.
With Gilisoft Copy Protection, you can lock PPT files to authorized devices, which can ensure that files will not be shared by others, and at the same time prevent illegal copying and distribution, perfectly realizing the function of PPT anti-copy and anti-print. You can create non-sharable GCP files. When the end user opens the protected PPT for the first time, he will be prompted that the file has been registered to his device and cannot be opened on other devices, meeting the need to bind PPT to USB. In terms of anti-screen recording, Gilisoft effectively prevents unauthorized screen recording through a strict encryption mechanism. Moreover, Gilisoft ‘s encryption method is specially designed to ensure that the original functions of the file such as animations, videos, and music are not affected. The encrypted files will not have any freezes or quality loss during playback or demonstration, and perform excellently in the DRM function of retaining PPT animations, allowing PPT animations to play smoothly.
If you want to test the full version of our program, you can visit our official website and follow the prompts to try it out. We believe that after testing, you will find that Gilisoft ‘s solution fully meets your needs. Whether it is PowerPoint USB encryption, anti-copy, or retaining animation effects, it can be done excellently, and then you can make a wise purchase decision.
