VarySafe 1.2.0001 is a File Encryption product from cheewoo.com, get 5 Stars SoftSea Rating, VarySafe is a document security program especially for the people who need to release / send their digital document data (i.e. CAD drawing files, world processing files, spread sheet files, PDF files, photo and image files etc.) to others and want that their digital data should not be redistributed to the other third-parties. Let's guess that if you have a CAD drawing file and need to send that drawing to other company for manufacturing. In this case, it is very easy to send/release your drawing to them, but it is hard to restrict their redistribution of your data to others. VarySafe gives you the simply robust method to restrict their redistribution.
For VarySafe to achieve this goal, VarySafe use hardware fingerprint and ActiveCapsule technologies. At first, let's think about hardware fingerprint technology. Each personal computer system includes several physical hardware components (i.e. CPU, mother board, hard drive, network card etc. ) and each components have there own properties (i.e. CPU Name ="AAA", CPU clock ="BBB", etc.) . VarySafe detects each typical physical hardware components properties and define them as numeric values. Finally VarySafe combines those numeric values into one alpha numerical string which so called hardware fingerprint. This hardware fingerprint represents each computer systems physical hardware combinations and their properties. Even same brand same model computer products have different hardware fingerprints, because some hardware components have their own serial number individually (ex. each hard driver has their own unique SMART serial number.). By using hardware fingerprint, VarySafe could identify each computer system successfully.
VarySafe also combines your data (ex. CAD drawing information, Word text information etc.) with VarySafe's unique viewer application, and then makes data contained a single executable file. Logically speaking, your data are wrapped with a executable application. We call this data contained single executable file as "ActiveCapsule" file. In this terminology, the ActiveCapsule means intelligent executable viewer/security application software which wraps and protects your data. Because the data are passive components in the computing world, it is hard to protect themselves by themselves. Every body can try to attack your data by using their software programs. Even though, you can encrypt / pack / scramble your data, you have to reveal the password or method to decrypt / unpack / unscramble your data for your data user, because he /she has to open your original raw data from their application software (i.e. CAD application, word processor application, spreadsheet application software etc.). Just in front of your data user's software program, you have to reveal your original raw data. This situation is based on that because you send only data to your data user.
VarySafe supports you to escape from this situation. VarySafe builds data wrapped a single executable viewer/authentication/protection software file (ActiveCapsule file) for you. Finally, you can send this ActiveCapsule file to he/she who may use your data. ActiveCapsule file can run under your data user's personal computer system stand alone. No other software (i.e. CAD application, word processor, spread sheet, PDF reader etc.) is needed for your data. In the initialize stage of ActiveCapsule file running, ActiveCapsule checks whether current computer system where ActiveCapsule is running is identical with your data user's computer or not based on inside data record. In this stage, ActiveCapsule use hardware fingerprint to identify current computer system. If hardware fingerprint is identical with internal record, ActiveCapsule unwraps your data and shows it to your data user. Incase of hardware fingerprint mismatch, ActiveCapsule terminated without any unwrap process. By using this mechanism, you can only show your data to only authenticated users, and restrict redistribution.
For you to input your document data into ActiveCapsule file, VarySafe supply special printer driver called VarySafe printer. During the installation process, VarySafe setup automatically install VarySafe printer in your computer. This printer works similar with other virtual printers (i.e. Adobe Acrobat distiller printer, MS Document Image Writer etc.). As soon as you prints any document into this printer, VarySafe printer gathers all printing information and converts it with a single VarySafe ActiveCapsule file. By using this printer, you can easily convert any printable documents with ActiveCapsule file.
Features:
- Generate data/viewer encapsulated stand alone executable file which only running in the author specified computer.
- Set specific expiration date (After author specified date, executable file will not decrypt/open/view internal data and authentication will be expired.).
- Set view or view + print permission.
- Set stamp numbers on the viewers screen and print page (Stamp gives a traceability, in case of screen capturing and/or print paper copying.).
- Use any printing data as a input by using VarySafe printer.
- Use 2-byte languages data (e.g. Asian languages are supported.).
- Send single data/viewer contained stand alone executable file without any software dependency (No viewer, no software is needed to use.).
- Increase security by using industry proven crypto algorithms for data/viewer encryption and decryption (See the algorithms in following section.).
- Increase security by running the executable file without any temporally files of the decrypted data (This makes secure environment for data recovery by using temporally file recovering.).
- Increase security by excluding the decryption key string from the executable file (In the stand alone executable file, there is no data decryption key string inside. This technique able to increase security.).
- Increase security by varying hardware fingerprint scheme (Each register user have there own hardware fingerprint scheme.
