Scanned image data or cached scanned data is encrypted. It can only be accessed by the Dynamsoft scanning service. For any other program, even if it takes the image, it is not able to access any data inside it.
Every time the Web TWAIN control is initialized, there is a random ID (working like a session ID) assigned. When an application tries to view the images, it will need to provide the ID. For example
Limit the access of scanner device to the registered web scanning application only. It is done by matching the current website domain to the registered domain in the product key.
- Greatly reduced development time. The TWAIN 1.9 specification alone is 552 pages long.
- It could take months for you to get familiar with specification and build a TWAIN plugin from scratch.
With Dynamic Web TWAIN, most applications can implement TWAIN support with no more than a few lines of code.
- Browsers change quickly. The application is much easier to maintain by using Dynamic Web TWAIN SDK.
Even greater time savings. By tapping into Dynamsoft's TWAIN knowledge base via our Virtual Developer Service, the total time needed to build your scanning solution could be reduced from months to days.
- Reduced product time to market. The speed of product delivery is very important.
