In the “Secure PDF Files With a Password in C#, VB, and Java” article, we described how to use the PDFFile class from the PDF SDK to password protect and encrypt PDF files. Using the PDFFile class also makes digitally signing PDF files just as easy! The PDFFile class is available for .NET FX, .NET Core, and Java.

In the “Merge PDF Files - C#, VB, and Java Code” article, we described how to use the PDFFile class from the PDF SDK to merge multiple PDF files into one with just a couple lines of code. Using the PDFFile class also makes PDF encryption, decryption, and password protection just as easy! The PDFFile class is available for .NET FX, .NET Core, and Java.

LEADTOOLS received several updates to its document and medical imaging toolkits today. Most notably, the LEADTOOLS HTML5/JavaScript Document Viewer now has the ability to run within even the most restricted environments without compromising security. Several under-the-hood updates including logging, diskless caching, configuration settings, and the like all contribute to create a lightweight, web-based viewer that can be hosted on both Windows and Linux servers, as well as third-party cloud hosting services such as Microsoft Azure.

Streaming audio/video multimedia content takes a prominent place in today's culture. It is everywhere from home entertainment services, Unmanned Aerial Vehicles (UAVs), security and surveillance systems, and even baby monitors. What you might not know is that one format powers a large majority of those systems and products. MPEG-2 Transport Stream is at the heart of many streaming technologies you use and benefit from on a daily basis.

Naturally, LEADTOOLS has some powerful SDK features that can help you implement and take advantage of the many benefits of MPEG-2 Transport Stream. Check out this month's white paper for a detailed look into the world of MPEG-2 Transport Stream and how to use it in your application to send and receive live audio/video streams with KLV metadata, DVR and more.

One of our favorite things to do at LEAD is be a part of making the world a better place to live through our technologies. As an SDK company, we enjoy a much broader reach than our local community since we get to be a part of many projects and ideas that our customers are coming up with. For example, LEADTOOLS DICOM and PACS technologies aren't serving just a couple local hospitals, but thousands of hospitals around the globe. That's literally hundreds of thousands, if not millions, of X-rays, CTs, MRIs, and the like displayed by LEADTOOLS.

If you have been following the news at all the past several months, it's been rather violent. In response, local governing bodies are starting to do more to increase security measures through printing and scanning ID cards for children and families that attend public events, or implementing stricter ID protocols at bars. Our sales and support teams have been getting a lot of questions about how LEADTOOLS can help these municipalities and socially aware developers with improving security.
