More people are using personal applications to save their financial data on their home computers. Software is advancing dramatically, and over the last several years, users have been discovering the power of apps for management of personal documents.

On mobile devices, users can keep spreadsheets, budgets, and even contracts for home. With this convenience and power of applications comes a critical factor: security. Whenever making apps easier, developers need to consider security, and users must always keep in mind that their data must be preserved somehow.

With PDF Reader, users have a variety of choices for the securing of their personal data and documents. Choose to password protect your documents, and rest assured that even if they are copied accidentally and shared, they will remain safe. Adding a password to a PDF secures the PDF so that it can not be opened. PDF reading software such as Adobe Reader recognizes that there is a password, and will not allow users to view if the correct password is not entered. This added level of security is essential for the preserving of your financial documents, tax reports, or even contracts. Kdan knows that if more people are given easy tools for security, they will use them and make breaches and leaks of financial data less common.

Protect your Schoolwork

With the advent of online e-learning, more people are students than ever before in history. Students are constantly producing high-quality, original work, alongside large numbers of their peers. How can students work together and collaborate, while still producing original, creative works which aren't similar to the works of others? This is a fundamental concept in security that must be considered. Students have a strong, practical need to keep their work original and un-viewed by others until the time comes for peer review.

With password protect for PDF documents, students can understand intuitively that their work hasn't been edited or seen by anyone else until it's time to turn the work in. Students can share the password-protected work in group file upload locations, on flash drives, or on shared network storage locations. Students can send their documents in emails and messages to their peers, professors, and more. All the while, they can have an added layer of assurance.

Only those people who are intended to view can view, and only those that should edit can edit. What if your precious work is shared with the class? Instead of needing to re-do it, generating again original work, make it password protected. When it's shared, it's still blocked and protected from prying eyes, and only viewable by the people you want.
