Individual permission settings decide what the recipient of a file can do with it and policies such as "view-only", "comments-only" or "enforce change tracking" can be applied.
This creates restricted areas within an ownCloud installation where sensitive documents are protected, with the only prerequisites being Internet access and a Web browser.
Collabora is the biggest developer of the free office suite, LibreOffice, and has put the application in the cloud as well.
"Since ownCloud is an on-premises private cloud solution, access to such secure data rooms can also be granted to external authorised readers without the original confidential data leaving the company’s servers – because the text displayed on readers’ computers is composed of images. This enables convenient collaboration, for example with consulting lawyers or R&D partners, while ensuring that security and compliance rules are met."
Collabora general manager Michael Meeks, a veteran open source software developer, said: "With the development of Secure View, we can now offer our Collabora Online users even more ways to collaborate and work with documents that require a particular level of security.
“Collabora Online and ownCloud complement each other perfectly by combining convenience and flexibility, when editing and viewing documents, with maximum data exchange security.”
Microsoft offers similar functionality as Secure View within its Azure cloud but the user is locked into using proprietary software from a single company.
“The joint development of Secure View, an unprecedented feature, is a great example of what can be achieved with flexible integration solutions,” ownCloud chief executive Tobias Gerlinger said.
“In this way, we can offer our users enterprise-relevant new features without getting bogged down with too many different development ventures – as is the case with some competing products. For ownCloud,
stability, security and performance of the core product are the top priorities.”
