Drumlin Security Launches Ground-breaking Low Cost PDF Publishi...(p://www.pdf-publishing.com/Ebooks.htm t...),Health

The "publisher" facility in the Drumlin PDF reader/publisher strongly encrypts conventional PDF files with the option to ensure that they can only be read once they have been authorized. Even then, these files can only be opened on the individual PC on which they have been authorized - such files cannot be copied and read elsewhere. Drumlin's publisher facility enables many controls to be applied to such documents, such as enabling or disabling text copy facilities; setting start and end dates for viewing; and specifying the number of times a document may be viewed, and the number of times it may be printed (if at all).

The "authorization" facility within the Drumlin PDF reader enables the recipient of a secured PDF to open the document. They enter an alphanumeric authorization code supplied to them by the publisher of the secured PDF, which is checked against the records on the central Drumlin DRM service. If all is OK the file is decrypted, saved on disk as a new encrypted file and the user can view and optionally print this file according to the settings the publisher has made. For more details and demonstrations please see the web sites.
