What is the safest method for sharing PDF documents?

In the modern world lots of documents are created and disseminated over the internet or through private networks. There is constant need for document sharing but this is plagued by the risk of documents landing in the wrong hands or getting stolen. People also do not want unauthorized changes to be made to sensitive documents. All these problems can be solved if we use secure adobe PDF as our document sharing format.

The idea behind using secure adobe PDF is that users cannot be entirely stopped from copying a document. If however the PDF is encrypted then whoever gets a copy cannot utilize it and this is because you (the author) have encrypted the document and only you have the key to open it. However securing this key, is the ‘key’ to the security. The PDF protection software available from www.locklizard.com enables you to lock your PDFs to specific computers thus allowing you to limit document sharing to only those who need to. Decryption keys are never divulged to users, ensuring that people cannot pass them between themselves so documents cannot be shared.
