Abstract
There is provided a method of, computer programs for and apparatus for providing and accessing digital content such as a news item. A news provider generates a news item, creates a digitally signed version of the news item and packages them together with a digital certificate issued by a certificate authority containing the public key required to decrypt the digitally signed version. The package is posted to a server and is transmitted, or made available or transmission, over a public data network together with a computer program for verifying the news item. A receiving party receives, over the public data network, the package at a client device and is provided with means for launching, and if necessary first downloading, the verifying program. The verifying program uses the public key contained in the certificate to verify the digitally signed news item. Before being first used to verify a news item, the verifying program receives a shared secret from the receiving party which is stored locally to the client device and is used by the verifying program to confirm that it performed the verification process.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
