Abstract

A method for accessing content of encrypted data item(s) by a terminal device operating in a digital environment, according to which before the data item is being accessed by the terminal device, it is modified after being intercepted if found to be encrypted. The wrapper of the data item is modified or replaced by embedding a URL with a unique identifier and a message into the wrapper of the data item. If a supported terminal device attempts to accesses the modified data item, the client application natively consumes the data from the modified data item and ignores its wrapper. If not, the message and the URL are displayed on the terminal device and the user browses the URL. Then after authentication, a web server locates the modified data item using the unique identifier, retrieves and decrypts the modified item and converts the decrypted modified data item to a format that can be consumed by the browser. Then, if the user has permission, he can view the data item by rendering it to the browser in his terminal device.
