Abstract: This application relates to the ability to receive data, typically transmitted from a remote location by a broadcaster in a digital encoded format. Typically the data can be provided in an encrypted format for security purposes. In order to allow the data which is to be held in a memory to be processed, but still be secure, the method and system allows for the addition of location identifiers for the material in the memory. Thus, in one embodiment, the received encrypted material is first descrambled or decrypted and parsed to allow the generation of location identifiers for portions of the material. Once parsed, the location identifiers are stored in a database in the receiver and the material is again encrypted locally at the receiver prior to storage in the memory. Typically these steps are performed as one process, thereby preventing unauthorised access to the material when it is in a descrambled or decrypted form.
