Abstract
The present invention relates to a method for storing a file originating from a source location at a target location, comprising of receiving the file at the target location, storing the file at the target location, and encrypting the file irreversibly in at least a stored state at the target location using a key originating from the source location, this prior to storage at the target location. The invention also relates to a receiving device for storing a file originating from a source location at a target location and a system for storing a file originating from a source location at least one target location.
Claims16
Method for storing a file originating from a source location at a target location, comprising of:
- receiving the file at the target location,
- storing the file at the target location,
- characterized by
- encrypting the file prior to receipt using a key originating from the source location, and
- encrypting the file irreversibly in at least stored state at the target location using a key originating from the source location, this prior to storage at the target location.
Method as claimed in any of the foregoing claims,
- characterized by
- irreversibly encrypting the file after receipt.
Method as claimed in any of the foregoing claims,
- characterized in that
- the target location is a network location such as an internet location or a LAN (Local Area Network) location.
Method as claimed in any of the foregoing claims,
- characterized in that
- encryption of the file prior to receipt comprises of:
- asymmetrically encrypting the file using a public key originating from the source location.
Method as claimed in any of the foregoing claims,
- characterized in that
- the key originating from the source location during the encryption of the file prior to receipt and the key originating from the source location during the irreversible encryption of the file at the target location are the same.
Method as claimed in any of the foregoing claims,
- characterized by
- compressing the file prior to receipt.
Method as claimed in any of the foregoing claims,
- characterized by
- dividing the file into at least two part-files prior to receipt.
Receiving device for storing a file originating from a source location at a target location, comprising:
- a receiving unit which receives the file at the target location,
- an encryption unit which encrypts the file at the target location,
- a storage unit which stores the file at the target location,
- characterized in that
- the encryption unit encrypts the file irreversibly in at least a stored state at the target location using a key originating from the source location.
System for storing a file originating from a source location at least one target location, comprising:
- a transmitting device at the source location which transmits the file from the source location to the at least one target location, and
- a receiving device at the target location, comprising:
- a receiving unit which receives the file at the target location,
- an encryption unit which encrypts the file at the target location,
- a storage unit which stores the file at the target location,
- characterized in that
- the encryption unit encrypts the file irreversibly in at least a stored state at the target location using a key originating from the source location.
