Abstract
A method and apparatus for secure transmission of digital document data between multiple devices are provided. At a sending station, a document file is generated and a user-defined character string is inputted by an operator in the local user interface. Then, the sending station automatically forms an encryption key based on the user-defined character string and encrypts the document file therewith. However, one or more predetermined specifying header items of the file are not encrypted, to facilitate recognition and handling of the file. A transmission file, including the encrypted document file, is then transmitted towards a receiving station, where the encrypted document file is decrypted based on the same user-defined character string entered at the sending station, when the latter is entered in the local user interface of the receiving station. Even though the transmission file is encrypted, the unencrypted header items enable file handling, such as routing, and accounting.
