Abstract: Various embodiments described herein relate to methods, systems, apparatus and computer-readable media for providing a graphical representation of a plurality of statements in a tree-like structure. At least a portion of the statements is displayed on a screen. Each displayed statement comprises a contents portion and an assigned classification. The statements further have one or more associated quality designations. According to one embodiment, the assigned classification is selected from a set of at least two classifications. Each classification specifies a relationship of an associated statement to another statement in said tree-like structure.

Abstract: A method, a system, and computer-readable media having instruction for controlling client devices and server are provided for managing digital data According to one aspect, a method comprises associating digital data with predefined sets of digital data, computing a leaf hash values over some or all of the digital data and/or over identifications of some or all of the digital data that are associated with the predefined sets, and computing a root hash value, whereby the underlying hash algorithm has as an input at least said leaf hash values. The method further comprises determining the consistency of given digital data with said root hash value by identifying the set of digital data that is associated with given digital data, re-obtaining said root hash value, re-obtaining the hash values over which said root hash value was computed, computing a hash value over said re-obtained hash values, and comparing said re-obtained root hash values with said in the previous step computed hash value.

Abstract: A gateway for connecting a public network to an internal network is provided. The gateway comprises a control unit for controlling transmission of incoming and/or outgoing data between a remote device in the public network and an internal device in the internal network; a public port connected to the public network; an internal port connected to the internal network; and a storage unit storing a list of public key identifiers and respectively associated internal network addresses of internal devices; wherein the control unit is adapted for identifying a destination of the incoming data, which are addressed to a public network address of the gateway, by determining an internal network address of the internal device based on public key information included in the incoming data and the list of public key identifiers and associated internal network addresses.

Abstract: A server in a public key system stores a list of fingerprints of digital data. Another fingerprint is computed for this list of fingerprints and provided to a client terminal. A client terminal in a public key system obtains a list of fingerprints of digital data from a first source in this system. The client terminal further obtains a fingerprint for that list of fingerprints from a first source as well as from a second source for comparing both obtained fingerprints.

Abstract: In a server of a public key system a list of fingerprints of public keys is stored and provided. Furthermore, a fingerprint of the fingerprint list is calculated for providing the calculated fingerprint of the list of fingerprints. A client terminal of the public key system receives a list of fingerprints of public keys and a first fingerprint thereof from a first source. The client terminal further receives a second fingerprint of the list of fingerprints from a second source and compares the first and the second received fingerprint.

Abstract: A system and method of processing an electronic document in a system handling electronic documents in accordance with their classification into classes for electronic documents. The electronic document is supplemented with a classification tool, the classification tool allowing a recipient of the document to manually classify the electronic document as a document of a particular class. Then the supplemented electronic document is transmitted to the recipient. A classification information for the electronic document is provided to the system in response to an interaction of the recipient with the classification tool. The classification information representing the particular class associated to the interaction of the recipient.
