Description

Data processing device

and method of operation thereof

The invention relates to a data processing arrangement for exchanging information, with a network device which connects a plurality of data processing devices as participants, with at least one first information-providing subscriber who receives at least one information request from at least one second information-requesting subscriber. Moreover, the invention relates to a method for operating such a data processing arrangement.

Many processes and processes of daily life are already based on the fact that data processing devices connected in a network exchange information, be it that mainframes exchange or align with one another, or even that a single user uses a single computer or even his smartphone or tablet an information query in the form of a search query addressed to a corresponding search engine. Regularly it comes to accesses to a target computer, which seeks to answer this information query by accessing a stored in his or her databases information stock.

Regrettably, in the networks in question, not only users with noble intentions are on the way, so that a threat of both individual participants of the networks, as well as entire infrastructure by so-called malicious programs is omnipresent. Some examples of this are programs, by means of which so-called (D) DOS attacks (Distributed) Denial of Service ausge ^¬ leads and thereby individual data processing devices, as well as whole arrangements can be paralyzed. Furthermore, one could also think of extortion in the form of ransomware, for example, inter alia, to so-called crypto-Trojans, which encrypts their own data and issues the required key for ^decryption only against payment of a sum of money. Finally, there is a large amount of spyware that is capable for For databases ^¬ spy to obtain eg competitive advantage from the knowledge advantage. The scenarios described here have in common that a computer as a data processing device per se initially can not distinguish whether an instruction is in the owner's sense or not. Therefore, security gaps can not be excluded for the future in the area of system programs or application programs. In today's connection technology, therefore, an attack on computers or databases will always be possible. As soon as there is a direct physical connection, e.g. B. over the Internet, between two participating in the respective network data processing devices running in the background from a variety of programs that allow it due to, for example, security vulnerabilities described above, to inject malicious code into a target computer as a participant, and gain access to usable data.

It is therefore the object to provide an apparatus and a method to make available, which allows each independently of the network architecture, a reliable, safe response to a information request of a informationsanfordernden subscriber without a participating informationsanfordernde Since ^¬ tenverarbeitungsvorrichtung access to or control obtained through data, which processes an information-giving participant. This object is solved by the features of the independent claims. Thus, the solution consists in particular to the fact, in a device of the initially ge ^¬ type called to be provided at least one first party with at least one treatment device which converts at least one information retrieval in an encoded format, as well as the first party with at least egg ^¬ ner conversion means provided which coded, mapped information ^¬ onsabfragen contactlessly recorded and converted into a machine-readable format, and to provide the at least one first participant with a processing device, which generates at least one response information based on the information query under comparison with a held information stock and by returning the at least one answer information in the direction of the second subscriber answers the at least one information query.

The invention thus consists, in particular, of converting an inquiry made electronically to the first subscriber into a format which allows an illustration (in principle of any kind), for example a graphic representation which does not provide for further direct electronic processing. This Ab ^¬ education of coded format is detected contactless by a conversion device, converted back and then passed to a processing entity of the first participant, between the images and the converter so no direct communication takes place, the image of the encoded format is thus in Essentially a disclosure of the information in just the selected coded format, the mapping can also be regarded as "send" without specific addressee and in particular without a send / receive protocol, the image can then be detected without contact The reproduction of a figure can not be interpreted too narrowly, the playback of a sequence of notes can also represent such a picture, thus enabling the first participant to process the request for information without the second, participants gets access to data of the first one. The request is sent to the ^¬ ser instead of the communication protocol between participants entkop ^¬ pelt This leads the interaction of two devices of the first subscriber, namely treatment device and conversion means of the first subscriber, to the fact that a reply process, which is performed by the first subscriber, is physically separated from the network device with its associated participants. In a communication of participants of the network device via so-called sockets this meant that this least ^{¬ of} the first participant in the query direction at the treatment facility "ends" and only "continued" with the returned response, without the part of the socket access to data structures of the first participant takes place.

With regard to the method according to the invention, this means, mutatis mutandis, that a plurality of data processing devices are connected as subscribers, so that there is a physical connection between at least two subscribers of the network device, an information query is made by at least one second information requesting subscriber, The information ^{query is} first received by a first, information-giving subscriber and converted into a coded format by means of a ^handling device. The encoded and mapped information query is detected by at least one implementation limiting device of the first subscriber and then converted into a maschi ^¬ nenlesbares format, the converted information query is vorgehal- by the at least one first subscriber by a processing device by comparing the converted information query with a requested information component processed and the information query is below generating at least one answer information and return at least ei ^¬ NEN response information to the at least one second, informationsanfordern- the subscriber answers.

In both the arrangement and the method, the transmission of response information as a response to that part of the first party handling the network communication may take place via some type of handling that allows only unidirectional communication while avoiding physical connection. Preferably, it is at a Ausgestal ^¬ processing of the data processing device according to the invention, however, if the first subscriber processes the response information on the same path as the information request, which means that once again, first, for example, an encoding ^¬ te representation of the information takes place, which after detection in a then is to convert again present in clear text response information is. In that ^regard , the previous conversion device now forms the treatment device and the previous treatment device now the conversion device. These can then be the one equipped with the vorgese ^¬ Henen respectively, for the corresponding function technical means FIN mention part only in the text below.

An advantageous embodiment of the data processing arrangement can consist of having the treatment device of the at least one first subscriber convert the at least one information query into a graphically displayable format, wherein the at least one conversion device records graphically representable or displayed information queries and converts them into a machine-readable form. mat converts. The graphically representable format here forms a practically easy-to-handle example of a coding, which can be further processed without contact and without the need for further interaction between the treatment device and conversion device after imaging by means of an opti ^¬ cal detection.

An expedient embodiment of the data processing device may, in this connection, to provide the treatment device and the conversion device in each case with at least one display means and a recording medium, so that the conversion and transfer path operates in both directions ^¬ obligations. It can be provided for both directions and in principle any number of such representation and recording means to treat a corresponding number of requests simultaneously. It would also be conceivable to subdivide a query into various partial queries to be processed in parallel and to have these partial queries transferred to different means or to have different types of information queries processed by different means. Finally, it is also conceivable and preferred that the processing of both information retrieval and response takes the same route, ie first of all processing a treatment facility and then processing a conversion facility.

In a preferred embodiment of the data processing arrangement according to the invention, this can be at least one display means with at least one display unit and / or one graphics card. As a result, a graphical representation of the information request is realized, which, for example, is a sign-based enabled playback of this query. But there are also possible other forms of coding the query, such as a single or mehrdimensiona ^¬ ler barcode.

A specific data processing arrangement can also be designed, for example, with a presentation means formed by at least one graphics card whose memory contents can be read out and transmitted to the conversion device or the treatment device. Again, the memory content for physical separation of the participants is to be coded in a suitable manner. An actual unusual Liehe coding could merely meant as an example, as acoustic Codie ^¬ tion work, in which the transmission takes place by means of speakers and microphones, the "mapping" of the encoded format could then consist for example in a playback of a tone sequence. A handover to the respective imple ^¬ limiting device then would find it does not take place about as with a modem, the special only by the handling device-protocol in a secreting Versendevorgang, which then is free of contact detected by the conversion means.

An additional safety aspect, the apparatus and method can still better off secure, may in this case be to let the Inforamtionsabfrage provided in which to co ^¬ exploding or in the encoded format on the part of the treatment device with at least one inspection characteristic, such as a checksum or a checksum , which finally initiates further processing of the converted format. For example, the feature of the information retrieval asked question can be given through a mask were in which query information eingege ^¬ ben. In another variant, this feature but, for example, be added only at the entrance to the treatment facility.

In the negative case of the non-conformity of the inspection feature, the request is then rejected by the treatment facility, also here, for example, a corresponding response information can be generated.

Not only with at least one such test feature, but especially with such, the data processing arrangement according to the invention is suitable for a gatekeeper function in the context of general information request systems, which can fulfill a release function.

In an advantageous embodiment of the data processing arrangement according to the invention, for example, a separate communication channel is provided, which takes over the transmission of the encoded memory content of the at least one Gra ^¬ fikkarte to the conversion device, which subsequently reverses the coding in question by conversion into the machine-readable format.

Another preferred development of the data processing system may be to permit at least one of the recording means of the treatment device and the conversion device to optically record the information request or response converted into a graphically displayable format. ^Therefore , information acquired on the receiving means can be detected in a suitable manner and subsequently further processed if the receiving means is formed by at least one scanning unit or an optical sensor. so trained recording means can convey both item information of an information item and, after appropriate interpretation, for example by means of an OCR program, content information.

Also in the inventive method is based, as already mentioned, to ^¬ reliable and secure way to return the response information in which ers ^¬ th subscriber that the process steps are carried out in reverse order, so here is a coded, in particular graphic, imple ^¬ Zung of Information query is performed. There, too, the communication of the first is thus physically separated with the second party by the processing of the information query, that a contact-free detection of the coded imaged information retrieval by at least one takes place Umsetzungseinrich ^¬ of the first user.

In an advantageous variant of the method, which simplifies the communication between the subscribers, because it permits a clear assignment of queries, the information ^request supplied to the first subscriber can be assigned to an identification feature for assignment, which permits assignment to a specific second subscriber , This possibly to be encoded with identification feature may consist for example in a unique address of the querying, second participant, such as an IP address that is already exchanged during communication ^¬ over the Internet in the context of the protocol between communicating participants. A further advantageous variant of the process, which increases safety in the treatmen ^¬ development of the query can be based on the power supplied to the first subscriber information query is structured or structured by the first station such that each query part a unique position given in the encoding , in particular a graphical representation is assignable or is assigned. In the case of a two-dimensional representation, this also means an assignment of the type of information to an x / y coordinate that can not be influenced from the outside.

This can realize both an input form that already structured the information requests sent to the first part ^¬ participants in this way, the aforementioned structure can also restructure again regardless of the input format after receiving the query by the first subscriber, so that the structure in question, both in terms of the local as well as the content distribution to the outside need not necessarily be disclosed, which further increases security. In this way, a location in the Abbil ^¬ dung of information retrieval can be assigned, for example, a type of formatted content whose scope is very narrowly definable, so that an erroneous coding, depending on a certain, narrow tolerance level, a further processing of information retrieval in the sense higher security or prevented.

In a preferred variant of the method according to the invention, the information request supplied to the first subscriber can therefore be structured by means of an input mask, in particular an input mask provided by the first subscriber. If the coded format is a character-based format, an advantageous variant of the method according to the invention may consist of the information query displayed in one direction by a presentation means and the return response represented by a presentation means in the opposite direction after detection by the respective recording means an OCR

Process the program so that the relevant information from the imaged ^¬ th and recorded format can then be extracted in a simple manner again.

In order to facilitate the handling of the response for the requesting subscriber, for example with regard to clarity, a variant of the method can provide that the response transmitted back to the second subscriber can be displayed or displayed in clear data within a response mask.

The above refinements and developments can, if appropriate, be combined as desired. Further possible refinements, developments and implementations of the invention also include combinations of features of the invention which have not been explicitly mentioned above or described below with regard to the exemplary embodiments. In particular, the skilled person will also add individual aspects as improvements or additions to the respective basic form of the present invention, there is the important advantage in a non-contact interaction of a treatment device and a conversion device of the first subscriber to exchange an encoded Informa ^¬ tion query and / or a coded response information such that the processing of the information query and its translation into a response performed by the first participant are physically separate from the network device within which the participants are communicating. The invention is explained below with reference to embodiments in the drawing. In partially highly schematic representation here show the

Fig.l a first embodiment of a data processing device according to the invention with a informationsanfordernden second subscriber and an information indicative of the first subscriber, which are connected in a network device, wherein the information query is encoded by a treatment device and abgebil ^¬ det and detected by a conversion device and treated with a processing device that answers the information query by comparing it with an inventory of information; and the

2 shows a second embodiment of a flow diagram of a ^¬ he inventive method, which illustrates the processes occurring in a specific information query process steps.

In all figures, the same or functionally identical elements and devices - unless otherwise stated - have been given the same reference numerals.

In Fig.l is first recognizes a designated as a whole with 1 Datenverar ^¬ beitungsanordnung for exchanging information, in which a plurality of data processing apparatuses as a participant 10, 20, 30 are connected via a network device 5, wherein a second subscriber 20 asking a Informationsab- provides which a first party 10 receives to answer what is through Double arrows 11, 21 are illustrated, which indicate the relevant communication via the network device 5. The illustrated network device 5 is therefore connected in Fig.l with a first participant 10, which answers information requests. The ring-like representation of the network device 5 in FIG. 1 is arbitrary and is not intended to be limiting to a particular topology of a network.

The first station 10 is provided with a treatment device 12 here, which converts the at least one present in a machine readable format in- formation query in an encoded format and mapping in this coded For ^¬ mat. This coding takes place in the treatment device 12 of the first user 10 of the data processing device 1 of FIG. 1 in a character-based, graphic format, as can be seen from the detail section of FIG. 1, which includes a number of display devices 13 designed as displays is provided, in each of the two rows shown there every second installation. The display means 13 is opposite to each 15 pre ^¬ seen at the first station 10 designed as a scanner receiving means (and vice versa), is provided with which a conversion device 14 of the first subscriber 10 and which the formed off on the display means 13 content of the information query each optically detected here, and converts back to maschi ^¬ nenlesbares format. In this way, a non-contact Erfas ^¬ solution of coded, mapped information query takes place.

The unit of treatment device 12 and conversion device 14 shown in the detail section of FIG. 1 is not in regard to its positioning in a housing approximately in a housing of the first participant 10 rather, the devices 12, 14 with their display means 13 or recording means 15 can be arranged, for example, between the structure of the network device 5 and the first user 10, the first user 10 and the information base 50, or as a completely separate unit. In this case, a separate common arrangement may be provided, each with necessary control means, but these functions can also take over, for example, a function provided for this purpose member of the first part ^¬ takers.

The first station 10 also comprises a processing means 16, then processes the information retrieval concerned with matching with a maintained before ^¬ information stock 50 and thereby generates a Antwortinformati ^¬ on, this response information is fed back on the same path in the direction of the second subscriber 20 the, so that it first passes again the treatment device 12, which encodes the response information and converts it into a graphically representable format and images it by means of display means 13. The relevant image is again captured by recording means 15 of the conversion device 14 and converted back into machine-readable format, so that subsequently the first participant can transmit the response information as a response back to the second participant 20, whereby the information query is answered. Accordingly, both the information request and the response information in the first subscriber 10 of the data processing arrangement 1 pass through a stage in which the coding and mapping of the respective information takes place with a presentation means 13 of the treatment apparatus 12, after which acquisition and reconversion by means of a reception means 15 the treatment device 14 is performed. Treatment device 12 with display means 13 and treatment device 14 with receiving means 15 are therefore effective in the interrogation process in both directions, which explains the alternating, opposite arrangement of display means 13 and recording means 15 in both rows of the detail representation in Fig.l.

Turning now be seen there is a flow chart of the inventive method for operating a data processing arrangement 1, which is not shown here in greater detail and answers of which only the requesting second station 20 and the information component 50, against which the infor ^¬ mationsabfrage of Fig.2 is , is recognizable. The double arrow 121 of the second subscriber 20 with the symbolic representation of the provision 105 of the network device 5 reproduces the communication with the relevant network device 5 as part of the information request. Looking at a concrete example, one could think about an information ^¬ request of a customer to a company computer or a travel portal for infor- mation about or booking a flight at a particular time to a particular destination for this. Suppose, then, that client wanted a second party who can be any computer 20, book a flight with an airline, with the example assumed entranc ^¬ ben in a mask "flight 10.10. to Hamburg on 12.10. - with return flight -1 person - Economy class ", the relevant inputs should form the information request.

In a next method step, the receiving 107 of the information ^{query is} mapped by a first, information-providing subscriber 10, who is also in communication with the network device 5 and maintains an information stock 50, so that when the information request is matched, a response information by the first subscriber 10 can generate, which at the second participant 20 is returned. The above-mentioned concrete entering the flight desire as a request for information is thus received by the first part ^¬ participants 10 (step 107 of the process), this first subscriber "remembers (stores)" in addition to this can be regarded as a travel information Informationsab- question, moreover, also the IP address and an automatically assigned ^{query number of} the requesting subscriber 20.

In the next process step, a treating 109 of Informationsab ^¬ ask the part of the at least one first subscriber 10 by a non-illustrated treatment device 12 with the aid of a presentation ^¬ means 13 takes place, whereby the at least converted an information request in a coded format and displayed in this format becomes. Consequently, the konkre ^¬ th input with the flight request on a display as a display means 13 in ei ^¬ nem this assigned for each information in each field is displayed, so that a part of information of the information query a unique on the two-dimensional display position in the form of a coordinate or a field counter assignable is.

Hereinafter, the conversion 111 of the encoded and mapped information query is performed by a conversion device 14, not shown, by means of a receiving means 15 of the first subscriber 10, wherein the encoded information query is detected without contact and subsequently converted into a machine-readable format. The dotted line 115 recognizable between the handling step 109 and the translate step 111 is intended to provide non-contact sensing and physical separation of processing 125 from the remainder of the process

Communicate the participants 10, 20 symbolically. For this process, in the specific request for information with the flight request by a scanner as recording means 15, the means of representation 13 together with its content scanned, wherein in addition to the information to be converted also forwarded the information where on the means of representation 13, the respective information has been found ^¬ . The conversion device 14 of the first user 10 translates the coded graphic image information again into plaintext / clear data with the aid of an OCR program.

The processing 125 of the converted information request by the at least one first subscriber 10 by means of a processing device 16, not shown, comprises a comparison of the converted information requests with the held information stock 50. For this purpose, the aforementioned clear data is, for example, sent to an inquiry program for the specific information request connected database, which can match the specific information query with the information stock 50. For this purpose, the connected database can know, for example, on which coordinates of the screen which information is located. B. Place of departure is at y 15-30 - x 12-18, this information is assigned to the corresponding query fields. The same procedure is used for all other information.

The processing means 16 performs onsabfrage also answering 127 of the of information, said response information is generated that the two ^¬ th in direction informationsanfordernden subscriber is returned 20th In the specific case, the processing device 16 can accordingly generate from the query response generated by the query program and the database, the appropriate response information and feed it back in the direction of the second subscriber 20 requesting the information.

The sequence of the method in the direction of the processing device 16 not shown can be seen by the full arrows of Figure 2, after generating the Answer information this can be given back in a suitable way in the direction of the second party, a separate communication path 131 used for this purpose is indicated by the dash-dotted arrow. However, the return of the response information to the processing device 16 of the first user 10, not shown, can also take place in the same sequence as in the information query, which is indicated by the dotted arrows. This means present that the response information he ^¬ neut first a treating 109 with coding and mapping is subjected to and the response information shown then reacting 111 passes with detecting and converting before by the first user 10 by sending 113 to the second subscriber 20 as Response is transmitted.

Adapted to the specific case mentioned the flight request, this may be about context mean that the response information is sent initially returned to a display as a representation means 13 and this is then scanned again by a scanner than on ^¬ bearing devices 15th Again, a forwarding Po ^¬ sitions of the individual response information components takes place again and again an OCR program converts the coded, showing information back into plaintext. Back to the treatment apparatus 12 of the first subscriber, the response information may be the information requesting the second subscriber 20 again are provided, for example in the form of a now completed mask, the Ant ^¬ answer to the respective request number (see FIG. Above) in this pre-defined areas established.

Thus, 20 also by means of the method shown, a secure communication Zvi ^¬ rule abfragendem and antwortendem subscriber 10, characterized ensure that a non-contact detection of the coded imaged of information Onsabfrage or response takes place, and the processing 125 of the information ^¬ onsabfrage by the first participant 10 is physically separated from the communication of the participants 10, 20 via the network device 5. Although the present invention has been described by way of preferred embodiments before ^¬ standing, it is not limited thereto, but modifiable in a variety of ways. In particular, the invention can be varied or modified in a variety of ways without ^deviating from the gist of the invention.
