Description

Method for the tamper-proof storage of changeable information, method for testing the tamper-proofness of information and device

[0001] The invention relates to a method for the tamper-proof storage of changeable information by means of a continuously expandable data set comprising superimposed data sets, wherein a first data set contains the changeable information and a first modified data set contains first modified information, and the first data set and the first modified data set are stored superimposed so that the first data set and the modified data set are stored superimposed in the continuously expandable data set in a traceable manner. Furthermore, the invention relates to a method for testing the tamper-proof nature of information using a respective hologram, wherein the information has been stored in a tamper-proof manner, in particular by means of the preceding method. Furthermore, the invention relates to a device for carrying out such methods.

[0002] Previously known methods for the tamper-proof storage of changeable information, which use a digital blockchain, for example, store correspondingly changed information components or changed data records of the changeable information digitally, continuously and interdependently, so that changes to the data records can be traced. Furthermore, it is possible to verify the corresponding modified information and the changes made to the information, for example, by comparing it with other information carriers within, for example, a computer network. However, these methods do not involve additional hardware integration and / or additional physical verification of access authorization to the storage system using hardware.

[0003] The object of the invention is to improve the state of the art.

[0004] The problem is solved by a method for the tamper-proof storage of changeable information by means of a continuously expandable data set from superimposed data sets, wherein a first data set contains the changeable information and a first changed data set contains a first changed information and the first data set and the first changed data set are stored superimposed so that the first data set and the changed data set are stored superimposed in a traceable manner in the continuously expandable data set, with the following steps: - Displaying the first data set on an initial display device so that a first optical image of the first data set is displayed, - Displaying the first changed data record on a first display device, so that a first modified optical image of the first modified data set is displayed, - superimposing the first optical image with the first modified optical image so that a first superimposed optical image is present, - generating a first hologram of the first superimposed optical image, so that a first superimposed hologram of the first superimposed optical image is present, - Storing the first superimposed hologram so that a first stored hologram is present, so that the changeable information is stored in a tamper-proof manner by means of the first stored hologram.

[0005] The core idea of ​​the invention is to display a superimposed data set consisting of a first data set with changeable information and respective modified data sets with, for example, modified parts of the data set, and then to convert the superimposed display into a hologram. The hologram of the respective superimposed optical images maps the superimposed information within the hologram and can then be stored. With this procedure, all previous changes to the data set are stored in the holographic representation in the data thus stored.

[0006] The following terms are explained in this context:

[0007] A "method for tamper-proof storage" describes a data processing method in which "modifiable information", i.e. information that can be changed or falsified, for example, by a user or a third party, is stored in such a way that unauthorized falsification by a third party is either prevented and / or manipulation by a third party, in particular by an unauthorized third party, is recognizable from the appearance of the information. Such "information" can, for example, be a computer file in which financial information is stored; similarly, personal data, medical data or other information can be stored for which manipulation must be recognizable and / or such manipulation is to be ruled out.

[0008] Such information is often stored in a continuous chain of data records, i.e., an increasing data volume, which in this context is also referred to as a "continuously expandable data volume." For this purpose, corresponding "overlaid data records" are stored, i.e., data records consisting of the respective originally existing data and further added changes, with each change being stored in a superimposed data record.

[0009] A "first data set" contains the changeable information, i.e. the corresponding original information or initial information, whereby a "first changed data set" and respective subsequent changed data sets contain or contain respective "changed information", i.e. for example change documentation. The respective data sets are stored "overlaid", i.e. in a data combination, a data addition, a data subtraction or another overlay method, so that the resulting data set of the continuously expandable data set contains both the original data and the correspondingly changed data.

[0010] This involves first "displaying" the first data set, i.e. physically projecting, showing or displaying it on an "initial display device", whereby this initial display device can be, for example, a display or a monitor that contains a corresponding image of the data set, i.e., pixels that are color-coded depending on the data elements. The result is then a "first optical image" of the first data set.

[0011] Furthermore, the first changed data set is displayed on a first display device, for example on another display, so that a changed optical image of the first changed data set is then displayed.

[0012] An "overlay" describes the physical superimposition of the corresponding displayed optical images, whereby, for example, a color mixture, a color penetration or a color overlay or a similar optical property is created.

[0013] A first hologram is then "generated", whereby such a "hologram" represents a method for recording and reconstructing a wave field, whereby the term hologram stands on the one hand for the method and on the other hand for a generated image of the wave field. In contrast to purely pictorial imaging, the intensity and phase of the wave field are reconstructed when reconstructing a corresponding hologram. This means that a larger amount of data can be stored in a hologram than in a correspondingly simple image. It should be mentioned in this regard that a hologram is generated in particular by illuminating an object with coherent light.

[0014] A "superimposed hologram" describes a hologram that is created from the first optical image and the modified optical image according to the previously described superposition.

[0015] The "saving" of the first superimposed hologram describes, for example, the storage of corresponding hologram information on a digital data carrier so that, for example, a file with the information contained in the hologram is generated from the superimposed hologram.

[0016] As a result, the changeable information is stored in the first stored hologram in a tamper-proof manner and contains, in particular, the information from the first data set and the first changed data set in its entirety.

[0017] In order to be able to store and track further changes to the corresponding data, for example, a second modified optical image of a second modified data set with a second modified information item is displayed on a second display device, a third modified optical image of a third modified data set with a third modified information item is displayed on a third display device, a fourth modified optical image of a fourth modified data set with a fourth modified information item is displayed on a fourth display device and / or a further modified optical image of a further modified data set with a further modified information item is displayed on a further display device.In addition, the first optical image is superimposed with the respective modified optical images and a respective hologram of a respective superimposed image is generated and stored.

[0018] Consequently, further modified data records can be added to the original data and thus to the continuously expandable data set or the continuously expandable data set, whereby corresponding changes and, for example, added information is stored in a tamper-proof manner.

[0019] In one embodiment, the superimposition of the respective optical images is carried out by means of a physical superimposition of the respective display devices, wherein the respective display devices are arranged in particular one behind the other and are designed in particular to be partially transparent or transparent, so that the generation of the respective hologram takes place by means of a joint imaging of all display devices.

[0020] Thus, for example, by "physical overlaying", i.e., for example, by arranging corresponding displays or semi-transparent displays one behind the other in a corresponding evaluation device, an additional security level can be created, for example by only allowing the reading and / or modification of the corresponding amount of data with a correspondingly designed physical device that is not accessible to third parties.

[0021] In particular, the respective display device is a digital display, in particular an LCD display.

[0022] In a further embodiment, the respective hologram is generated by means of a digital camera, a laser and / or a projector. Alternatively or additionally, the storage is carried out by means of a film, a crystal and / or by means of a digital data carrier, in particular by means of a distributed digital data carrier structure.

[0023] Using a digital camera, which can, for example, record and save corresponding wave intensities, simplifies the creation of the hologram compared to, for example, burning the hologram into a physical crystal. However, the hologram can also be burned into a crystal, for example using a laser, i.e. using bundled, parallelized light radiation, so that, for example, an additional physical encryption or security level is present and / or, for example, the modified data set within a crystal becomes physically transportable. The corresponding information can also be stored on a digital data carrier, for example on a USB stick, a solid-state drive or a hard drive.

[0024] In this context, a "distributed digital storage structure" refers, for example, to a network of computers and / or storage media, so that, for example, in the physically separate storage structure, for example at different locations, corresponding data volumes are available for comparison.

[0025] In order to check, when carrying out the planned or prepared changes to the data sets, whether the original data set of the continuously expandable data volume corresponds to a corresponding target, before the respective optical images are superimposed, the respective previous optical images are compared with a comparison image, wherein the superimposition of the respective optical images and / or the generation of a respective hologram is only carried out if the respective optical image corresponds to the comparison image.

[0026] Here, for example, a respective previous optical image can be compared with comparison information of a comparison image stored in a network, so that the validity of the previous optical image is ensured before the data set is changed.

[0027] The correspondence between the corresponding optical image and the comparison image can, for example, be achieved with appropriate error tolerances, so that in the event of optical falsifications due to contamination and / or faulty data transmission, the data information can still be changed.

[0028] In one embodiment, before storing the respective hologram, a comparison is carried out with a comparison hologram, wherein the storage of the respective hologram is only carried out if the respective hologram matches the comparison hologram.

[0029] Similar to the previous example, saving can only be carried out once the validity of the information modified accordingly and stored in the hologram has been ensured.

[0030] In a further aspect, the object is achieved by a method for testing the security against falsification of information stored in a falsification-proof manner by means of a method according to one of the previous embodiments, using a respective hologram, with the following steps: - Reading the hologram, - comparing the hologram with a respective comparison hologram or a text, - Validating the hologram if the hologram matches the reference hologram or the text so that the security against falsification of the information by means of the hologram is checked.

[0031] The core idea of ​​this method is to compare the holograms produced in particular according to the methods described above and thus to check and / or confirm the validity of the information against a comparison hologram, for example a duplicate of the hologram stored in a network or a reference hologram provided, for example, by a network.

[0032] The "checking" describes the comparison of the tamper-proof stored information with a corresponding reference, so that only if there is a match, for example, the tamper-proof stored information is released.

[0033] "Reading" describes, for example, the recording of the hologram, an image of the hologram and / or a digital representation of the hologram into a corresponding apparatus, device and / or, for example, a computer, so that a "comparison" of the hologram with a respective comparison hologram is then carried out optically, digitally supported and / or digitally. "Validating" the hologram in this context describes the release and / or description of the hologram as "valid", i.e., for example, matching or sufficiently matching the comparison hologram so that the authenticity of the tamper-proof stored information can be ensured. A hologram from a previous data set can also be used to serve as a filter for the data set to be checked.

[0034] In a further aspect, the object is achieved by a device which is configured to carry out a respective method according to one of the previously described embodiments for the tamper-proof storage of changeable information and / or for checking the tamper-proof security of information stored in a tamper-proof manner by means of such a method.

[0035] In addition to the methods described above, it should also be mentioned that storage, as is common for blockchain technology, can take place on a distributed digital data storage structure, for example on so-called "peers" within a network. This also enables a comparison of data records to check validity. A common method, such as "proof of authority" or "proof of stack", can be used for this. Likewise, an appropriately configured end device issued only to trustworthy users can have a seal which is additionally stored holographically and enables a comparison of authenticity or validity.

[0036] With regard to the devices described, it should also be mentioned that, as described above, an additional, in particular holographic, seal can also be used to prove the authenticity of the corresponding device.

[0037] The invention will be explained in more detail below using an exemplary embodiment. Figure 1 is a schematic representation of a Encryption arrangement for generating and storing a hologram and Figure 2 is a schematic representation of a Computer network for comparing correspondingly generated holograms in a computer network.

[0038] An encryption arrangement 101 has a laser 103 which is directed onto a mirror 105. The mirror directs the laser light 104 generated by the laser through a semi-transparent mirror 111 onto a mirror 107 and then onto a mirror 109. The laser light is then directed along an optical path 108 through a lens 117 and onto a sequence of LCDs 121, 122, 123 and 124. The laser light, which interferes with the images on the corresponding LCDs, then travels back along the optical path 108 via the mirror 109 and the mirror 107 onto the semi-transparent mirror 111 and is directed towards a lens 113 and a lens 115 onto a CCD camera 131.Within the semi-transparent mirror 111, the laser light 104 interferes with corresponding image information from the LCDs, so that a holographic image of the image information displayed on the LCDs 121, 122, 123 and 124 can be recorded with the CCD camera 131.

[0039] An original digital information is displayed on the LCD 121, for example the origin of a changeable information. Corresponding changed data sets are then displayed pictorially on the LCD 122 and subsequently with further changes on the LCD 123 and the LCD 124. An image of the LCDs 121, 122, 123 and 124 thus shows the original data information as well as three changed levels of the data information, whereby the hologram recorded with the CCD camera 131 is a sum of all changes It should be noted that the corresponding combination of the image information with the laser light to generate the hologram takes place along an optical path 110. The optical path 110, starting from the LCDs 121, 122, 123, 124 in Figure 1, is not shown at right angles and merely serves to illustrate the principle. For example, this optical combination can take place using mirrors, semi-transparent mirrors, prisms, or other known optical elements.

[0040] A network 201 is used to validate the information. The network 201 has a workstation 211 in the form of a personal computer, and peers 221, 223, 225, 227 and 229 connected via network connections 231 are also integrated into the network 201. If the validity of corresponding information stored in a hologram is to be queried, the workstation 211 sends the information to the peer 221, whereby the information is also sent to the peers 223, 225, 227 and 229. Only when the information is consistently validated by all participating peers is validity information sent to the workstation 211, so that the corresponding hologram and thus also the integrity of the data information can be validated.
