Title: DECENTRALISED DATA STORAGE
Abstract: A method of storing data preferably data that is particularly worthy of protection, e.g. security-relevant or personal data, within a network, in particular an external light network, the network comprising a plurality of decentralized EDP units each belonging to a light, in particular in the form of an external light, which units each have communication means, at least one sensor arrangement being respectively assigned to at least some of the EDP units, and the sensor arrangement of a first EDP unit recording data,  characterized in that  a data set which comprises the data recorded by the sensor arrangement of a first EDP unit or that has been generated from these data is stored distributed over a number of the decentralized EDP units and is at least partially deleted after the distribution over the first EDP unit.

text: A method of storing data preferably data that is particularly worthy of protection, e.g. security-relevant or personal data, within a network, in particular an external light network, the network comprising a plurality of decentralized EDP units each belonging to a light, in particular in the form of an external light, which units each have communication means, at least one sensor arrangement being respectively assigned to at least some of the EDP units, and the sensor arrangement of a first EDP unit recording data, characterized in that a data set (1) which comprises the data recorded by the sensor arrangement of a first EDP unit or that has been generated from these data is stored distributed over a number of the decentralized EDP units (2, 12, 3, 13, 4, 14, 5, 15, 6, 7, 8, 9, 10, 11) and is at least partially deleted after the distribution over the first EDP unit (5).
number: 2
text: The method according to Claim 1, characterized in that the recorded data are stored temporarily in the first EDP unit (5).
number: 3
text: The method according to Claim 1 or 2, characterized in that the complete data set (1) is only stored temporarily.
number: 4
text: The method according to any of Claims 1 to 3, characterized in that the data set (1) is broken down into data set parts (A, B, C, D) before or during distribution.
number: 5
text: The method according to any of the preceding claims, characterized in that the data set parts (A, B, C, D) are generated by copying parts of the data set (1).
number: 6
text: The method according to any of the preceding claims, characterized in that the data set (1) is stored distributed in encrypted form.
number: 7
text: The method according to any of the preceding claims, characterized in that the data set (1) is brought together on an EDP unit, in particular the first EDP unit (5), or on the superordinate entity upon a request of a superordinate entity.
number: 8
text: The method according to Claims 6 and 7, characterized in that at least one key required for the decryption is transmitted from the superordinate entity to the EDP unit (5).
number: 9
text: The method according to any of the preceding claims including Claim 6, characterized in that a key for encrypting the data set (1) is made available by a/the superordinate entity or is generated automatically.
number: 10
text: The method according to any of the preceding claims, characterized in that data of the sensor arrangement recorded at one point in time are processed on the first or another EDP unit to form a plurality of data sets ; wherein preferably the data sets of the plurality of data sets are stored distributed over the EDP units (2, 12, 3, 13, 4, 14, 5, 15, 6, 7, 8, 9, 10, 11) respectively encrypted to different degrees on the basis of a categorization.
number: 11
text: The method according to any of the preceding claims, characterized in that data recorded at at least another, later time are used with the previous data to produce the data set (1); and/or
that the network is in the form of a mesh network.
number: 12
text: The method according to any of the preceding claims, characterized in that the EDP units (2, 12, 3, 13, 4, 14, 5, 15, 6, 7, 8, 9, 10, 11) respectively comprise a controller for operating a light, via which controller the network communication takes place, wherein preferably the data set (1) is issued and/or distributed via the same or another controller of the light.
number: 13
text: The method according to any of the preceding claims, characterized in that each part of the data set (1) is provided with a UID and/or a time stamp; and/or that the data set (1) is compressed prior to distribution; and/or that the sensor arrangement has a 2D or a 3D camera, the data of which are analyzed in particular by image processing software of the EDP unit; and/or that the distribution of the data set (1) is undertaken by the first EDP unit and at least another EDP unit.
number: 14
text: A light for implementing a method according to any of the preceding claims, the light having an EDP unit (2, 12, 3, 13, 4, 14, 5, 15, 6,7,8,9,10,11) with at least one controller for operating the light and means for communicating with other EDP units and/or a superordinate entity and comprises a sensor arrangement assigned to the light, characterized in that the controller is designed to distribute a data set which contains data recorded by the sensor arrangement of a first EDP unit or which has been generated from these data, over a number of the other EDP units (2, 12, 3, 13, 4, 14, 5, 6, 7, 8, 9, 10, 11), and then to delete these at least partially on this first EDP unit.
number: 15
text: A network of lights, characterized by a plurality of lights according to Claim 14.
