Abstract: A computer-implemented method is for tamper-evident recording of a plurality of executable items. Each executable item is associated with a data item verification fingerprint. The method includes computing an aggregated verification fingerprint from data item verification fingerprints using a one-way compression function so that the aggregated verification fingerprint has a first bit length. The first bit length is less than a total bit length of a concatenation of the data item verification fingerprints. The method further includes storing the aggregated verification fingerprint in a blockchain, attempting to execute an element of code, validating the element of code against the aggregated verification fingerprint, and, based on the validation, allowing execution or denying execution of the element of code.

Abstract: The present invention relates to the secure configuration of electronic devices, such as for example network-connected “smart” devices and appliances, collectively referred to as “IoT devices”. A computer-implemented method of secure configuration of at least one electronic device is provided. According to the method, the electronic device connects to a blockchain database; determines from said blockchain database a configuration block comprising block identification data, where the block identification data corresponds to device identification data, stored with the electronic device; obtains configuration information from said configuration block; and using the configuration information, conducts configuration of the electronic device.

Abstract: A computer-implemented method and a corresponding system of tamper-evident recording of a plurality of service data items are provided. Each service data item is associated with a data item verification fingerprint. A processing routine is conducted, in which an aggregated verification fingerprint is computed from at least a plurality of data item verification fingerprints using at least one one-way compression function, so that the aggregated verification fingerprint has a bit length, which is less than a bit length of a concatenation of the data item verification fingerprints. The aggregated verification fingerprint is then stored in at least one blockchain, so that a tamper-evident verification of each service data item is possible, while the storage of the aggregated verification fingerprint is decoupled from the service data items.

Abstract: A method and a system for interfacing a database system with a consensus system are provided. The method comprises at least the steps of creating a shadow table of a table of the database system; and for each row of the shadow table: serialization of data, stored in a current row of the shadow table; generating a data item verification fingerprint of the data; and providing the data item verification fingerprint to the consensus system.

Abstract: The present application concerns a method and a system of storing one or more service data items. To store and share in particular confidential data, the one or more service data items are partitioned into one or more data stores. The one or more data stores are stored. Metadata of the one or more data stores is generated and the metadata is stored in a metadata database.
