Abstract: In an example, a data structure comprises a first genesis record having an associated authentication value and a plurality of subsequent records arranged in an order, wherein at least one subsequent record includes the authentication value associated with the first genesis record and an authentication value associated with another record in the data structure. A method may include designating one of the subsequent records as a second genesis record, acquiring an authentication value for the second genesis record, deleting at least one record preceding the second genesis record in the data structure and adding a further record to the data structure wherein the further record includes the authentication value of the second genesis record and an authentication value associated with a directly preceding record in the data structure.

Abstract: Object model data modification is described in which object model data defining a three dimensional model to be generated by a three-dimensional printer may be obtained. Data relating to a first sensitive portion of the model may be obtained, the first sensitive portion representing a portion of the model to be concealed. Modified object model data in generated, the modified object model data including a first version of the three dimensional model that is represented in a first pre-processing application without exposing the first sensitive portion, and including the first object model data defining the three dimensional model for printing by a three-dimensional printer.

Abstract: Examples of devices are described. In some examples, an electronic device includes a processor to generate a public key associated with an installation of a program. In some examples, the electronic device includes a communication interface to instruct a computing device to create an identity block in a blockchain based on the public key. In some examples, the communication interface is to send program information to a verification device to produce a verification block associated with the identity block in the blockchain.

Abstract: In an example, print apparatus comprises a security services engine to perform cryptographic services. The security services engine may receive a request for a cryptographic service and validate that the request is an authorised request. On successful validation, the security services engine may perform the cryptographic service by acquiring a first key, acquire an associated first key identifier and may output the first key identifier.
