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: In an example, a method includes acquiring, at a processor, first object model data representing a first three-dimensional object. A portion of the first object model data representing an object region to be concealed may be identified using the processor. The first object model data may be transformed, using the processor, to determine second object model data representing a modified first three-dimensional object which is distended in the object region represented by the identified portion of the first object model data.

Abstract: A method tor regulating production of an object, the method comprising allocating access rights and a production quota to a user, the production quota to be fulfilled on an authorised production device using an encrypted unique job token embedded or comprised within or derived from the object and associated with the user and production device, receiving a user request to produce the object at the authorised production device, authenticating the user, decrypting the encrypted unique job token using a private key of the user and a private key of the production device, determining whether the production quota for the user related to the object has been met and on the basis of the determination, authorising the user request to produce the object at the authorised production device.

Abstract: According to one example, a method is described for accessing a composite document in which a trigger is received. A handling instruction for a content-part, from a composite document, and a status for the content-part, from a second computer, are retrieved. An action for the content-part is determined based on the handling instruction and the status, and the content-part action is executed. In the event that the content-part action is to revoke the content-part, the content-part is revoked. In the event that the content-part action is to synchronize the content-part, the content-part is synchronized.

Abstract: Examples associated with digital composition hashing are described. One example method includes receiving a digital composition file from a user. The digital composition file may include a top-level design and a hierarchy of sub-level designs. A hashed structure may be generated from the digital composition file, where a node in the hashed structure for the first sub-level design is generated based on hashes of sub-level designs below the first sub-level design in the hierarchy. The hashed structure and a hash of the digital composition file are stored in association with the user.

Abstract: Examples relate to providing keywords to generate policy conditions. Examples include a computing device to remove, from a corpus of documents, words that are common among classes in the corpus to create a reduced corpus. In some examples, the computing device is to identify a set of keywords for a particular one of the classes in the reduced corpus by identifying keywords that are common among documents in the particular class, and provide the set of keywords to generate a policy condition.
