    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.

    IPC: G06Q20/40

    Abstract: In an example there is provided a method to: communicate an offer of an item for sale to an entity based on an entity identifier, generate transaction data specifying the offer of the item for sale to the entity, the transaction data comprising at least the entity identifier, the item offered for sale, and a purchase condition for the item; and store the transaction data in a secure ledger.

    Abstract: A method for regulating document access, the method comprising providing a set of access keys for a user, respective ones of the keys providing different user access privileges for components of a composite document, selecting multiple nodes in a distributed storage system, distributing data representing N fragments of encrypted or unencrypted versions of the set of access keys and/or at least one of the individual keys and/or a symmetric key. K, associated with the user across N selected nodes of the distributed storage system, wherein the encrypted versions are encrypted using the symmetric encryption key. K, associated with the user, encrypting data relating to address information of the N selected nodes using a public encryption key of the user to generate a location object and storing the location object as a component of the composite document.

    Abstract: In an example, a method includes acquiring, at a processor, object generation source data representing a three-dimensional object to be generated in additive manufacturing. A dataset which is representative of an aspect of the three-dimensional object may be determined from the object generation source data. Digital security may be applied to the object generation source data and the dataset. The digital security applied to the object generation source data may be different from that which is applied to the dataset.

    Abstract: A system for protecting a three-dimensional (3D) model defining a 3D object may include a printing consumable, and a data element associated with the printing consumable. The data element defines an assigned association between the printing consumable and a 3D model. A method of protecting a 3D model via consumables may include assigning an association between a printing consumable and a 3D model. The association protects the 3D model based on availability of the printing consumable. The method may include determining whether the printing consumable is installed in a 3D printing device to allow for the forming of a 3D object based on the 3D model, and in response to a determination that the printing consumable is installed in the 3D printing device, permitting the printing of the 3D object using the 3D model and consuming of the printing consumable.
