Abstract: In one example in accordance with the present disclosure, an electronic device is described. The example electronic device includes a processor and a memory communicatively coupled to the processor. The memory stores executable instructions that when executed cause the processor to store data received from a first entity in a blockchain ledger based on a smart contract. The instructions also cause the processor to verify, with the smart contract, that a second entity is authorized to receive the data. The instructions further cause the processor to send the data to the second entity in response to verifying the second entity is authorized to receive the data.

Abstract: In an example there is provided a method for certifying transactions of a workflow for a workflow comprising a set of transactions and a permitted order of execution of transactions. The method comprises generating verification data in response to a request from a client to certify a transaction of the workflow on the basis of a secure ledger where the verification data certifies the validity of the secure ledger. The method further comprises communicating the verification data to the client. The secure ledger is determined on the basis of workflow transactions.

Abstract: In an example there is provided a method to access data records generated by a computing device, the data records specifying at least an event log of in-device code executed by the computing device. The method comprises applying pattern recognition to the data records of the computing device to determine if the computing device needs in-device code maintenance and performing maintenance of the in-device code on the computing device in response to the output of the pattern recognition.

Abstract: A three-dimensional (3D) printing device includes a processor and memory communicatively coupled to the processor. The processor verifies that a digital contract certified by an authorized party is authentic and applicable. The digital contract includes a process bound, a part bound for each part in a packed bed of parts, a time bound, and a cost identifier to define a cost of printing the packed bed that is based on the process bound, the part bound for each part in the packed bed of parts, and the time bound.

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.

Abstract: A callback, which may be assigned to a creation event of an application process, may be executed. In response to the execution of the callback, a data flow control object may be injected into the application process. The data flow control object may be to intercept a system call made by the application process and to control flow of data handled by the system call.

Abstract: According to one example, a method is described in which a computer system receives a composite document with at least one referenced resource location. The computer system decrypts the referenced resource location, determines if the referenced resource location requires loading, and determines if the referenced resource location is editable. In the event that the referenced resource location requires loading, the referenced resource may be loaded from the referenced resource location and decrypted. In the event that the referenced resource location is editable, the referenced resource location may be edited.

Abstract: A method and apparatus for encoding, in a simultaneous multiple security application, independently encrypted security data elements within a single matrix of blocks in a progressive barcode. The method and apparatus including, encoding information of a first data element within the matrix using black modules and, encoding information of a second data element within the matrix using color modules. The barcode being configured to be overprinted as it progresses through progressive states. The progressive barcode, resulting from the overprinting through the progressive states, masking the ability to conclusively determine the barcode in a previous state.

Abstract: In an example, there is provided a method for creating a workflow, comprising workflow tasks. The method comprises assigning workflow tasks to workers, according to an access control policy. The method comprises encoding as a transaction to a secure ledger that access to the workflow is granted to a worker to perform a workflow task and enforcing access control on execution of the workflow task according to the transaction encoded to the secure ledger.
