Abstract: A printed document includes encoded content. The at least some content of the printed document is acquired and securely communicated to a support service. Information received from the support service is used to present user-readable content on a display. One or more portions of the encoded content are decoded for inclusion with the user-readable content, in accordance with an authorization of the user. Printed documents having encoded content may be distributed without security concerns due to the machine-based, authorization-driven nature of respective methods and apparatus.

Abstract: In a distributed system, a computer system responsible, at least in part, for complying with a cryptographic key usage limit for a cryptographic key, obtains results of cryptographic operations generated based at least in part on the cryptographic key and transmits the obtained results over a network. The computer system digitally signs the results and provides the results with digital signatures of the results. Another device intercepts the results and allows the results to proceed to their destination contingent on successful validation of the digital signature.

Abstract: Nodes in a distributed system utilize the same cryptographic key, where the cryptographic key is subject to a usage limit. The usage limit is allowed to be temporarily exceeded. When the usage limit is exceeded, results of exceeding the usage limit are corrected to mitigate the effects of exceeding the usage limit.
