Abstract: Computer systems, such as a client and a server operably interconnected via a network, are subject to stress on computational resources due to an abundance of automated-user traffic. To improve resource functionalities and control the resources available to automated-agents, value information of valuable assets is encrypted such that a client must perform an algorithm for calculating a decryption key in order to view the unencrypted content. Wherein the encryption is tuned in such a way that any computational delay caused by the encryption is imperceptible to a human-user and largely perceptible to an automated-agent such that the need to determine if a user is an automated-user or a human-user is irrelevant.

Abstract: A customer submits a set of preferences including hardware specifications for instantiating a virtual machine instance. The virtual machine instance may be instantiated in a physical host computer system that does not conform to the set of preferences. The virtual computer system service may be configured to evaluate the specifications of the available physical host computer systems to determine whether any of the available physical host computer systems conform to the set of preferences. Accordingly, the virtual computer system service may further evaluate the available physical host computer systems to determine whether available physical host computer systems comprise available slots for instantiating the existing virtual machine instance. If the one or more available physical host computer systems have available slots, the virtual computer system service may migrate the existing virtual machine instance to an available physical host computer system in order to fulfill the customer request.

Abstract: Attacks, such as MITM and DoS attacks, on a distributed computing system may be detected by sending a work assignment to an execution device through a first communication channel. A report may then be received through a second communication channel of the work assignment received by the execution device. Information regarding the received work assignment may then be in view of information regarding the sent work assignment to determine whether an error, such as an MITM or DoS attack, has occurred. If the analysis indicates that the report does not include the sent work assignment, then a DoS attack may have occurred. If the analysis indicates that the work assignment received by the recipient does not correspond to the sent work assignment, then a MITM attack may have occurred. If an error has occurred, an indication might be recorded and/or other types of actions might also be taken.

Abstract: Techniques for managing digital assets are described that enable a principal to designate a plurality of users that will gain access and ownership of the principal's account that contains the various digital assets of the principal in the event of a transfer of assets. The account may be a network accessible account that maintains various digital assets of the principal, such as multimedia, applications, virtual machines, data, and others. In the event of a transfer, access to the account can be controlled by a cryptographic secret, where each of the designated users has been provided with a distinct share (part) of the cryptographic secret. A minimum number of shares of the secret are required before access to the principal's account will be granted. The minimum number may be configured by the principal in advance.
