Abstract: An ownership management system records an article ID, which is unique information for identifying an article, and an owner ID, which is information indicating an owner of the article, on a blockchain in association with each other, and generates a two-dimensional code from a hash value acquired from the blockchain at the time of recording, the article ID, and the owner ID. The ownership management system accepts the two-dimensional code, extracts the hash value, the article ID, and the owner ID from the accepted two-dimensional code acquires the article ID and the owner ID recorded on the blockchain by using the extracted hash value, determines a matching relationship between the article ID and the owner ID extracted from the two-dimensional code, and outputs the extracted article ID and the owner ID when it is determined that the matching is made.

Abstract: A set of virtual machines (VMs) with different guest operating systems installed is initially booted and prepared to facilitate rapid creation, or “forking,” of a child VM(s) for malware analysis of a software sample. Because malicious code may be packaged for a specific operating system version, subsets of the VMs may have different versions of the same guest operating system installed. Upon detection of a sample indicated for malware analysis, a child VM(s) running the appropriate guest operating system is created based on a corresponding one(s) of the set of VMs. A process in which the corresponding VM(s) has been booted is forked to create a child process. A child VM which is a copy of the VM booted in the parent process is then created in the child process. The sample is then sandboxed in the child VM for analysis to determine if the sample comprises malware.
