Abstract
A global locality sensitive hash (LSH) database stores global locality sensitive hashes of files of different private computer networks. Each of the private computer networks has a corresponding local LSH database that stores local locality sensitive hashes of files of the private computer network. A target locality sensitive hash is generated for a target file of a private computer network. The global and local LSH databases are searched for a locality sensitive hash that is similar to the target locality sensitive hash. The target file is marked for further evaluation for malware or other cybersecurity threats when the target locality sensitive hash is not similar to any of the global and local locality sensitive hashes.
