Creating a secure searchable path by hashing each component of the path

A computing device comprising:

• one or more processors;
• and
• one or more non-transitory computer readable media storing instructions executable by the one or more processors to perform operations comprising:
• determining that a file includes an original path including multiple components;
• selecting a first component of the original path;
• generating a first hash value corresponding to the first component;
• determining that the first hash value is included in a dictionary that includes multiple index-hash pairs, each consisting of a hash value of a component in the original path and an index value corresponding to the hash value, wherein each index value in the multiple index-hash pairs is different than its corresponding hash value;
• retrieving a first index corresponding to the first hash value from the dictionary;
• then replacing the first component of the original path with the first index retrieved from the dictionary to create a modified path;
• sending, across a network to a server, a modified file comprising the modified path, the dictionary, a salt comprising a randomly generated number, and a hash function to generate the first hash value based on the first component and the salt;
• and
• determining usage patterns in multiple computing devices by searching the first index of other paths.
