Abstract
A computer-implemented method for generating probabilistically searchable messages includes obtaining, by a computing device, a textual message. The method includes extracting, by the computing device, from the textual message, a plurality of words. The method includes cryptographically hashing, by the computing device, each word of the plurality of words. The method includes mapping, by the computing device, each cryptographically hashed word to a plurality of tokens. The method includes generating, by the computing device, a set of tokens associated with the textual message, the set of tokens including each plurality of tokens associated with each cryptographically hashed word. The method includes storing, by the computing device, the set of tokens associated with the textual message in metadata associated with the textual message.
