  • Patent number: 12395347
    Abstract: Techniques to index and search encrypted content are presented. A method includes assigning a unique encryption key to an organization (Org_Key) of which a user is a member, storing a first mapping of a user ID of the user to a resource ID of a resource, storing a second mapping of a first hash of the unique encryption key and the plaintext word to the resource ID, and storing a third mapping of a second hash of the Org_Key, the resource ID, and the plaintext word to a uniform resource locator link. A search for a given plaintext search word is performed by hashing the plaintext search word with the Org_Key to obtain the resource ID, and then hashing the plaintext search word, the resource ID and Org_Key, the result of which may map to a URL that points to the desired encrypted content.
