  • Patent number: 10609019
    Abstract: A method of establishing a secure channel between a human user and a computer application is described. A secret unique identifier (“PIN”) is shared between a user and an application. When the user makes a request that involves utilizing the PIN for authentication purposes, the application renders a randomly selected identifier. The randomly selected identifier is in a format that is recognizable to a human but is not readily recognizable by an automated agent. The randomly selected identifier is then presented to the human user. The user identifies the relationship between the randomly selected identifier and the PIN. If the user's input reflects the fact that the user knows the PIN, then the user is authenticated.

  • Patent number: 10425405
    Abstract: Systems and methods are provided for authentication by combining a Reverse Turing Test (RTT) with password-based user authentication protocols to provide improved resistance to brute force attacks. In accordance with one embodiment of the invention, a method is provided for user authentication, the method including receiving a username/password pair associated with a user; requesting one or more responses to a first Reverse Turing Test (RTT); and granting access to the user if a valid response to the first RTT is received and the username/password pair is valid.

  • Patent number: 9906511
    Abstract: Techniques of performing impersonation detection involve using encrypted access request data. Along these lines, an impersonation detection server stores historical access request data only in encrypted form and has no way to decrypt such data. When a new access request is received by a client, the client sends the username associated with the request to the server, which in turns sends the client the encrypted historical access request data. In addition, the server sends the client instructions to perform impersonation detection. The client then carries out the instructions based on the encrypted historical access request data and data contained in the new access request.

  • Patent number: 9672514
    Abstract: Systems and methods are provided for performing transactions and managing communications using a trusted third party. In one embodiment, a sender transfers an encrypted version of a file (such as a digitally encoded audio track, movie, document, or the like) to someone who wishes to receive it. The receiver computes a first hash of at least a portion of the encrypted data content, and sends the first hash to a third party configured to compare at least a portion of the first hash to at least a portion of a second hash. The receiver receives a file decryption key from the third party, and decrypts at least the portion of the received encrypted data content with the decryption key. In some cases, multiple hashes of the encrypted data content may be computed, each using a different portion of the encrypted data content.

  • Patent number: 9313179
    Abstract: Processing a query, includes, at a client, receiving a user-generated query having a plurality of recognizable terms, securing the user-generated query to generate an encrypted query, so that the plurality of recognizable terms generated by the user-generated query cannot be determined by a server, transmitting the encrypted query to the server, to perform the query on encrypted data comprising a mix of regular data and secure data previously provided by the client, wherein at least one of selection criteria of the query and identities of selected records of the query result cannot be determined by the server, and interpreting a result of the query provided by the server, and providing an output of the query to the user having the plurality of recognizable terms.

    Abstract: Homomorphic cryptography on numerical values in digital computing is described, including converting a numerical value encoded in a bit string of a first size to another bit string of a second size, which is different from the first size; encrypting the numerical value in the another bit string to produce a ciphertext; and storing the ciphertext.

  • Patent number: 8738387
    Abstract: A system and method is disclosed for determining a value of an element, having a k-th rank. The method discloses: calculating a total number of elements in a first and second dataset; prohibiting parties from accessing each other's dataset; ranking the elements within each dataset; computing a total number of elements in the datasets each having a value less than a test value; computing a total number of elements in the datasets each having a value greater than the test value; and setting the value of the element, having the k-th rank, equal to the test value, if the total number of elements having values less than the test value is ? the k-th rank minus one, and the total number of elements having values greater than the test value is ? the total number of elements minus the k-th rank. The system discloses means for practicing the method.
