  • Systems and methods for encoding data
    Patent number: 8751819
    Abstract: A computer-implemented method for encoding data may include 1) receiving a request to encode the data using a cipher, 2) identifying an encryption key to be used by the cipher to encode the data, 3) generating, on a computing system, a non-random initialization vector for the cipher by identifying a unique identifier associated with the computing system, identifying information associated with the data, and concatenating the unique identifier with the information associated with the data to create the initialization vector, and 4) encoding the data with the cipher using the initialization vector and the encryption key. Various other methods, systems, and computer-readable media are also disclosed.
