  • Patent number: 10452857
    Abstract: Storage end points, whether they are local, remote, network, or cloud, such as DROPBOX and APPLE, present security issues for the general public and corporate consumers. These storage end points are not always encrypted. Even when the end user does perform encryption, the drawback to normal implementations is that the entirety of the file, the file key, and the key store are encrypted and stored in a single location. Computers can be hacked and encryption can be broken when given access and time. Disclosed is a system and method that enhances file level security by shredding the file, file pointers, and key store into parts, allowing the parts to be stored in different storage end points specified by the user.

  • Patent number: 10419416
    Abstract: Encryption and decryption techniques based on one or more transposition vectors. A secret key is used to generate vectors that describe permutation (or repositioning) of characters within a segment length equal to a length of the transposition vector. The transposition vector is then inherited by the encryption process, which shifts characters and encrypts those characters using a variety of encryption processes, all completely reversible. In one embodiment, one or more auxiliary keys, transmitted as clear text header values, are used as initial values to vary the transposition vectors generated from the secret key, e.g., from encryption-to-encryption. Any number of rounds of encryption can be applied, each having associated headers used to “detokenize” encryption data and perform rounds to decryption to recover the original data (or parent token information). Format preserving encryption (FPE) techniques are also provided with application to, e.g., payment processing.

  • Patent number: 10404699
    Abstract: An aspect of the present disclosure facilitates third parties/server system to perform batch processing of requests requiring authorization from resource owners for repeat access to resources. In one embodiment, a server system/third party selects a next request from a batch of requests, with the next request requiring a protected resource (hosted on a second party) owned by a owner/user (first party). The server system checks whether an access token is present authorizing access of the protected resource by the server system on behalf of the owner. If the access token is not present, the server system communicates in an offline mode with the owner to receive the access token. The server system then processes the next request by accessing the protected resource using the present/received access token.
