    Patent number: 11055427
    Abstract: A cloud security system and method designed to protect users' data in case of accidental leaks in a cloud computing environment. Secured hashing of the names of folders stored on the cloud data storage are generated and persisted using multiple iterations of cryptographic hash functions along with a concatenated random number for each of the folder names, thereby providing protection against vulnerability of the folder names. The proposed system is a dual-layer framework consisting of a control layer and a data layer. The control layer is responsible for cryptographic hashing and persistence of the folder name, hashed name, salt, and iterations in a database. The control layer communicates with the data layer and provides the hashed folder names to persist the user data cloud storage.

  • Unsupervised topic modeling for short texts
    Patent number: 11030401
    Abstract: Topics are determined for short text messages using an unsupervised topic model. In a training corpus created from a number of short text messages, a vocabulary of words is identified, and for each word a distributed vector representation is obtained by processing windows of the corpus having a fixed length. The corpus is modeled as a Gaussian mixture model in which Gaussian components represent topics. To determine a topic of a sample short text message, a posterior distribution over the corpus topics is obtained using the Gaussian mixture model.
